Abstract
The paper deals with a method of reduction of aerodynamic drag of a high-speed vehicle by means of active modification of the airflow with injection of light gas with high speed of sound, which can also mitigate the surface heating load. Analytical and numerical researches are carried out. An experimental model of the system of the isobaric modes implementation is created and tested in a wind tunnel for the first time. The results show power efficiency and possibility of realization of the isobaric modes of active airflow modification. An example of possible application of the isobaric modes to reduce the aerodynamic drag of a high speed vehicle is considered; it made it possible to halve the launch mass of the vehicle as compared with a vehicle with a solid propellant engine.
