在航空工业生产,新机研制和航空科学理论研究中需要做大量试验工作来鉴定产品是否合格,新机是否满足设计要求并积累科学研究的原始资料。这些试验如飞机与导弹模型的气动力试验,飞机结构的静、动力强度试验,喷气和火箭发动机台架试车,高空模拟试验,飞行试验等等。其中有的由于试验本身只能在极短时间内进行,如法国宇航研究院莫当S3暂冲式风洞,一次试验才1分钟;有的由于试验过程准备工作、投资,规模均很大,如一架大型飞机的全机静力试验准备周期达半年之久,
In aviation industry production, new aircraft development and aeronautical science research, a large amount of test work needs to be done to identify whether the product is qualified, whether the new aircraft meets the design requirements and accumulates the original data of scientific research. These tests include aerodynamic testing of aircraft and missile models, static and dynamic testing of aircraft structures, bench testing of jet and rocket motors, aerial simulation tests, flight tests and more. Some of them can only be carried out within a very short period of time. For example, the aeronautical research institute of French Aeronautics S3 transient-induced wind tunnel is only one minute in one trial. Some of them have large investment and large scale due to preparation for the trial. Such as a large aircraft static test preparation period of up to six months,
