| 摘要 |
The airflow distribution of bleed air extracted from a plurality of turbine engines (11, 13, 15, 17) is equalized by an airflow sharing system having electronic airflow sensors (49, 51, 53, 55) and closed-loop control algorithm to equalize the pressure-drop characteristics of multiple bleed air branches to flow-share equally. The pressure-drop characteristic of each airflow branch is controlled to the same setpoint characteristic by negative feedback. The closed-loop control can be implemented with an electronic circuit or as a computational process in a digital controller. |
