Abstract
A ceramic matrix composite (CMC) airfoil assembled from a pressure side wall () and a suction side wall () joined by interlocking joints () at the leading and trailing edges () of the airfoil to produce a tapered thin trailing edge. The trailing edge () is thinner than a combined thicknesses of the airfoil walls (). One or both of the interlocking joints () may be formed to allow only a single direction of assembly, as exemplified by a dovetail joint. Each joint () includes keys (F,F,F,F) on one side and respective keyways (K,K,K,K) on the other side. Each keyway may have a ramp () that eliminates indents in the airfoil outer surface that would otherwise result from the joint.
