Blade manufacturing for vertical take-off dual-engine aircraft

A rotor blade assembly for an aircraft, comprising:

• a rotor blade;
• and
• a blade cuff coupled to the rotor blade, the blade cuff comprising at least one ridge and at least one notch disposed on an interior surface of the blade cuff for coupling the blade cuff to a rotor hub;
• wherein:
• the at least one ridge extends radially inward from a blade cuff sleeve toward a center of the blade cuff and is radially positioned around the interior surface of the blade cuff sleeve;
• the at least one notch is recessed into the blade cuff sleeve, away from the center of the blade cuff, and extends from the interior surface toward the blade cuff sleeve;
• a distal end diameter of the blade cuff is larger in diameter than a middle portion diameter of the blade cuff;
• the rotor blade is wrapped by a plurality of fibers;
• at least a subset of the plurality of fibers extend longitudinally along the rotor blade toward the blade cuff, the plurality of fibers continuing past the distal end diameter of the blade cuff and wrapping around the middle portion diameter of the blade cuff;
• and
• the rotor blade comprises a plurality of weights disposed in a forward edge section of the rotor blade to balance a front side of the rotor blade and a backside of the rotor blade.
