What type of inlet is designed for aircraft operation in both subsonic and supersonic flight regimes? How does it work?



Answer: The Variable Geometry Inlet Duct uses mechanical devices such as wedges, ramps, or cones to automatically (no pilot input required) change inlet shape as aircraft speed varies between subsonic and supersonic.
