Résumé du livre
Light-weight design concepts were developed and tested in a full-scale turbine wheel with a tip diameter of 34.3 inches and a tip speed of 1190 feet per second. The rotor consisted of two thin A-286 alloy disks attached to each other by spacers and bolts with a separation of 0.625 inch. The disks were contoured for optimum stress distribution. The turbine blades were hollow castings of HS-21 (AMS 5385A) alloy with an integral serrated root.
