中文摘要:一个新型的民用飞机要投入航线使用,必须经过适航合格取证试飞,获得型号合格证、生产许可证和适航证,具备三证才允许走向市场。民用飞机适航取证试飞项目有许多,其中负加速度试飞是民用飞机燃油系统适航取证试验的重要验证项目。民用飞机负加速度试飞在国内尚属首次,具有对机组操纵技术要求高、风险难度大的特点。结合某型民机燃油系统合格审定试飞,研究了民用飞机负加速度的试飞技术,提出了用抛物线试飞方法来完成负加速度试飞任务。主要介绍了负加速度试飞中可能出现问题、试飞前应准备的工作、试飞方法等,并对试验结果进行了分析。
英文摘要:Before a new type of civil aircraft get into serves in its airline, it must firstly pass the airworthiness certification flight test , and get the type qualification certification, the production permission certification and airworthiness certification, and then, it is permitted to get into market. There are many different types of airworthiness certification flight test for civil aircraft, in which the Negative Acceleration test is an important one for civil aircraft fuel system airworthiness qualification test. The Negative Acceleration flight test for civil aircraft is the first time attempt in domestic aviation field, this test needs excellent pilot flight skill, and is very high in risk level. In this paper, based on one civil aircraft fuel system certification flight test results, the civil aircraft negative acceleration flight test technique is studied, the "parabolic curve" method is suggested in the flight test mission. The main purpose of the paper is to introduce the problems that will likely be met in negative acceleration flight test, preparation work before the flight test, flight test method, etc, and the test results are analyzed at last.
