Abstract

Transient measurements in fluid flows are required when the flows are generated by an impulse device such as a shock tube. In our laboratory, a shock tube is used to generate simulated rocket plumes which are investigated for the development/validation of plume signature codes. This paper describes progress in the implementation and use of a PtSi camera to obtain radiometric data in test time periods that are less than conventional frame rates for such devices. Optical modifications and implementation of the camera as an absolute radiometric detector are presented. Overall camera performance in terms of system noise and dynamic range is assessed, and sample plume images in the H2O band centered at 2.8 microns are shown. Future system improvements and measurement program capabilities are mentioned.
