연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

The elbow or T-shaped structure, includes an external wall (14)and continuous internal walls (22) made in one piece. This therefore materializes, between the inlet (10) and each outlet (12) of the structure, at least one continuous passage to direct a fluid circulating inside it. The structure according to the invention is manufactured by diffusion welding and superplastic forming, from titanium alloy sheets. One application is for aircraft de-icing circuits.

1. Thin walled compartmented tubular structure enabling a fluid to flow between an inlet tubular part and at least one outlet tubular part oriented in different directions, the said structure consisting of: an external wall and continuous internal walls produced in one piece with the external wall, such as to materialise between the inlet tubular part and each outlet tubular part at least one independent continuous passage to guide the fluid, wherein the internals walls are formed in an X-shaped cross-section in the inlet tubular part and an X-shaped or Y-shaped cross section in each outlet tubular part.2. Thin walled compartmented tubular structure in accordance with claim 1, in which each continuous internal wall includes two planar end portions, located in the inlet tubular part and outlet tubular part, and an internal curved portion, in the shape of the fulcrum of a cone, connecting together the two planar end portions without any discontinuity.3. Thin walled compartmented tubular structure in accordance with claim 2, including two outlet tubular parts aligned and oriented approximately at right angles to the inlet tubular part, in which the independent continuous passage connecting the inlet tubular part to each outlet tubular part is materialised between the external wall and two continuous internal walls.4. Thin walled compartmented tubular structure in accordance with claim 1, in which each of the independent continuous passages exhibits an approximately constant passage cross-section between the inlet tubular part and each outlet tubular part.5. Thin walled compartmented tubular structure enabling a fluid to flow between an inlet tubular part and at least one outlet tubular part oriented in different directions, the said structure including an external wall and additionally including continuous internal walls produced in one piece with the external wall, such as to materialise between the inlet tubular part and each outlet tubular part at least one independent continuous passage to guide the fluid, in which each continuous internal wall includes two planar end portions, located in the inlet tubular part and outlet tubular part, and an internal curved portion, in the shape of the fulcrum of a cone, connecting together the two planar end portions without any discontinuity, and wherein the thin walled compartmented tubular structure is formed of sheets of thickness equal to about 2 mm at the most, in which the internal curved portion of each continuous internal wall intercepts a median plane of the tubular structure along a first circular arc of radius R and the external wall along a second circular arc of radius r, such that the radius R of the first circular arc is approximately equal to three times radius r of the second circular arc.6. Thin walled compartmented tubular structure in accordance with claim 5, in which radius r of the second circular arc is approximately equal to 15 times the thickness of the said sheets.7. Thin walled compartmented tubular structure enabling a fluid to flow between an inlet tubular part and at least one outlet tubular part oriented in different directions, the said structure including an external wall and additionally including continuous internal walls produced in one piece with the external wall, such as to materialise between the inlet tubular part and each outlet tubular part at least one independent continuous passage to guide the fluid, in which each continuous internal wall includes two planar end portions, located in the inlet tubular part and outlet tubular part, and an internal curved portion, in the shape of the fulcrum of a cone, connecting together the two planar end portions without any discontinuity, including two outlet tubular parts aligned and oriented approximately at right angles to the inlet tubular part, in which the independent continuous passage connecting the inlet tubular part to each outlet tubular part is materialised between the external wall and two continuous internal walls, in which an additional internal wall is located inside the structure, in a median plane of the latter, between the external wall of the structure and the joint zones of the said continuous internal walls.8.
