used to carry a sudsy reflective sphere to 50,000 feet pressure altitude. The
sphere is to be inflatmdtes full as possible on the gremnd and vent moms gas

mast operate at different pressures. It is vital that the twestpteer inch diameter
sphere be used with the cylinder equipped with the 20 Mb relief valve end that the
forty.four inch dimeter sphere be used with the cylinder equipped with the eight
mb relief valve. Pailure to do this will probably cause the tortrotour inth diameter
sphere to burst and the twenty-four inch diameter sphere to be slack on socent.

LAUNCH INSTRUCTIONS FOR RADAR SYSTEM
INTRODUCTION: A forty-five foot long one mil "Mylar" cylinder balloon
IS to be used to carry a radar reflective sphere to 50c115404,feet pressure
altitude. The sphere is to be inflated as full as possible ag the
ground and vent excess gas to the haw balloon as they ascend. 'Act alti-
tude both balloons will be superpressured.
DESCRIPTION: Two complete systems (two cylinders and two spheres) are
included. Since the spheres are of different diameters the venting
valve in the two cylinders must operate aCdifferent pressures. It is
vital that the twenty-four inch diameter sphere be used with the cyltnder
equipped with the 20 mb relief valve and that the forty-four inch diameter
sphere be used with the cylinder equipped with the eight mb relief valve.
Failure to do this will probably cause the forty-four inch diameter sphere
to burst and the twenty-four inch diameter sphere to be slack on ascent.
_
DIRECTION FOR USE: Since the free lift is a critical factor in this system
it should be prepared for launch under near zero wind conditions.
I. System with twenty-four inch sphere
I. Lay out ground cloth.
2. Pull balloon from bag stopping at the rope tied around the
balloon. Tie this rope around top of polyethylene bag with
remainder of balloon in bag.
3. Remove cap from inflation fitting and attach inflation hose
from hydrogen cylinder. Add gas until system is in exact
equilibrium. Care must be exercised not to over inflate, but
nevertheless bring the balloon to equilibrium with hose removed
and inflation cap replaced.
4. Remove remainder of balloon from polyethylene bag to expose
bottom fitting for attachment of sphere.
5. Inflate sphere as completely as possible (but not hard) and
attach to cylinder fitting making every effort to lose as
little gas as possible from the sphere during this process.
Leave white tape and weight on end of sphere balloon fitting.
6. To launch remove rope tied around cylinder balloon.
II. System with forty-four inch sphere
I. Lay out ground cloth.
2. Pull balloon from bag stopping at the rope tied around the
balloon. Tie this rope around top of polyethylene bag with
remainder of balloon in bag.

3. Inflate sphere leaving white tape and weight on fitting and
put tape over end of fitting to retain gas. Tie fitting to
rope holding polyethylene bag and remaining cylinder balloon.
4. Remove cap from inflation fitting and attach inflation hose
from hydrogen cylinder. Add gas until system is in exact
equilibrium. Care must be exercised not to over inflate, but
nevertheless bring the balloon to equilibrium with hose removed
and inflation cap replaced.
5. Remove remainder of balloon from polyethylene bag to expose
bottom fitting for attachment of sphere.
6. Remove sphere from previous position and attach to bottom of
cylinder.
7. To launch remove rope tied around cylinder balloon.
