Calculation Method of Cabin and Cargo Compartment Load limitation for Civil Aircraft

The load limitation of cabin bay and cargo compartment is an important condition for the structure strength design of aircraft floor and the basis for stowage operation. Currently, there is no uniform standard for calculating and analyzing the loading limitation of cabin bay and cargo compartment in domestic civil aircraft. The strength design and verification methods of cabin bay and cargo compartment floor and its supporting structure are diversified and complicated. At the same time, in the actual operation process, if the specified loading limitation is exceeded, the floor of the cabin bay and cargo compartment and its supporting structure may be damaged, further affecting the flight safety of the aircraft. Therefore, combined with the loading situation of the actual operation scene, this paper puts forward a reasonable calculation method for the loading limitation of the cabin bay and cargo compartment, which provides reference for the structure strength design of the floor and its supporting structure and the operation stowage.
