Turbo Jet Engine, 40N Thrust
OSC77FD550MT
Features
-The engine is a bench top unit for a small turbo jet engine and modified for educational purpose-The unit has a radial flow compressor and an axial flow turbine as in the modern aviation industry
-Inlet air through an orifice flow measuring device is compressed by a single stage radial flow compressor
-The turbine is started by Liquefied Petroleum Gas (LPG) and run by Jet A fuel
-Fuel is injected and ignited in the combustion chamber providing hot gas for a single stage axial flow turbine
-The gas is exhausted through a nozzle at high velocity providing a thrust
-The turbine unit is complete with automatic front motor start, and runs on ceramic bearings
-Lubirication is provided by jet oil in the fuel, and no separate lubrication system is required
-An Electronic Control Unit (ECU) controls the basic turbine operation
-Additional instruments are provided for monitoring and controlling engine operation and performance
-For safety reason, an over speed sensor and steel bars aroung the compressor and turbine sections are provided
