This report documents a program which demonstrated the feasibility of using a Bendix Model EH-K1 digital controller to operate the gas generator portion of a Joint Technology Demonstrator engine. The control modes were developed by Detroit Diesel Allison, Division of GMC, to achieve optimal specific fuel consumption and safe engine operation. A digital simulation of the control modes was interfaced with a digital simulation of the engine to determine schedules and compensation. The Energy Controls Division of Bendix Corporation, as subcontractor to Detroit Diesel Allison, then coded the control modes to be compatible with the EH-K1 instruction set. The software was tested on a ground-based version of the EH-K1 interfaced to a simplified, linear analog engine model. The testing demonstrated stable engine operation using the defined control modes. Author
