This paper presents the results of wind-tunnel investigations of a light convertible aircraft scale model. Tests were carried out in TsAGI low speed wind tunnel. As part of the test, the slipstream effect of running propellers was investigated. Propellers were driven by power plant simulators – strain gauge electric motors.rnThe total aerodynamic characteristics of the model in main flight configurations are obtained. The effectiveness of flaps and flight control surfaces (elevator, rudder, ailerons, spoilers) are determined. The influence of empennage options on longitudinal stability is investigated. The influence of an external cryogenic fuel tank on the scale model is considered. The slipstream effect of propellers on model aerodynamic characteristics is shown.rn
