[Class 110 (iii)] Turbine blades, or like projections, secured in or upon a rotor by inter-engaging spiral threads, as described in U.S.A. Specification 2,240,742, are so assembled that they abut against one another with a circumferential pressure of the order of five to twenty tons per square inch.
