| Outline of Final Research Achievements |
An existing shock tube facility has been modified into an expansion tube, in which atmospheric entry conditions for Mars exploration can be realized around test models. In addition, an instantaneous infrared spectroscopy system has been developed by using an infrared CCD camera having a gating function. Above all, an infrared spectroscopic measurement system for Martian atmospheric entry systems, which is the only facility in the nation, has been developed, and the world’s first results of infrared spectra distribution around a Martian entry capsule have been obtained successfully. Based on the experimental results, the world’s most accurate database for infrared CO2 radiation has been developed. Using this improved database, accuracy of the radiation prediction code is successfully improved from the past value of 50% into 90%, which is currently the world’s greatest.
