The invention provides a drop test system and a drop test method for a whole aircraft. The drop test system comprises a lifting mechanism which is connected with a crane of a test workshop and is usedfor lifting or releasing the aircraft, a measuring platform which is arranged below the lifting mechanism, is used for bearing the released aircraft, and comprises a bearing platform which comprisesa central hole, a group of force measuring sensors which are arranged on the ground below the bearing platform and are used for providing support for the bearing platform, and a speedometer which is arranged below the central hole and is used for measuring the sinking speed of the aircraft. The crane of the test workshop is used for suspending the aircraft, so that the universality is higher, thecost is low, and the use is convenient; the integrated lifting mechanism is driven by a motor to achieve lifting and releasing of the aircraft, a manual winch is replaced, manpower can be saved, and the lifting mechanism can be suitable for heavier aircrafts; and the aircraft sinking speed is obtained in the test process, and the test specification requirements are met.

    本申请提供一种飞机整机的落震试验系统及落震试验方法,所述落震试验系统包括:升降机构,与试验厂房的起重机相连,用于抬升或释放飞机;测量平台,设置于所述升降机构下方,用于承接释放的飞机,包括:承载平台,包括中央孔;一组测力传感器,设置于所述承载平台下方的地面上,为所述承载平台提供支撑;测速仪,设置于所述中央孔下方,用于测量飞机的下沉速度。利用试验厂房的起重机对飞机进行悬挂,更具通用性、成本低、使用便捷;使用电机驱动一体化的升降机构实现飞机的抬升和释放,代替手动绞盘,既可以节约人力又可以适用于更重的飞机。在试验过程中同时获得飞机下沉速度,满足试验规范要求。
