Study of Changes in the Aerodynamic Characteristics of the Axisymmetric Supersonic Vehicle in Case of Gas Blowing from the Lateral Surface

Abstract

We consider the flow around the axisymmetric supersonic vehicle with the use of gas jetblowingfrom the lateral surface. The blowing is made in series of points at different distances from the nose fairing. The aim of the work was to determine the changes in aerodynamic forces and the formation of the moment, when jet of gasblowingin different parts of the supersonic vehicle. The study was conducted by numerical modeling of different cases of injection. As a result, data were obtained which showed the degree of influence not only jet thrust from the jet flow, but same the impact of the redistribution of the flow by body surface on the formation of aerodynamic forces and moments.
