The invention belongs to the field of airplane strength tests, and particularly relates to an airplane ground pressurizing test method. The method comprises the steps that S1, a filling air bag is fixed in the aircraft, and the filling air bag is inflated through a first air source; s2, after the filling air bag suspends in the aircraft, inflating the interior of the aircraft by a second air source, and continuing to inflate the filling air bag by the first air source according to a pressurizing load spectrum for inflating the interior of the aircraft; and S3, performing closed-loop control on each inflation loop based on the pressure difference between a first contact barometer for monitoring the pressure in the filling air bag and a second contact barometer for monitoring the pressure in the airplane. According to the invention, filling and loading control can be rapidly realized, the test efficiency is improved, and the test risk is reduced.
本申请属于飞机强度试验领域,特别涉及一种飞机地面充压试验方法。该方法包括步骤S1、在飞机内部固定填充气囊,并由第一气源向所述填充气囊内充气;步骤S2、当所述填充气囊悬浮于飞机内部后,由第二气源向飞机内部充气,并按照向飞机内部充气的充压载荷谱继续由第一气源向所述填充气囊内充气;步骤S3、基于监测所述填充气囊内压力的第一触点气压表与监测飞机内部压力的第二触点气压表之间的压差对各充气回路进行闭环控制。本申请能够快速实现填充和加载控制,提高试验效率,降低试验风险。
