Photographed on 12/10/99. -- 29.3% Hyper-X Body-Side Door Inlet Starting Model at the Langley 31-Inch Mach 10 Tunnel. Researcher involved is Dr. Scott D. Holland of the Aerothermodynamics Branch/Aero-and Gas-Dynamics Division. A 2-D model of the Hyper-X forebody was tested to evaluate a body-side door starting mechanism. Typically the inlet cowl is translated or rotated to permit the inlet to start. Such translation or rotation requires complex mechanisms due to the small size of the cowl and inlet sidewalls. A body-side door therefore has the advantage of better packaging for the actuators, but the effectiveness of such a concept was unknown. The model was instrumented for surface static pressures and had a pitot rake at the exit plane. The effects of boundary layer trips were also evaluated. These photographs are cataloged as PHX-008 in the Hyper-X photo archive.
