ABSTRACT:
A propeller includes a rotatable hub with a plurality of sockets, blades with roots that fit in the sockets and a plurality of pitch blocks which fit between the blade root and the socket walls. Hubs with two, three, and four sockets are shown. The blades have no twist and are formed of molded, glass reinforced nylon. The pitch blocks are also nylon and different pairs of pitch blocks may be used to hold the blades at different angles. All nylon components are designed to minimize stress concentrations. The hubs although also of nylon have steel reinforcing plates within them which take the centripetal forces. These forces are transmitted through bolts to passage walls in the pitch blocks, and from the pitch blocks through interengaging teeth to the blade roots. A snap on, snap off aerodynamic spinner is also provided.
