The development of stratospheric airship is a huge and complicated system engineering.The key issues and technical difficulties encountered in the technology development and engineering application should be solved by new ideas and innovative solutions.This paper summarizes the development and current status of the near stratospheric airship in China and abroad,and mainly describes the technical verification test flight.In view of the five aspects of the stratospheric airship overall layout,ultra-pressured envelope,energy system,flight control and fixed point landing,the technical difficulties,research status and development trend are discussed.From the perspective of engineering,this paper discusses the feasible solutions and some attentions of related technical problems.
