III g) c·onclusions E:nd Recommendations.
It is believed that a balloon can be kept at nominal constant
altitude between 10 and 20 km. for six hours using a non-extensible
envelope vri th the addition of a balla.st val vc to kee9 the· belloon near
its :)ressure altitude. The flying of a bal.loon thus equipped is our
main objective. The work to date has been primarily preparatory but it
is believed that plastic balloons can be flown in the early summer with a
payload.
Additional work space is urgently needed at New York University
if significant work is to come from this group.
It is believed that the ideal launching area for balloons of
this type is Lehigh University, Bethlehem, ?a. as long as this is feasible,
For large balloons it is believed that t~e NavY peo}le at Lakehurst can
best facilitate the launching. Calm winds are essential for actual launching.
Future Work
General Mills is making large balloons from lightweight films
that would meet our specifications with the exception that they cannot
take any internal pressure. It is believed that their balloons should be
investigated as General Mills appear to be the best source of supply for
large balloons. An order ~11 be placed with them as soon cs they furnish
a. quotation.
As a stop-gap device before these might arrive it is planned to
fly two 35,000 cu.ft. racing tr?e as well as the 2 Japanese balloons from
Dakehurst, U. J. carrying j)ayloacis with heavy duty power su9plies for the
radio transmitters.
In the meantime, improved clusters of ~teorological balloons
will be flown until larger balloons are available.
