American high-speed helicopter SB-1 Defiant redesigned

The multipurpose high-speed helicopter SB> 1 Defiant has received an updated version, which will be offered to the US Army tender. According to Breaking Defense, the new version was named Defiant-X.

A consortium of Sikorsky and Boeing has made significant changes to the design of the promising helicopter. The updated version is called Defiant-X (X stands for high readiness) and will participate in the US Army tender.

As the developers explained, the redesigned helicopter received a new chassis. The previous scheme with a tricycle landing gear with the placement of two struts in the front and a steering rack in the tail was replaced by two struts in the aft and the steering rack in the bow. The nose section has become more pointed, a fairing has appeared in the tail section. In addition, the helicopter received an electro-remote control system with the ability to switch the machine to unmanned mode.

Changes have been made to the exhaust system, which exactly is not disclosed, visually the system has lost the exhaust nozzles of the exhaust device, which were previously located under the rotors in the tail section.

All the changes made should significantly improve the controllability and stability of the helicopter.

The multipurpose high-speed helicopter Defiant-X (SB> 1 Defiant) is created on a competitive basis as part of the US Army program to create a family of promising army helicopters. aviation... Development has been underway since 2015. It uses the developments obtained during the development and testing of demonstrators of high-speed X-2 and S-97 Raider helicopters. The helicopter weighs 13,6 tons. It will be able to reach speeds of up to 250 knots (463 km / h) and carry 12 troops. The machine is built on a coaxial scheme with a tail pusher rotor.

Multipurpose high-speed helicopter Defiant-X

The Yankees create new techniques, this is a normal process.

The Yankees create a new technique, this ...

What, someone is creating an old technique?

Let's not talk about misunderstandings like Ukrainians.

All normal design bureaus create a new technique.
And this is natural.

What, someone is creating an old technique?

Admittedly, they create not just a new, but really NEW FORMS.
I will not say that everything is smooth for them, everything is working out, but this is a search, a movement forward.

[Alex777]

Wangyu: when this helicopter is completed, it turns out that it is more expensive than a tiltrotor.

[rocket757]

Ha, this is very likely.
Although, the firm has to pour over development costs, in one way or another .... this is reality.

[Alex777]

In the States, this probability is already being discussed.
They can also close the project without finishing the series.

[rocket757]

It happens, BUT, too often to wrap new items back, to send the case to the back burner, but when not later, it can become a diagnosis and the eve of a disaster!
However, this is their business. Let them figure it out themselves.

[OgnennyiKotik]

All contractors' expenses under the state program are paid. They are only happy to participate in such programs, a lot of groundwork goes into civilian life. For example, the Boeing 747 Jumbo Jet is a converted truck for the Galaxy C-5 program. They are sad from the fact that the project was closed, but for the money they are only in +.
Sikorsky's X2 series participates in 3 multipurpose, shock, shock reconnaissance programs. Something has to go into series.
He can win in all programs. Three types of helicopters built on one platform will greatly reduce the cost of purchase, facilitate and reduce the cost of operation.

[lucul]

Changes have been made to the exhaust system, which exactly is not disclosed, visually the system has lost the exhaust nozzles of the exhaust device, which were previously located under the rotors in the tail section.

But this is serious.

The new system is reminiscent of the developments on the RAH-66 Comanche, which is totally stealth, on which it "got burned"

[Mountain shooter]

Serious car. Fast and quite lifting. True, the speed is not radically high. A 50% increase is relatively high. But an absolute increase of 150 km / h - perhaps the efficiency will increase. For air defense it is all the same ... And MANPADS, and all sorts of "Shilki-Tunguska-Pantsiri" will not miss.

For air defense it is all the same ... And MANPADS, and all sorts of "Shilki - Tunguska - Panziri" will not miss.

Like, they will miss an aircraft developing 700 km / h ... 460 m / h is the cruising speed of the An-26, for example. But rotorcraft fly lower than aircraft and 400+ km / h is a decrease in the time spent in the field of view of the same MANPADS, and the MZA too. So, good speed and light air defense, it will make life quite difficult for itself.

[Mountain shooter]

These are the flight speeds of aircraft over the WWII battlefield. They will, do not hesitate. And our attack aircraft flew at low level, with comparable speeds. But they carried serious armor, and did not fall from the rifleman.

In the X series, in addition to this transport, there will be shock and reconnaissance-shock versions.
Armor is needed when using unguided weapons, of which they only have machine guns. All tactics of use imply being in the affected area of ​​a possible air defense for tens of seconds or not entering it at all.

[Magog_]

This is a transport, compare it with the Mi-8, Huey, Puma and the like.

So compare. Have you seen a lot of coaxial helicopter "transporters"? Is record speed really so important to accomplish troop-transfer missions? Unless, of course, these are some specific special operations. But we are talking about an army transport helicopter. Sorry, as far as you can understand the specifics of army aviation, in this case, the transport component is important, i.e. "I took more - moved further", which is more difficult to achieve in a coaxial scheme compared to the usual one. Americans, as always, will first try to do something (a lot of money!), And then they will think ...

If you do not know what the Ka-29 and Ka-32 are, then it is too early for you to talk about aviation.
The same applies to the epithet "record" in relation to 450 km / h.

AZAZAZAZ, Americans are fools, well, stupid people, some smart Russians create transports at a speed of 250 km / h, but we will transport more, but we will keep the old format, OU, the Americans got the speed! Almost 2 times more! 2 times! and that means the delivery time will also be reduced by 2 times, which means that the speed and capabilities are increased! And let us trample on MI-8 or MI-17) well, well)

[Magog_]

I see some snotty guys gathered here: "got the speed - twice as fast!"

[hydro]

Look at the video, in relation to other turntables - this is progress, if you are offended for the useless Russian industry, which cannot yet provide an analogue or better quality vert, then I'm sorry for you! And the Mi-8 is an old age that is losing ground. Yes, we got speed, but we got maneuverability, the concept remained, this is a good helicopter that will quickly deliver the group to perform combat and other tasks! We still have a layout, no vert! Ka-92 is generally civilian))))

[Magog_]

For civilian purposes - no objection: some kind of business jet in helicopter performance is quite suitable. In the military version, the parameters of carrying capacity, range, survivability, volume of transportation, etc. are important. Speed ​​comes last. The transported troopers must have the maximum possible supply of weapons and supplies - otherwise they are not troops, but tourists. Landing army helicopters have clearly defined missions. This is what it would be worthwhile for clever Americans to first inquire before getting down to business ... The apparatus under discussion is interesting in itself, but then, apparently, one should first understand for what purposes it is being made. Precisely for army transport aircraft?

[hydro]

Maybe they can be as a drummer and as a reconnaissance officer, but they apparently rely on a transport worker, such a quick response, let's see! I hope we will find an analogue and usability for this device, the speed is also a plus and a good one

[Magog_]

When designing (there is such a task area), all the "pluses" and "minuses" are taken into account. In the pursuit of speed, other significant "pluses" are inevitably lost, and you get an unnecessary item or try to repurpose the product on the fly, which in fact means non-fulfillment of the terms of reference.

[garri-lin]

Why were the propeller blades originally flexible? Although it was technologically much easier to make them rigid? It's not about inertia, but about the loads on the blade. And the higher the speed, the higher the difference in load at any given time, per revolution. A rigid structure resists such constant loads worse than a flexible one. Therefore, it needs to be made much stronger.

Blade inertia? Or the inertia of the entire aircraft? Or the inertia of air masses? Who would talk about porridge.

Of course, the "inertia of the entire aircraft", due to which the blades bend more during maneuvering than during straight flight and there is a danger of collision - the scourge of the coaxial scheme, forcing the NVPs to be greatly spread in height. For a person who knows physics, it is very easy to understand what I mean by context. There is no such danger on the SB-1, as the blades are short, stiff and do not appear to have a horizontal hinge. You should not consider yourself the smartest, but the designers of "Sikorsky" -. They know this better than you.

[garri-lin]

As if the blades were originally made flexible so that they could more easily transfer loads. They did not resist the load, but rather succumbed to it. This is elementary materials science. A short and stiff blade should be much stronger to cope with the load. I will not say anything about the horizontal hinge. The transmission of vibration to the gearbox will also be enormous. I do not consider myself the smartest. I just see inadequate solutions of others. For a speedboat, the optimal scheme of a bicopter with a blade in an annular channel. Something similar to what flew in the movie Avatar. With push propeller and aerodynamic fuselage. The midship is larger. The only problem.

I was interested in the success of the Russian Helicopters holding and what it can offer. Here's what I found:

The Ka-92 is a project of a high-speed helicopter with coaxial rotors, developed by KB Kamov as a competitor to the model proposed by KB Mil. The project was developed by order of the government of the Russian Federation. The project cost is estimated at $ 1,3 billion ...The concept design and some technical specifications were submitted at the professional exhibition HeliRussia-2009 at Crocus Expo ... In 2015, control over the development of the Mi-X1 and Ka-92 models was transferred from the Ministry of Industry and Trade to the Ministry of Defense, due to a reduction in government funding and an increase in operating costs. According to the general of the Russian Air Force, the first flights of prototypes will take place in 2018, and by 2022 serial production of models will be established ...
