Russian developers have suspended the creation of an aircraft with a reverse wing

The Russian design office “Modern Aviation Technologies” suspended the development of the prospective training aircraft SR-10. As reported by Mil.Press Military, the Russian authorities have not yet allocated the funds necessary to start the serial production of an airplane with a swept wing.

CP-10 is developed in a normal aerodynamic scheme with a single turbojet engine. The first aircraft will be equipped with Ukrainian AI-25TL engines, which will then be replaced by Russian AI-55I engines. The maximum take-off mass of the CP-10 will be 2.7 tons. The aircraft has a wing with a swept sweep of ten degrees.

The wing with a reverse sweep has several advantages over the conventional wing. Firstly, it allows to significantly improve the maneuverability of the aircraft. Secondly, it somewhat reduces the radar visibility of the aircraft. Thirdly, such a wing improves aerodynamic characteristics of the aircraft.

Finally, the swept wing significantly simplifies the control of the aircraft at ultra-low flight speeds. In this case, the wing in flight is experiencing substantially greater loads than the conventional wing. It is this deficiency that makes it much more difficult to develop aircraft with a swept wing.

According to the project, the CP-10 will be able to reach speeds of up to 900 kilometers per hour and fly to a distance of up to 1,5 thousand kilometers. The aircraft will be able to perform all aerobatics with a maximum overload from plus ten to minus eight units. CP-10 performed the first two flights on December 25, 2015.

In 2016 it was reported that the Ministry of Defense of Russia supported the project for the development of the CP-10 and planned to conduct state joint tests for 2017. These checks have not yet taken place. In 2017, it became known that the Russian Air Force will expect to receive the first shipment of CP-10 training aircraft by the end of 2018, which will be used on a par with the Yak-152 turboprops and the Yak-130 jet aircraft.

Test pilot Viktor Korolev told Mil.Press Military that the funds for mass production of the aircraft have not been singled out yet. In “Modern aviation technologies” this information was confirmed without specifying whether the financing of the project will be allocated and when this can happen.

According to the Queen, by now he has performed 85 test flights on the CP-10; The car proved to be stable on all flight modes. The plane was also tested with a “corkscrew”. In the event that project funding is allocated, the production of the CP-10 will be carried out at Smolensk Aviation Plant. The new CP-10 will be able to replace the obsolete L-39 Albatros of Czech production.

Currently, the Russian Air Force has about 150 L-39 training aircraft delivered to the army since the 1980s. These aircraft are used for advanced training of pilots, as well as for maintaining pilots flight skills.
