Abstract
A combustion chamber suitable for a gas turbine engine is provided with at least one Helmholtz resonator having a resonator cavity and a resonator neck in flow communication with the chamber interior. The resonator neck is provided with at least cooling holes extending through its wall for improved damping and cooling, at least one of the holes is directed towards the resonator cavity.
Claims13
A combustion chamber for a gas turbine engine comprising at least one Helmholtz resonator having a resonator cavity and a resonator neck in flow communication with the interior of the combustion chamber, the neck having cooling holes extending through a wall thereof, at least one of the cooling holes having an axis that is directed towards the resonator cavity such that in use the cooling holes direct cooling air into the resonator cavity.
A Helmholtz resonator for a gas turbine engine combustion chamber;
- the said resonator having a resonator cavity and a resonator neck for flow communication with the interior of the combustion chamber, the neck having cooling holes extending through a wall thereof, at least one of the cooling holes having an axis that is directed towards the resonator cavity such that in use the cooling holes direct cooling air into the resonator cavity.
