中文摘要:座舱压调系统是保障试飞安全的重要系统,座舱压差过大会对飞机结构造成损坏,严重影响飞行安全。对座舱负压差安全释压飞行试验进行了研究,首先介绍了座舱压力调节系统的基本原理和设计特点,随后从试飞方法、改装方法、数据处理、试飞风险几方面对座舱负压差安全释压试飞技术进行了分析总结,可为民机座舱负压差安全释压功能试验提供参考。
英文摘要:Cabin pressure regulating system is an important system to ensure the safety of flight test. The oversize differential pressure often causes damage to the aircraft structure and seriously affects flight safety. The paper studies the flight test of cabin negative differential pressure relief. Firstly the basic principles and design feature of cabin pressure regulating system were introduced, then we analyzed and summarized the cabin negative differential pressure relief flight test including flight test method, refitting method, data processing method and safety evaluation, which can provide some guidances for the cabin negative differential pressure relief flight test of the civil aircraft.
