An investigation was made of several ways of simultaneously simulating the external pressure field generated by an engine exhaust jet and an air inlet. The techniques investigated used high-pressure air piped up¬stream through the simulated jet to the exhaust nozzle of the engine. It was then discharged through perforations in the pipe or in a downstream direction through a target-type reverser at the end of the pipe. This air combined with the engine-inlet air to form a jet contour. The tests were made at free-stream Mach numbers of 2.5 and 3.0 for a range of jet-exit static-pressure ratios from 1.0 to 3.0.
