ABSTRACT:
A hollow turbomachinery blade is formed by way of casting or the like with an open tip end except for a bridge which is formed integrally with the blade side walls at a central position with respect to the leading and trailing edges. Also formed integrally with the blade side walls, proximate the tip end openings near the leading and trailing edges, are a plurality of supporting and retaining bosses, the supporting bosses being in substantially the same plane as the cast cap, and the retaining bosses being disposed radially outward thereof. Each of the forward and rear tip caps is installed by placing it over the bridge ad then sliding it either forward or rearward to be captured by the supporting and retaining bosses and to thereby close the respective tip opening. Each of the tip caps is then brazed into position so as not to allow its sliding back out.
