4008 Characterization of High Power Diode Laser Module System for Thermal Evaluation of Space Structures
Details
In order to evaluate thermal behaviors of the composite materials for usage to nozzles of solid rocket motor and thermal protection system of re-entry space vehicle, a high power diode laser module system, with two scanning mirrors, was developed for high heat source. As direct measuring of heat flux of laser heating is not effective, a weight loss measurement of PMMA plate method was proposed and evaluated. The scanning patterns of mirrors with galvanometric type scanner were characterized for a uniform heating capability.
