1.1 General

The Shergood Steamly S2-S is a single-engine steam-turbine powered helicopter. It employs a closed-loop steam system consisting of a boiler, a steam turbine, a condenser and a water reservoir. A fuel oil burner in the boiler provides the heat to produce steam which is then directed into the turbine through the throttle valve. Steam exiting the turbine is passed through a condenser with twin engine powered cooling fans.
