Abstract: A system and method for providing a supplemental power includes: an engine, a transmission coupled to the engine, a motor-generator coupled to the transmission, and a battery system coupled to the motor-generator. The motor-generator is configured to draw an energy from the transmission and store the energy in the battery system when the engine is driving the transmission. The battery system is configured to discharge the energy to the motor-generator, and the motor-generator is configured to provide the supplemental power to the transmission.

Abstract: A system and method for providing supplemental power includes: a motor-generator or a hydraulic pump-motor configured to attach to a transmission of an engine, a controller connected to the motor-generator or the hydraulic pump-motor, and a battery system or a hydraulic accumulator coupled to the motor-generator or the hydraulic pump-motor, respectively. During normal operation of the engine, the engine drives the transmission to rotate rotor blades connected to the transmission, and the motor-generator or the hydraulic pump-motor draws an energy from the transmission and store the energy in the battery system or the hydraulic accumulator, respectively. Upon a manual and/or an automatic control by the controller, the battery system or the hydraulic accumulator discharges the energy to the motor-generator or the hydraulic pump-motor, respectively, and the motor-generator or the hydraulic pump-motor provides the supplemental power to drive the transmission to rotate the rotor blades.

Abstract: Embodiments refer generally to systems and methods for providing autorotative enhancement for helicopters using an autorotative assist unit coupled to the transmission of the helicopter. Methods of utilizing an autorotative assist unit as well as retrofitting an autorotative assist unit to an existing helicopter are also disclosed. By employing an autorotative assist unit, improved autorotation can be achieved without the need to increase the weight of the rotor.

Abstract: An autorotative enhancement system comprises a transmission having a driveshaft configured to couple to an engine. A mast is configured to couple to multiple rotor blades. An autorotative assist unit is configured to the transmission and is configured to store energy during normal operation and drive the rotor blades through the transmission to provide supplemental autorotative assistance upon loss of engine power.
