DEVELOPMENT OF EXPERIMENTAL SOLID STATE ENGINE INSTRUMENT DISPLAYS.
Abstract
The design and fabrication of a versatile set of solid state display components usable in engine instrument display configurations are described. The effort resulted in the development of plug-in electroluminescent display panels, each consisting of six columns of 125 elements at 25 lines per inch, plus scales and legends. The displays are hermetically sealed and are green or yellow, or a combination of green and yellow. Each column is controlled by a seven bit parallel binary word. Nine display panels, three sets of logic and switching electronics, an intensity control unit, and plastic overlay scales and legends were fabricated. These components may be arranged to simultaneously display the engine parameters of revolutions per minute (RPM), exhaust gas temperature (EGT), and engine pressure ratio (EPR) for a six engine VTOL aircraft.
