Turbo Jet Engine – 70N Thrust
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 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 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.
Instruction manual is also included.

Air Flow and Thermodynamics
Two-Shaft Gas Turbine
The turbine is a small two-shaft gas turbine engine with a radial flow compressor and axial flow turbines as in the modern gas turbine power plant.
The first shaft is a hot 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. A fan is provided for cooling the gear box.
Speed of the power turbine is reduced by the gear box. A water brake absorber is connected to the gear box for power measurement. The brake requires outside water supply. 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 over speed shutdown, power turbine over speed protection and power turbine entry over temperature shut down. The unit is floor standing with removeable supports.
Instruction manual is also included.

Water Hammer Apparatus
This apparatus is used to study the effects of both pipe surge and water hammer using two separate straight pipes with a constant head tank.
Pipe surge employs a clear acrylic surge shaft to demonstrate gradual velocity change, hence pressure rise and its oscillations by slow valve closing. Water hammer employs a quick closing valve and two pressure sensors-one next to the valve and another further away. Sudden rise in pressure on quick closing valve can be demonstrated on a computer (separately supplied). The equipment is to be used with Hydraulics Bench (separately supplied).
Instruction manual is also included.
TYPICAL EXPERIMENTS- Pipe surge and oscillations in surge shaft.
- Friction loss between head tank and surge shaft.
- Pressure profiles for water hammer and comparison with theoretical values.
- Determination of the velocity of sound through a fluid in a pipe.
