Abstract

293,009. Aktiebolaget Ljungstr÷ms Angturbin. June 30, 1927, [Convention date]. Blades for gas or steam turbines have a greater thickness at the inlet side than the outlet side to prevent eddy currents due to variations in the relative inlet velocity. 'The inlet edges may be of circular, elliptical, parabolic, or hyperbolic shape. The pitch of the blades is 0.8 to 1.2 times the width of the blades measured in the direction of flow. The pitch is related to the height of the the blades as k: #sin a where k is equal to or greater than 0.5 and a is the outlet angle of the blade.
