Abstract

Original defects in the envelope material easily torn damage under overpressure, when the stratospheric airship in use. This paper based on linear elastic theory studied the tear strength of envelope material containing initial center crack and proposed theoretical model for this problem. Choose Vectran fiber as a reinforcing layer of stratospheric airship envelope material, Combined with digital speckle method measuring tear strength of envelope materials containing different initial center crack length. Comparative analysis found that the theoretical model applicable to estimate the tear strength of envelope material, that center initial crack width ratio is less than 50%.It estimation error within 5% .It satisfies the requirement of engineering application accuracy.
