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.

A fuel distribution manifold comprises an outer shell having an inner surface. The outer shell defines an inlet for receiving fuel from a parent supply line, a base opposite the inlet, a central manifold axis that intersects the inlet, and a plurality of outlets for delivering fuel to offspring fuel lines, each outlet defining a respective outlet axis. In one exemplary embodiment, a fuel distribution manifold also comprises a center-body having an outer surface and being positioned within the outer shell wherein the outer surface of the center-body and the inner surface of the outer shell define a flow-path through which fluid flows from the inlet to the plurality of outlets. In another exemplary embodiment, at least one of the outlets is positioned adjacent to the base and oriented so that its respective outlet axis is rotated relatively to a radial direction that intersects the central manifold axis.

A fuel distribution manifold comprising: an outer shell having an inner surface and being configured for containing a flow of pressurized fuel, the outer shell defining: an inlet for receiving a supply of fuel from a parent supply line, the inlet being formed to define a locally narrow-most portion;a base opposite the inlet;a plurality of outlets for delivering fuel to offspring fuel lines, each outlet defining a respective outlet axis; anda central manifold axis that intersects the inlet;the fuel distribution manifold further comprising:a center-body having a frusto-conical outer surface leading to a convex end and being positioned within the outer shell; andan inlet screen retained in and extending across a plane of the inlet,the center body extending axially such that a distal-most portion of the convex end of the center body is aligned with the locally narrow-most portion of the inlet to support the inlet screen, and an outer surface of the center-body and the inner surface of the outer shell defining a flow-path through which fluid flows from the inlet to the plurality of outlets. 2. A fuel distribution manifold as in claim 1, wherein at least one of the plurality of outlets is positioned adjacent to the base and oriented so that its respective outlet axis is rotated relatively to a radial direction that intersects the central manifold axis. 3. A fuel distribution manifold as in claim 1, wherein the center-body is positioned within the outer shell so as to divide the fluid entering the fuel distribution manifold through the inlet. 4. A fuel distribution manifold as in claim 1, wherein the center-body is aligned with the central manifold axis. 5. A fuel distribution manifold as in claim 1, wherein the center-body is fixed to the base and extends axially from the base. 6. A fuel distribution manifold as in claim 1, wherein the outer surface of the center-body is symmetric about the central manifold axis. 7. A fuel distribution manifold as in claim 1, wherein the outer surface of the center-body and the inner surface of the outer shell define a flow-path that decreases in cross-sectional area with increasing distance along the flow-path. 8. A fuel distribution manifold as in claim 1, wherein the outer surface of the center-body is configured to cause fluid to accelerate as it flows through the fuel distribution manifold. 9. A fuel distribution manifold as in claim 1, wherein the flow-path is characterized by a cross-sectional area that decreases with distance along the central manifold axis. 10. A fuel distribution manifold as in claim 1, wherein the flow-path is characterized by a cross-sectional area that decreases at least linearly with distance along the central manifold axis. 11. A fuel distribution manifold as in claim 1, wherein an area of the flow-path at the inlet is at least about four times as great as an area of the flow-path at the plurality of outlets. 12. A fuel distribution manifold as in claim 1, wherein an area of the flow-path at the inlet is less than about eight times as great as an area of the flow-path at the plurality of outlets. 13. A fuel distribution manifold as in claim 1, wherein at least one of the plurality of outlets is positioned adjacent to the base and oriented so that its respective outlet axis is rotated relatively to a radial direction that intersects the central manifold axis. 14. A fuel distribution manifold as in claim 1, wherein the outer surface of the center-body is coated with a material that repels fuel. 15. A fuel distribution manifold as in claim 1, wherein the inner surface of the outer shell is coated with a material that repels fuel. 16. A fuel distribution manifold comprising: an outer shell having an inner surface that defines a flow-path through which fluid flows from an inlet to a plurality of outlets;the outer shell also defining: an inlet for receiving a supply of fuel from a parent supply line, the inlet being formed to define a locally narrow-most portion;a base opposite the inlet;a plurality of outlets for delivering fuel to offspring fuel lines, each outlet defining a respective outlet axis; anda central manifold axis that intersects the inlet;the outer shell being configured for containing a flow of pressurized fuel;an inlet screen retained in and extending across a plane of the inlet; anda center-body having a frusto-conical outer surface, which is entirely smooth, leading to a convex end and being positioned within the outer shell, the center body extending axially such that a distal-most portion of the convex end of the center body is aligned with the locally narrow-most portion of the inlet to support the inlet screen, andat least one of the plurality of outlets being positioned adjacent to the base and oriented so that its respective outlet axis is rotated relatively to a radial direction that intersects the central manifold axis. 17.
