GMA200 ATEGG Digital Controls Demonstration.

Abstract

This report describes the results of the closed-loop, on engine test of the Bendix EH-K1 digital controller on Build 5 of the Advanced Technology Engine Gas Generator (ATEGG). Control modes are described with emphasis on changes to be incorporated on ATEGG Build 6. The control mode changes include simplification of the fuel governor structure, modification of the fuel splitter logic to aid main fuel system light-off, and modification of the fuel limiting logic to prevent transient overshoots of critical engine parameters. Off-engine testing of the controller with the ATEGG fuel system is discussed. Fuel system characteristics were analyzed and adjusted to yield tighter control of engine fuel flow. The Build 5 test stand set-up and instrumentation are described, along with testing accomplished and data correlation. The open loop operation of the controller was successfully demonstrated, and data correlation with test stand values was satisfactory. Successful closed loop digital control operation was exercised at the end of Build 5 engine testing. (Author)
