Abstract
A bleed system including control circuitry and a variable jet pump. The control circuitry is configured to receive a signal indicative of a fluid parameter in the bleed system and cause the jet pump to alter a mixing ratio of a higher pressure gas and a lower pressure gas based on the signal. The jet pump is configured to combine the lower pressure gas and the higher pressure gas in the mixing ratio to generate a mixed gas. The jet pump is configured to supply the mixed gas to one or more gas loads in the bleed system. In examples, the control circuitry is configured to establish a system setpoint for the fluid parameter based on an operating status of the one or more gas loads.

- wherein the jet pump is configured to alter a mixing ratio of the higher pressure gas to the lower pressure gas combined when the jet pump produces the mixed gas,
- wherein the jet pump is configured to supply the mixed gas to a plurality of gas loads;
- and
- a control circuitry configured to receive a signal indicative of a fluid parameter of the mixed gas, wherein the control circuitry is configured to:
- receive a plurality of load signals from the plurality of gas loads, wherein a load signal in the plurality of load signals is indicative of an operating status of a gas load in the plurality of gas loads,
- determine a setpoint for the fluid parameter using the operating status indicated by the plurality of load signals,
- compare the fluid parameter indicated by the signal with the setpoint, and
- cause the jet pump to alter the mixing ratio based on the comparison of the fluid parameter and the setpoint.
A system, comprising:
- a jet pump configured to receive a lower pressure gas from a lower pressure stage of a turbine engine and receive a higher pressure gas from a higher pressure stage of the turbine engine;
- wherein the jet pump is configured to combine the lower pressure gas and the higher pressure gas to produce a mixed gas,
- wherein the jet pump is configured to alter a mixing ratio of the higher pressure gas to the lower pressure gas combined when the jet pump produces the mixed gas, and
