ABSTRACT:
A gas turbine engine vane and method of manufacture. In one form of the present invention a vane is non destructively removeable from a vane segment to allow individual components to be replaced. The vane and endwalls are coupled together by a retainer that is formed in place between the vane and the endwall and that can be removed by conventional techniques. In one form the retainer fills a pair of corresponding grooves in the vane and endwall member so as to mechanically couple the components together and minimize fluid leakage therebetween. The retainer being nonmetallurgically coupled to the vane and endwall member. A portion of the vane being allowed to move relative to the endwall in response to thermal conditions.
