摘　　要：对阻力伞、气囊等柔性减速器进行了风洞试验研究。采用高速摄像清晰地记录了阻力伞在M=1.0条件下的开伞过程、气囊在M=6.0条件下充气过程的外形变化,准确地测得了气囊在M=6.0条件下充气过程的阻力时间历程,且气囊充气过程外形变化的时间历程与阻力时间历程相符。此外,对阻力伞高速风洞试验的堵塞度影响进行了研究。结果表明,通过研究,为柔性减速器的气动特性测试建立了新的试验技术。Wind-tunnel experiments have been performed to study the aerodynamics of flexible decelerators such as drag parachutes and airbags. The deployment process of a drag parachute at M = 1.0 and the deformation of an airbag during the inflation at M = 6.0 were recorded using high-speed camera. The time history of the drag was shown to match the shape change of the airbag very well. The blockage effects of the drag parachute have been also studied. Test results show that new techniques developed in the present studies can be successfully used in studying the aerodynamics of flexible decelerators.
