The determination of aerodynamic coefficients for complex high-speed vehicles still requires experimental measurement. This paper details the development free-flight measurement technique within University Oxford High Density Tunnel. In particular, a novel image processing is developed calculating position model from video. study focuses on high Reynolds number data subscale Skylon space plane ...

A key factor limiting long-duration space flight is the inability to maintain the crew effectively in weightlessness. Current approaches to crew preservation involve discrete experiments to measure physiologic adaptation and post flight evaluations to assess the effectiveness of countermeasures. As the length and complexity of missions increase, these approaches will be inadequate. A revolution...

The paper reviews the National Aeronautical and Space Administration’s (NASA) research program, flight experiments and flight application related to Adaptive Structures. Emphasis is on results from both experimental and flight hardware test programs that helps validates its theoretical performance. The paper includes the role of Adaptive Structures to meet NASA’s current and future technology a...

This paper reviews the interventions to stabilize calcium balance and bone metabolism and prevent bone loss in astronauts during space flight. Weightlessness during space flight results in calcium, vitamin D, and vitamin K deficiency, increases urinary calcium excretion, decreases intestinal calcium absorption, and increases serum calcium level, with decreased levels of serum parathyroid hormon...

Beginning in the mid-1980s, the phenomenon of capital flight from developing countries received considerable attention in the economics literature. Capital flight destroys the domestic macroeconomic environment and decreases transparency and accountability. It restricts financial resources when a country is looking for economic growth and development. The purpose of this article is to measure t...
