Introduction
Thomas C. Hermans is a notable inventor based in Cincinnati, OH, who has made significant contributions to the field of aircraft propulsion systems. With a total of four patents to his name, Hermans has demonstrated a commitment to advancing technology in aviation.
Latest Patents
One of his latest patents is the "Aircraft Pitch Change Mechanism." This innovative system allows for the adjustment of pitch in aircraft propfans through a motor located at a stationary position, utilizing a gear train. The system features a feather brake that can override the motor to drive the blades toward feather, a unison brake that prevents pitch excursions toward fine pitch when propeller speed exceeds a limit, and a motor that remains non-rotating in the absence of pitch change. Additionally, a pair of such systems can be employed in a counter-rotating propfan system to independently change the pitch of the propfans. Another significant patent is the "Fan Blade Protection System." This invention addresses the issue of propeller blades mounted on a ring surrounding a turbine. It reduces deformation caused by unbalanced centrifugal loads by strategically placing spacers between the turbine and the ring.
