The report summarizes the results of a 30-month program of design, fabrication, and test of an advanced electronic engine control system for small turboshaft engines. The objective of the program was to develop engine control system technology which could be implemented in future systems to alleviate many of the problems experienced with past and present control systems. The system is comprised of three modules a fuel-cooled hybrid electronic computer, a fluid controller with integral 37,500-rpm pump, and a remote electrohydromechanical engine geometry actuator. Closed-loop tests were made to demonstrate the control system performance on both a 2- and a 5-lbsec analog computer engine simulator. Environmental temperature endurance testing and fuel contamination testing were completed.
