The high-speed jet facility at the University of Bristol is an ideal infrastructure for fundamental and industrial high-speed investigations, including jet aerodynamics, jet noise, jet installation effects, flow instability, etc. The air supplied by three separate compressors, providing over 500 liters per second of compressed air, enables to obtain a jet flow at Mach numbers in the range between 0.1 and 1.4. A range of nozzles with different diameters (1cm to 5cm) and different lip geometries (straight, chevron, elliptic, scarfed, etc) are available. The jet facility can be placed in the UoB anechoic chamber and its flow rate can be controlled using an electronic flow regulator. Three large pressure-vessel silencers are placed after the flow regulator to remove any noise from the compressor and the flow regulator, before the flow enters the anechoic chamber. The jet test-rig is made such that the nozzle can be changed readily for studies involving different nozzle configurations. The facility also has the capability to carry out jet noise studies in the presence of flight stream. The facility can deliver a flight stream velocity of 120 knots (61 m/s), with a circular flight-stream nozzle with a diameter of 60cm. The anechoic chamber is equipped with 50 free-field microphones located 1.7m from the jet nozzle, covering polar angles from 30 degrees to 150 degrees.

In addition to the high-speed jet facility, a range of low-speed jet flow test rigs have also been designed and manufactured for studying flow dynamics and instabilities at low speeds (below 100m/s). These stand-alone jet test rigs consist of a centrifugal fan, a labyrinth silencer, and a range of circular and rectangular nozzles.
