초록
▼

A mixed compression supersonic inlet system is provided which includes an external cowl, and an axisymmetric centerbody which preferably translates fore and aft. The centerbody of the inlet system is further provided with indexing segments which circumferentially rotate to provide longitudinal grooves or channels located on the outer periphery of the centerbody and which increase the effective flow area of the inlet. As the indexing segments rotate circumferentially, the channel width varies. The centerbody may also be provided with indexing segments for...

[ We claim:] [1.]1. An inlet for use in an aircraft comprising:a translating axisymmetric centerbody comprising a curved exterior surface of varying height along a longitudinal axis of the centerbody and a cowl mounted about said centerbody and forming an annular duct therein;one or more channels formed on the periphery of said centerbody, with each channel having opposed sidewalls extending longitudinally along said centerbody and a bottom wall connecting said sidewalls; andone or more slidable segments for insertion into a respective channel, each of s...
