To balance the aerodynamic performance of aerospace vehicle in wide-speed flight, it is inevitable to adaptively adjust the aerodynamic profile of the morphing nose cone according to different flight environments. Honeybee abdomen can adjust the configurations according to the different environments, and the distributed muscle drive is the key for the flexibility and efficient drive of honeybee abdominal movement. Thus, the muscle distribution of honeybee abdomen is observed through stereoscope. Drawing inspiration from the unique muscle distribution in adjacent abdominal segments of honeybees, the morphing unit mechanism of 4-RPU is obtained, and the kinematic analysis is conducted to study the kinematic performance. In addition, a structurally symmetric morphing nose cone driven by the distributed morphing unit mechanism is designed, and the deformation ability is further verified. This research provides the reference for the structural improvements of the morphing nose cone and will promote the development of aerospace vehicle.
