Abstract
A lug assembly can include a frame, lug base, lug, and door. The lug assembly can be attached to a projectile that can be coupled and decoupled to an aircraft via the lug assembly. The frame can slidably receive the door. The lug can connect to the lug base and rotate thereabout from a first lug position to a second lug position upon the projectile decoupling. In the second lug position, the lug is contained within the frame such that an aerodynamic profile of the projectile is preserved. The door can connect to the lug base via a closing mechanism including one or more tension mechanism that apply a closing force to the door. Upon the projectile decoupling, the closing force causes the door to slide from a first to a second position, the door transitioning the lug to the second lug position and substantially sealing the frame opening.
