Abstract
An apparatus for aircraft anti-icing includes a nozzle body, a nozzle extending from the nozzle body, an eductor shroud at least partially surrounding the nozzle, the eductor shroud configured to focus a first flow of ambient air towards a first flow of hot gas exiting the first nozzle.
Claims20
An apparatus for aircraft anti-icing, the apparatus comprising:
- a nozzle body;
- a first nozzle extending from the nozzle body;
- and
- a first eductor shroud at least partially surrounding the first nozzle, the first eductor shroud configured to focus a first flow of ambient air towards a first flow of hot gas exiting the first nozzle.
1 more element
An aircraft anti-icing system comprising:
- a source of a hot gas;
- a housing;
- a conduit configured to carry the hot gas from the source to the housing;
- and
- an outlet nozzle coupled to the conduit, the outlet nozzle comprising:
- a nozzle body;
- a first nozzle extending from the nozzle body;
- and
- a first eductor shroud at least partially surrounding the first nozzle, the first eductor shroud configured to focus a first flow of ambient air towards a first flow of hot gas exiting the first nozzle.
6 more elements
A method for preventing formation of ice, the method comprising:
- receiving, at an outlet nozzle, a hot gas from a compression stage of an engine;
- and
- conducting, via the outlet nozzle, the hot gas received from the compression stage to an internal volume of a leading edge housing, wherein the outlet nozzle conducts the hot gas based on a flow pattern, wherein the flow pattern is determined based, at least in part, on a geometry of the outlet nozzle that has a nozzle body, a first nozzle extending from the nozzle body, and a first eductor shroud at least partially surrounding the first nozzle, the first eductor shroud configured to focus a first flow of ambient air towards a first flow of hot gas exiting the first nozzle.
