Effect of a Concentrated Injection at the Forward Stagnation Point of a Blunt Body under Hypersonic Conditions

摘要

A preliminary set of results are presented on the effects of high rate of injection localized at the forward stagnation point of a blunt body under hypersonic conditions. The device is envisaged as a possible mean to deform the 'effective shape' of noses of vehicles reentering from interplanetary missions; an attempt is made to establish an analogy with spiked bodies. Pressure distribution and heat transfer data are obtained for a Mach number equal to 8 and Reynolds number 2/3 and injection rates ranging between C = 1/6. (Author)
