| 摘要 |
A combustor for generating a hot gas stream by the combustion of fuel in a pressurized airstream is disclosed including a generally toroidal-shaped combustion chamber of relatively short axial length, an annular orifice providing for the entry of a main airstream into the combustion chamber and a premixing chamber for generating and directing a vapor phase air-fuel premixture into the entering main airstream to form a combustible mixture for burning in the combustion chamber. In a preferred form, the mixture burns along a generally toroidal-helical gas flow path. The combustor is particularly suited for use in a gas turbine engine.
