Project 1.5 - Drag Characteristics of Various Shapes ~ J, J, Meszaros
VEHICLE RESPONSE STUDY
OBJECTIVE
The vehicles were exposed on this shot to obtain information which
would supplement data from Operation CASTLE,
Due to weapon difficulties
for one shot and lack of land area for the second shot, the data obtained
on that operation were considered insufficient to make concrete conclusions,
This was especially true for transition from light to severe
damage levels,
TECHNIQUE
Ten vehicles (truck, 7 ton, 4 x 4, utility, Model MB - WWII) were
set up at six stations,
from ground zero,
One side-on vehicle wes placed at 6900 feet
Two vehicles were arranged at 83C0, 10,400, 11,700
and 13,800 feet stations; one side~on and one face-on at each station,
One vehicle was placed side-on at 1€,500 feet,
Steel stakes were driven
in the ground at each station to facilitate displacement measurements,
RESULTS
Evaluation of the damage revealed very severe damage to all the
vehicles at the 6900, 8300, 10,400, and 11,700 feet stations except
the face-on vehicle at 11,700 feet,
The four side-on vehicles and one
face-on at 8300 feet were completely demolished,
The face-on vehicle
at 10,400 feet was intact except that the engine was thrown out,
The
face~on vehicle at 11,700 feet and side-on at 13,800 feet were moderately
damaged,
The face-on vehicle at 13,800 feet and side-on vehicle at 1€,500
