A combustor panel is disclosed herein. The combustor panel includes a top side, a bottom side opposite the top side, a feature coupled to the top side and extending orthogonally away from the top side, the feature defining a first space on the bottom side beneath the feature, a first plurality of cooling holes extending in a first direction from the top side to the bottom side, a second plurality of cooling holes extending in a second direction from the top side to the bottom side, the second direction being rotated about 1° to about 60° counter-clockwise from the first direction, and a third plurality of cooling holes extending in a third direction from the top side to the bottom side, the third direction being about rotated 1° to about 60° clockwise from the first direction.

Stud film cooling for double wall combustors

A diffuser case for a gas turbine engine including: a pre-diffuser; a diffuser case defining a dump region, an inner plenum, and an outer plenum, the pre-diffuser being fluidly connected to the inner plenum and the outer plenum through the dump region; a tangential onboard injector module fluidly connected to the inner plenum through inlet orifice located in the diffuser case proximate an aft end of the inner plenum; and an inlet extender initiating at the inlet orifice of the tangential onboard injector module, extends through the inner plenum, and terminates at a distal end proximate the pre-diffuser.

Tangential onboard injector inlet extender

An assembly is provided for a gas turbine engine. This assembly includes a combustor wall, a case and an inlet. The combustor wall is configured with a quench aperture. The case is displaced from the combustor wall such that a plenum is formed by and extends between the combustor wall and the case. The case includes a case wall, a deflector and a conduit. The deflector projects out from the case wall into the plenum towards the combustor wall. The deflector is arranged upstream of the quench aperture. The inlet to the conduit is arranged next to and downstream of the deflector.
