Dynamic and Elastic Response of Aircraft in Gust Loads

摘要

Aeroelastic response of gust is always an important problem in flight quality assessment. In this study, structure and aerodynamic solvers based on Lagrange equation and Euler equation are coupled with loose coupling method. Elastic general-purpose airplane and a high-aspect-ratio transport airplane with elastic wings are simulated. The simulations proved the capacity of the method and studied the dynamic response in gust with different conditions.
