ABSTRACT:
A propeller blade made of an advanced composite of uniaxial fibers laminated in crossplies to take advantage of their high axial strength. The thinness and strength of the plies are exploited in assembling the plies at various orientations to produce propeller blades which respond to changing aerodynamic loads in the complex ways necessary to maintain an optimum shape.
