The newest American convertiplane V-280 Valor flew in an airplane

Promising American convertible glider V-280 Valor, developed by Bell Helicopter, 15 on May 2018 of the year made its first flight in aircraft mode, reports "nplus1" with reference to Defense News. During these tests, the aircraft developed speed in 190 nodes (about 352 kilometers per hour).

Details about the tests were not disclosed. Probably, the experts checked the transit flight mode during the transition from the “helicopter” configuration to the “aircraft” configuration and back. The performance of the onboard equipment and propeller turning mechanisms was also evaluated.

In total, V-280 has spent 27 hours in the air so far. The convertoplane has already passed ground tests, made several flights in helicopter mode, including with a slight inclination of the propellers. In addition, experts checked the work of the onboard equipment of the device.

The V-280 is being developed as part of a JMR tender as a new army transport aircraft designed for the rapid transfer of fighters and cargo over long distances. According to the requirements of the military, such a device must be capable of vertical takeoff and landing.

The machine is certainly interesting. But it does not inspire confidence. Painful mechanisms are painful. And sensitive to pollution. And these are possible breakdowns. Often with these devices the stories happen

[YELLOWSTONE]

where is it written about?

[maxim947]

Yes, an interesting contraption, but very expensive and fuel eats unmeasured.

[YELLOWSTONE]

and where is it written about?

[maxim947]

In Karaganda

[YELLOWSTONE]

there is also not written

[maxim947]

The cost of the dispute is more than 112 million (according to other sources 68 million), Valor will be even more expensive, the cost of AH-64 Apache - about 52 million dollars, and this despite the fact that combat helicopters are usually always more expensive and an order of magnitude. Regarding fuel consumption, the consumption during vertical movement is quite large. And use the search.

[maxim947]

Osprey:
practical range - 2627 km (without refueling);
with vertical take-off - 2225 km;
during take-off with a short take-off - 3340 km; - difference in ton.
With a mass of 15 tons, the consumption is in the region of 2,6 t / h, at the glutton MI-26 (on ancient engines) with an empty mass under 30 tons. consumption of 3,1 tons. In my opinion, the figures are not in favor of the first.

[YELLOWSTONE]

you can write about the cost
about fuel consumption and how else if the helicopter is not moving like that?
how far during these tonnes will both fly?

[maxim947]

how far during these tonnes will both fly?

the tiltrotor will fly further, and the same MI-26 cargo will take 3 times more.
About:

you can write about the cost

- search for yourself, and prove to yourself, the topic is closed.

[YELLOWSTONE]

further and three times faster

[Yodzakura]

consumption is large enough
In the usa print money for them it is not unprofitable

[Sergey ippon]

the main thing is to start production - then it’s easier to finalize. than do nothing.

[Nix1986]

Fly on balls, like blame the fluff, which is easier.

[cats]

Such difficulties, and the speed is 352 km .. Was it worth it? In my opinion, an ordinary turntable
so much can.

[YELLOWSTONE]

below they write that for example 500 although more than 600

[Yodzakura]

Oh well, how many years flies?
At 280 only vents rise and not the whole engines

Will fall as famously as the Hornet and Osprey

Not a fact ... they already have their second serial ... Children's illnesses are basically taken into account ... And everyone falls to fall ...

[impostor]

Of course. But I like their envelopes from star landing more - they sit on ramjets in the midst of paratroopers, while only a light breeze and not a single charred carcass

How did you like the fact that in the film the race of people who mastered interstellar galactic flights lost all tanks, helicopters, night-vision devices, thermal imagers and small-sized walkie-talkies? )))) And people still have mortars, mines, multiple launch rocket systems and nuclear missiles somewhere)))))

[Dead duck]

More goals, good and different!
Your ardently loving, air defense

[rotmistr60]

At one time, we turned down convertiplanes, and the Americans clung to it and continued to develop. But that is their business.

[YELLOWSTONE]

it was also their business

[KVU-NSVD]

Beautiful machines, but expensive and in terms of efficiency and price, are massively available only with an American money machine. And their predecessors did not differ in reliability.

[NN52]

But at the speed declared by amers for him at 500 ... in airplane mode .. Not a bad thing for transporting people, etc. ... And it seems like a strike version will also be ...
About reliability ... everything breaks down .. And for everyone.

[net0103net]

I wonder what will happen if one of the screws stops? )

[betta]

So what? Forced fall, only.

[net0103net]

Very crooked inconvenient drop for landing and bailout) So they need it. They built the BMP - the mass grave of the infantry.

[NN52]

There was an article already in VO, sort of .. If one fails, then it seems that rotation is transmitted through the shaft from the working engine to the failed one, I don’t remember exactly ... If interested, look ..

[net0103net]

Yes, I also read, it was funny) .. But it's not about the engine, but about the screw. If you are a good engineer, then you see the same picture now as I do - enchanting freaks in the air and the inability to escape)) The supporting wing also holds many surprises, for example, the failure of the entire program, you just have to get into the fire of air defense. Well, the high cost of course, especially during operation and improvements that will never end, is worth this tin can go on an unsuccessful assignment. In fact - this is the same kinolap as the F-35, but not so funny, but also instructive.

[YELLOWSTONE]

what if the chinook and his ilk like the CH-46? these screws are more reliable

[Topgun]

saved a lot of "autorotation" of lives?
in my memory, not a single one, only in a Soviet film about her I saw 2 helicopter survivors who survived, and so no helicopter crash, so everyone died ...
and the tiltrotter range (combat radius) (due to the economy of the “airplane” flight) has many times more + speed (almost 2 times) more ...

[gridasov]

A very interesting aspect is that the propeller blades should not rotate towards the body. To a greater extent, this applies to the left mover

Yah? And in which direction will they rotate?

[gridasov]

You remember the physics. The propeller must rotate when viewed from the front, clockwise. Why ?!

[prodi]

but in fact, why?

[gridasov]

Just as in the bearing the balls not only rotate each by themselves, but all together they move together. That is, there are break-in moments of the entire series and individual parts. Therefore, the rotation of the blades form the same circular stream. Therefore, recalling the rule of the left hand, it is clear that the entire flow should, like magnetic forces, move backward, forming a thrust. Otherwise, the outflow flow to the blades will counteract this circumferential air flow, and with increasing rotation speed this opposition will only increase. Pilots often notice a sharp increase on the control levers. In general, there are a lot of such nuances and all of them need to be harmonized. It was precisely about this that Tesla said that it is necessary to use positive extremes at all stages of the physical process. Everything is obvious if we consider banal simple, seemingly, magnetic force interactions

[gridasov]

By the way, the durability and load resistance of bearings can be increased by orders of magnitude if, in accordance with the rules of physics, it is changed

[prodi]

I see NO obstacles to create normal traction in the "opposite" rotating screw

[gridasov]

Too subjective. At the same time, the increase in the rotation speed of not only the propeller blades, but also of the turbines has a negative effect, and ultimately all the consequences

[farcop]

Quote: gridasov

Stop. You said you should not rotate towards the body. Not in front, not in back, not by the rule of the gimlet and others like him. must not rotate towards the housing.

[gridasov]

Do not cling to words. I can only apologize for having incomprehensibly expressed myself. The essence of the process is still obvious.

What an apology, explained and will be.

[gridasov]

This is only one of the elements of the process that makes it possible to reasonably speak not only about the inefficiency of propellers and propellers, but also that new devices in the form of a mover are orders of magnitude more efficient and have a great future in application

[farcop]

When will be. In the meantime, there is what it is.

[Nix1986]

But is his TTX in the public domain ?! Compare with osprey on the main parameters.

[Hole puncher]

The tests have just begun, there are no confirmed characteristics yet.

[Nix1986]

Most interesting is its carrying capacity and speed compared with the same hawk. How much does a sheepskin stand out. Judging by the size, the carrying capacity is not much higher than the hawk, the main thing is the speed and radius of action.

[DimerVladimer]

Handsome men!

Vertical take-off / landing and speed above helicopter - as required.

That is, the payload, combat radius, maintainability, cost and resistance to damaging factors do not give a damn?

[Mih1974]

I wrote earlier, but I think it is necessary to repeat - let's all think "why the hell did such freaks surrender?" That is - why it is necessary to refuse from tested and brought to almost ideal helicopters (different brands and schemes) for the sake of such a perversion. In theory, a decrease in flight time by the same distance, hmm, I agree, but "WHY?" Well, let's suppose - so that the enemy does not have time to pinpoint us like helicopters and react (shoot down). Hmm, it seems logical, but let’s say - who is this “cool” one who shoots down your helicopters but cannot convertoplane? Here then the apologists of this "miracle" fall into a stupor . The fact is that the development of modern technology is so complete that a helicopter and a tiltrotor are all clearly visible. The reaction rate of air defense systems - is minimized, almost to "immediately", the range of missiles is generally prohibitively far.
That is - a technically equipped enemy will fill up this crap as they don’t do FIGs, the "poits" will not be able to shoot down a helicopter, or THIS! And that means - all these "achievements, which have no analogues in the World" - a simple theft of money, which has absolutely no real basis.

[YELLOWSTONE]

just to fill up the Papuans at kotoryz bow and arrows you need to go back to the berdanks and three rounds each, and then a Chinese with a Kalash from the bushes or an American and other European with M-16

[Mih1974]

Mock, but in essence - why complicate the cost and reduce security? I am not a retrograde and do not "demand to return to the huts and caves", but any "advance" should be logical and reasonable. Remember the "great idea" "concord" - but time has shown that it is either too early or not at all in this sense. . Yes, from a technical point of view - it’s very interesting and “advanced”, but I don’t see the point (personally).

[YELLOWSTONE]

Remember the Tu-160? then be able to run when you can just walk? even turtles know the answer to this question

[Aqr009]

A couple of pluses are still striking:
1. the combat radius is much larger than that of a helicopter, which means that ships can remain in neutral waters (this pepelats is used mainly by ILC);
2. The speed is twice as high as that of a helicopter, which means help for evacuation will arrive twice as fast (although it would still be more practical to use an ultra-fast helicopter).

[Topgun]

what is the "distance" too? pull up the materiel a little ...
just the distance (combat radius) of the convertiplanes is several times (once again TIMES) greater than that of the helicopters (there was even an operation against a drug cartel in South America where specialists from the USA flew on convertible planes crossed the entire Caribbean region without landing and landed in the jungle (like Colombia , if you need, see documentaries about Osprey for sure)
It is because of the combat radius that they are made (speed is also important but the main profit in range), after the US embassy was seized in Iran and the CIA could not evacuate it (they even prepared hercules with rocket engines for a special operation but the plane crashed) the military had such a request and today it is possible to implement it ...

[Chicha squad]

But how did the V-22 show itself? They were also used in combat conditions.
