Centrifuges for studying the effects of sustained acceleration on human physiology.

The operation, development, and use of high-performance centrifuges with high G-onset rates, similar to those found in modern fighter aircraft, are discussed. Their performance characteristics are examined, and the USAFSAM centrifuge at Brooks AFB in Texas is then described. Centrifuges for space research and large-radius track centrifuges are considered. The benefits of the latter are discussed.
