摘要
针对常规布局临近空间飞艇存在的超压控制系统重量大、能耗高等问题,通过借鉴南瓜型高空长航时气球的工作原理,提出了一种新型的省却了副气囊和超压控制系统的临近空间伞张式飞艇概念,该飞艇主要由一种能随气囊内外压差变化实现自主变形的伞张式气囊组成。针对伞张式气囊,通过开展气囊结构概念设计、气囊原理样件研制和地面原理试验研究,验证了伞张式飞艇气囊结构原理的可行性。研究结果表明,临近空间伞张式飞艇气囊结构原理上基本可行。
For the problem encountered in the design of near space airship＇s overpressure controll system,a novel near space umbrella-like inflated airship concept which omits ballonet and overpressure controll system is proposed by applying the principle of the pumpkin-like ultra long duration balloon（ULDB）.The airship composed of umbrella-like inflated envelope can deform automatically as the differential pressure changes.The principal feasibility of envelope structure of the umbrella-like inflated airship has been validated through principal design of the umbrella-like envelope structure,development and trial-manufacture of the principle sample,and ground principle test.The analysis result shows that the envelope structure of umbrella-like inflated airship is conceptually feasible in conception.
