Claim 0:
1. A gas turbine engine comprising:
an airfoil defining a spanwise direction, a root end, and a tip end, the airfoil comprising
a body defining a pressure side and a suction side and extending along the spanwise direction between the root end and the tip end, the body formed of a composite material; and
a spar enclosed in the body of the airfoil extending along the spanwise direction, the spar comprising a plurality of spar segments arranged in an overlapping configuration along the spanwise direction;
wherein the plurality of spar segments includes a first spar segment and a second spar segment, wherein the first spar segment overlaps with the second spar segment at a first overlap section of the first spar segment, wherein the first spar segment defines a first overall length and a first overlap length of the first overlap section, wherein the first overlap length is equal to 15% or less of the first overall length.
