Flight assured.

ASE FluiDyne aerodynamic testing services helps advance new benchmarks for turbine engine exhaust system and thrust reverser performance for advanced business jet applications including supersonic flight.

Channels 11 and 14 combine the conventional static test stand direct force measurement system with the added capability of running hot and cold flow simultaneously with the hot (900 degrees F) flow duct enabling the simulation of the temperature ratio between the core stage and bypass stage of an engine exhaust system. The effects of the mixing of hot primary and cold secondary streams on nozzle performance can be studied in these facilities. These facilities also feature three component force balances which define the thrust vector for asymmetric exhaust nozzle configurations. Surface and stream pressures and temperatures can be measured together with force, and many of the special techniques applied in ASE’s cold flow static stands can be applied here also. The Channel 11 facility is also configured to acquire comparative acoustic data on candidate nozzle configurations to aid in selecting the best thrust efficiency/noise combination.
