Control device for a stage of blades with variable pitch
摘要:
Device for controlling pivoting blades or variable pitch blades (3) in a turbine in which the control ring (10) rotates under the effect of an angled cam (15) controlled by a system with a connecting rod (22) and crank (21). This system imposes a non-linear rotation law between the blades (3) and the crank (21).
