TURBO JET ENGINE, 70N Thrust.
GENERAL DESCRIPTION
The engine is a bench top unit for a small turbo jet engine with a radial flow compressor and an axial flow turbine as in modern jet plane.
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 and ignited in the combustion chamber providing hot gas for a single stage axial flow turbine which inturn drives the compressor. The gas is exhausted through a nozzle at high velocity providing a thrust. The turbine unit runs on ceramic bearings. Lubrication is provided by jet oil in the fuel, and no separate lubrication system is required. A fan is provided for engine cooling.
An Electronic Control Unit (ECU) controls the basic turbine operation. Additional instruments are provided for monitoring and controlling engine operation and performance.
A touch screen computer with an interface unit, and software are provided for speed control, data display and analysis, and to assist the ECU.
A transparent engine cover, and over speed shutdown are provided.
