In May 2015 specialists of the Central Aerohydrodynamic Institute (TsAGI) have completed the first stage of a project related to studying a model of a next-generation short-haul airliner. This aircraft is being developed by TsAGI under the Federal Target Program “Development of civil aircraft for 2002–2010 and the period until 2015”. The model was tested in the institute’s trans-sonic wind tunnel, TsAGI’s press-service reports.
«The next-generation aircraft has no analogues in the world; it is distinguished by two major innovations.
The first innovation introduced by TsAGI’s specialists is a low-sweep wing, which ensures laminar flow with no random velocity and pressure fluctuations on the surface, and significantly reduces aircraft drag. The use of state-of-the-art wing airfoils allows keeping the same speed as that of predecessors — 830-850 km/h.
The second distinguishing feature of the new aircraft is the placement of the engines above the trailing edge of the wing. The scientists chose this configuration to reduce the noise from the aircraft flying over areas adjacent to airports. This environmental requirement is constantly becoming stricter and it is becoming one of the major criteria for the development of advanced aircraft.
