Analysis of factors affecting the stability of aircraft engine test

Abstract Although the aircraft is in a braking and shutdown state during engine testing, there may still be situations where the aircraft slides or deviates during the development process, which affects the safety of the aircraft. This article establishes a force analysis model for an aircraft engine test and proposes a single-engine testing force analysis method based on dual-engine testing force analysis. Factors such as the friction coefficient of pavement, wind speed, and aircraft parking slope are taken into account in the calculation. The relationship between different influencing factors and ground stability is studied in the article. The article provides a reference for the weight center of gravity limitation of aircraft under engine ground testing conditions.
