Abstract

The article presents results of an experimental investigation of supersonic flow around of a longitudinal flow cylinder with a gas-permeable porous front insert. The main attention is paid to the influence of porous material characteristics of the front insert on the aerodynamic drag. The experiments were performed in wind tunnels at Mach number 4.85; 7 and 21. The used porous materials are a cellular-porous nickel, a fibrous porous material such as "metal felt" and a porous material formed from superimposed nets. The important role of the ratio of the cylinder diameter to the pore diameter in the aerodynamic drag of the model is shown for cellular-porous nickel. The data of numerical modeling of the flow around the model were used in order to reveal the physical mechanisms of the influence of the front porous insert on the aerodynamic drag.
