Airfoil having tapered buttress

摘要

An airfoil includes an airfoil body that defines a longitudinal axis. The airfoil body includes a leading edge and a trailing edge and a first side wall and a second side wall that is spaced apart from the first sidewall. The first side wall and the second side wall join the leading edge and the trailing edge and at least partially define a cavity in the airfoil body. At least one of the first side wall and the second side wall includes at least one longitudinally elongated buttress that tapers longitudinally. The at least one longitudinally elongated buttress defines an increased thickness of, respectively, the first side wall or the second sidewall. The at least one longitudinally elongated buttress projects partially across the cavity toward the other of the first side wall or the second sidewall.

1. An airfoil comprising:
an airfoil body defining a longitudinal axis, the airfoil body including a leading edge and a trailing edge and a first side wall and a second side wall that is spaced apart from the first side wall, the first side wall and the second side wall joining the leading edge and the trailing edge and at least partially defining a cavity in the airfoil body, and at least one of the first side wall and the second side wall including at least one longitudinally elongated buttress that tapers longitudinally, the at least one longitudinally elongated buttress defining an increased thickness of, respectively, the first side wall or the second side wall, the at least one longitudinally elongated buttress projecting partially across the cavity toward the other of the first side wall or the second side wall, wherein the at least one longitudinally elongated buttress includes a first buttress on the first side wall and a second buttress on the second side wall, and further including at least one support arm projecting from the first buttress and connecting to the second buttress.
