Abstract:

The variation in absolute temperature present in the exhaust plume of a statically fire CRV-7 rocket motor is reported. The temperatures were recorded using a infrared radiometer, a device which uses an infrared camera to capture images of the plume. A camera technique avoids the need to place a measuring device, such as a thermocouple, into the plume which in turn alters the state of the plume. The apparent temperatures present in the plume are measured from the plumes infrared radiation signature. These apparent temperatures are converted to true temperatures by comparison with those recorded using a thermocouple in a number of calibration firings. The results reported provided representative information on the temperature profiles present in the CRV-7 rocket motor plume.
