Abstract

A bleed air control system and method include first and second flow paths, first and second flow control valves, and a controller. The first flow path is configured to carry a first bleed air flow and includes a heat transfer device configured to transfer heat to or from the first bleed air flow. The second flow path is configured to carry a second bleed air flow. The first and second flow paths merge downstream to provide a combined bleed air flow. The first flow control valve is positioned to control the first bleed air flow, and the second flow control valve is positioned to control the second bleed air flow. The controller is configured to control the first and second flow control valves to control a temperature and flow of the combined bleed air flow.
