초록

A gas turbine engine bleed air system in which air flow from a high pressure and a low pressure compressor stage of a gas turbine engine are mixed together by controlling the pressure at the outlet of a proportional valve. The pressure is controlled by modulating the flow area of the proportional valve through which the high pressure air flows in order to achieve a scheduled pressure value. The scheduled pressure value is determined as a function of a temperature error at a location downstream of the proportional valve in the bleed air system.

청구항

A bleed air system for receiving high pressure and low pressure compressed air from a gas turbine engine to provide a temperature regulated flow of mixed bleed air substantially equal to a desired mixed air temperature value at the output of a mixing conduit, comprising: first means, for mixing in the mixing conduit, the low pressure compressed air with a modulated flow of high pressure compressed air provided by a proportional valve, said proportional valve modulating the flow of high pressure air in response to a valve area command signal; means for pr...
