This invention discloses an aircraft with a folding and locking mechanism, belonging to the field of unmanned aerial vehicle (UAV) technology. The device includes a mounting housing and a self-locking mechanism and a locking mechanism located inside it. The self-locking mechanism has a supporting rotating shaft connected to the arms via a driven gear. The locking mechanism includes a corrugated expansion tube connected by a fairing and a flexible hose. The corrugated expansion tube drives a wedge-shaped pusher with a toothed lower end; the wedge-shaped pusher engages with a sliding rack, which is connected to the driven gear. Rotating a knob on the top of the housing drives a rotating disk, whose inclined top column simultaneously lifts all the wedge-shaped pushers. This invention, through a purely mechanical structure, utilizes the airflow pressure during flight to drive the corrugated expansion tube, causing the wedge-shaped pushers to press down and push the rack to slide, thereby automatically folding and locking the gears and arms to adaptively adjust the wind-receiving area and enhance wind resistance stability; all arms can be simultaneously unlocked by rotating a single knob, enabling rapid manual folding.

The present invention relates to a casing intended to be externally applied, connected or fixed to the fuselage or to a wing of an aircraft or to a central or wing station / hardpoint of an aircraft, the casing entirely or partly delimiting a housing zone (HZ) of a super-orbital, orbital or sub-orbital launch vehicle.
