Adjustable propeller for ultra-light aircraft

摘要

The propeller has a hub-side open ribbed tube (3) which is fixed in each blade (2). A hollow shaft (4) is fixed in the hub (1) and extends radially outwards. The ribbed tube is pushed onto the hollow shaft to create a sliding bearing on which the blade can rotate. A torsion body (5) is present in a section of the hollow shaft and joined at one end to the blades and at the other end to the hub. The propeller can have two blades or three blades arranged symmetrically.
