Abstract:

The report presents the results of an investigation of the design and performance characteristics of a compact and lightweight stability augmentation system for helicopters. This system, known as the DYNAGYRO, consists of a two- degree-of-freedom coulomb damped gyroscope which is mounted within the helicopter fuselage. The investigation includes an analog computer study, a comprehensive component test program, and a bench test performance evaluation of a laboratory test model. The results obtained from the investigation showed that the DYNAGYRO provides stability augmentation characteristics which compare favorably with those of the much larger and heavier rotor hub-mounted devices.
