US military aircraft will receive new ejection seats

In all US aircraft, except for the new F-35 Lightning II fighter jets, they will replace the ejection seats. This upgrade will be carried out to ensure the safety of pilots, writes Aviation Week.

Currently, the vast majority of US Air Force aircraft are equipped with ejection seats ACES II, developed by the American company UTC Aerospace Systems. They were developed at the start of the 1990s, and more than ten thousand of these ejection seats have now been released. They are used in F-15 Eagle, F-16 Fighting Falcon, F-22 Raptor fighters, A-10 Thunderbolt II attack aircraft and B-1B Lancer and B-2 Spirit bombers. And during that time, they saved the lives of 654 pilots. The probability of ejection from these seats - 91,4 percent.

Two companies - UTC Aerospace Systems and British Martin-Baker, which supplies chairs for F-35В fighters, intend to participate in the tender. UTC Aerospace Systems is ready to offer the military an improved ejection seat ACES 5, in which special attention is paid to safety. The chair has a headrest with neck support, which fixes the head during the ejection. The British company also upgraded their seats. They appeared switch with two positions - for ordinary pilots and those who have a body weight less than 68 kilograms. This will save the latter from injuries of the cervical spine.

will replace the ejection seats.

It would be nice if the new seats were triggered (catapulted) when they saw the Russian Aerospace Forces aircraft, or when aiming the aircraft’s armament at a civilian ... These would be what you need.

I would like to know the statistics about our chairs. There will be something to compare.

Our seats are better. As for the old seats, the overload during bailout reached 30g in them. This led to injury to various parts of the spine. Now in this direction we are ahead of the United States.
Zvezda JSC) is the leading enterprise in Russia in the field of creating integrated systems of individual life support systems for pilots and astronauts and rescuing them in the event of aircraft accidents. Among the developments of the company is a family of unique ejection systems. The ejection seat K-36 was the result of lengthy development, laboratory research and testing. Complete with protective and oxygen equipment, it is a system that surpasses all foreign analogues. The know-how accumulated as a result of the development and its implementation, along with a number of unique engineering solutions, allow this system to save the crew of the aircraft in almost the entire range of altitudes and flight speeds. In this case, the chair provides a "soft bailout", eliminating injuries.

Consider that we are not ahead of the seats either, because We sell new aircraft, S-400, etc. to anyone. The Americans and their allies, as well as the Chinese, very quickly copy all Russian know-how and immediately put them into production. For some reason, in the Russian Federation this does not work out ...

Not so simple. If it were possible to achieve the same characteristics with simple mechanical copying, then yes. But there are unique manufacturing methods that protect the eye more and which make the product itself unique.

We sell export options and they are very different from our domestic ones.

o overload during ejection reached 30g in them.

Where does the data come from? Overload on bailout 18g? when practicing bailouts at the training complex 12g.

[NN52]

Think before you write ...

To 36 DM series 2 peak 21.
On NCTL MAX 3 ... But also unpleasant ...

[Pete mitchell]

Maybe on NTL and 3, but before the training was 8g or 12, not boring once a year.

Think before you write ...

Everyone needs to think ...
1. For KM-1M seats and the like, overload during ejection depended on the mass of the pilot and the acceleration created by the squib, which led to a spread of overloads within 18-20 units. depending on the weight of the pilot with equipment.
2. With regards to K = 36DM.

The ejection chair K-36DM series 2 serves as a workplace
pilot and means of emergency escape from the aircraft;
low.
An ejection seat provides pilot rescue in a wide
range of speeds and altitudes of the aircraft, including take-off, mode
H = 0 and V = 0 and is used in combination with protective equipment
The main technical data of the chair:
- mass, kg ……………………………………………………………….… .142,5
- maximum speed of safe bailout, km / h ... ... ..1400
- minimum safe bailout speed, km / h ... ... ..75
- height range of safe bailouts, m .. .......... 0 ... 25000
- initial bailout speed, m / s ……………………… 13,6
- maximum load in the “head-pelvis” direction ……………… ..20 which also depends on the weight of the pilot in equipment.
- the duration of the maximum overload, s ............ ........ ... 0,12 ... 0,15

Further, when the powder engine is running, the overload does not exceed 15-16 units.
For K-36D-3,5 seats, additional regulation is introduced by choosing one of the three modes of operation of the energy sensor,
depending on the mass of the pilot in equipment.
At an aircraft speed of more than 850 km / h,
the established operating mode of the solid propellant rocket motor is corrected automatically
depending on overload.
3. I don’t remember the NCTL and the data in my head didn’t just arise (it seems I should train at half the working overload), in my opinion there are even different squibs, and there is something left on the 12 unit marking ...

NCTL 29-39 there were 2 squibs 8 and 12 g. What you are talking about is that there is a pneumatic throwing system, as they are called, and the characteristics are not known to me.

[NN52]

In all the regiments where I served, there was a pneumatic tossing simulator, here you are right. But it just works off the actions ... A small throw somewhere around 20-30 cm.
Compact simulator.
At the NCTL, the simulator was at the school and when they sent (as a young lieutenant) to the survival center in Khabarovsk for two weeks in 94.
The usual ass on the ass with a shovel .. no more ..
You must imagine what 12, and even 8 units are .. Let them, albeit briefly.
In Khabar, we were told about 3 units.
I don’t remember in Armavir.

two-position switch - for ordinary pilots and those with a body weight of less than 68 kilograms

If you weigh less than 68 kg - you're an unusual pilot

But I wonder how the switch eliminates injuries?

I think for the "fat men" a more powerful catapult mode is triggered than for the "slim"

In the Far East there are many such low. Japan, Korea.

[Sergey53]

Correctly. The main thing on the plane is a good ejection seat. But if we meet with ours, then nothing but him will help. Well done Yankees.

[rruvim]

"... for ordinary pilots and those with a body weight of less than 68 kg." The Chinese will be planted, or until the last Usaugend?

[NEXUS]

Nothing has been invented better than our K-36DM catapults yet ... you can eject from zero altitude and survive, which has been shown more than once.

[Thrall]

100% survival in flight simulators only ...

[Simon]

Apparently getting ready for a war with us - you won’t get away from our pilots and missiles, you can eject in time!

[win]

UTC Aerospace Systems is ready to offer the military
super advanced ejection seat ACES 5 with the letter US.
Completely open, without Velcro and sides. Fixation is provided by breathable panties that repeat the anatomical shape of the body (for those suffering from enuresis, but leading an active lifestyle).
Open half, without sides, but with a durable elastic waistband. The advantage of such seats for pilots is that the skin on the hips breathes.

[Political Department-M]

in addition to the new F-35 Lightning II fighters, they will replace ejection seats

These are supposedly not confusing ..? hehe check

[Kleber]

to date, more than ten thousand such ejection seats have already been produced. And during this time they saved the life of 654 pilots. The probability of bailout in these seats is 91,4 percent.

A non-acidic percentage of crashed planes is obtained.

[Achtaba1970]

I read about the modification of the K-36 on the Yak-38. There the bailout was carried out automatically, at least on takeoff and landing. Automation tracked a bunch of parameters and, if necessary, ejected, because the pilot does not have time to accept, you need to understand that the plane crashes and cannot be pulled out, then decide to eject, pull the ejection handles, + the response time of the ejection itself. From the article, I realized that we had practically no deaths during the bailout, and the British pilots on the “Harriers” refused such a system and practically no one could survive during the bailout on takeoff and landing.

[Ace Tambourine]

On the Yak, the rescue algorithm worked regardless of the pilot .. one of the known cases when the Yak started circling around the vertical axis, but was manageable, the system itself decided and threw the pilot out ... And the control algorithm takes into account the position of the aircraft in space, and spreads its seats along the most secure trajectory ...
I had a client, a developer and a tester of this system, we tested it on myself .. Died a month ago before the 70th anniversary ... Health was already zero ..

[NN52]

With such a nickname and such write ...
Automation worked only with a roll of 15 degrees.

Do not write nonsense, pzhl ...
On the NTL, the simulator was once a year, as well as two parachute jumps //
Sensation during exercise, like a shovel in the ass, nothing more ..

[Doliva63]

Your ass is strong, however! As far as I remember, the range of squibs was still 8 - 12. Maybe their nomenclature was wider, I don’t remember already, but in training these were put.

But the most important thing in these new ejection seats is the hole in the bottom of the seat in case of an unexpected encounter with the enemy.
