Results of Testing the AEDC 5-MW Segmented ARC Heater at Pressures up to 171 ATM

The results of testing a nominal 5-MW segmented (constrictor-channel type) arc heater are presented. The heater was operated at chamber pressures up to 171 atm and power inputs to nearly 4 MW using air as the test gas. The nozzle exit flow was surveyed with a null-point calorimeter, pressure, and en...

Zusammenfassung:The results of testing a nominal 5-MW segmented (constrictor-channel type) arc heater are presented. The heater was operated at chamber pressures up to 171 atm and power inputs to nearly 4 MW using air as the test gas. The nozzle exit flow was surveyed with a null-point calorimeter, pressure, and enthalpy probes. Performance comparisons are made between the segmented and other types of arc heaters and with an analytical correlation program. Detailed test and data summaries are presented. See also AD-A002 313.
