Abstract
A turbomachine including a combustion chamber provided with systems for injecting fuel into the chamber, and with at least one spark plug is disclosed. The injection system located as close as possible to the spark plug is configured in order to produce a pool of fuel having an angle of opening of a greater value than that of the pools produced by the other injection systems, and having a flow of fuel greater than that of the other injection systems.
Claims10
A turbomachine, comprising:
- an annular combustion chamber delimited by internal and external coaxial revolution walls;
- a chamber base wall connecting upstream ends of the internal and external revolution walls and comprising openings for mounting fuel injection systems in the chamber;
- and
- at least one spark plug mounted in an orifice of the external revolution wall of the chamber, and oriented towards an axis of one of the injection systems,
- wherein the injection system located closest to the at least one spark plug produces a substantially tapered pool of sprayed fuel having an angle of opening of a greater value than an angle of openings of the pools produced by other injection systems, and
- wherein a flow of fuel of the closest injection system is greater than a flow of fuel of the other injection systems.
