Flex-Skins Using Cellular Cores (XSCL)
Agency / Branch:
DOD / USAF
Consistent with the solicitation, the top level program objective of this STTR is to demonstrate the viability and benefits of morphing wing skin designs incorporating cellular cores with tailor-able geometry and material properties. NextGen Aeronautics and Penn State University plan to build on our Phase I work and propose to mature our concepts and designs for a shear-morphing skin to a TRL of 5-6 in this Phase II effort. The NextGen/PSU program, indicative of our technical approach, is entitled "Flexible Skins Using Cellular Cores (XSCL)." In Phase I, the NextGen/PSU team focused on laying a strong analytical foundation for developing optimal designs as well as investigating design approaches to reduce manufacturing complexity and actuation force requirements while simultaneously reducing the panel weight. We developed a novel, hybrid core design consisting of closely-spaced, long flexible strands with hexagonal cells in the central region, connected to stiff members in the perpendicular direction. In Phase II, we will pursue an iterative design-built-test approach and address optimization of the panel at multiple levels - core, core with attached face-sheets and boundary elements, and large panels. The final milestone in this program is the test of large, integrated panel under realistic operational loads.
