Supersonic air intake passage capable of achieving synchronous adjustment of capturing area and throat area

A supersonic inlet with synchronous adjustment of a capture area and a throat area, comprising a first stage compression surface located on an inner side of an entrance of an inlet, a second stage compression surface extending backward from the first stage compression surface, a cowl lip located on an outer side of the entrance of the inlet, a movable inner contraction section hinged on a rear end of the second stage compression surface and extending backward, a movable throat section hinged on a rear end of the movable inner contraction section and extending backward, and a movable diffuser section hinged on a rear end of the movable throat section and extending backward;

• the cowl lip comprises a fixed cowl section located on the rear end and a rotatable cowl section hinged on a front end of the fixed cowl section and extending forward, the rotatable cowl section may rotate inward or outward around its hinge point with the fixed cowl section.
