TsAGI reported on the work of the prospective short-haul aircraft – Air Transport Observer

Scientists Central hydrodynamic Institute in May completed the first phase of research a promising short-haul aircraft model, according to TsAGI. To date, conducted tests in the transonic wind tunnel of the Institute. They “confirmed the estimates in terms of speed and efficiency. It allows you to recommend this arrangement for deeper technical work domestic aircraft design offices,” – said the head of the department of aerodynamics perspective layouts civil aircraft TSAGI Ivan Chernyshev.

Sun a new generation is being developed within the framework of the federal target program (FTP) “Development of Civil Aviation in 2002-2010. and for the period up to 2015″. As highlighted in the TsAGI model for today “has no analogues in the world.” Its main distinguishing feature is called the position of the engine on the trailing edge of the wing, giving the car several advantages.

First, it will reduce the level of noise from flying aircraft. In particular, “the new arrangement, the noise from the fans of the power plant is the main source of the sound is reflected wings up before reaching the ground,” – said the institute. Secondly, this solution allows to establish more efficient engines with a larger diameter. Third, it minimizes the risk of foreign objects from the runway to the air intakes. Finally, the top position of the engine makes it possible to shorten the landing gear and thereby facilitate the design.

Sun, developed by specialists of TsAGI, also has a small wing of sweep. According to its creators, it allows laminar flow, in which “there is no random velocity fluctuations and pressure on the surface and significantly reduces the resistance of the aircraft.” Application of modern profiles allowed “to maintain the same speed as that of the predecessors – 830-850 km / h.” The additional features of the new aircraft are not specified.

It should be noted that the Japanese company Honda Motor Co. is already preparing for the certification of ultra-fast seven-seater business jet HondaJet, which the engines as well as in aircraft from TsAGI, raised above the wings and biased toward the rear fuselage. As explained by The Wall Street Journal, is a design decision led to the mixing of two air streams coming over the wing and under the engine, and as a result – a significant reduction in drag. According to the developers, HondaJet is 17% more economical than its competitors. The first deliveries of the Japanese aircraft are scheduled for mid-2015 г.

The scheme with the installation of the engine above the wing used consortium created by the German company Vereinigte Flugtechnische Werke (VFW) and the company Fokker. However, they have designed the plane VFW-614 first flew in 1971, considered a failure, and the program turned off.

FTP, in which developed advanced domestic aircraft “aims to address the competitiveness of the civil sector of the aviation industry in the domestic and international markets of civil aviation equipment. Group events” advanced aircraft technology “involves the creation of globally competitive family of civilian aircraft, to be commissioned in 2012- 2015., “- the document says.
