In addition, the manufacturer is investigating the possibility of using ALM swirlers in the engines, but Szolwinski stresses that no final decision has been made.

definition swirler from a patent
a swirl stabilizer (e.g., one or more swirlers) may be provided. The role of the swirl stabilizer is to generate turbulent flows within the combustor to better atomize the fuel for the combustion process. In implementations, a swirler may be part of the combustor that passes through the dome of a jet engine. The primary air flows through it as it enters in before the combustion zone. The duty of the swirler is to create turbulence in the airflow to readily mix the fuel within the air.
