Abstract:

Present research at home and abroad on landing gear wheel load tends to focus on its total loading, while study of specific landing gear wheel load distribution is rarely seen. However, there is an urgent need in engineering to develop an appropriate method to calculate aircraft landing gear wheel load distribution. This article studies the impact of the roughness of the airport on the tricycle type undercarriage wheel load distribution and presents a calculation method for the load distribution of the wheels. The effectiveness and feasibility of the method are demonstrated by calculating the wheel load distribution of a Boeing 707 aircraft.

Key words: tricycle-type landing gear, roughness of airport, wheels, load distribution
