Methods and Techniques of Airframe Strength Flight Tests

摘要

Methods of flight tests for evaluating the strength of airplanes and helicopters are presented. The basic types of modern measurement equipment used for measuring vibrations, stresses, temperatures and other parameters are described and recommendations are given concerning the preparation and calibration of the equipment. Brief information on laboratory airframe tests is included. Mehtods of flight tests for strength in which loads and vibrations are measured are discussed. Methods of analyzing measurement data in terms of airframe load features are presented. The basic computer hardware used for processing and analyzing measurement results are described. (Author)
