Abstract
In one embodiment, a rotor blade includes a tip, a root, and a body extending between the tip and the root. The body has surfaces defining a pressure side, a suction side, a leading edge, and a trailing edge. The body further defines an inboard portion, an outboard portion, and a bend therebetween. The bend is defined such that the outboard portion extends outwardly with respect to the inboard portion. The bend is stiffened to reduce opening of the bend during deflection of the rotor blade.
