ASSEMBLY DEVICE FOR DOUBLE-SKINNED AIRCRAFT FUEL PIPES

摘要

An assembly device between two sections of a double-skinned fuel pipe of an aircraft has a clamp for assembling the internal pipes, a coupling device for assembling the external pipes, a fitting extending between the ends of the external pipes of the first and second sections, with a shape complementary to the shape of an internal portion of the coupling device, and such that its section through any cutting plane perpendicular to the longitudinal axis common to the coupling device and the external pipes contains the smallest surface delimited by: a line corresponding to the intersection of the internal surface of the coupling device with this cutting plane and a straight line cutting said line at two points, this straight line being tangential to the orthogonal projection in this cutting plane, of the internal surface of the external pipes of the first or of the second section.

1. An assembly device between a first section and a second section of a double-skinned fuel pipe of an aircraft, said device comprising:
a clamp allowing one end of an internal pipe of the first section to be assembled with one end of an internal pipe of the second section; a coupling device allowing one end of an external pipe of the first section to be assembled with one end of the external pipe of the second section; and a fitting extending between the end of the external pipe of the first section and the end of the external pipe of the second section and having a shape complementary to the shape of an internal portion of the coupling device, wherein, when the first section and the second section of the fuel pipe are assembled by the assembly device, the section of the fitting through any cutting plane perpendicular to the longitudinal axis common to the coupling device, the external pipe of the first section and the external pipe of the second section contains the smallest surface delimited by: on the one hand, a line corresponding to the intersection of the internal surface of the coupling device with the cutting plane and, on the other hand, a straight line cutting said line at two points, the straight line being tangential to the orthogonal projection in the cutting plane, of the internal surface of the external pipe of the first section or of the external pipe of the second section.
