Advances in anti-G valve technology: what's in the future?

Conventional mechanical anti-G valve technology has been overtaken by the performance of modern aircraft and will fall farther behind in new generations of fighters. This paper discusses the fundamental shortcomings of anti-G valves and presents concepts and enhancements potentially available with recently developed servovalves, concepts now under active investigation and development, and closes with an overview of advanced anti-G suit concepts compatible with advanced adaptive servovalves.
