Abstract: Integrated pultruded composite profiles such as rotor wings and blades for electric vertical take-off and landing aircraft, light helicopters, wind turbines, and other rotor wing applications and integrated design and processing methods for making same are disclosed. The present invention provides a plurality of web ribs for stiffening and supporting an outer skin which can comprise fabric plies, a metallic skin, or a thermoplastic composite skin. A process and method to continuously pultrude integrated composite airfoil profile with variable aerodynamic twist is also disclosed. Utilization of a stranded metallic wire rope that enables the leading edge weight to be continuously in-situ fed into the pultrusion process and effectively retained in the pultruded product is also disclosed. Utilization of fiber reinforcement impregnated with matrix resin that is loaded with high density powder for the leading edge weight is also disclosed.

Abstract: The invention entails apparatus for mounting a payload, such as a warhead, to bulkheads carried by munitions. The apparatus comprises fore and aft bulkheads depending from the munitions, each of the bulkheads having a substantially centrally located opening; bulkhead attaching structure carried by the payload and engaging at least one of the bulkheads, and at least one fastener carried by the bulkhead attaching structure and engaging both the payload and the bulkhead attaching structure. In one embodiment, the bulkhead attaching structure is an annular ring element disposed about and secured to the aft end of said payload. The ring element includes a first annular portion of a first diameter, and a second aft portion of a second diameter, the first diameter of said first portion being smaller than the second diameter to accommodate annular portions of the aft bulkhead. In a second embodiment, the bulkhead attaching structure comprises a step element carried by the payload, which abuts the fore bulkhead.

Abstract: Apparatus for separating aerodynamic objects from an aerodynamic vehicle includes a first element, aerodynamically configured to create nose-down pitching moment, mounted to the object surface, a second element mounted to the first element and projecting into an oncoming airstream such that when enabled, the passing air tears the apparatus from the surface which otherwise supports it. The first element is a body designed to be conformal with the object surface to which it is mounted, and includes a forward end projecting into the oncoming airstream and a rearward end, and is secured to said object surface at the rearward end thereof. A flexible gasket is interposed between the first element and the object surface. The second element comprises a forward end directed toward the oncoming airstream and a rearward end, with the second element being mounted to the first element at the rearward end of the second element.
