Abstract

Abstract An annular combustion chamber comprising a plurality of ducts adapted to inject axially in an upstream direction a gasiform mixture containing vaporized fuel, each duct being associated with a pair of radial nozzles adapted to inject into said chamber two air jets directed toward one another, the geometrically defined area in which the jets are to meet being located at the outlet end of said duct.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 259 words
An annular combustion chamber fed with liquid fuel and compressed air comprising: two coaxial annular casings enclosing between them an annular space; two coaxial annular walls coaxial with said casings, housed within said annular space and the interval between which defines an annular combustion space through which the combustion gases are adapted to flow, said walls defining between them and the corresponding casings annulAr passages; means adapted to supply said annular passages with compressed air; a dome closing the combustion space at one end thereof; a plurality of means adapted to inject into the region of the combustion space lying in the vicinity of the dome vaporized fuel, each of said means having an outlet opening facing the dome and through which last-mentioned vaporized fuel is exhausted towards the dome in a direction substantially parallel to the axis of the annular walls, said outlet openings being distributed along an annular line extending at substantially equal distances from the said annular walls; and a plurality of nozzlelike ports extending across said annular walls and connecting each of the annular passages with the annular combustion space, a nozzlelike port across one annular wall registering substantially radially with a corresponding nozzlelike port across the other annular wall and with a corresponding outlet opening through which vaporized fuel is exhausted said dome having openings adjacent said plurality of means for injecting vaporized fuel, deflector means surrounding each of said means for injecting vaporized fuel adjacent said dome and adapted to deflect air passing through said openings in said dome toward said annular walls.
