Description

The C1-MkIII equipment comprises a single-stage air compressor, complete with a test section and a throttling valve, plus an electronics
console containing the necessary controls and instrumentation.
The single-stage compressor is driven by an integral three-phase ACmotor. 

The compressor speed can be varied using an advanced torquevector frequency inverter, which gives stable and accurate speed control
plus direct electronic read-out of the torque produced by the motor.
The compressor is ftted with an outlet duct incorporating a throttling valve, which allows the ?ow to be varied independent from compressor speed.
The equipment is supplied with a convergent-divergent test section, ftted at the compressor inlet, designed to produce Mach-1 velocity at
the throat. The duct is fabricated from clear acrylic, enabling the student to see the construction and the profles. A pressure-sensing ring tapping
is provided at the inlet, at the throat and at the discharge end of the di?user. This duct allows all the major concepts of compressible ?ow to
be demonstrated.
The electronics console includes two high-range and two low-range di?erential pressure sensors plus a control for motor speed and displays
for the compressor speed, the pressures and the motor torque.
