High-Temperature Jet Facility (HotJet)

A facility capable of producing high-temperature, high-speed airflow is essential to accurately simulate the exhaust from a jet engine. The High-Temperature Jet Facility at FSU's Florida Center for Advanced Aero-Propulsion laboratories has opened the door to numerous research opportunities for the study of both free and impinging jet flow. This blow-down type facility is supplied by six compressed air storage tanks and employs a sudden expansion ethylene burner to generate jets of air at temperatures of up to 2200°F and ideally expanded jets at speeds beyond Mach 2.5. Single and multiple nozzles of various geometry can be easily implemented and the integration of supplementary airflow subsystems permits investigations of various co/counter-flow configurations. The jet exhausts into a fully anechoic chamber providing the means to accurately perform a multitude of aeroacoustic studies.
