Flight Sequence
All pose cone functions, which are controlled by an electrical tiner
located in the aidsection between the second-stage rocket and the nose cone,
are actuated by explosive squibs.
The first aose cone function is ejection of the wind screen and sidevest ports just before entry into the cadioactive cloud,
The vent ports are
blown out radially by squibs acting against pistoas attached to the inside
face of the ports.
ring.
The wind screen is held in place by a four-section split
The sections are first assembled in pairs.
Ome section of each pair
has a cylinder block containing a squib peraanently actached to one end,
The other secrion has a piston on one end which fits into the cylinder block
attached to the first section; the piston is locked to the block by a shear
pin.
These mo pairs are thea fitted around the aose cone-wind screen junc~
tion and are bolted together.
when the squibs are detonated, the lock pins

force.
A compressed spring then tilts ‘up one side of the wind screen which
is separated by the centrifugal force of the Tocket's spin (3 eps) abour its
own axis.
