Research in materials processing using a low gravity simulation aircraft

The feasibility of performing materials experiments aboard the NASA KC-135 low gravity simulation aircraft is demonstrated. The vehicle serves as a research platform which flies parabolic maneuvers. Experiments which have been conducted on board the aircraft are outlined and particular attention is given to tests utilizing optical measurement techniques such as interferometry, schlieren, and holography. It is noted that the KC-135 can be used for crew training, flight hardware checkout, conceptual development, self-sufficient experiments, and research in support of and leading to space flight experiments.
