The paper presents the research into determining of operation life of the PW-5 World Class Glider. The investigations were conducted at the following two stages: a/ recording of the loads acting upon the glider in the air and estimation of the load spectrum, b/ modeling of the loads on an experimental stand for glider's main structure fatigue test The loads acting upon the glider were recorded on the PW-5 glider equipped with a digital recorder and deflection-sensor of the wing-spar root structure and electronic accelerometer fixed at the glider center of gravity. The load spectrum - was obtained using unique data-processing system described briefly in the paper. It was applied to the fatigue tests on the wing-fuselage-set. The paper presents also the description of the unique resonance method based on electrodynamic impulses.
