Sickle cell anemia is an inherited disorder of erythrocytes characterized by chronic anemia, recurrent pain, susceptibility to infections, chronic and recurrent organ dysfunction, and diminished life-expectancy. Even among patients having documented homozygous sickle cell anemia (Hb SS), there exists an astonishing degree of variability in clinical severity. Some die from strokes as young children ...

An innovative actively cooled structure concept is proposed which integrates proven cooling techniques and state-0f-the-art fabrication methods to extend the maximum combustor wall temperature, thereby reducing cooling requirements and aircraft weight while improving engine performance. Specifically, CONvective and TRANspiration cooling(CONTRAN) are uniquely combined, relying on hydrogen coolant t ...

A completely new approach is proposed for the accurate measurement and display of the true airspeed of helicopters in hover, low-speed and forward flight. Unlike conventional instruments, the proposed innovation will be characterized by high-frequency response and high sensitivity across the range of helicopter flight speeds. The proposed device will provide accurate speed indication both at low a ...

The new aerospace materials are finding applications in the design of military armor vehicles. However, the effect on ride quality, fire control, and internal structural loads due to the increased flexibility of these new vehicles must be ascertained by dynamic analysis. The size of models required to simulate these flexible body effect can be prohibitive from both cost and time perspective. There ...
