MWORA&D I FOR THE RECORD
Destructor System.
14 October 1958
1. On 8 October 19581
45 connections failed, however, it was felt that the method of crimp-
ing the.end cap on the branch line was at fault. In the following
tests the crimp was always placed between the reference lip and the
open end of the cap.
2. Five main lines (each approximately 55 feet in length) were
layed out on the ground and 20 branch lines were attached to each main
line with the plastic Tee connectors. (One main line bad 21 branches.)
A was placed on the end of each branch.
Results: One failure occurred and the end cap had the same
flowered appearance as in the.previous failures.
Thus, 100 out of 101 were successful, however,
it is felt that at least 50 more Tee connectors
should be tested and not fail before this type
of connections is considered reliable.
3. To determine what effect the charge in the end
caps has, 4 loaded and 5 empty end caps were crimped on dummy primer
cord branches.
Photo 1 shows loaded end caps. The base on theone cap was not
shattered, but the other three had a flowered appearance.

Photo 2 shows the empty caps and it can be seen that they were
only crushed. This indicates that the detonation of the PETN charge
is responsible for the flowered appearance of the failures. The
question now is to determine why the branches are not propagating
when the PETN in the end cap detonates. One cause could be that
enough PM falls out of the primacord when it is cut that an air
gap is left.
4. Ten end caps were picked at randcxn and weighed to determine
the uniformity of the 1/8" PM base charge. The results were:
