Tests of the European perspective rotorcraft postponed to 2021

The first flight tests of the European promising high-speed hybrid RACER rotorcraft are scheduled for the end of 2021. It is reported by Flightglobal.

The European consortium Airbus Helicopters moved from 2020 to the end of 2021 the first flight tests of the RACER rotorcraft. The reason is technical difficulties that arose during the development of the aircraft.

The concept of the RACER high-speed helicopter (Rapid And Cost-Effective Rotorcraft) was introduced in June 2017 at aviation exhibition in Le Bourget. The machine is being developed as part of the Clean Sky 2 research program. The goal of Airbus is to create a helicopter with a cruising speed of more than 400 km / h.

Rapid And Cost-Effective Rotorcraft is equipped with one rotor and two thrust tips. It is stated that the rotorcraft will be able to reach speeds of up to 220 knots (407 kilometers per hour) and fly at distances up to 740 kilometers. The cruising speed of a rotorcraft will be 190 knots.

The creators of the RACER rotorcraft claim that their aircraft, in order to save money, will be able to turn off one turboshaft engine during the flight. This will be possible after the developers install a special electric motor on the rotorcraft, which will help cope with the load of the main engine. However, to date, two main problems have not been solved: designing the main gearbox and developing a transmission that will transfer part of the power to the wing propellers. It is planned to solve these problems and start production of the gearbox and transmission before the end of 2020.

Technology tested on Rapid And Cost-Effective Rotorcraft will form the basis of the production helicopter, which is due to appear by 2030.

Well, how are the children! Without solving the problem with the propulsion, it is impossible to increase the energy intensity of the flight itself and interaction with the external environment. And most importantly, everyone is trying to convince that the parameters of effective flight efficiency have been achieved.

And Putin is to blame for this? ....

[AU Ivanov.]

Serdyukov. Serdyukov is to blame for everything.

Well, if so, then at least some benefit from the person ...

[gridasov]

And what about politics? Just the question is, if you want to solve a problem, then you need to look for a solution. And they just, as in a joke, jump for a banana and that’s it! And someone should appear to say that there are many methods to get it.

Somehow strange speed in knots. Difficulties in translation, but could indicate in miles, it will not fly across the water.

Actually, a knot, this is the speed of miles per hour.
Another thing is that the miles are different, there are "land" and "sea".

[Vladimir_2U]

In the nodes of the US, the British seem to measure the speed of the aircraft. In aircraft carrier 100 percent.

[AU Ivanov.]

Almost all of the world's civil aviation measures speed in knots and height in feet. The exception is China.

[Vladimir_2U]

The USSR is also in the nodes measured? Well, okay, why should I write this, I didn’t ask the question. Less by the way is not from you?

And just put the motors on the pushing screws, no?
The generator drive from the main engine and everything, there are no more problems, immediately and fuel economy.

[Zaurbek]

It would be so simple, would do! Apparently, something is in the way.

[gridasov]

The problem is not the drive, but the mover!

[Zaurbek]

Yes, they have a TVD shaft of all sizes.

[Amateur]

Apparently, something is in the way.

Such an engine does not fit into an airplane because midsection does not let, gives a restriction. The speaker continued the story about the aircraft, and Batitsky suddenly frowned and suddenly stopped him again with a new question:
- Well, such a large plane, and its locator does not see far? It is necessary to increase the detection range.
The speaker replied that this is a fair requirement, but in order to increase the range, it is necessary to make an antenna of a larger diameter, in addition, to put a more powerful generator, and this will also entail an increase in volume and weight. AND midsection again does not allow it. There are certain restrictions - then the plane will not go to supersonic so quickly, it will have greater losses and lower speed. Batitsky frowned even more. When it came to arming the aircraft, he made another remark:
“Why only four rockets?”
- The fact is that there are only four pylons on the plane. In order to hang the rockets under the fuselage and drown, you will need to make a special device and slightly increase the fuselage. But this again does not allow to do midsectionHe cuts us everywhere.

Then Batitsky said:
- What are you, such an illustrious design bureau, such an illustrious team, but you cannot deal with one liquid?

(V. Menitsky. "My heavenly life")

Great passage! So with the propeller and rotorcraft and helicopter. The interrelated reasons do not allow you to fly normally. So you need to change the basic principles. But for this they don’t like those, if not to say, they are ready to destroy

[Zaurbek]

We must look at those who fly .... and who solved this problem in different ways .....

[113262a]

Very original and correct idea! Respect to the bourgeoisie! The classic single-rotor scheme has a tail rotor that steals from 5 to 20% of the power of the main one. There are two screws with differential gears, which are both steering and pushing! Worthy of imitation! In Chinese, one must quickly and brazenly!

[Nikolaevich I]

And answer for the "rotorcraft"! For the illegal use of someone else's intellectual property! Only Kamov aircraft can be called rotorcraft! Historical narrative:When the Americans took up their convertiplanes, then in the USSR, too, they could not pass by "this" side! So it was ordered to create "the same thing, but with mother-of-pearl buttons" ... and it should be called in Russian ... there is nothing "great and mighty" to spoil with foreign borrowings ... after all, they managed to replace the helicopter (helicopter) with a helicopter! So it appeared rotorcraft Ka-22, and then other ... projects!

[Punisher]

They will say that KGB officers stole top-secret files with all names, past and future

[Chaldon48]

To operate a powerful electric motor, you need an even more powerful generator with it. I wonder how things are on this rotorcraft.
