A J-2000 neoprene balloon was encased with a nylon shroud and jrovided
with a Taln to penni t gas to escape after a IDI!Illl superpreuure ( 4 ·" ot
water) as exceeded. The balloon in its shroud 1a 1hawn in Figure 12.
Figure 12: Neoprene balloon encased in a nylon shroud
If a "superpressure" balloon ia used, much lesa ballast is required since,
during minor oscillations, the reduction of buoyancy will not cause the bal-
loon to descend as long as the remaining buoyancy is equal to or greater than
the load supported.
!his balloon, and three similar ones (Flights 38, 66, 87), failed to achieTe
any constancy of altitude. All four tailed during the rising period or soon
after the shroud became full. (The balloons were heated prior to release
to re1tD»e elasticity.)
