RESULTS
te yield value realized in Shot 3 was too low to give any significant results. The highest pressure region in which vehicles were
located was=7.48 psi.
At this pressure level damage to vehicles was
light. The.damage and the displacements are tabulated in Table B.1.
The pressurevalues measured at each vehicle station are shown in
Tebdle 3.1.
Two of the "q" gages at 10,900 feet and 13,800 feet did
not function.

The pressure region to which vehicles were subjected ranged from
8.3 psi to 58 psi.
severe.
Within this range, damage varied from light to
Mont of the vehicles were completely demolished.
As in previous snotvs, venicles in side-on orientation sustained
more damage than the vehicles in face-on orientation. In the region
of over-kill, where vehicles are-totally diamembered, the vehicles
placed face-on were not damagedto the extent of the vehicles placed
side-on (note difference in photographs in Appendix C). An observa-
tion of unusual damage was madeat Station 180.20.
The vehicle in
face-on position was displaced 200 feét; yet the only damage incurred
was to the two front wheels. The box and steering column were intact,
so it may be assumed that this vehicle/did not roll. Fowever, it 1s
not certain whether the vehicle was picked)lup and hurled through the
air, landing on its two front wheels, or whether the vehicle slid.
Two vehicles at Station 1U0.21 were blown into the lagoon, ani
damage cculd not be evaluated. If the damage could be evaluated, this
result would not be valid, since damage would certainly be different
if the vehicles were hurled against a ground surface.
Water waves did wash over the nearer positions to ground zero and
possibly inflicted additional damage to vehicles at these stations.
Beyond Station 180.19 there appeared to be no damage. resulting fram
water-wave action. From the terrain features noted, it was reasonable
to assume that water waves did not wash over beyond Station:“280.19.
The damage evaluations and the displacements are listed in
Appendix B, Table B.2.
The static pressures and dynamic pressures as
measured are shown in Table 3.2 and plotted in Migs. 3.1 and-%3, 2;
respectively.
The plot of static pressure data generally fits the
predicted pressure-distance curve, if a yield value o 1.7 MP is: lised.
The dynamic pressure curve of Fig. 3.2 was obtained from the predicted
pressure-distance curve of Fig. 3.1 by the use of Equation 2.1.
