FIELD: aeronautical engineering; rocketry and space engineering; technology of control of flow around flying vehicle. ^ SUBSTANCE: proposed method consists in delivery of gas to incoming flow in front of nose section of flying vehicle. Density of this gas is lesser than density of medium; gas is fed to points of aerodynamic drag of flying vehicle where porous coat is formed; pores of this coat are open to surface; scale of these pores is lesser than that of vortex generation. Gas is delivered at periodicity of generation of turbulent vortices to turbulence generation zone at phase shifted by 45-135 degrees. In realization of this method coat may be formed at points where shock wave is formed. It is good practice to feed gas to porous coat from reservoir containing sorbent separating gas till gas desorption temperature has been attained. Gas is mainly fed to upper edge of wing. It is good practice to make coats from catalytically active heat-accumulating material and to realize endothermic process during passage of gas through it. Front surfaces of wings and nose sections of flying vehicles may be covered with coats of low electron emission energy from the following series: barium oxide, titanium carbide, zinc oxide, copper oxide rare-earth metal oxide and n-semiconductors. ^ EFFECT: possibility of changing aerodynamic properties in turbulence generation zone. ^ 16 cl |
