Abstract

This report describes the development of an integral simulation model for flexible aircraft and its application to the flight loads analysis of wake vortex encounters of a large transport aircraft. The aerodynamic model consists of a databank containing the steady aerodynamic loading oft the quasi-flexible aircraft combined with an unsteady vortex lattice method for lifting surfaces and bodies. To improve accuracy and computational performance, a correction method based on steady reference data and an order reduction method are introduced. Aeroelastic coupling of the aeroelastic model to the structural model is achieved by a method based on finite interpolation beam elements. A parameterized wake vortex encounter is used to determine the loads-critical encounter type and to illustrate the impact of aircraft modeling on the obtained loads.
