Reaction turbine: Investigation of a compressed air driven radial reaction turbine.

Features

• characteristic behaviour of a reaction turbine with air flow, optimal view of the operating area of a turbine, load applied by band brake.

• Learning objectives/experiments, familiarisation with the design and function of an impulse turbine, determination of torque, power and efficiency, graphical representation of characteristic curves for torque, power and efficiency.

Specification

• investigation of a compressed air driven radial reaction turbine

• transparent housing for observing the operating area

• rotor with 4 outlet nozzles

• application of load to the turbine by means of a band brake

• setting of the primary pressure with the pressure reducing valve
