Continued studies have been undertaken to investigate and develop aerodynamic models that predict aircraft response in nonlinear unsteady flight regimes for transport configurations. The models retain conventional static and dynamic terms but replace conventional acceleration terms with indicial functions. In the Subsonic Fixed Wing Project of the NASA Fundamental Aeronautics Program and the In...

This document describes the progress we have made and the lessons we have learned in 1999 under the NASA Grant NAG2-1230 entitled \Application-Speci c Supercomputing". The long-term goal of this research is to accelerate large, irregular scienti c applications which have enormous data sets and which are di cult to parallelize. To accomplish this goal, we are exploring two complementary techniqu...

T HERE ARE MANY considerations in the selection of the gaseous environment for a manned spacecraft. Generally, these can be divided into two categories; engineering considerations and physiologic considerations. Ideally, the optimum spacecraft atmosphere, from a physiologic point of view, would be one which simulated normal or near normal sea level conditions. Since the present state-of-the-art...
