Abstract

Matter presented in the paper concerns the research determining operation life of the PW-5 World Class Glider. The investigation was divided in two planes: A. Records of the glider's loads in the air and estimation of the load spectrum of the glider, B. Modeling these loads on the stand for fatigue test of the glider's main structure. The glider's loads were recorded on the PW-5 glider equipped with digital recorder and deflection-sensor of the wing-spar-root and electranic accelerometer fixed in the glider's gravity center. The load spectrum was obtained using original data processing briefed in the paper. It was applied to the fatigue tests of the wing-fuselage-set. The paper contains also the description of the original resonance electrodynamic load method and remarks frrom the present stage of the research.
