An Object-Oriented Graphical User Interface for a Reusable Rocket Engine Intelligent Control System.

Abstract

An Intelligent Control System for Reusable Rocket Engines under development at NASA Lewis Research Center requires a graphical user interface to allow observation of the closed-loop system in operation. The simulation testbed consists of a real-time engine simulation computer, a controls computer, and several auxiliary computers for diagnostics and coordination. The system is set up so that the simulation computer could be replaced by the real engine and the change would be transparent to the control system. Because of the hard real-time requirement of the control computer, putting a graphical user interface on it was not an option. Thus, a separate computer used strictly for the graphical user interface was war- ranted. An object-oriented LiSP-based graphical user interface has been developed on a Texas Instruments Explorer 11+ to indicate the condition of the engine to the observer through plots, animation, interactive graphics, and text.
