Title: The Innovations of Robert J Ewy
Introduction
Robert J Ewy is a notable inventor based in Olathe, Kansas, with a focus on advancements in aviation technology. He holds two patents that showcase his innovative contributions to the field. His work primarily revolves around enhancing the functionality and safety of aircraft systems.
Latest Patents
One of Ewy's latest patents is the "Differentially Coupled Dual Channel Actuator." This invention is designed to regulate control surfaces of aircraft, such as helicopters. The actuator features primary and secondary channels that are coupled by a differential gear. An internal stop within the differential gear limits the short-term range of travel for the primary channel, while the secondary channel allows for extended long-term authority by recentering the reference point for the primary channel's rotational range. The primary channel consists of a servo motor and primary input gear, while the secondary channel includes a second servo motor and secondary input gear. The reference point is established by a stop pin connected to the differential gear.
Another significant patent by Ewy is the "Acceleration Sensitive Switch." This switch structure is designed to detect acceleration in a specific direction, such as along the pitch axis of an aircraft. It features a spring-supported mass that is urged toward a stable centered position within the housing. When acceleration occurs, the mass is displaced, triggering a spring wire switch mechanism that controls avionic devices like the autopilot system. The switch includes solenoid coils wound around the spring mass system, allowing for preflight testing by energizing the coils to attract the mass toward the center of the solenoid fields.
