飛行船船体による動的揚力発生法の再評価

抄録

In order to improve normal maneuverability of airship, hybridization is conceived in which a part of the gross weight is supported by dynamic lift. The simplest way is to utilize the dynamic lift of the gas envelope itself. Someone suspect that excessive induced drag happens due to the low aspect ratio. This problem is investigated here, being compared with the case where an additional fixed wing is adopted. Conclusively use of the dynamic lift due to the gas envelope itself is not necessarily inefficient, because of no additional structural weight.
