The invention provides a helicopter flight parameter trend analysis method. The helicopter flight parameter trend analysis method comprises the following steps of 1, obtaining flight parameters of N continuous sessions; n is an integer greater than 10; 2, according to the types of the flight parameters, representative values of the flight parameters of N continuous sessions are obtained; 3, obtaining a broken line graph according to the representative values of the flight parameters of the N continuous sessions; and 4, determining the trend of the broken line graph, and determining whether fault analysis needs to be performed on the helicopter according to the trend of the broken line graph. According to the method, when parameters do not change qualitatively, trend monitoring analysis is carried out on quantitative change conditions of key parameters by using a data analysis means easy to implement, potential safety hazards are found and eliminated in advance, possible qualitative change is prevented, and the perfectness ratio of the helicopter is improved at the lowest cost. The flight parameter trend analysis method can play an important role in daily maintenance of the helicopter.

    本发明提供一种直升机飞参趋势分析方法,包括以下步骤:步骤一:获取N个连续场次的飞行参数;N为大于10的整数;步骤二:根据飞行参数的类型,获取N个连续场次的飞行参数的代表值;步骤三:根据N个连续场次的飞行参数的代表值,获取折线图;步骤四:确定折线图走向趋势,根据折线图走向趋势确定是否需要对直升机进行故障分析。本发明研究在参数未发生质变时,通过使用容易实现的数据分析手段,对关键参数量变情况进行趋势监测分析,提前发现并排除安全隐患,预防可能发生的质变,以最低成本提升直升机的完好率。飞参趋势分析方法,可以在直升机日常维护中发挥重要的作用。
