Variable camber vane and method therefor
First Claim
1. A variable camber vane having a first portion adapted to be secured to a mounting means, a second free tip portion spaced from said first secured portion, and a working face disposed within and diverting flow of a working fluid, for temperature-responsive deflection of said tip portion as respects said root coorelative to the temperature of said working fluid,said vane comprising:
- a. a sintered, generally laminar composite of a first amorphous metallic composition as a first vane element;
b. a second amorphous metallic composition as a second vane element;
c. said vane elements being characterized in that the coefficients of thermal expansion for each of said first and second compositions differ in a manner that the camber of said vane varies in response to thermal variations of said working fluid;
d. each of said amorphous metallic compositions being an RSR amorphous metallic composition;
e. each of said first and second vane elements being formed with an array of lateral surface grooves disposed generally along a flow path of said working fluid.

Abstract
A variable camber vane particularly suitable for use as a variable stator vane (20) has a secured root (22), a free tip (24) and a working face (26) disposed within and diverting flow of a working fluid, exhibiting temperature-responsive deflection of the tip as respects the root correllative to the temperature of the working fluid, is comprised of a sintered, generally laminar composite of a first amorphous metallic composition as a first vane element (32) and a second amorphous metallic composition as a second vane element (34), wherein the coefficients of thermal expansion for each of the compositions differ; whereby the camber of the vane varies in response to thermal variations of the working fluid.

3. A vane assembly particularly adapted for use in an air breathing turbine engine, said vane assembly comprising:
-
a. a first outer ring mounting member; b. a second inner ring mounting member disposed within said first member; c. a plurality of vane members mounted in an area between said first and second ring mounting members, each vane member being a variable camber vane, having a first secured portion by which it is mounted to said first and second ring mounting members, a second freetip portion spaced from said first secured portion, and a working face disposed within and diverting flow of a working fluid, for temperature responsive deflection of said tip portion as respects said root correlative to the temperature of said working fluid, each of said vane members comprising; i. a sintered, generally laminar composite of a first amorphous metallic composition as a first vane element; ii. a second amorphous metallic composition as a second vane element; iii. said vane elements being characterized in that the coefficients of thermal expansion for each of said first and second compositions differ in a manner that the camber of said vane varies in response to thermal variations of said working fluid; iv. each of said amorphous metallic compositions being an RSR amorphous metallic composition; v. each of said first and second vane elements being formed with an array of lateral surface grooves disposed generally along the flow path of said working fluid. - View Dependent Claims (4)
