Abstract: An assembly is provided for an aircraft propulsion system. The assembly includes a nacelle inlet structure with an internal cavity. The assembly also includes a nozzle configured to direct fluid into the internal cavity through a plurality of ports that include one or more first ports and at least one second port. The nozzle includes a trunk conduit, a first branch conduit and a second branch conduit. The first branch conduit and the second branch conduit are fluidly coupled in parallel to the trunk conduit. The first branch conduit includes the first port(s). The second branch conduit includes the second port.

Abstract: An injector head for an anti-icing system may comprise a body configured to receive a pressurized gas, wherein the body is configured to provide the pressurized gas through a bulkhead into an interior volume of a D-duct, a first nozzle configured to generate a first flow of a first portion of the pressurized gas, a second nozzle configured to generate a second flow of a second portion of the pressurized gas, and a third nozzle configured to generate a third flow of a third portion of the pressurized gas, wherein the first nozzle is located at a distal end of the body relative to the bulkhead, and wherein a first hydraulic diameter of the first nozzle is less than each of a second hydraulic diameter of the second nozzle and a third hydraulic diameter of the third nozzle.
