Abstract
An airfoil include an airfoil wall that defines a leading end, a trailing end, a first side wall, and a second side wall. A rib connects the first and second side walls of the airfoil wall. The rib includes a first arm by which the rib is solely connected to the first side wall, and second and third arms by which the rib is solely connected to the second side wall.
Claims22
An airfoil comprising:
- an airfoil wall defining a leading end, a trailing end, a first side wall, and a second side wall;
- and
- a rib connecting the first and second side walls of the airfoil wall, the rib including a first arm by which the rib is solely connected to the first side wall, and
- second and third arms by which the rib is solely connected to the second side wall, the second and third arms defining shoulders such that a portion of the rib formed by the second and third arms is U-shaped.

An airfoil comprising:
- an airfoil wall defining a leading end, a trailing end, a first side wall, and a second side wall;
- and
- first and second ribs each connecting the first and second side walls of the airfoil wall, each of the first and second ribs including
- a first arm by which the respective first or second rib is solely joined to one of the first or second side walls, and
- second and third arms by which the respective first or second rib is solely connected to the other of the first or second side wall,
- wherein the first and second ribs have one of the following configurations:
- (i) the first arm of the first rib is connected to the first side wall and the second and third arms of the first rib are connected to the second side wall, and the first arm of the second rib is connected to the second side wall and the second and third arms of the second rib are connected to the first side wall, the first and second ribs defining a Z-shaped cooling channel there between, or
- (ii) the first arm of the first rib is connected to the first side wall and the second and third arms of the first rib are connected to the second side wall, and the first arm of the second rib is connected to the first side wall and the second and third arms of the second rib are connected to the second side wall, the first and second ribs defining a T-shaped cooling channel there between.
