Function:
Laboratorysized Impulse Turbine unit
Determination of power as a function of volumetric flow rate, pressure and speed
Recording of torque characteristic
Determination of the turbine efficiency
Study of the influence of the air flow rate on the power  
Study of the influence of the number of nozzle used  
Cycle Plotting on diagram TS (entropie temperature)  
Partial pressurization (nozzle group circuit)

Turbine: 
Turbine single stage with axial flux ; Maximum speed: 35000tr/min; Max power: 45W  
Injection nozzles: four nozzles with isolation valves.  
Brake: brake with belt mounted on the shaft of the turbine. The cooling is assured by a compressed air supply  
Torque meter: force sensor with strain gauge and indicator on the panel  
Temperature: Measurement of the air inlet and outlet of the turbine by probe Pt 100 three wires  
Air flowrate: float flowmeter with glass tube at the turbine outlet   

Rotation speed: optical sensor with npn converter  
Pressure manometer: manometer with bourdon tube scale of 1 to +1 bar  
Safety valve: prevents the overpressures in the turbine  
Filter regulator: purifies the compressed air supplying the machine and reduces the pressure  
Needle: ensures the adjustment of the tension of the belt of the brake of the turbine   
Compressed air supply: 68 bars (dry air)
