Description

Cargo compartment with self-adaptive gravity center and aircraft

Technical Field

The utility model relates to an aviation technical field, in particular to centrobaric cargo hold of self-adaptation and aircraft.

Background

When an aircraft flies, the flying gravity center plays a crucial role in attitude adjustment and stability of the aircraft, generally, the gravity center of a cargo hold of the aircraft changes due to loading and unloading of cargos, and the loading weight and the loading position of the cargos also have different influences on the gravity center, so that great influence is brought to the control of the flight, and especially when external wind disturbance occurs or a task with larger disturbance is executed, the defect often causes accidents. It is therefore expedient for the centre of gravity of the cargo compartment, and thus of the aircraft, to be adjustable in such a way that the longitudinal passage of the aircraft remains stable.
