AERODYNAMIC CHARACTERISTICS OF A BODY OF REVOLUTION WITH GAS-PERMEABLE SURFACE AREAS

摘要

Results of experimental studies and numerical calculations of aerodynamic characteristics of a supersonic flow around a body of revolution with a gas-permeable porous nose cone and an internal duct are presented. At a flow velocity corresponding to the Mach number M = 3, the body considered is found to have a lower drag coefficient (approximately by 9%) than a similar body impermeable for the gas and a lower streamwise static stability.
