飞机载荷谱飞行实测对确定飞机实际使用寿命、改进飞机结构设计有着非常重要的作用。本文通过试飞方案设计和飞机重心法向过载概率分布确定两部分工作,证明了将试验设计应用到受多重因素影响的飞机载荷谱飞行实测中的合理性、可行性和必要性,最终在同时保证安全性和经济性的前提下实现了优化试飞架次的目标,为未来的新机试飞提供了一条新的方法和途径。 Aircraft load spectrum flight measurement to determine the actual life of aircraft, aircraft structure design to improve has a very important role. In this paper, we design two parts of the test program design and the probability distribution of the normal center of gravity of the aircraft center, and prove the rationality, feasibility and necessity of applying the test design to the aircraft load spectrum flight measurement affected by multiple factors. Finally, at the same time, Safety and economy under the premise of achieving the goal of optimizing the test flight times for the new aircraft test flight provides a new way and approach.
