Drive system for e.g. ultra-light aircraft, has gear-wheels standing in engagement at bevel-gears of blades, and electro-motors driving wheels independent of each other, where blades are rotatably supported for adjusting engaging angles

摘要

The system has a variable pitch propeller with a symmetrical axis (1) and three blades (10), which are rotatably supported for adjusting blade engaging angles along a longitudinal axis of the blades and exhibit bevel-gears (11). Two drive gear wheels (45, 55) are arranged at the symmetrical axis and stand in engagement at the bevel-gears of the blades. Two electro-motors (40, 50) are connected with the gear-wheels, which are driven by the electro-motors independent of each other.
