摘要
根据试飞数据进行飞机平飞加速性能分析,区别于以往的平飞加速性能分析方法,而是以试飞数据为基础,在对数据进行分析处理后,建立数学模型进而分析飞机的平飞加速性能。此方法既可以作为传统飞机平飞加速性能计算的一种参考,又从实际的实验数据出发,使得计算结果更加真实可靠。通过此种方法还可以预测出飞机在实际飞行中的性能极限数值,大大的减小了飞机的试飞周期,提高了试飞效率。在整个新机研发过程中,缩短了新机科研试飞周期,为保证飞行安全提供了可靠的技术支持。
A method of analyzing the level acceleration performance which is different from the past method based in the flight test data is proposed. It analyses the level acceleration performance by setting up the mathematical model. The method can be used as a reference to the traditional method and a tool to improve test efficiency. According to the real test data, it makes the result more reliable. With the method, we can forecast the limit of performance of flight test. The method decrease the cycle of flight test, and improve test efficiency. In the whole process of new aircraft development, the method shorten the cycle of new aircraft flight test and provide the technical support of flight safety.
