Applications of Fluidics to Light Aircraft Instrumentation and Control 740351

This paper reviews NASA/Langley's program for the development of advanced fluidic components and the application of these components to general aviation instrumentation and control. The major project in this category has been the development of a simple, reliable, two-axis autopilot for light aircraft, using a fluidic inertial rate sensor for stability and roll attitude control, and a simple magnetometer for azimuth reference. This autopilot has been successfully flight tested. Fluidic hardware developed for this autopilot is described, and projected improvements and extensions are discussed. Application of fluidic components to such flight instruments as turn coordinators, artificial horizons, and true airspeed indicators is explored.
