An aeroshell is a rigid heat-shielded shell that helps decelerate and protects a spacecraft vehicle from pressure, heat, and possible debris created by drag during atmospheric entry (see blunt body theory). Its main components consist of a heat shield (the forebody) and a back shell. The heat shield absorbs heat caused by air compression in front of the spacecraft during its atmospheric entry. The back shell carries the load being delivered, along with important components such as a parachute, rocket engines, and monitoring electronics like an inertial measurement unit that monitors the orientation of the shell during parachute-slowed descent.
An aircraft with a folding locking mechanism
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.
