    摘要: A heat resistant panel has a bulkhead and a swirler adjacent a combustion chamber. The heat resistant panel comprises an inner panel for facing the combustion chamber and defining a first exit port at an upstream end thereof configured to direct cooling air into the combustor chamber in a first direction adjacent the bulkhead. A second exit port at a downstream end thereof is configured to direct cooling air into the combustor chamber in a second direction with an axial direction defined between the upstream and downstream ends. The first and second directions have opposed axial components. A heat resistant structure and a combustor are also disclosed.

    摘要: A cooling system having one or more pin fins with reduced mass for a gas turbine engine is disclosed. The cooling system may include one or more first surfaces defining at least a portion of the cooling system. The pin fin may extend from the surface defining the cooling system and may have a noncircular cross-section taken generally parallel to the surface and at least part of an outer surface of the cross-section forms at least a quartercircle. A downstream side of the pin fin may have a cavity to reduce mass, thereby creating a more efficient turbine airfoil.

    摘要: A turbine airfoil vane usable in a turbine engine and including at least one cooling system with an impingement plate having one or more impingement nozzles is disclosed. The turbine vane impingement nozzles may extend towards an outer wall forming the turbine vane and may reduce the mixing of cooling fluids and impingement jets found in conventional configurations. Instead, the nozzles terminate within close proximity of the outer wall, thereby reducing the effect of cooling fluid cross flow.
