Description The Reaction Turbine Module F300D turbine is a single stage, radialflow, two jet reaction machine, operating on air, specially designed andmanufactured by Limited for experimental and teachingpurposes. With a throttle valve and belt brake dynamometer, inlet andoutlet air temperatures are recorded allowing the temperature drop dueto work output to be measured. The turbine rotor is carried on a steelshaft running in oil lubricated ball bearings. Compressed air, deliveredto the rotor through a central duct provided with a face seal, passes intothe rotor and then moves radially to convergent nozzles formed in theperiphery. The resulting high velocity jet leaving the rotor and themomentum changes associated with the air movement produces aREACTION which drives the rotor and produces a shaft power output.The turbine rotor is housed within a thick walled stainless steel exhaustcasing and air from this passes to the atmosphere via a flow meter. Inletand outlet air pressures, temperatures and air flow rate, turbine torqueand speed are recorded by a combination of instrumentation on theCompressible Flow Range F300 base unit and the optional module Technical Specification 2 x Thermocouples 10N Load Cell maximum capacity Turbine Speed: 35,000 rpm (continuous) Turbine Speed: 40,000 rpm (short periods only) Pressure Relief valve setting: 100kN/m2.
