A mixed compression inlet having a forward ramp, an aft ramp, and a slot therebetween is disclosed. The aft ramp is coupled to the inlet to permit both fore-aft movement and rotational movement. The geometric throat of the inlet is located at the leading edge of the aft ramp. The slot opens into a plenum chamber. A vent permits air to exit from the plenum chamber. The pressure in the plenum chamber is maintained approximately equal to the pressure on the aft portion of the forward ramp. A servocontroller receiving input from pressure sensors of the forwa...


An inlet having an inlet duct for an aircraft engine, comprising: a cowl having a cowl lip, said cowl forming a wall of said inlet duct; a forward ramp having a leading edge positioned forward of said cowl lip and a trailing edge extending aft of said cowl lip; a aft ramp positioned within said inlet duct aft of said cowl lip; a throat region within said duct at a leading edge of said aft ramp; means for simultaneously rotating and moving said aft ramp fore and aft for varying the cross-sectional area of said throat simultaneously with changing the locat...
