Title: Innovations by David L Joyce
Introduction
David L Joyce is a notable inventor based in West Chester, Ohio. He has made significant contributions to the field of aviation technology, holding a total of four patents. His work primarily focuses on systems that enhance aircraft performance and safety.
Latest Patents
One of Joyce's latest patents is the Sensor Ice Shield. This innovative system is designed to reduce ice mass on aircraft engines. It utilizes a compressor inlet temperature and pressure sensor to measure total temperature and pressure at the engine compressor's inlet. The ice shield features a plurality of wedge portions with multiple protrusions that promote ice formation in various locations. This design minimizes ice accretion in desired areas, ensuring that the mass of any resultant ice formation is manageable for the compressor inlet blades.
Another significant patent is the Aircraft Pitch Change Mechanism. This system allows for the adjustment of pitch in aircraft propfans through a motor located at a stationary position, which changes the pitch of the blades via a gear train. The system includes a feather brake that can override the motor, a unison brake to prevent unwanted pitch changes, and operates without rotation when no pitch change is needed. This mechanism can be utilized in counter-rotating propfan systems to independently adjust the pitch of the propfans.
