Quiet Clean Short-Haul Experimental Engine (QCSEE) under-the-Wing Engine Digital Control System Design Report

摘要

A digital electronic control was combined with conventional hydromechanical components to operate the four controlled variables on the under-the-wing engine: fuel flow, fan blade pitch, fan exhaust area, and core compressor stator angles. The engine and control combination offers improvements in noise, pollution, thrust response, operational monitoring, and pilot workload relative to current engines.
