For the acceleration-tests, a flight-ready nose cone assembly was
separated into two sections at the filter joint.

Both sections were placed

on a spin table in the deceleration plane and the load was raised to 50 g's
and held there for one minute.

No failures occurred.

The sections were

then placed in the acceleration plane and the load was again increased to
50 g's and maintained at that level for one minute.

The programmer

started its functions at approximately 15 g's, continued to operate properly
and no failures occurred.

The test was then repeated using the nose cone

which had been vibration tested and the results were the same,

The four

tests showed that the sampling cone design was entirely compatible with
the anticipated environmental conditions,

Beginning on 17 July, further testing of possible sources of leakage
in the sampling cones was conducted at the Morris Dam Small Calibre
Range, Azusa, California, which is a facility of the U. S, Naval Ordnance
Test Station, Pasadena, California.

Ten assemblies were dropped into

the water at various angles and with various modifications.

The first 8

tests were carried out by dropping the assemblies from a height of approximately 32 feet at angles of 75° and 90° with the breathe hole left open.
Other tests included drops of cones attached to parachutes from 100 feet,

free-fall drops with the breathe hole closed, and parachute drops with a
neoprene boot on the forward seal of the nose cones.
