ABSTRACT:
The test cell has a pressure recovery pipe (26) receiving air from the tested engine (14). Excess air is inherently induced into the pipe. A source flow path for this excess air is provided from within the pipe (36) back to the entrance the pipe passing through a perforated bulkhead (30). High local velocities of the recirculating air, resulting variable static pressures on the engine and uncertainty in the thrust measurement are avoided.
