The network discusses a short landing fighter Su-57 in the suburbs

The network discusses the quick and short landing of the latest Russian Su-57 fighter. This kind of landing was made in Zhukovsky near Moscow, where the next International Aerospace Salon - MAKS-2019 opens.

The fifth-generation Su-57 aircraft performed a training flight before the opening of a representative cabin. Earlier it was announced that for the first time the Su-57 will be demonstrated not only in flight format, but also in terms of the static exposure of the MAX-2019.

The Su-57 pilot with tail number 054, landing, released brake parachutes even before the aircraft landing gear touched the surface of the runway. As a result, the full run of the fighter on the runway did not exceed two hundred meters.

The whole difficulty with using brake parachutes before touching the runway is primarily that the pilot must literally feel the moment. If the brake parachutes are released earlier than this moment, then the aircraft may lose speed to a critical point. In turn, this can lead to negative consequences, since the reduction will go into the emergency mode.

The development of this method of releasing brake parachutes was carried out in Soviet times. The main task of the pilot is to level the plane and the height is about 2 m above the ground. So, for example, a similar landing option was practiced on MiG-29 fighters. Personnel:

Comments

[Zaurbek]

There were shots where the pass planes included reverse before landing. In normal mode. More Soviet type Yak40 or IL62.

[Wedmak]

Reversing everything is controllable, but a parachute? In fact, the release of a parachute is a blow to all the power elements of the aircraft with a sharp decrease in speed. You can poke your nose if you do not choose the right moment.

[Ka-52]

In fact, the release of a parachute is a blow to all the power elements of the aircraft with a sharp decrease in speed. You can poke your nose if you do not choose the right moment.

firstly, the release of a parachute in the air is a standard situation, not an emergency. It is used to reduce mileage, because excludes the distance required when opening the parachute on the run (about 300m).
secondly, the blow is designed, it is not possible to exceed the load. The braking force is proportional to the square of the speed of the aircraft, therefore, on hold and immediately after touching the speed does not differ too much
thirdly, do not bump your nose, because the diving moment is countered by the automation. And the video shows that the drying is with a positive pitch.

[Wedmak]

What is the standard if not used?

therefore, on hold and immediately after touching, the speeds do not differ too much

This may not be enough for the development of a non-regular situation.
Automation is automatic, but the maneuver is still dangerous. The pilot must be very experienced and the weather calm and calm.

[Ka-52]

What is the standard if not used?

use what is most effective. If the length and condition of the GDP allows the release of a parachute while jogging, then is it worth pulling the car again? But there may be other situations and conditions. For example, short GDP.

This may not be enough for the development of a non-regular situation.
Automation is automatic, but the maneuver is still dangerous. The pilot must be very experienced and the weather calm and calm.

any maneuvering is potentially dangerous. Landing is no exception. But they sit down, sit on the deck, sat on a gas jet of vertical thrust. Many such examples of dangerous maneuvering.

[Avior]

In fact, what you wrote is the standard landing options.
And airplanes of special design.

[Ka-52]

In fact, what you wrote is the standard landing options

if the question is for me, then I did not write about the standard version. It was said that this is not an emergency. That is a pilot controllably used PTK-6M (or whatever he has there as a vocational school) according to the flight plan.

And specially designed planes

what special design? For what? Where was that said?

[Avior]

. But they sit down, sit on the deck, sat on a gas jet of vertical thrust.

Native landing options for aircraft specially designed for this design.
But for example, landing on the deck and taking off from it an airplane for which this is not regular.
Nothing emergency, but do not use - the risk is too high.

[Ka-52]

Native landing options for aircraft specially designed for this design.

I don’t understand what is the design problem? Why do you consider this a prerequisite for a flight accident? Landing speed on alignment and immediately after touching the rear pillars is almost equal. Therefore, there is no special overload on power elements from an earlier operation of a vocational school. The vertical speed is also not exceeded (and how will it be exceeded if alignment occurs at a height of 1-2m?). In general, even with a standard landing, excess loads on racks (up to 2,5) were, if not ordinary, but not uncommon. The PLP is issued and forward - to the TEH if the corrugation has gone

[Avior]

Those examples that you cited relate to the landing of specifically designed aircraft, which is precisely aimed at reducing risks and preserving the resource.
The s-130 had a whole program of landings and take-offs, not a single catastrophe — nevertheless, no one uses it as a regular one.
If everything was as simple as you write, you would have used it as a regular one for a long time.
And the technical details within the framework of the forum are unlikely to be so easy to discuss, especially taking into account the statistical nature of some factors, for example, the probability of a pilot's error leading to an accident, or the statistical probability of an accident in case of an error. After all, not every mistake leads to an accident, and this can only be taken into account statistically, which we obviously cannot do.
Almost the same speed is also not an argument, the dependence of the force on the speed is quadratic, not linear.
That is, at a speed of 200, the force is proportional to 40000, and at a speed of 250 it is proportional to 62500 with the same parachute.

[Ka-52]

If everything was as simple as you write, you would have used it as a regular one for a long time.

wait, wait. Situations are different. As in one direction or another. Let me give you an example, for the Tu-22 RLE, a strip of 3000 is recommended. But landings at 2500 were and have been more than once.

[Avior]

But I’m not saying that this cannot be done in principle
But in normal mode they will not use it, in my opinion.

You can poke your nose if you do not choose the right moment.

And with the wheels to attach to the strip so that "Mama Do not Cry"!)

[Miron]

If you turn off the engines, it will work out.
In the meantime, the engines are running, and can be released at 5 meters. Sailing of the planes is no less and no more, but the quality is increased, since the negative force in the longitudinal axis is compensated by the quality increment due to the bottom effect. That is, in general, this is an aerodynamic effect that can be discerned only if you have developed abstract thinking. Otherwise, years of testing at TsAGI.

[Errr]

Quote: Miron

since the negative force in the longitudinal axis is compensated by a quality increment due to the bottom effect

I understand that you mean the screen effect ...

[Miron]

I mean the flow of air that generates a parachute. There is a bottom effect, which is usually perceived as a barrier. But in this case, in combination with the changed nature of the air jets, he becomes an ally. And, by the way, it eliminates the effect of crosswind, that is, makes the entire landing process far more manageable.

[Miron]

That's what I meant.
http://bourabai.ru/physics/1125.html
In the case of the release of parachutes, before the car touches the strip, the picture changes to the opposite. Instead of disruption of the boundary layer and resistance, quality arises due to the reverse flow of the air stream.

[NKT]

In the Yak-40, it seems, only the medium engine has a reverse, the other two work just the same, only the system blocks gas on them ...

[pafegosoff]

I confirm. In RLE Yak-40, the inclusion of reverse when landing at a height of 5 meters. Well, I have observed this since 1974 (only Americans and Japanese did not study on the Yak-40). I don’t know if I switched on the reverse before touching the Tu-154 in 1977, when I was driving Pierre Trudeau (the daddy of the current jerk-prime minister) to us, but if he pulled up to the prescribed 600 meters from the end, he would have gotten himself into a squally gate of a thunderous cold front ... In general, the skill of pilots can surpass the anticipated capabilities of airplanes. The same An-2 can land in the "parachuting" mode at a true speed of 50 km / h, like the famous "Storch" (Fieseler Fi 156 Storch), which inspired Antonov even before the war.

[AU Ivanov.]

For the sake of fairness, I would like to note that "Storkh" inspired not Antonov, but Yakovlev to his Yak-12.

[pafegosoff]

Yes, I read, I read "The Purpose of Life" fifty years ago. But the Yak 12 did not mention: there were no such shock absorbers and a lot of things on the Yak-12. Back in school, we had a lot of these Yak-12s.
They flew glider tugboats, post offices and air taxis (1960s). By the way, from the memoirs: on the Yak 12 at the ends of the wings were ribbons. What for? I do not know.
Why am I talking about the An-2? Because it is love ...

[AU Ivanov.]

Ribbons on the wing? On clamps it is known. To take off before takeoff did not forget.

[pafegosoff]

No, in flight. Moreover, not at the holiday. Maybe for some identification. Postmen had tapes in the 1960s. I clearly remember. Same in size as pennants. On the clamps and plugs are red flags of 30 centimeters. Well, okay. By the way, about twenty years ago we had a decommissioned Yak-12 in our neighboring yard.
Touching the Su-57 and parachutes. There, probably, pulls like an aircraft carrier. Overload and retina ...

[Civil]

Where is the video itself? It would be interesting to see, and the new Su-57s are not ordinary combat pilots.

[Ded60]

Not sure, but, in my opinion, I read that reverse can be turned on only with a certain load on the chassis, that is, only after touching the ground ....

[Sivka burka]

in Boeing and Airbus, turning on the reverse before landing is possible, but the actual operation only begins after crimping the front pillar.
I suspect that on Soviet aircraft it turns on in a similar way.

[ddd1975]

Quote: Zaurbek

In my opinion, he still hit the GDP well, only a good chassis absorbed the "blow". And in the next second it was already started to swing to the sides because of the parachute, the pilot reacted in time. So the maneuver is quite dangerous and not regular.

Bogdan has repeatedly said that the SU-57 forgives much of the pilot that other fighters will not forgive. No wonder this is a fighter of a NEW generation. Hence, I conclude that such a landing is not only full-time in general, but also usual for specifically SU-57.

Meanwhile, few people know that, for example, a combat aircraft was flown over if it had stood idle for 30 days, and also after replacing the engine, 100 and 200 hours of routine maintenance in the TEC regiment. and only with specially trained crews. To transfer the aircraft to the aircraft repair plant and fly there, (Diaghilevo airfield or Bila Tserkva) crews were appointed not lower than the deputy squadron commander.

In the KBP of combat pilots of fighter aircraft, there is no such exercise ("short landing" with premature release of TP in the air). And the design bureau of the Su-57 aircraft is still being written ..
This is only practiced by test pilots, in particular, Bogdan "says" on the video.
About airmen .... there were regular airmen who had reached a certain level of flight training and were appointed by order of the regiment, after a test flight with one of the inspectors "from above". And not some kind of special training.
Any pilots were engaged in ARZ haulage, not necessarily even with the 1st class .. After the repair was completed, the board was first flown into the air and all the flights were carried out by full-time test pilots of the ARZ itself (and now), and only then regimental ones arrive, do two control flight and home)

Yes, he can fly with Avik. J. Ford has a landing deck of about 300 m, and even during take-off / landing the Avik rushes at 30 knots against the wind. Already consider can sit down. And if you hook the hook then there’s no problem at all, Well, the catapult will launch it 100%. Here Su33 without a catapult from a springboard flies.

Quote: ZAV69

And this looks like a hint: it can fly from Avik and sits on it

in its current form - no, it cannot. After improvements, it’s possible.

Not to mention the work on the corrosion resistance of the airframe, it will be necessary to at least modify the chassis (to make it more energy-intensive and durable, since the approach glide path is steeper and the landing of the landing gear on the deck is common), for the same reason - to strengthen the airframe, and also due to the installation of a hook (deck aircraft is experiencing greater overload). Well, to finalize the avionics - navigation over the sea has its own peculiarities, you need to find your aircraft carrier up to a kilometer above the space without obvious reference points, there are no alternate airports at sea.

[ZAV69]

All these issues are resolved. And the avionics probably do not need to be further developed, with a modern range, the probability of flying over the sea is quite high, most likely everything has already been taken into account

[Grigory_45]

Quote: ZAV69

probability of flying over the sea

it’s not just about flying over the sea. There should be equipment to ensure interaction with shipboard electronic systems, as well as to drive to the ship and approach the aircraft carrier’s deck

[E.S.]

The current state of corrosion protection is unknown to you, the content of design specifications for design is also unknown, the energy intensity of the chassis racks from open sources cannot be determined, as well as the characteristic resonant frequencies of mechanical vibrations. On the basis of what you make such a statement - it is unknown, but there are two options: either this is an irresponsible statement or disclosure.
But with the F-35, the situation is more understandable - when taking off from the catapult, the nose landing gear jumps very well, and the pilot hits the back of the head against the headrest, which affects the expensive helmet and its contents

[Grigory_45]

Quote: E.S.

Based on what you make a similar statement

based on the fact that, according to known information, the deck version of the Su-57 was not developed.
Su-57 was created for operation from conventional airfields. And this is quite logical.

There is no need to push extra cargo for it on a land plane, which also complicates and increases the cost of the car. There will be TTZ for the deck version - they will make the deck. Just as Su-27 was made from Su-33, MiG-29KR from MiG-29.

It is very strange that questions arise on such comments. Leads to bad suspicions

it’s good that they don’t hate snot, and this is the main thing .. It is clear that the big positive pitch and the pilot is clearly waiting for something, his nose does not lower to the runway. So this is a planned event. Only the height is too big, landing on deck turned out to be overload.

[Potato]

All fighters that land "nicely" at MAKS have a "large positive pitch". And nobody canceled the branded rental on the rear pillars. But here the parachutes were clearly out of the question. If the parachute on landing will fly out with missiles and bombs from the combatants, then this will not lead to good!

[Ka-52]

All fighters that land "nicely" at MAKS have a "large positive pitch". And nobody canceled the branded rental on the rear pillars. !

before landing, there is always a positive pitch, because the plane must sit on the C-pillars and only then lower the front "leg". Ideally, there is no need to forcibly lower the front wheel unless the landing speed is exceeded.

But here the parachutes were clearly off topic. If the parachute on landing will fly at the combatants with missiles and bombs, then this will not bring to good

these are your fantasies. The parachute can and is produced by the pilot. What is it about missiles? Landing speed and vertical descent speed are calculated based on the weight of the aircraft (with fuel and weapons). In general, for a standard en-route flight, all this is in the "flight plan".

the braking parachute attachment site should collapse, providing a parachute discharge, at a speed of about 340 km / h (plus or minus) The parachute is dropped when the load is exceeded, or, otherwise, when a certain speed threshold is exceeded.

[Eug]

So I about the same when exceeding the speed of release of the brake parachute, it simply breaks. Paratroopers (they are also paratroopers), the technician and the mechanic of the sideboard then, for a long time, inventively mumble ...

I confirm. In RLE Yak-40, the inclusion of reverse when landing at a height of 5 meters. Well, I’ve watched this since 1974 (only Americans and Japanese did not study with us on the Yak-40).

and how do you assess how successful the Yak-40 and Yak-42 were (as I recall, the Yak-40 had some problems)
and how realistic would it be now to establish mass transportation at their base at distances of 200-400 km, competing with buses?
in my homeland during the Soviet era there was a small airfield in the city where the Yak-40 and 42 flew to Krasnoyarsk (about 200 km) and in general this was very competitive in terms of price and convenience to the same flight on the Lviv bus, especially since the airport was right in the city - leaving the samik in 5 minutes already got into the trolleybus.

The Yak-40 was unsuccessful primarily due to fuel consumption. Yachonka was called the "kerosene fighter" for this. And so - a reliable, easy-to-operate machine. Overwhelm him and there would be no price for him. It seems like the Yak-40 was tested with two Honeywell TFE731 engines instead of three native ones and a composite wing.

And this looks like a hint: it can fly from Avik and sits on it

in its current form - no, it cannot. After improvements, it’s possible.

Not to mention the work on the corrosion resistance of the airframe, it will be necessary to at least modify the chassis (to make it more energy-intensive and durable, since the approach glide path is steeper and the landing of the landing gear on the deck is common), for the same reason - to strengthen the airframe, and also due to the installation of a hook (deck aircraft is experiencing greater overload). Well, to finalize the avionics - navigation over the sea has its own peculiarities, you need to find your aircraft carrier up to a kilometer above the space without obvious reference points, there are no alternate airports at sea.

Passage with navigation at sea and "find an aircraft carrier at sea" is simply incomparable, simply incomparable!

I’m not a specialist in the flight business, but I can’t see anything extraordinary in this landing, the pilot acted within the permissible limits, there was no emergency, or is there any flyer who, as a pro, clarified whether the pilot made a mistake?

[Dmitry Leontiev]

Dangerously. Around a gust of headwind at this moment? A sharp loss of speed, deprivation of lifting force and a fall from a two-meter height. And then, a pitching torque can occur - the parachute is attached not to the center of mass of the aircraft, but to the tail.
Why not just make larger parachutes - to slow down faster? Just make a higher attachment point. If you attach a huge parachute and make a fastening point at the top of the keel (specifically so that it can brake sharply), then when you open the strip there will be a certain moment of nose lifting - but not very strong. But a huge parachute will stop the plane instantly.

do not fantasize. what does the impulse have to do with it? a headwind gust can only "hold" the plane in the air, providing additional lift, and not decelerate. A sharp loss of speed from what? Do you think that the parachute stops the plane like a galloping horse instantly? Nonsense, it provides extra braking. The landing speed has a corridor - for example, from 250 to 320 km / h. Therefore, when the PS decreases to the lower limit, it is not an emergency, in extreme cases you will get a "goat". Pitch torque, what is this term?

just along the axis of the center of mass

on the contrary, the domes are breathable to remove excessive jerking, provide stability and prevent swaying.

then when you open the strip there will be a certain moment of nose lifting - but not very strong.

Why is this at all? vocational school is produced after brake application. And A brakes can be applied only after lowering the front foot onto the strip. Where are you going to turn up your nose?

Therefore, when the PS decreases to the lower limit, it is not an emergency, in extreme cases you will get a "goat". Pitch torque, what is this term?

And you look carefully at the video of the landing of an instant - immediately after opening the parachute the lifting force drops so much that it almost falls into the lane - when viewed from the rear, this is very noticeable. The oncoming gust of wind means a sharp increase in lift - the aircraft from this can raise higher. And the parachute, which opened at this moment, will be completely inappropriate - there may be a fall from this height from a lack of speed. In short, this is a risk.
And the twisting moment - this means that if the pitch of the aircraft in relation to the horizontal is significant, the thrust of the parachute (and it is horizontal) will force it to lower its nose sharply - that is, to align along the horizontal axis.

just along the axis of the center of mass

There are many axes passing through the center of mass. When the plane is landing, it has a certain positive pitch, and the center of mass path is not on the same axis as the parachute attachment point - which means the parachute will tend to align the plane along the axis of its trajectory - and it is descending - that is, the nose will go down.

on the contrary, the domes are breathable to remove excessive jerking, provide stability and prevent swaying.

In the air, such a parachute, of course, cannot be opened. But after touching, he will stop the plane much faster.

Why is this at all? vocational training is issued regularly after applying the brakes. And A brakes can be applied only after lowering the front foot onto the strip. Where are you going to turn up your nose?

I mean, for a large parachute, you will need a higher attachment point - so that it does not touch the ground. It will be located above the horizontal axis passing through the center of mass of the aircraft, which means the parachute will tend to lower its tail. (By the way, when such a parachute is triggered before touching, it will be close to the axis of the trajectory of the center of mass - that is, the twisting effect will be minimal).

I saw and did not see anything critical. For all my service time at 341 Tbp, I have not seen enough landings of any kind. Each take-off and landing was filmed and demonstrated to the entire flight crew the next day. Therefore, there is nothing even close to serious overload in this landing.

A twisting moment - this means that if the pitch of the aircraft in relation to the horizontal will be significant

do you bring in some terminology? There is a twisting moment in the structural elements. Twisting, and even in relation to this situation - it is not clear what you wanted to say.

which means that the parachute will seek to align the plane along the axis of its trajectory - and it is descending - that is, the nose will go down.

lowering of the nose when jerking is countered by either automatic or RUS. The pilot is not a dummy doll and can quite cope with such an evolution.

In the air, such a parachute, of course, cannot be opened. But after touching, he will stop the plane much faster.

what does air or earth have to do with it. I clearly wrote (and this was not born out of nowhere) that an airtight parachute will not be stable, transmitting its fluctuations to an airplane. What are you making up? The vocational school system was developed by engineers, not amateurs.

Yes, no one talks about an airtight parachute. I’m talking about the fact that a parachute can be made simply more - if you need to slow down the plane faster.
What determines the size of current parachutes? - The height of their attachment points for an airplane traveling on the ground; - with a large radius, he will cling to the surface. So for a larger diameter parachute, you just need to raise the attachment points higher. Actually, if you compare it with Mig, from the video given in the article, it can be seen that this was already applied on the Su-57 - there the parachute mount point extends higher. And the modernization potential on this, I think, is not finished at all - it can be advanced even higher - and parachutes can be made even larger. It will be safer than opening them in the air. It's my opinion.
And your "why are you inventing" gives you a retrograde. The desire to optimize everything and everyone cannot be blamed - it should only be encouraged. And a person who has consciousness - who understands that it is from the desire of mankind to improve everything that how quickly the world will change for the better - will never say such things. Man must always invent improvements - in this he must differ from the animal - which is devoid of the desire and ability to rationalize. And if you rely only on other people responsible for certain things (it doesn't matter, designers, politicians, managers, officials, high-ranking bigwigs, etc.) - this is just stupid self-deception. Not a single design bureau, consisting of a numerically limited team, will not take into account the volume of relevant factors and various possibilities that the whole society will bring in - give it that opportunity. An idea, necessary for something important, instead of those looking for it, with a predominant probability, can be sent to the head of a completely stranger; and the principle "why are you making this up ?!" instead of "pass the idea, don't bury it in the ground!" - will simply make it ultimately impossible to implement any important improvement normally.
Specialists can always separate inappropriate ideas from adequate ones. And to neglect the very possibility of communicating ideas is inadequacy.
I am talking about this because it is my main topic, which is now extremely important. Mankind needs the Activation System of its Mind. It’s just about this - about expanding the development team of the entire meta-system of the human world, with all its technologies, to the size of all mankind, transforming it into a single Intelligent Thinking System through this Central Technology.

Based on what you make a similar statement

based on the fact that, according to known information, the deck version of the Su-57 was not developed.
Su-57 was created for operation from conventional airfields. And this is quite logical.

There is no need to push extra cargo for it on a land plane, which also complicates and increases the cost of the car. There will be TTZ for the deck version - they will make the deck. Just as Su-27 was made from Su-33, MiG-29KR from MiG-29.

It is very strange that questions arise on such comments. Leads to bad suspicions

Now you are setting out your vision of the design process, based on the study of network fiction as applied to the previous generation technique, constructed from other structural materials, by designers whose design school is significantly different from the current one.
I repeat, you do not know the design specifications for the design and you do not know the degree of conformity of the TK product

[Dmitry Leontiev]

In general, no matter what they say, and if we are talking about a military or rescue aircraft (all kinds of quick response techniques and minimal dependence on external infrastructure), then he is simply obliged to be able to take off and land without any lane at all - that is, wherever and whenever. This means that its more expedient layout - vertical landing on the tail supports - and vertical take-off from them.
For this, powerful engines are needed that can lift the entire curb weight of the aircraft and adequate software that allows it to land vertically at a given point and take off from it. At the same time, such a heavy and complex element as a sliding chassis disappears from the structure - which makes it much easier and more reliable.
As far as I know, there have been attempts to build such devices, but for a long time - when there were no engines of the necessary power for this, nor, moreover, smart and fast control electronics. And they were abandoned. Now technology is already quite possible to create such devices. They do not require any strip and can be based anywhere, anywhere, and like landing.
