Effect of two typical wing forms on aerodynamic characteristics of mid-cylindrical airship

Aiming at the problem that the effect of two-typical wing forms on aerodynamic characteristics of mid-cylindrical airship, the aerodynamic characteristics of airship with X-shaped tail and inverted Y-shaped tail are studied respectively. Based on the method of Computational Fluid Dynamics(CFD), the aerodynamic characteristics of airships with the same hull shape parameters are simulated, at an angle of attack ranging from -30 to 30 degrees and angle of sideslip ranging from 0 to 20 degree. The result shows that the mid-cylindrical airship with inverted Y-shaped tail has a certain advantage in reducing hull resistance, compared with the airship with X-shaped tail. The mid-cylindrical airship with X-shaped tail has better ability to provide lift force and maintain hull stability, compared with the airship with inverted Y-shaped tail. The simulation results provide an effective reference for aerodynamic shape design and flight control strategy of mid-cylindrical airship.
