Aircraft ice protection control system and method for mitigating engine over-bleed |
摘要 |
A system and method for controlling aircraft anti-ice bleed air flow in an anti-ice system. The system includes a modulating shut-off valve that is moveable between a closed position and a plurality of open positions. Bleed air pressure upstream of the modulating shut-off valve is measured when the modulating shut-off valve is in the closed position. When an anti-ice initiation signal is received in a processor, the processor determines, based on at least the measured bleed air pressure when the anti-ice initiation signal was received, an initial open position of the modulating shut-off valve. The processor also commands the modulating shut-off valve to move to the initial open position, determines when a predetermined event occurs, and commands the modulating shut-off valve to remain in the initial open position until the predetermined event occurs period. |

1. A method of controlling aircraft anti-ice bleed air flow in an anti-ice system comprising a modulating shut-off valve that is moveable between a closed position and a plurality of open positions, the method comprising the steps of:
measuring, when the modulating shut-off valve is in the closed position, bleed air pressure upstream of the modulating shut-off valve; receiving, in a processor, an anti-ice initiation signal; and using the processor to:
determine, based on at least the measured bleed air pressure when the anti-ice initiation signal was received, an initial open position of the modulating shut-off valve,command the modulating shut-off valve to move to the initial open position,determine when a predetermined event occurs, andcommand the modulating shut-off valve to remain in the initial open position until the predetermined event occurs period. |
