Abstract
A main rotor assembly for a rotary wing aircraft includes a blade assembly secured to a rotor hub. The blade assembly includes a rotor blade and a slat positioned to define a slat gap between the rotor blade and the slat. One or more struts extend from the rotor blade to the slat to position the slat and control motion of the slat. The rotor blade and the slat are secured to a common rotor cuff such that the rotor cuff acts as a centrifugal force support.
