A variety of aircraft morphing technologies have been investigated and represented by various researchers in the public domain. The morphing wing concepts involved the modification of aircraft wings during the in-flight course. Most of the technologies/concepts were based on biomimicry, where wing aerodynamic performance improved due to the change in wing shape. Here we describe a novel concept where in the flow parameters of airfoils arranged in configurations are investigated. The flow parameters are investigated using the numerical simulation tool ANSYS. A 2d flow simulation is performed using a Fluent solver to evaluate the flow configuration of the airfoils arranged in different configurations. The first configuration of airfoils is named a base, wherein the airfoils are arranged at zero angles of attack. The other two configurations are arranged by increasing the angular position of airfoils i.e., 15, 30, and 45 degrees. All these configurations are aerodynamically investigated at different sub-sonic speeds.

3D printing technologies have helped researchers fabricate cellular structures and have lightweight and desirable mechanical properties. One such structure is called “auxetic” structures. “Auxetics” is the term used for structures that exhibit a negative Poisson’s ratio (NPR) and offer a wide range of wide range of potential applications in automotive, aerospace and military industries due to their great load-bearing capabilities in association with excellent energy dissipating performance. PLA (Poly Lactic Acid) material is used to 3D print eight different unit cell design. For each unit cell design with three different core thickness of 1.00 mm, 1.50 mm and 2.00 subjected to projectile impact with 10J of kinetic energy were studied by means of explicit nonlinear finite element simulations using LS-DYNA. Studies were carried out. The energy absorbed by the sample, contact force and projectile kinetic energy time history are compared and the damage on each sample is also compared. It was found that the Chiral unit cell absorbs the max energy and have less damage compared to other unit cell design.
