A gas turbine powerplant simulator arrangement includes an engine body 2, an intake 13 and exhaust nozzles 3, 4. An air intake flow duct 12 extends from the air intake 13. There is a first primary injector 7, 7a adjacent the intake 13 and includes a primary drive gas inlet 15 connectible to a gas supply source. The flow duct 12 includes an excess flow discharge duct 27 and a balance flow passageway 19a communicating a second primary injector 9 located intermediate the air intake 13 and the adjacent exhaust nozzle 3. The second injector 9 includes its own primary drive gas inlet 28 connectible to an independent gas supply source. The injectors 7, 7a and 9 extend across the full flow cross-section of the duct 12.
