However, aircraft engines are difficult to install due to their large size, heavy weight, complex structure, and small installation clearance, making it difficult to achieve precise attitude adjustment and positioning during loading and unloading of aircraft engines. The loading and unloading quality will have a significant impact on the power performance of the aircraft.

[0003] When the aircraft engine is arranged under the wing of the aircraft and the installation space is large, or when the aircraft engine compartment is open at the top, the engine is usually installed by hoisting, which is mainly used for the installation of some light engines: a large crane is used to lift the aircraft engine to the installation location. Then the aircraft and the engine are connected and fixed.
