Popis:	This paper deals with stresses in steam-turbine blades set up during partial admission, that is, when the steam loading on the blades is intermittent. By making simplifying assumptions about the character of the loading, it is possible to develop simple relations showing how the blade stress depends on frequency, running speed, and damping. Apparatus to determine experimentally the damping of blade steels and optical equipment to investigate the exact nature of the steam forces acting on the blades in actual operation are described.
