The central problem of a hybrid airship design, the optimum apportionment of the total lift between the static buoyant lift and the aerodynamic lift, is studied. The lift apportionment is carried out for specific lifting-body shape represented by a and . Different flight strategies have been analyzed. Optimal configurations have been obtained for various flight-time constraints and cruise altitudes. The result of the study is a set of hybrid airships with optimal apportionment of total lift along with optimal flight profile. The set has been presented in the form of a design chart, and an optimal hybrid airship can be obtained, corresponding to a maximum flight time and a cruise altitude.
