Postulowane pomiary widma obciążeń eksploatacyjnych skrzydeł szybowców w locie

The problem of a programme on ground fatigue tests, as a base for glider life estimation has been presented. The structure of loading spectrum and it's parameters has also been described. The load level and frequency depending on the glider operation patterns are represented by the particular loading blocks. To prepare the ground test programm the structure of particular loading blocks should be defined on the base of flight measurements of load spectrum. The results obtained recently have been presented and the way of application to the fatigue test programm for the performed tests have been discussed.
