摘要： A fuel spray nozzle is provided for atomising liquid in a gas, the nozzle comprising: a gas passage; a liquid passage; a prefilming surface positioned downstream of the liquid passage and the gas passage, and configured to receive liquid from the liquid passage and to receive gas from the gas passage; wherein the liquid passage terminates at an exit orifice upstream of the prefilming surface; and wherein the gas passage contains a flow perturbator upstream of the liquid passage exit orifice, to increase the turbulence of gas passing from the gas passage to the prefilming surface.

摘要： A combustion chamber comprising an upstream end wall, at least one annular wall, at least one fuel injector and at least one seal. The at least one annular wall being secured to the upstream end wall. The upstream end wall having at least one aperture. Each fuel injector being arranged in a corresponding one of the apertures in the upstream end wall and each seal being arranged in a corresponding one of the apertures in the upstream end wall and around the corresponding one of the fuel injectors. Each seal having an inner surface facing the corresponding one of the fuel injectors and an outer surface facing away from the corresponding one of the fuel injectors. Each seal abutting the corresponding one of the fuel injectors. The downstream end of each seal increasing in diameter in a downstream direction and the upstream end of each seal having a radially extending flange. Each seal having a plurality of coolant apertures extending axially through the radially extending flange and/or each seal having a plurality of thermal conductors extending axially from the radially extending flange to the downstream end of the seal.
