摘　　要：为研究大容积、复杂结构的客机机身增压舱进行多充压点增压试验时舱内流场分布的规律,通过数值分析方法,合理选择压力传感器检测点,实现充压点输入控制参数值与舱内压力检测反馈值的闭环控制,达到了试验过程的精确控制,提高了试验效率。该型客机机身增压舱增压试验数据表明,按照数值分析方法选取的3个压力检测点反馈值能够快速、同步达到试验目标值,峰值超差在试验允许范围内,稳压值满足试验要求,试验方法科学合理。In order to study the distribution law of flow field in the cabin of a large-volume and complex structure airliner fuselage booster chamber during Multi-Filling point pressurization test,the pressure sensor monitoring points are reasonably selected by numerical analysis method,and the closed-loop control between the input control parameters of the filling point and the feedback value of the cabin pressure monitoring is realized.The precise control of the test process is achieved and the test efficiency is improved.The data of turbocharging test for the fuselage booster cabin of this type of passenger aircraft show that feedback values of three pressure monitoring points selected according to the numerical analysis method can quickly and synchronously reach the test target value.The peak overshoot is within the allowable range of the test,and the voltage stabilized value meets the test requirements,which indicates that the test method is scientific and reasonable.
