The embodiment of the invention provides an aircraft pressure relief device and a pressure relief control method. The gas distribution block is provided with a pressure relief inlet and at least three pressure relief outlets; the pressure relief inlet is connected with a pressure relief opening of a to-be-tested aircraft test piece through a main pressure relief pipeline; each pressure relief outlet is connected with the pressure relief inlet through an air channel in the air distribution block. The first throttle valve is arranged on the main pressure relief pipeline; the second throttle valve is arranged on the pressure relief pipeline connected with one pressure relief outlet; and the at least three electromagnetic valves are respectively arranged on the pressure relief pipelines connected with the pressure relief outlets. According to the aircraft pressure relief device and the pressure relief control method provided by the embodiment of the invention, the pressure relief speed and time of the test piece can be adjusted by adjusting the opening degree of the throttling valve and the opening and closing of the electromagnetic valve, so that the pressure relief working condition is met.

    本申请实施例提供一种飞行器泄压装置及泄压控制方法,其中,泄压装置包括:分气块;所述分气块具有泄压入口和至少三个泄压出口;泄压入口通过主泄压管路与待测试的飞行器测试件的泄压口相连;各泄压出口分别通过分气块内的气道与泄压入口相连;第一节流阀,设置于主泄压管路上;第二节流阀,设置于与一个泄压出口相连的泄压管路上;至少三个电磁阀,分别设置于与各泄压出口相连的泄压管路上。本申请实施例提供的飞行器泄压装置及泄压控制方法通过调整节流阀的开度、调整电磁阀的开闭能够调整测试件的泄压速度及时间,以满足泄压工况。
