The invention relates to a turbine engine combustion assembly (20), which includes: an annular flame tube (21) including a front wall (23), a rear wall (24) and a bottom (22) arranged facing an engine shaft (30); an injection wheel (41) rotated by said engine shaft (30), partially projecting into the bottom (22) of the flame tube (21) and configured such as to spray fuel into the flame tube by centrifugation; and at least one injector (35), capable of depositing a film of fuel on said injection wheel (41), said combustion assembly being characterised in that said injector (35) is arranged so as to pass through said upstream area of the front wall (23) or the rear wall (24) of the flame tube (21), so that the injection opening thereof (37) opens into said tube (21), opposite the portion (43) of said injection wheel (41) which is located inside said flame tube (21).

An airblast injector for gas turbines is disclosed. The airblast injector assembly consists of fuel swirler, a swirler cup, and a combustor dome. The airblast injector is designed to improve engine performance without using a fuel staging system to incorporate pressure injectors. The swirler cup is provided with pressurized air which exits the swirler cup with high velocity that penetrates perpendicularly into the fuel spray cone obtained by orifices in the fuel swirler.

Provided is a rotary sprinkler that includes a housing, a rotatable irrigation head associated with a first magnet assembly, and a second magnet assembly associated with the housing and fitted with a rotary dampening mechanism. The first magnet assembly and the second magnet assembly are arranged with like poles facing each other so as to generate a repulsion force therebetween.

An electric motor assisted airblast injector design for gas turbines is disclosed. The electric motor assisted airblast injector assembly consists of an airblast injector, a high speed electric motor and a compressor. The electric motor assisted airblast injector is designed to improve engine light-off and starting reliability without using a fuel staging system to incorporate pressure injectors. A high speed motor is activated during starting to drive a compressor for locally producing pressurized air without sacrificing combustor performance. The pressurized air exiting the air swirler with high velocity penetrates perpendicularly into the fuel spray cone obtained by orifices in the fuel swirler. The amount of pressurized air through the compressor is controlled by motor speed to match fuel starting schedule and produce fuel/air mixture within flammability limits. After engine starting, the high speed motor may cut off as sufficient air pressure differential is available across the combustor.

A centrifugal conical-spray atomization device. A head portion of a needle valve is provided with a throttling guidance cone. A seat surface of the needle valve mates with seat surface of a spin chamber to open and close a spray hole in a pulsatory manner. A plurality of tangential holes are provided between a pressure chamber and a spin chamber. After being spun tangentially by the spin chamber, fuel is sprayed from a spray opening with a tangential force, forming a hollow umbrella-like fuel film without a compact fuel spray core. The umbrella-like fuel film has a controllable penetration distance and spins at a high speed in a combustion chamber. The centrifugal conical-spray atomization device not only exhibits a wide adjustable range of fuel flow, but is able to automatically open and close the spray hole, while carbon deposition would not easily form to block the spray hole.
