ABSTRAKT

Presented are the results of experimental investigation of the jet flow gas dynamic effect in order to control the thrust vector and to reduce the drag of the vehicle. The vehicle has a flat nozzle with an external expansion wall, being the part of the fuselage. The gas dynamic control method, based on the injection of additional air through the perforation in the expansion wall, is considered. The conclusions about the efficiency of gas dynamic control by means of various methods of additional air injection are drawn according to the weight tests and measured pressure distributions.
