Contents
1 Helicopter
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.
1.2 Gross Weight
The maximum gross weight is 2,100 pounds.

1.5 Switch Panel
A switch panel is located at the bottom of the instrument panel and contains the majority of the switches and breakers in the aircraft. Left to right the switches are:
- Ignitor - Key switch that turns on the ignitors for the burner. Requires that electrical power be active as well.
- Batt. (Master) - Main electrical power from the battery.
- Dynamo (Master) - Main electrical power from the dynamo. The dynamo is powered when the engine RPM is at least 50%.
- Aux Fuel Pump - Provides fuel pressure to the burner via an electrically driven pump
- Feed Pump - Pumps water from the reservoir to the boiler.
- Inst. Lights - Provides light for the cabin from two lights mounted on the back wall.
- Nav. Lights - Powers the three navigation lights, right on the left, blue-green on the right and white on the tail.
1.6 Magnetic Compass
A magnetic compass is mounted on top of the main instrument panel. Note that the magnetic compass is only accurate in straight and level flight and is subject to the following types of error:
- Oscillation - Turbulence and motion of the aircraft will cause the compass reading to oscillate. The more steady the aircraft is held in a level attitude, the more accurate the reading will be.
- Deviation - Magnetic fields generated by the aircraft itself can affect the compass reading. A compass card (<xr id="fig:pilotPanel"> (#2)) on the main panel provides corrections from indicated headings to actual headings.
