Title: Innovations by Donald S. Anttila
Introduction
Donald S. Anttila is a notable inventor based in Southbury, CT (US). He holds a total of 4 patents that showcase his contributions to the field of aviation technology. His work primarily focuses on enhancing the safety and control systems of rotary wing aircraft.
Latest Patents
One of his latest patents is a "Rotary wing aircraft flight control system with a proximity cueing and avoidance system." This invention involves a method of obstacle avoidance for rotary wing aircraft, which includes detecting obstacles near the aircraft and commanding a servo to generate a force to an input control device. This command is designed to prevent the aircraft from contacting the detected obstacle while maintaining lesser authority than a pilot input command.
Another significant patent is the "Rotary wing aircraft proximity warning system with a geographically based avoidance system." This safety enhancement warning system communicates with multiple geographical positional systems. It utilizes a recursive algorithm to determine if the aircraft will enter a sensitive area. If the aircraft's distance to a sensitive area decreases below a predefined minimum threshold, an audible and/or visual warning is issued. Additionally, for certain sensitive areas, the aircraft's RF emissions are silenced or reduced in power when the predetermined minimum threshold is breached. This innovative avoidance system allows the use of relatively inexpensive UWB radar for the proximity sensor suite, ensuring compliance with regulations set by the FCC.
Career Highlights
Donald has worked with prominent companies in the aerospace industry, including Sikorsky Aircraft Corporation and United Technologies Corporation. His experience in these organizations has significantly contributed to his expertise in aviation technology and safety systems.
