TsAGI performs air-flow tests on future multi-purpose light aircraft
21 June 2013
The experiment showed that at maximum lift the flow breakdown starts at the wing root and gradually develops in scope. Moreover, in post-stall modes the non-breakdown nature of the flow at the extremities of the wing is retained at the location of the ailerons, which provides roll control in all flight modes. In general, the tests demonstrated the favorable nature of the flow in a wide range of angles of attack and slip, including critical values.
This work builds on a range of experimental tests on the aerodynamic features of the multi-purpose light aircraft, begun in 2012.
The data received will be used to make recommendations on the development of local aerodynamics with the aim of further improving the multi-purpose light aircraft. It is further planned to conduct experiments on the effect of propellers on the aerodynamics, stability and handling of the multi-purpose light aircraft with various tail configurations.The technological platform available for multi-purpose light aircraft with increased deployment possibilities was developed by experts from the Zhukovsky Central Aerohydrodynamics Institute (TsAGI). The platform can be used to create future 9, 13 and
