The unsteady aerodynamic loads generated by the thin-shell object separating from aircraft affects 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 collisions with aircraft is prevented.
The unsteady aerodynamic loads generated by the thin-shell object separating from aircraft affects flying safety. Tension of 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 the 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 proven. Reconstituted, the separating problem of a thin-shell object with an unconventional aerodynamic configuration is solved, and the collisions with aircraft is prevented.
