Latest Patents

Among his latest patents is the "Pinned Airfoil Propeller Assembly." This invention features a propeller or fan blade that is rotatably mounted to a blade retention pitch member by a pin located radially outside of a spinner. This design allows the blade to respond to vibratory excitation in a way that minimizes twisting motion, thereby enhancing high-speed stability. Additionally, it facilitates the easy replacement of damaged blades.

Another significant patent is the "Pinned Airfoil Propeller Blade." This composite propeller or fan blade is also rotatably mounted to a blade retention pitch member by a pin. The blade consists of multiple composite layers wrapped around a root fairing that engages the pin. This design includes a motion limiter at the base, which dampens rotational movement and minimizes angular excursions during low centrifugal loads. This innovation helps to moderate vibratory motion and tune out undesirable resonant frequencies, while also allowing for a more aerodynamic shape at the root of the blade.
