The application of bionic design in the field of UAV has gradually shifted from functional optimization to morphological innovation. SHADOW is inspired by the mako shark, a natural example of speed and fluid efficiency, and its musculoskeletal structure provides a natural optimization template for drone aerodynamics. The swept-wing layout refers to the high-speed penetration characteristics of the fighter, combined with the low-altitude stability of the four-axis power system, and aims to further improve the resilience of small UAVs in complex environments.
