SECTION 2. SYSTEMS

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

Figure 3: 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.

The breakers on the switch panel are:

  • Ignitor - Protects the ignitor circuit from overload.
  • Fuel Gauge -
  • Instruments -
  • Landing Lights -
  • Dynamo -
  • Radio -
