Abstract:
The unsteady aerodynamic loads generated by the thin-shell object separating from aircraft affect flying safety. To investigate the loads, a method combining numerical simulation and experiment is proposed. Firstly, the motional tendency of the thin-shell object separating from aircraft is calculated, and then the high-speed air blowing test on ground is designed. Thereafter, the external store is employed to avoid colliding with the thin-shell object in air. Finally, the hanging and flight test is conducted by a high-speed unmanned aerial vehicle (UAV), and the feasibility of the thin-shell object separating from aircraft at high speed is proved. Consequently, the separating problem of a thin-shell object with an unconventional aerodynamic configuration is solved, and the collision with aircraft is prevented.
