    摘要: The present invention relates to a burner for a combustion chamber of a gas turbine with a mixing and injection device (43), wherein the mixing and injection device (43) is comprising a limiting wall (44) that defines a gas-flow channel (440) and at least two streamlined bodies (22), each extending in a first transverse direction (49) into the gas-flow channel (440). Each streamlined body (22) has two lateral surfaces that are arranged essentially parallel to the main-flow direction (14), the lateral surfaces being joined to one another at their upstream side to form a leading edge of the body and joined at their downstream side to form a trailing edge of the body (22). Each streamlined body (22) has a cross-section perpendicular to the first transverse direction (49) that is shaped as a streamlined profile. At least one of said streamlined bodies (22) is provided with a mixing structure and with at least one fuel nozzle (15) located at its trailing edge for introducing at least one fuel essentially parallel to the main-flow direction (14) into the flow channel (440), wherein at least two of the streamlined bodies (22) have different lengths along the first transverse direction (49) such that they may be used for a can combustor.

    摘要: A jet engine is provided with an inlet 11 and a combustor 12 having a fuel injection port 30a. The combustor 12 has a wall part 16 that defines an air flow path FA. The wall part 16 has a ramp part 60, which has an inclined face 62, and a first wall face 17 extending to the front-side end of the inclined face 62. The fuel injection port 30a is positioned at the ramp part 60. The inclination angle θ relative to the first wall face 17 of the inclined face 62 is at least 13.5 degrees. The height by which the ramp part 60 protrudes from the first wall face 17 does not exceed one fifth of the height of the inlet of the combustor 12. Thus provided are a jet engine and a flying object in which the inclination angle of the inclined face of a ramp is made larger so as to promote the mixing of fuel and air and to allow for stable flame holding at the rear of the ramp.

    摘要: The present embodiment sufficiently ensures the ignition stability and the flame-holding property of an afterburner 25 while suppressing a reduction in the engine efficiency of an aircraft engine 1. A flame holder 45 is disposed directly downstream of an injection hole 41 of a fuel injector 39 in a liner 31. The flame holder 45 comprises: a ring-shaped annulus flame-holding member 49 which is provided on the inner circumferential surface of the liner 31 and is capable of propagating a flame in the circumferential direction; and a plurality of radial flame-holding members 51 which are radially disposed inwards of the annulus flame-holding member 49 and are capable of propagating the flame in the radial direction. A guide ring 53 is provided inwards of the radial flame-holding members 51, and a ring-shaped guide channel 57 that guides a fuel-containing mixed gas in the downstream direction is formed between the outer peripheral surface of the guide ring 53 and the inner peripheral surface of the annulus flame-holding member 49.
