ABSTRACT:
There is disclosed a blade and mounting means particularly useful in the construction of axial flow compressors where blades of airfoil configuration are mounted in blade carriers so as to be removable and replaceable by manipulation of nuts on adapters arranged radially, which adapters include tubular bodies having frusto-conical heads mounted in mating sockets in the carrier or carriers, the blades have portions positioned in the adapters and tightening of the nuts causes the adapters to grip the blades and fix them in adjusted positions, a seal to reduce losses being formed on the blades for use in those cases where such losses may be critical.
