摘　　要：为了解双囊体飞艇布局方式对飞艇气动特性的影响,分别建立了常规单囊体飞艇和双囊体飞艇两类几何模型和气动模型,从攻角变化和囊体距离变化两方面对布局方式的气动特性进行了对比分析。研究结果表明:双囊体飞艇较单囊体飞艇有更大的升阻比;双囊体飞艇在囊体不再相交之前,迎角小于14°时,气动性能达到最优。研究结果可为大型混合式飞艇的发展及研制提供有益的参考。In order to study the aerodynamic performance of conventional single-and double-envelope airships,the geometric and aerodynamic models are established.Based on the models,the aerodynamic characteristics along with the angle of attack and the distance between envelopes are performed for different kinds of airships.The results show that the airships with double-envelope possess better aerodynamic performance comparing with that of single-envelope airship.Moreover,airships with double-envelope could exhibit the optimal aerodynamic performance before envelopes intersect.The results can also provide references for the development of large airships.
