Embodiment Construction

[0029] Figure 1 is a partial schematic view of a turbine, shown along the X-X longitudinal axis. Along the longitudinal axis, the turbine specifically comprises: an annular compression section 100; an annular combustion section 200 arranged at the outlet of the compression section 100 in the direction of air flow through the turbine; and an annular turbine section 300 located at the outlet of the combustion section 200. The air injected into the turbine can thus pass continuously through the compression section 100 , then the combustion section 200 , and finally enter the turbine section 3 .

[0030] The compression section 100 consists of a plurality of rotors 102, each equipped with a blade 104 (Figure 1 shows only the last stage of the compression section). The blades 104 of these stages are arranged in an annular channel 106 through which the turbine air passes, the channel section decreasing gradually from upstream to downstream. In this way, when the air injected into t...

Abstract

The invention relates to a turbomachine combustion chamber comprising an inner annular wall, an outer annular wall surrounding the inner wall so as to co-operate therewith to define an annular space forming a combustion area, a plurality of fuel injector systems comprising pilot injectors alternating circumferentially with full-throttle injectors, and at least one air admission opening out into the upstream end of the combustion area in a substantially longitudinal direction. The outer wall has a plurality of pilot cavities extending between the two longitudinal ends of the outer wall and extending radially towards thereof, the pilot cavities being fed with air from outside the combustion chamber in a common substantially circumferential direction. Each pilot injector opens out radially into a pilot cavity, and each full-throttle injector opens out radially between two adjacent pilot cavities.

Description

technical field [0001] The invention relates to the general field of combustion chambers of aeronautical or land turbine engines. Background technique [0002] Generally speaking, an aviation or land turbine engine includes a device, which is specifically composed of the following parts: an annular compression section for compressing the air flowing through the turbine; an annular combustion section located at the outlet end of the compression section. Here, air from the compression section is mixed with fuel and combusted; and an annular turbine section at the exit end of the combustion section with a rotor that is rotated by the gas from the combustion section. [0003] The combustion section takes the form of a number of rotor stages, each rotor stage is equipped with blades located in an annular channel through which the turbine air flows, the cross-section of which decreases from upstream to downstream. The combustion section consists of a combustion chamber, also in t...
