To replace the Yak-40: the plane with the "black wing" has passed flight tests

July 4 2019 11

Aircraft with an all-composite wing, created by engineers SibNIA them. S.A. Chaplygin on the basis of the "flying laboratory Yak-40", successfully passed his first flight tests. The prototype was equipped with two engines (the Yak-40 has three) and an integral wing made of composite materials made at the institute. Due to the natural black color, the wing is often called “black”, thus clarifying technology its production.

According to the director of the aforementioned university, Vladimir Barsuk, the tests fully met the expectations of the designers. The functionary also added that after several flights of a 19-seater turbojet aircraft, all work was handed over to the Ministry of Industry and Trade and that’s where the participation of SibNIA in the project is over.

According to the results obtained during the tests, the new aircraft consumes half the fuel and can reach a speed of almost 35% higher than that of its "eminent" predecessor. The entire composite wing installed on the prototype allowed the aircraft to develop a cruising speed of 700 km / h. In the Yak-40, this figure is 500 km / h. In addition, as mentioned above, the tested prototype received two engines instead of three, which allowed to reduce fuel consumption from 1150 kg / h to 560-590 kg / h.

Recall that the Yak-40 is the world's first passenger turbojet aircraft, which was developed by the USSR in 1960. The device belongs to small aviation and is intended for operation by local airlines.

development is good and necessary, so the government will try to ruin and cut off funding.

  everything itself will die out, as always. Where are the electronics, bearings ... ???

The prototype was equipped with two engines - that's more about the engines, and then as always probably.

Whose wing materials? Something is silent in the article. Bought over the hill again? And the number of orders for this plane? (whose source code was completed 50 years ago)

  Sergey, it’s very, very early to talk about orders, in essence - this is a new plane and its testing has just begun. The production of hydrocarbon fibers in Russia is growing at a staggering rate. It is planned that this year it will exceed 1,5 thousand tons per year, and by 2020 they will bring it to 5 thousand tons, and 2 more plants are under construction. It is discouraging that more than half of the high-tech raw materials produced go abroad. Most likely, nobody needs such materials from us.

    Innings. When foreign gentlemen begin to develop something, they usually write right away: the estimated number of orders is 500 units, contracts for 260 units have been concluded. For it is a sign of seriousness. For example, recently announced the beginning of the development of the Japanese analogue of M ... and Superjet.

To replace the Yak-40, came the Yak-40 with a new wing and two engines. Why with a new wing? Aluminum plants were given to the Anglo-Saxons.

  And what is the minus? After all, they wrote the bitter truth.

A good article, but there is a serious factual error - the Yak-40 is the world's first turbojet aircraft for local airlines, that is, the first in this class, and not the first passenger in general. Before him there were already de Havilland Comet (the first in the world) and Tu-104 (the first in the USSR). And in 1960 it was not developed, but only set the task to develop. Finished development in the 64th, and the first flight was in the 66th.

I wonder what kind of Comet and Tu-104 aircraft were then. If the Yak-40 was the first). Not, well, at least they would take an interest in history before you harp an article.

Well done, it’s small matter: to find carbon for serial production, and, as you know, it is not even for the promising MS-21.
