Low Cost Pultruded Composite Extendable Joined Wing Range Extension Kit with Advanced Aerodynamic Control Technology

"Joined, extendable wings provide attractive aerodynamic, structural and packaging characteristics that increase weapon standoff range while requiring comparatively little pre-launch volume. Cost of current joined wing kits is high. Future designs couldbenefit from more highly automated manufacturing technology and more sophisticated control concepts. The proposed pultrusion process is ideally suited for making low cost, high strength, low signature, high aspect ratio composite wings that will notcorrode during storage. Simple modifications to deployment linkage geometry of the joined wing will take advantage of underutilized storage space on the weapon, allowing increased wing span and aspect ratio compared to current technology, resulting inimproved aerodynamic efficiency (L/D) and greater standoff range. Differential motion of wing deployment mechanisms can be used to provide vehicle pitch and roll control, eliminating two separate actuators and flight surfaces, enhancing reliability whilereducing cost and weight. In Phase I, KaZaK will develop and demonstrate a pultrusion-based technique for making low cost twisted composite airfoils. We have teamed with Dynetics, a firm having considerable experience in design and testing of deployablewings, to perform the aerodynamic modeling of this concept. In Phase II we anticipate preforming full scale wind tunnel and flight testing of the system. Upon completion of Phase I and II, KCI will
