Effect of porous inserts on aerodynamics of flying vehicles

Experimental and numerical investigations of a supersonic flow around a cylindrical model with a porous frontal insert made of a high-porosity cellular material performed at the Khristianovich Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences are briefly reviewed. New data on the influence of the angle of attack on the flow around a cylinder with a porous frontal insert are reported. Methods of using high-porosity cellular materials for controlling supersonic flows around axisymmetric bodies are demonstrated.
