Power-off static stability analysis of a clean configuration of a hybrid buoyant aircraft

In the present study, the static stability of a hybrid buoyant aircraft is estimated using a panel method to solve the potential flow about the aircraft’s components other than the voluminous fuselage. A viscous flow solver was used to compute the flow over the fuselage to obtain the stability coe...
