- Abstract
Results of experimental and numerical investigations of a supersonic flow of cylindrical models aligned at a zero angle of attack with frontal inserts made of cellular porous nickel are reported. The experiments are performed in a supersonic wind tunnel at Mach numbers and 7.00 and unit Reynolds numbers and m , respectively. Numerical simulations with the use of a ring-shaped skeletal model of the porous material are also performed. A possibility of drag control is studied for two thermal methods: external heating of the porous insert and internal heating of the insert by a glow discharge. The mechanisms of the thermal action and the efficiency of the thermal methods of drag control are analyzed.
