The turbine is a small two-shaft gas turbine engine with a radial flow compressor and axial flow turbines as in modern air plane.

The first shaft is a gas generator. Inlet air through an orifice flow measuring device is compressed  by a single stage radial flow compressor. The turbine is motor started and runs on Jet A fuel. Fuel is injected by a fuel pump and ignited in the combustion chamber providing hot gas for a single stage axial flow turbine which inturn drives the compressor. The hot gas is discharged axially to a larger power turbine on the second shaft and exhausts to atmosphere The gas generator unit runs on ceramic bearings. A fan is provided for cooling the engine.

Speed of the power turbine is reduced by the gear box. An eddy current absorber is connected to the gear box for power measurement. Load is manually controlled.

An Electronic Control Unit (ECU) controls the basic turbine operation. Additional instruments are provided for monitoring and controlling turbine performance.

A touch screen computer with an interface unit, and software are provided for speed and load control, data display and analysis, and to assist the ECU.

Safety features include clear acrylic cover, gas generator or power turbine over speed and power turbine entry over temperature shutdown.

The unit is floor standing with removeable supports.
