Abstract

The invention discloses a fuel manifold for an engine combustor, a fuel manifold manufacturing method and an aeroengine. The fuel manifold for the engine combustor comprises a mounting base plate, an oil way ring and an oil way adaption port, wherein the mounting base plate is connectedly mounted on a combustion box, the oil way ring is used for providing oil ways, and the oil way adaption port is used for oil inlet and oil return. The oil way ring and the oil way adaption port are arranged on the upper surface of the mounting base plate, and the oil way adaption port is connected onto the oil way ring; the oil way ring is internally provided with an oil return way and an oil supply way, the oil way adaption port is provided with an oil inlet hole used for leading fuel in and an oil return hole used for leading fuel out, the oil inlet hole is communicated with the oil supply way, and the oil return hole is communicated with the oil return way; the mounting base plate is provided with a nozzle mounting blind hole used for mounting of a fuel nozzle, the nozzle mounting blind hole is formed from the lower surface of the mounting base plate to the interior of the oil way ring and communicated with the oil supply way and / or the oil return way. The fuel manifold not only has an oil supply function of a manifold but also has a function of serving as a border for the combustor, thereby different power requirements of engines can be met.

Description

technical field [0001] The invention relates to the field of aero-engines, in particular to a fuel manifold for engine combustion chambers. Furthermore, the present invention also relates to an aeroengine comprising the above-mentioned fuel manifold for the combustion chamber of the engine. In addition, the present invention also relates to a method of manufacturing the fuel manifold for the engine combustion chamber. Background technique [0002] The fuel manifold is an important component of the fuel system, and the reliability of the fuel manifold directly affects the stability of the aero-engine. Aeroengine fuel manifolds generally adopt an assembled structure, usually divided into two types: hard pipes and hoses. The hard tube is generally made of stainless steel, which has good strength but poor assembly. The hose is generally made of polytetrafluoroethylene material, and the outermost layer has a fireproof sleeve, which is good in assembly, but the disadvantage is ...
