Design of a High Reynolds Number Mach Number 8 Contoured Nozzle for the Hypervelocity Wind Tunnel (F).
Abstract
The report describes the aerodynamic design of a Mach 8 contoured nozzle for a hypervelocity wind tunnel. The nozzle is expected to operate over a broad range of reservoir conditions including temperatures and pressures which will allow the simulation of flight conditions at 70,000-ft altitude. Both tunnel blockage considerations and tunnel core size estimates indicate that 4.5-in.-diam 'very blunt' 6-in. diam hemisphere models, and larger diameter sharp nose models could be tested. This method may be used to extrapolate boundary-layer predictions to higher Reynolds numbers. (Author)
