Perspective tiltrotor first launched engines

American perspective convertiplane V-280 Valor during ground tests for the first time launched the engines and rotated propellers. According to Breaking DefenseThese checks were considered successful. They were carried out as part of the preparation of the aircraft for the first flight, originally scheduled for September 30, but then postponed.

V-280 is being developed as part of the FVL 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 tender also involved a consortium Sikorsky / Boeing, creating a high-speed helicopter SB-1 Defiant.

During the first engine start, the promising convertiplane V-280 was securely fastened to the platform on the ground. This was done in case of a possible failure in management, in which the device could take off. In the near future, preparations will be made for the first detachment from the ground, during which Valor will also be tied to the ground.

Bell Helicopter presented the draft of the convertiplane Valor in the spring of 2013, and its ground tests began at the end of July, 2017. It is expected that this unit will be able to fly at speeds up to 519 kilometers per hour, and its combat radius will be 1,5 thousands of kilometers. The V-280 engines will be stationary: when moving from helicopter to airplane mode, only the propellers will be tilted.

The United States today is still the only country that has armed converters - V-22 Osprey, developed and produced by the Bell / Boeing consortium. In July, 2015, the five convertible plans Osprey acquired Japan. The military of this country liked such devices due to maneuverability, speed and undemanding to the landing sites.

Range and flight speed are higher. Nothing more. They cannot hang weapons on him - the design does not allow.
In Russia, a helicopter is being developed that will be able to compare with a tiltrotor in speed, but I don’t know the details.

Thank you! I read ... the essence of the convertiplane is just an attempt to get out of criticality .. I don’t know how it is possible, but the larger the screws, the more difficult .. Well, how to explain .. at the end of the blade we seem to already have supersonic speeds .. and from here aerodynamics clearly tells us that increasing the speed of the device is limited .. V device + V blades cannot be matched + it has already been proven that screw aviation (in terms of speed) has exhausted itself ... Well, for all the capabilities and technology, the device has a data limit of 500 kilometers per hour ..., all that can be pulled out of them is to improve BREA .. here the field of activity is not limited ... (by physical laws .. until the end has been eaten up) .... But the treat is cool ...

The MI 30 convertiplane was also being developed in the Soviet Union. But they considered the project unpromising. The reason is in the context of your question.

[ProkletyiPirat]

it was not developed, only the model was proposed, but "not sold"

Scientific research work is underway in Kazan; those who have allocated money for such work do not speak, but it’s clear.

the model on the Roller ... Working ... But it moves only in a helicopter mode ... It looks like a B-12 (MI-12) helicopter of the late 60s ...
It was created in duplicate for transporting missiles in the Strategic Missile Forces, BSP (combat launching positions) of which were often near the devil on the sandpit, off-road ...
So - nothing new, again, all of the Soviet backlog ...

If at a new technical level they put it into production (someday), it will be nice. But if it remains a model, our analytical journalists will write that the branch is deadlock and in general they are falling.)

Well so ... With the B-12 (Mi-12) it actually happened ... The most powerful helicopter ... But they produced two pieces - and that’s all ... I outstripped the time in my capabilities ...
In fact, it would be possible to develop something further on its basis ...

[ProkletyiPirat]

he was not ahead of time, he was just in time, just later there was no need to transport elements of missiles.

Something glider and tail feathers on a mattress wunderwafle looks like! Maybe the Tatars brothers designed them ?!))))

[Thunderbolt]

Speed ​​gives range. Therefore, all the advantages of flying in an airplane are used.
And helicopter pluses make it undemanding to the landing site (after all, they don’t need a strip, but only a landing area), they can act from ships --- it means landing can operate to a greater depth of the mainland, and on land they can be based further from the front line.

[Berber]

The dimensions of the screws dictate the size of the convertiplane. Accordingly, the carrying capacity. The optimal size gives minor advantages. For example, on the same MI 30, the size of the screws is 11m. 2 * 11 + some tolerances = 22+ represent the colossus.

Osprey (fuselage length - 17,48 m;
wingspan at the ends of the propeller blades - 25,78 m;
length with folded blades - 19,23 m, payload mass - 5445 kg, combat radius - 690 km) in comparison with Sea Knight (length including blades - 25,70 m, payload - 3 975 kg, combat radius - 300 km).

Who can explain why tiltrotopters are better than conventional helicopters? .. Besides speed.

Explain? With pleasure. See: higher speed at the same engine power, therefore, range and other indicators like flight altitude, etc. just increase. If it were possible to reduce the engine power by an order of magnitude, then the range would increase by another order of magnitude. It’s true that the name of this tiltrotor design is “promising”, the language does not turn. They simply simplified the design because their previous version of the Osprey V-22 did not withstand any criticism for reliability. So the presented device is better to call not promising but simplified, so it will be more accurate. It is still difficult to fully describe all the advantages of such a new technology, just the practice of use is not enough, its shock versions are just beginning to appear, still ahead.

[Muvka]

Is there one engine?

[PROXOR]

Yes, nothing. YES, he can fly upright and quickly deliver a platoon of fighters, but what's the point. When landing, he is forced to slow down in the sky. And plus, he will not be able to go in helicopter mode at an altitude of 20-30 meters because this thing has no maneuverability.

[fa2998]

You yourself answered your own question. It seemed that with reliable helicopters, mankind is still building planes. A rare helicopter accelerates more than 300-350 km / h. And the plane needs a half meter and two kilometers long, but they build it, the speed justifies the costs.
And what about us? Either we don’t need it, or we draw beautiful pictures. Then we will drive.

Why are tiltrotopes better than conventional helicopters?

Longer range due to more efficient use of aerodynamic forces.
In general, convertiplanes have one minus, they are less effective in hover mode, which imposes restrictions on their use as a replacement for attack helicopters. (Attack helicopters (Mi-28, Ka-52) use the terrain better for jumping out due to obstacles) On the other hand, tiltrotor can carry more cargo over a long range at the same fuel consumption, which makes them more efficient compared to transport helicopters.

And here you need to pay attention to the experience of the USSR / USA, the first fought in Afghanistan where many mountains and helicopters used them to protect. the second mainly fought from the sea where there is nowhere to hide and where large distances. Hence two different approaches, and not one of them is “truly true”.

[crazyrom]

In addition to speed - nothing, but the whole struggle just for speed and goes. Well, maybe a little more economical at speed, since the tiltrotor has wings that create lifting force, which means you need less power on the screws.

[Purishkevich]

I hope it will break like the previous ones

[Mountain shooter]

A tiltrotor is an under-airplane and a non-helicopter. The US enthusiasm for expensive "toys" of very dubious combat stability - from the hegemonic point of view - is understandable. Everything is possible for him, including immense spending. Only times are changing ... A Sikorsky high-speed helicopter looks much more promising.

There is another version: That the plane, that the helicopter - just unfinished or not full konvertoplan. The universality of the devices causes a decrease in certain characteristics, but other, previously unknown and not supposed new advantages appear. And further: "expensive "toys" of very dubious combat stability"- I agree about the cost, another matter is the shock version is only supposed to be released where to hang up the weapon - you can always find a place, you just need to want it.

--------------------------
Professor, an aircraft is not a skimmer, it must first be tested. The United States has extensive experience in creating such machines, a large selection of engines and other stuffing, so they quickly created the next generation tiltrotor. So there is nothing unusual in this news.

Nothing is better, because the US military complains that Osprey often needs to be repaired and it is better to have one more backup board to carry out a combat mission. Unreliable technique.

Can be improved and simplified with eyes closed.

By the way, apparently, the mechanism for turning the screws is retouched on the video.

[APASUS]

So learn to advertise your brainchild with the Americans! It’s just the first launch of the engine and an article on VO, I’m not talking about what will be in the Western media.
There may still be tests for 5 years, but the advertising contract has already begun!
