First Claim
Patent Images
1. A combustor for an engine assembly, comprising:
- a cylindrical wall forming a combustion chamber in which an air and fuel mixture is combusted; and
a plurality of effusion cooling holes formed in the cylindrical wall, the plurality of effusion cooling holes oriented such that cooling air flowing therethrough cools the cylindrical wall with effusion cooling, convection cooling, and impingement cooling.
