Latest Patents
Schibler's latest patents include a process for making an injection molded fan blade. This invention focuses on a variable pitch fan for helicopters equipped with a NOTAR™ mechanical antitorque directional control system. Each blade assembly consists of a blade portion molded from a blended material that includes fiber reinforced polypropylene. A key aspect of this invention is the use of long fibers, which provide approximately twice the pull-out strength compared to short or chopped fibers. Additionally, the incorporation of a blowing agent in the blended material reduces weight and warpage by creating a foamed structure with variable density, while still retaining considerable strength due to fiber reinforcement. The blade portion is molded around a spar with holes that create a mechanical interlock between the blade and the spar.
