Fuel supply rail for combustion/post-combustion chamber of e.g. jet engine of aircraft, has duct whose section decreases from inlet until part of duct diametrically opposed to inlet so as to standardize rate flow on circumference of duct

摘要

The rail has an annular duct (38) comprising a fuel inlet (34) at a lower part when the rail is assembled in a turboshaft engine. Fuel outlet openings (36) are distributed on circumference of the duct. A section of the duct decreases from the inlet until a part of the duct diametrically opposed to the inlet so as to standardize a fuel rate flow on the circumference of the duct, where the duct is made of curved sectors that are arranged end to end. The duct is provided symmetrical with respect to an axial plan containing diameter of the duct and passing through the inlet. An independent claim is also included for a turboshaft engine including an input hopper.
