From this survey and a study or aerostatics, ' ' it appeared that
a non-extensible balloon is highly desirable due to the vertical stabili~
exhibited when such a balloon is full of the lifting gas a A non-extensible
balloon with 'no diffusion or leakage through the walls, which could withstand
a high internal pressure, would automatically remain at the densi~ where
the buoyancy of the fUll balloon equaled the load. In practice, control
devices are needed to offset tqe leakage and diffusion of the lifting gas
and to correct for the motion or the balloon due to diurnal changes or
the balloon's temperature and to correct for vertical wind currents in the
atmosp~ere. It was decided to use a pleatio a• the balloon fabric, since
available plastios have suitable characteristics, and are also relatively
inexpensive as compared to coated fabrics.
The desirable properties to be considered in the selection of a
plastic balloon material area
a. Ease of fabrication
b. High tear resistance
o. Light weight
d. High tensile strength
e. Chemical stability
f. Law permeability
g. Low brittle temperature
h. High transparency to heat redie.tion

fabrics investigated. The date in the table are presented as approximations
because of the great variations of a given prbperty with choice of samples
