Device for Controlling Angular Position of Turbine Blades of a Propeller Device

摘要

A device for automatic control of an angular position of turbine blades of a propeller device, in which the turbine blades are rotatable about a rotational axis and are pivotally displaceable about their respective pivot axes. The device comprises a set of control blades kinematically connected with the turbine blades, said control blades are pivotally displaceable about respective pivot axes once the propeller device is exposed to a flow of fluid. The device further comprises a transmission unit configured for transmitting pivotal displacement of the control blades to the turbine blades such that the turbine blades could be pivoted by the control blades. Pivoting of the turbine blades takes place simultaneously with the pivoting of the control blades. The angular disposition of the turbine blades is automatically set and remains invariant irrespective of direction of the flow of fluid.

1. A device for control of an angular position of turbine blades of a propeller device, wherein the turbine blades are rotatable about a rotational axis and are pivotally displaceable about their respective pivot axes, said device comprising:
a) a set of control blades connected with the turbine blades and pivotally displaceable about respective pivot axes thereof when propeller device is exposed to a flow of fluid; and b) a transmission unit configured for transmitting pivotal displacement of the control blades to the turbine blades such that turbine blades could be pivoted in respect to their pivot axes by the control blades via said transmission unit, wherein pivoting of the turbine blades takes place simultaneously with pivoting of the control blades, wherein the arrangement of said control blades being such that an angle of attack of the turbine blades is set and maintained automatically by said control blades irrespective of direction of the fluid flow.
