Abstract
A RAM inlet header (RIH) is provided and includes a body through which RAM air flows from an inlet toward a heat exchanger and a nozzle body arranged along a wall of the body to direct a curtain of cooled air into flows of the RAM air and toward the heat exchanger.
Claims18
A RAM inlet header (RIH), comprising:
- a body through which RAM air flows from an inlet toward a heat exchanger;
- a nozzle body arranged along a wall of the body to be extendable into and retractable from an interior of the body,
- the nozzle body being configured to exclusively form a curtain of cooled air along and at the wall when extended into the interior and to thereby direct the curtain of cooled air into flows of the RAM air and toward the heat exchanger.
A RAM inlet header (RIH), comprising:
- a body through which RAM air flows from an inlet toward a heat exchanger;
- a plurality of nozzles arranged along a wall of the body to respectively form a curtain of cooled air along the wall and to thereby respectively direct the curtain of cooled air into flows of the RAM air and toward the heat exchanger;
- each nozzle being displaced from a neighboring nozzle and comprising:
- a first body, which is formed to define a first flowpath and which is extendable in a first direction from the wall of the body;
- a second body, which is formed to define a second flowpath and which is extendable in a second direction along a plane of the wall of the body;
- and
- a curved body interposed between the first and second bodies and by which the second flowpath is receptive of fluid from the first flowpath,
- wherein each of the nozzles is hydraulically or pneumatically inflatable or deflatable in an interior of the body.
