Effect of Side Wind on the Directional Stability and Aerodynamics of a Hybrid Buoyant Aircraft

Effect of Side Wind on the Directional Stability and Aerodynamics of a Hybrid Buoyant Aircraft

Directional stability characteristics explain the capabilities of a hybrid buoyant aircraft’s performance against the side wind, which induces flow separation that is chaotic in nature and may lead to oscillations of the aerodynamic surfaces. A numerical study is carried out to estimate the effect o...
