Title: The Innovations of Ronald E. Barnum
Introduction
Ronald E. Barnum is a notable inventor based in Trumbull, Connecticut. He has made significant contributions to the field of helicopter technology, holding a total of 5 patents. His work focuses on enhancing the stability and control of helicopters, particularly in challenging flight conditions.
Latest Patents
Barnum's latest patents include innovative systems designed to improve helicopter performance. One of his key inventions is a system for helicopter hover stability and cruise gust effect alleviation. This system utilizes the pitch and roll channels of the stability augmentation system to provide positional and attitude stability at low speeds and during hover. It also reduces the effects of wind gusts during level, forward flight at cruise speeds. In this system, true longitudinal acceleration is combined with washed-out vertical gyro pitch for level flight below 60 knots, while above 60 knots, washed-out vertical gyro pitch is used alone. Similarly, the lateral or roll channel integrates true lateral acceleration with vertical gyro roll at speeds below 60 knots, ensuring stability during various flight conditions.
Another significant patent by Barnum is the helicopter pedal feel force proportional to side slip. This invention involves a yaw channel that includes a yaw servo with a trim valve, which can automatically hold heading. At cruise speeds, this system allows for controlled yaw during coordinated turns. The pilot experiences pedal force feel due to the resilient connection to the trim piston, providing feedback on the amount of side slip being created. This innovation helps prevent destructive overloading of the tail rotor.
