Abstract
Blast wave overpressure and dynamic pressure significantly change the surface pressure distribution of the aircraft and resulting in transient aerodynamic forces when the blast wave sweeps the aircraft laterally. These transient aerodynamic forces will pose a serious threat to flight safety. In this paper, the aerodynamic parameters of aircraft components under lateral sweep of blast waves are studied by the Computational Fluid Dynamics (CFD) numerical simulation method, and the waveform characteristics of the dominant aerodynamic parameters of the aircraft key components are analyzed according to the CFD simulation results. The research method can provide reference and guidance for the study of aircraft flight safety under blast wave sweeping.
