Theory and Test Method and Innovation of Life Reliability Assessment for Aircraft Structures in China
YAN Chuliang;Beijing Aircraft Strength Institute;
The research of life reliability for aircraft structure in China has lasted for more than 40 years, under the guidance of Gao Zhengtong, academician, a series of aircraft economic life reliability theories have been established, the principle of compiling aircraft median load spectrum has been developed, and the calibration method and test technology of multipoint coordinated loading of the whole aircraft hovering in place have been invented. Over 20 types of aircraft load spectrumresearch and development missions have been completed, which solved the problem of using one aircraft to carry out load spectrum measurement to predicate and extend the life for the aircraft group in China. The research results have been successfully applied to the life determination, life extension and the design of structural reliability of thousands of aircrafts, which made an important contribution to improve the service life of aircraft in service significantly and ensure flight safety.
