Advanced Fluidic Controls for Integrated Propulsion Systems. Part 4. Demonstration of an Integrated Propulsion System Control at Simulated Flight Conditions Using Fluidic Control Techniques

摘要

Feasibility of a fluidic control system for advanced integrated propulsion system control was demonstrated at simulated flight conditions in an altitude engine test cell. System studies were conducted using control and engine computer simulations to develop advanced propulsion system control modes. Using fluidic sensors and computational elements developed under this program, a fluidic integrated propulsion control system was mechanized and evaluated on a J95-GE-5 engine at the Air Force Aero Propulsion Laboratory at simulated Mach numbers and altitudes. Performance capability was demonstrated in the areas of start up, speed control, transient control, compressor stability control, turbine overtemperature control, overspeed control and variable engine geometry control.
