为了对常规单囊体飞艇和混合式飞艇各自的性能特点有更清晰的认识，分别设计了某常规飞艇和混合式飞艇的总体方案，建立了两类飞艇的分析模型，并从气动特性、浮升特性、重量特性、续航特性方面对二者的综合性能进行了比较和分析。研究表明：在体积相同的情况下，虽然混合式飞艇在阻力特性方面不如单囊体飞艇，但由于混合式飞艇动升力较大，并可以借助动升力来平衡燃油的消耗，且有效载荷大、载油量大、可操纵性好，更有利于长航时飞行。研究结果可为我国开展长航时和大载重飞艇研制提供一定的设计参考。
為瞭對常規單囊體飛艇和混閤式飛艇各自的性能特點有更清晰的認識，分彆設計瞭某常規飛艇和混閤式飛艇的總體方案，建立瞭兩類飛艇的分析模型，併從氣動特性、浮升特性、重量特性、續航特性方麵對二者的綜閤性能進行瞭比較和分析。研究錶明：在體積相同的情況下，雖然混閤式飛艇在阻力特性方麵不如單囊體飛艇，但由于混閤式飛艇動升力較大，併可以藉助動升力來平衡燃油的消耗，且有效載荷大、載油量大、可操縱性好，更有利于長航時飛行。研究結果可為我國開展長航時和大載重飛艇研製提供一定的設計參攷。

To make the performances of conventional ellipsoidal airship and hybrid airship more clear, firstly, the overall design of a conventional airship and a hybrid airship are accomplished respectively, then the analytical models of the two kinds of airships are established, both comprehensive performances of aerodynamics, lift, weight, duration and maneuverability are compared and analyzed. It is found that drag of hybrid airship is not as good as conventional ellipsoidal airship in the case of same volume, but hybrid airship＇s dynamic lift is large, and can compensate the oil consumption. Furthermore, the characteristics of heavy payload, large oil-loaded, fine maneuverability of the hybrid airship are fit for the long endurance flight. The study results can be of certain references to the development of heavy-load airship.
