volume of the 20-foot cell is about 4300 cubic feet and
its uninflated length is 38 feet. It is made up of 20
gores, heat sealed together in a butt weld. Along the
seams thus formed, a special acetate-£iber scotch type
tape (Minnesota Mining and Mfg. Co.,) is laid to reinforce
the weld and to carry and distribute the load. These
tapes converge to an appendix ring at the balloon bottom,
to which the load harness is attached. By using this
stressed tape design, much larger loads may be carried than
the thin polyethylene alone could hold. To exclude
air entering through the bottom, which is left open, an
external skirt or appendix is added.
Figure l Shows a 20-toot balloon ready to be released,
with an external appendix in position. As the balloon
rises, the lifting gas inside will expand until the balloon
is full, whereupon the excess gas which was needed to
make the balloon rise will be valved out. The full bal-
loon will then float at a level where the buoyancy just
balances the load. It will remain there until buoyancy
is lost by diffusion of the lifting gas, or by cooling,
as at sunset.
Neglecting minor effects, the amount of gas which is needed
to just balance the load at the maximum or floating ele-
vation would also just balance the load at any lower level,
including the surface, al~ugh the balloon would be less
than completely full at such a lower level.
B. Load Limits
For a given lifting gas, the altitude to which a balloon
will rise is determined principally by the load it bears.
Yii th a 20•foot General Mills balloon, using helium, a
payload of 40 pounds will reach approximately 46,000
feet and an 18-pound load will go to about 58,000 feet.
Although the manufacturers recommend keeping the payload
between 18 and 40 pounds, no trouble has been folli~d in
launching loads of as much as 70 pounds (37,000.feet) or
as small as 4 pounds (67,000 feet).
C. Appendices
For·highest altitudes and smallest sunset effects on a bel-
loon, it is necessary to keep air from diluting the helium.
To accomplish this, a check valve is required in order
that helium may be valved when the balloon is full, yet
air not be permitted to enter at any time. An appendix,
consisting of a tube of balloon material, whose length is
about 2 to ~ times its diameter is used for this purpose,
and is supplied as part of the General Mills balloon.
