Boeing and Sikorsky are working together to replace Black Hawks

Boeing and Sikorsky have expressed confidence that the technological prototype SB-1 Defiant they are creating under the program for creating a high-speed multi-role helicopter JMR (joint multi-role) of the US Army will not suffer the fate of RAH-66 Comanche, reports flightGlobal.com on October 22.

Samir Mehta, President of Sikorsky Military Systems (Samir Mehta), stated that substantial investments in prototype development prove confidence in its design and satisfaction of the requirements of the US Army if the program is completed to the end. “If we thought that the army could abandon this program, we would not invest our dollars in the project. We vote with our wallets, ”he said.

Boeing's JMR program director, Pat Donnelly, says that both companies pay far more than half of the development cost, but have not announced a specific amount.

The Sikorsky-Boeing Group is one of four competitors for winning the development of a new helicopter designed to replace the Sikorsky UH-60 Black Hawk in the 2030s. SB-1 Defian has coaxial rotors and tail pusher, this scheme will allow you to create a high-speed and maneuverable helicopter that can fly with great acceleration, perform vigorous braking and the ability to fly sideways, and also to soar down the tail section with the tail up.

The competitors are Karem Aircraft, AVX Aircraft and the band Bell Helicopter-Lockheed Martin. As expected, in 2014, the US Army will choose two winners, the first flight of the demonstrators is scheduled for 2017 year. Competitors expect the army to issue specific requirements for the 2020 helicopter area of ​​the year,

Since the beginning of the RAH-1980 Comanche helicopter, 66 billions of dollars have been spent on development since the beginning of the 7-s, and the program was canceled in 2004. The helicopter was the victim of budget cuts. Nevertheless, the Sikorsky-Boeing team is confident in the success of the new program due to the effective separation of work on the creation of individual components of the helicopter with the best use of the strengths of both developers. “This is a classic example of the fact that one plus one is not two, but three,” said Mehta.

Still switched to the Kamov scheme. But the propeller on the tail looks wild. Krlson damn

But the speed is high at minimal cost. The British were forced to create super-expensive blades with cool tips working on supersonic. But they, having set a record, rested in limiting the maximum speed of the helicopter. And the serial models did not set record blades.

And anyway, the coaxial design of the screws.
So, the future is with this scheme.

Here the scheme is most likely used for a specific task. This helicopter has increased speed performance, for this they abandoned the tail rotor. This is more likely not a helicopter in the classical sense, but rather a rotorcraft, only the wing has been transferred to the tail boom

the project looks good. let's see what happens. I don’t see the point in praising, and even less so

Trying to copy the Ka-52, at least make a transport one?

[Mikado]

the difference between the design of the ka-52 and the fact that the picture (pushing screw) is huge.

If you suffer for a long time, something will come out

Well, they will develop a sophisticated, expensive, technically complex helicopter, but it is unlikely that it will replace the "workhorse" Sikorsky UH-60 Black Hawk.

And how is it categorically more difficult? Coaxial design plus thrust per pusher propeller (if thrust will be used at all).

The logic of accessing the coaxial circuit with the pushing screw is understandable. But everything is exactly when you see her feeling that something is cn, oh stole. Since before, it was almost commercially applied only with us.

Gentlemen, comrades, the traditional scheme for all helicopters is good, but it is outdated like a dinosaur, the future for the push-and-rotor scheme, the type-Bell v-280 scheme also takes root, and no one canceled quadrocopters ...

just yesterday, half a day I was on the websites of foreign manufacturers "helicopter", they don't say that there, but they are already making and testing prototypes of non-traditional schemes of vertical vehicles, I know ours are also holding their noses in the wind, just like theirs, our equipment is expected by 18 -20 year, but we have, that is not a year, then some kind of adventure with "political economy" - to be in time ...

In place with an increase in the number of screws is an increase in the number of technical problems.
All this is a hat and not new achievements !!!
Bell V-22 Osprey is a machine that is still not considered reliable and all the problems have not been fixed for 20 years of operation !! I can vainly name five problems that will have to be solved in such machines.
Traction control, multi-directional flow control in space, vibration loads, trouble-free computer and software for such vehicles will cost as an aircraft carrier !!!

They decided to cut a high-speed spinner? I will not be amazed if this is after the Kamov and Milev renderings. Our first announced that there will be such turntables to design.

[Windbreak]

They had them in the form of flying samples long before the Kamov and Milev renderings

[kafa]

amusing machine, old circuits are already going out of bounds here and trying to combine

[Migari]

Americans did not practice helicopters with two rotors, but two Russian manufacturers of helicopter equipment, KB Kamov and Mil, and one American, Sikorsky, almost simultaneously announced the development of a helicopter with a pushing propeller. The Ka-92 with coaxial bearing and coaxial pushing propellers will It is designed to carry 30 passengers at a distance of more than 1400 km without refueling. The helicopter cruising speed will reach 450 km / h.

Information about the Mi-X1 and Ka-92 appeared at the end of 2007. And Sikorsky X2 flew in August 2008
