Variable Camber Tandem Blade Row for Turbomachines.
Abstract
This patent application relates generally to variable pitch, flat-plate blade rows for turbomachinery, and more particularly, to variable pitch, offset multiple flat-plate blade rows for bidirectional thrust or flow devices which effectively provide variable camber blade row configurations. Multiple flat-plate blade rows of pitch adjustable blades are offset mounted in a manner such that when flat-plate blades in adjacent rows are aligned at a specific pitch setting, respective flat-plate blades of the adjacent rows nearly mate. The offset between the flat-plate blade rows functions to produce unequal pitch angle settings of the blades of adjacent rows which, in turn, function to produce the result that the respective flat-plate blades which nearly mate, in combination, produce a blade configuration which has an effective camber.
