Fluid amplifier state of the art. volume i- research and development - fluid amplifiers and logic

The report surveys the current state-of-the-art of fluid amplifiers
including both theoretical and practical aspects of devices having no mechanically moving parts.

It is based on a complete review of the published literature
(with an extensive bibliography), information obtained from 20 organizations
involved in fluid amplifier development, and work performed by the General
Electric Company.

Specific areas covered are design techniques, both analytical
and experimental; typical elements and assemblies; applications, both now
in use and contemplated; fabrication techniques; and instrumentation.

The report concludes that, although simple applications are now
being made, the fluid amplifier field is still in the early development stage.
There continues to be a basis for optimism for space applications requiring
extreme environmental tolerance, long life, or the elimination of fluid system interfaces. Specialized military, and commercial applications also look
promising. Work now under way should provide a better understanding of the design of devices and increase the number of useful applications.
