Abstract: A tube joint includes a first member and a second member. The first member has a bore defining an inner diameter. The second member has a first outer surface defining a first outer diameter with two or more helical protrusions extending radially from the first outer diameter. The two or more helical protrusions collectively define a second outer diameter. The second outer diameter of the second member is larger than the inner diameter of the first member by an amount sufficient to center and retain the second member within the bore of the first member. Brazed tube joint assemblies and methods of making brazed tube joints are also described.

Abstract: A method of manufacturing includes depositing a predetermined amount of braze material directly to a joint location of a first component and joining the first component to a second component at the braze joint location. The method also optionally includes depositing a predetermined amount of braze material directly to a joint location of the second component. Machining down the braze material on each of the first and second components can be used to provide a preformed braze joint.

Abstract: A head assembly for an ignition system includes a head block and a plurality of igniters seated in the head block. The head block has an issue aperture and defines an issue axis, and is configured and adapted for sealably coupling with an igniter combustion chamber. The igniters are arranged about the issue aperture and include respective ignition members arranged obliquely with respect to the issue axis for igniting fuel exiting the issue aperture irrespective to orientation of the ignition system.

Abstract: A method of manufacturing includes depositing a braze filler adjacent to a void between a first component and a second component thus holding the components in position before brazing. The first and second components are heated to melt and flow the braze filler into the void. A braze joint is formed between the first and second components by cooling the braze filler. Depositing the braze filler can include laser cladding the braze filler to the first and/or second components adjacent the void. The method also optionally includes welding the first and second components in position with the braze filler adjacent to the void. The braze filler may be deposited as a powder, cold spray, melted brazed filament, spherical ball or any other suitable form.
Abstract translation: 一种制造方法包括在第一部件和第二部件之间沉积与空隙相邻的钎焊填料，从而在钎焊之前将部件保持在适当位置。 将第一和第二组分加热熔化并将钎焊填料流入空隙。 通过冷却钎焊填料，在第一和第二部件之间形成钎焊接头。 堆积钎焊填料可以包括将钎焊填料激光熔合到与空隙相邻的第一和/或第二组分。 该方法还可选地包括将第一和第二部件焊接在与空隙相邻的钎焊填料的适当位置。 钎焊填料可以作为粉末，冷喷雾，熔融的钎焊长丝，球形球或任何其它合适的形式沉积。

Abstract: A nozzle tip includes a nozzle tip body defining an upstream surface and an opposed downstream surface. An outlet orifice is defined through the nozzle tip body for fluid communication from a space upstream of the upstream surface to a space downstream of the downstream surface. The outlet orifice includes a cylindrical outlet portion defining an outlet axis, and a tapered inlet portion upstream of the outlet portion. The tapered inlet portion converges down towards the outlet axis in a direction from the upstream surface toward the downstream surface.

Abstract: A fuel injector for an exhaust heater includes a cover and an air blast nozzle. The cover has a nozzle seat, a fuel inlet, and an air inlet, the nozzle seat arranged along a flow axis. The air blast nozzle is seated in the nozzle seat and has a unibody. The air blast nozzle unibody is in fluid communication with the fuel inlet and the air inlet arranged along the flow axis to port fuel and air into a combustion volume, e.g., to heat a stream of exhaust gas flowing between an engine and a catalytic reactor by combustion with fuel introduced through the fuel inlet and air introduced through the air inlet.
