Abstract

A combustor assembly includes a first wall, a second wall, a bulkhead and a plurality of fuel injectors. The bulkhead forms a combustion chamber with the first and the second walls. The fuel injectors are configured with the first wall in a unique and/or a fluctuating pattern.

Claims (11)

1. An assembly for a turbine engine, the assembly comprising:

an annular combustor with a combustion chamber extending circumferentially around and axially along a centerline;

the annular combustor including a plurality of first fuel injectors and a plurality of second fuel injectors disposed about the centerline;

wherein the first fuel injectors are adapted to inject fuel axially into the combustion chamber;

wherein the second fuel injectors are adapted to unevenly inject fuel radially into the combustion chamber, a first adjacent pair of the second fuel injectors are circumferentially separated by a first distance, and a second adjacent pair of the second fuel injectors are circumferentially separated by a second distance that is different than the first distance; and

wherein each of the second fuel injectors is circumferentially aligned with a respective one of the first fuel injectors.

2. The assembly of claim 1 , wherein

one of the second fuel injectors is adapted to inject fuel into the combustion chamber at a first rate; and

another one of the second fuel injectors is adapted to inject fuel into the combustion chamber at a second rate that is different than the first rate.

3. The assembly of claim 1 , wherein the first adjacent pair of the second fuel injectors are axially separated by a third distance.

4. The assembly of claim 1 , wherein one of the first fuel injectors is circumferentially aligned with a gap between the second adjacent pair of the second fuel injectors.
