This SAE Aerospace Information Report (AIR) presents a review of the types and general characteristics of power sources that may be used to provide the power for gaseous or liquid fluidic control systems. Fluidic definitions, terminology, units and symbols are defined in reference 2.11.

Field of Application:

The power systems described and the data contained herein apply to all types of aerospace vehicles including: aircraft, helicopters, missiles,. Space vehicles, remotely piloted vehicles, or in any other vehicles or applications to which aerospace technology applies.


Fluidics is a control technology that relies on the interaction of fluid (liquid of gaseous) streams to provide sensing, amplification, filtering, signal conditioning, and other control functions. Pure fluidics employees no moving-part devices, but most operational fluidic systems employ some moving-part peripheral elements such as linear and rotary motion sensors, valves, actuators, switches, push buttons, and other devices that provide inputs to and outputs from the fluidic elements in the system.


The information in this document is intended to be used as guidelines in the selection of power sources most appropriate to the requirements and characteristics of a particular vehicle or system. It may also be used verbatim or as a guideline in the preparation of system or power source specifications. Considerations, problem areas and benefits of the various power sources and configurations are presented in order to assist in conducting trade studies and evaluations.

More detailed information on fluidic control technology, fluidic test methods and instrumentation, and power sources for other applications is available in SAE AIRs and in SAE ARPs. These and other references are all listed in section 2.
