The invention relates to the technical field of airplane state function detection, in particular to an airplane oxygen supply system performance simulation joint test method, which comprises the steps of ground oxygen supply simulation: opening a pressure component on airplane oxygen supply system performance simulation joint test equipment; the oxygen flow meter displays the flow in the'pure oxygen 'state and the'emergency' state in real time, and the time for supplying a large amount of oxygen is measured by calculating the sudden change amount of the flow of the oxygen flow meter; in the air oxygen supply simulation, a pressure regulator in an oxygen supply system is in a pressurized state; the parameters are consistent with ground oxygen supply simulation test parameters; performing anti-load oxygen supply simulation: adjusting a pressure regulator in the oxygen supply system to a'pressurization 'state; a'blue-black flow indicating valve 'of an oxygen comprehensive indicator in the oxygen supply system indicates blue, a'height' window indicating value is consistent with the vacuum height, and a'delta P 'indicating value is a pressure difference value. According to the invention, the requirements of joint test fault inspection and test verification of the oxygen supply system are met; the fault judgment accuracy is improved by more than 90%, and the working efficiency is improved by more than 50%.

    本发明涉及飞机状态功能检测技术领域,具体为一种飞机供氧系统性能模拟联试方法,包括地面供氧模拟:打开飞机供氧系统性能模拟联试设备上的压力部件;氧气流量计实时显示“纯氧”和“应急”状态下的流量,通过计算氧气流量计的流量突变量测出大量供氧的时间;空中供氧模拟:供氧系统中的压力调节器置于“加压状态”;与地面供氧模拟测试参数一致;抗荷供氧模拟:供氧系统中的压力调节器调至“加压”状态;供氧系统中的氧气综合指示器的“蓝黑示流活门”指示为蓝色、“高度”窗口指示值与真空高度一致、“ΔP”指示值为压差值。本发明达到了供氧系统联试故障检查和测试验证要求;将故障判断准确性提高了90%以上,提高工作效率50%以上。
