Abstract
527,195. Elastic-fluid turbines. BRITISH THOMSON-HOUSTON CO., Ltd. April 3, 1939, No. 10388. Convention date, April 1, 1938. [Class 110 (iii)] To avoid the appearance of resonance phenomena between vibrations in the fluid space of high-pressure, elastic-fluid turbines, and the natural frequency of vibration of a turbine rotor, the rotor is designed so that for fluid velocities between 40 and 410 meters per second, the rotor frequency is outside the range of the frequencies N in the equations given below. The equations giving curves A and B are N = 1.5 = 10<6> / C<1.3> and N = 14.3 (C/100)4.8 respectively, "C" being the fluid velocity in meters per second, and N fluid vibrations per minute. The dotted line N<1> represents the limiting value of N given by the above equations.
