SPLAYED INLET GUIDE VANES

摘要

A system for directing the flow of a fluid and controlling the rate of flow of the fluid. The system comprises a channel for directing the flow of the fluid; at least a pair of articulating vanes positioned within the channel for controlling the flow rate of the fluid within the channel; and a linkage between the vanes coupling the articulation of each of the vanes to the other of the vanes, wherein each vane imparts a force on the linkage when the relative angle of attack is greater than zero, wherein the force imparted on the linkage by one of the vanes is at least partially cancelled by the force imparted on the linkage by the other of the vanes during the articulation of the vanes.

1. A system for directing the flow of a fluid and controlling the rate of flow of the fluid, said system comprising:
a channel for directing the flow of the fluid; at least a pair of articulating vanes positioned within said channel for controlling the flow rate of the fluid within said channel, each of said vanes comprising a pair of lateral major surfaces forming a leading edge and a trailing edge of said vane, and an axis of articulation intersecting said vane at a point spaced from the aerodynamic center of said vane; and a linkage between said vanes coupling the articulation of each of said vanes to the other of said vanes, wherein each vane imparts a force on said linkage when the relative angle of attack is greater than zero, wherein the force imparted on said linkage by one of said vanes is at least partially cancelled by the force imparted on the linkage by the other of said vanes during the articulation of said vanes.
