Location for propeller blade made of fibre cpd. - has loop rail with bearing shaft extending through propeller blade root with loop rail extending around bearing shaft

摘要

The bearing shaft (2) is formed at approximately 90 deg. to the longitudinal axis of the propeller blade and the loop rail (12) is of one-piece construction. The loop rail is arranged at approximately 90 deg. to the profile longitudinal axis parallel to the bearing shaft (2) on the propeller blade rail (1). The propeller blade root (13) is rectangular and to accommodate the bearing shaft has a bearing bush (8). On the outside (14) of the propeller blade root damping elements are arranged (5). The accommodation aperture (15) of the propeller blade casing (4) for the propeller blade root (13) widens outwards in the area of the damping elements (5). USE/ADVANTAGE - A propeller blade location for aircraft and of ground effect vehicles in which the bearing shaft is arranged at 90 deg. to the profile longitudinal axis of the propeller blade, with the loop rail being of one-piece construction.
