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.
