Investigation at Mach Number 1.88 of Half of a Conical-spike Diffuser Mounted as a Side Inlet with Boundary-layer Control / H. Fred Goelzer and Edgar M. Cortright, JrExperimental investigation was conducted at Mach number 1.88 to determine performance characteristics of half a 50 degree-conical-spike inlet mounted on a flat plate. Initial boundary layer was removed up-stream of inlet by a ram-type scoop of variable height. Initial boundary-layer thickness was also varied. With complete removal of initial boundary layer, total-pressure recovery of approximately 70 percent. Several alternative boundary-layer-removal systems were investigated which decreased the adverse effect of operating the ram scoop sub-critically.
