MT 551 TURBO JET ENGINE, 70N Thrust, Computer Interface




The engine is a small turbo jet engine and modified for educational purposes. The unit has 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 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 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.

An engine cover and over speed shutdown are provided.

Instruction manual is also included.
