Shock Tube Experiments for Earth and Mars Entry Conditions.

摘要

This seminar describes how radiative heating for earth and Mars entry conditions has been studied using the Electric Arc Shock Tube (EAST) at the NASA Ames Research Center in California. The motivation for these studies includes directly assessing the radiative heating to be expected in specific missions and the improvement of modeling codes used to predict entry heating. The facility and its instrumentation are described. The techniques used for the spectrally resolving instruments are described in some detail. Facility operating procedures and spectrograph and monochromator calibration techniques are described. Representative data is presented from the data acquisition system and representative spectra are presented for earth and Mars entry conditions.
