Abstract: Embodiments of the present invention include various airfoils constructions, such as airfoils and rotor blades having a continuous trailing-edge flap. According to an embodiment, an airfoil is comprised of a load-bearing structure in the forward portion of the airfoil; a skin to maintain the airfoil shape; a tapered composite structure having one or more actuators extending from the load-bearing structure toward the trailing edge, and joining the skin in the vicinity of the trailing edge; and a core extending from the load-bearing structure connecting the tapered composite structure to the load-bearing structure. In this airfoil, the tapered composite structure tapers from being relatively thick near the core to being relatively thin near the trailing edge. And the one or more actuators are configured to deflect the trailing edge so as to deform the shape of the airfoil cross-section.

Abstract: An inflatable antenna has a plurality of inflatable tori including a first toroidal member and a second toroidal member arranged one radially inward of the other. A front membrane having a reflective coating is attached to the plurality of tori to form a front reflective surface. A rear membrane is attached to the plurality of tori and provides a rear support surface. The inflatable reflector is lightweight and compact and can be easily inflated to a desired shape.

Abstract: One or more plastic funnel sheets, attachable to any type of ceiling structure, are positioned and attached beneath each drip location. The funnel sheets each have flexible tubing networked together and fed into a special receptacle for temporary storage of the collected fluids. The receptacle has a gauge which indicates fluid depth in the receptacle.
