Investigation of the glider load spectra
Keywords:Structures, Materials, Design
The paper presents the results of work aimed at the investigation of the load spectra. The investigated object was a PW-5 glider equipped with a wing-spar root deflection measurement and accelerometer. The records of the loads were made during several flight-tasks: thermal flying, soaring, wave-flying and aerobatics. The results of the investigation are presented as load spectra in the form of the Markov-matrix. A second subject concerns the extrapolation of the load spectrum recorded during investigations for extended-time operation. The third problem reported is the comparison of the calculated damage accumulation effect induced by different load spectra.
