| Abstract: |
| An integrated flight/propulsion control algorithm offers significant performance improvements using Linear Programming to compute a set of adjustments to the normal control settings. The integrated flight/propulsion control system is developed, and is used in simulation of hardware-in-loop with the two optimization modes: maximum thrust mode and minimum fuel consumption mode. Test results presented here demonstrate that during accelerating flight at constant altitude thrust increases up to approximately 9 percent in the maximum thrust mode, and at subsonic cruise specific fuel consumption decreases up to 1.5 percent in the minimum fuel consumption mode. |
