The Morphing Mechanism Design Applying Computer Simulation Technique for Folding Wing Aircraft

摘要

The morphing mechanism is the key technique for preliminary design of folding wing aircraft. In the morphing process, aerodynamic loads estimation and dynamic response analysis of the folding wing must be considered. In this paper, the computer simulation technique including Vortex Lattice Method (VLM) program and LMS Virtual.Lab was adopted in modeling and analysis for the aerodynamic loads distribution along wingspan and the dynamic response characteristics in morphing process. Then the detail design was completed according to the simulation results. Finally, the feasibility and reasonability of the project were validated by model aircraft flight test.
