Title: Aeroelastically Tailored Wing Structures (ATWIST)
Agency: NASA
Contract: NNX13CL20P
Award Amount: $124,973.00


Aurora will develop a novel composite sandwich structure that is capable of providing a coupled bending-torsional stiffness with nonlinear elastic effects, capable of achieving a tailored aeroelastic response over a wide range of flight conditions. Such a structure will make use of an additive manufactured core with highly tailored and optimized cellular substructure. The cellular structure will be functionally graded in the spanwise and chordwise directions to provide a coupled bending-torsional stiffness response. Fiber reinforced composite facesheets will provide strength. Utilizing the core structure to couple the bending-torsional stiffness of the composite may allow the composite to remain balanced and symmetric, thus avoiding induced stresses and/or warping during manufacturing.
