Fig. 5.4--Collection efficiency of 2OQ-mesh screen at azbient condi-
tions for 160,000 feet. Spherical particles are assumed fo have a
specific gravity of five. Eficiency is based oa flow in the free
Stream through the noraal screen area.

Size.
Maximo sazple size may be computed by use of the sam
equations are were used for Teak.
It will be recalled chat the radius of
the Orange cloud was expected to
debris should be gaseous rather than larger than 1/2 aicron, only about 4o
percent of this amount would be collected.
In either case, it was appurcnt
that if che sampler struck the cloud ao adequate sazple would be collected.

Results and Analysis
No sa=ples were obtained on either Teak or Orange shorts.
On Teak shot
a ocmber of aeasures, including lighter rocket fins, had been enployed to
achieve greater than design alcitudes.
Apparently these fins failed during
or after second-stage burning, and the samplers fell within a nile of the
launcher.
lLronically, had they flown successfully, they probably would mc
have had a chance to sazple, since cetonation was about 35,000 feet norta
of the intended position.
