Method and system for plane load balancing and optimization

Abstract

The invention provides a method of plane load balancing and optimization. According to the method of the invention, load optimization combination is carried out according to a loading balancing and optimization criterion, the placing position of a cargo loading unit, and in a corresponding loading process, the cargo centre-of-gravity position after placement is controlled in a designed and required range. When the embodiment of the invention is executed, on the premise of meeting boy gravity center requirements in the case of flight, influences of the cargo loading layout on bending moment and torque borne by the body are fully considered, the cargo placement rationality is ensured, the flight safety is ensured, and the maximum cargo loading amount is realized.

Description

technical field [0001] The invention relates to the technical field of aircraft cargo loading, in particular to a method and system for aircraft load balance and optimization. Background technique [0002] Air cargo is a fast and efficient logistics method. According to Boeing's forecast at the 2014 International Air Cargo Forum held in South Korea, the average annual growth rate of the global air cargo market will reach 4.7% in the next 20 years. It can be seen that further realizing high-efficiency air cargo industry has great market development prospects. While strengthening the development of air cargo potential, the safety of air transport cannot be ignored. A flight with unreasonable counterweight will endanger the safety of the overall structure of the aircraft and have a harmful effect on the performance of the aircraft. The Netherlands National Aerospace Research (NLR) recently conducted a study on unsafe events related to aircraft load balance in the world from ...

Problems solved by technology

[0003] Unreasonable loading of the aircraft will cause the center of gravity to deviate from the allowable range, and it will also cause control difficulties during the flight, and even symptoms of flight accidents. When the balance point falls outside the safe range during takeoff and landing, it may also lead to the consequences of aircraft crash and death

For example, Flight 5481 of China West Airlines stalled and crashed due to the improper use of average weight when calculating the balance after the center of gravity passed. In addition, a certain European airline once had a cargo plane because the loaders piled too much cargo on the plane when distributing the cargo. The head and tail of the aircraft encountered turbulence during the landing process, which eventually caused the entire aircraft to break from the middle
