Effect of a Circular Slot on Hybrid Airship Aerodynamic Characteristics

This numerical study reports the aerodynamic properties of a hybrid airship. The airships were designed by combining two semi-ellipsoids with semi-discoid as base model. From model, three different geometrics identified to their characteristics. A circular slot was provided between pressure side and suction objective this realize flow behavior, characteristics, stability such slotted flying vehicles. Interestingly, results imply that lift coefficient increases an increase in angle attack for configurations; is because separation delayed due opening, which turn energies from high-pressure region bottom through slots. stall 50 degrees, 10% more than Aerodynamic characteristics are discussed based on surface pressure, lift, drag various airships.
