自从19世纪50年代载人飞艇升空以来,飞艇的发展经历了齐柏林大型硬式飞艇空袭伦敦、开设南美定期航线、齐柏林伯爵号飞行世界一周等创造光辉记录的黄金时代。但是,在现代航空运输方面,飞艇已经让位于喷气机、直升机等所谓HTA(Heavier-Than-Air)航空器。那么,飞艇能否利用现代先进技术重新武装,满足多样化的运输需求,成为一种产业呢? 相似文献

Structural Performance Evaluation Procedure for Large Flexible Airship of HALE Stratospheric Platform Conception 总被引:1,自引:0,他引:1
Basic loads applied on the airship envelope were analyzed.The resultant forces,the static bending moment and the dynamic bending moment were formulated.Based on classic linear elastic membrane theory,the procedures to calculate the minimum pressure were proposed for sufficient rigidity evaluation.The limit load capacity was further investigated,and the related formula were developed.Finally,the stress and internal forces analysis was carried out for cylindrical and non-cylindrical approximations of envelope hull of airship.The present research is very valuable to the overall preliminary design of airship and further research. 相似文献
