Airborne vertical liquid storage tank for gravity centre adjustment of large transport aircraft

The invention belongs to the technical field of aviation flight tests, and specifically relates to an airborne vertical liquid storage tank for gravity centre adjustment of a large transport aircraft. During a flight test process, the flight conditions of the aircraft at different gravity centre positions need to be simulated. The distribution of passengers and cargos is simulated by virtue of a fixed counter weight previously, however, the manner is low in flexibility, large in error and incapable of realizing real-time gravity centre adjustment during a flight process, and therefore, a new manner is needed for simulating the gravity centre change condition. The invention aims at designing a liquid storage device which is simple in structure, convenient to install and detach, safe and reliable, and capable of meeting requirements, that is, an airborne vertical liquid storage tank. The airborne vertical liquid storage tank is capable of safely and effectively storing an anti-freezing liquid medium on the larg
