Project 1.1] - Basic Plast Measurements - J. J. Meszaros
The objective of the participation of Project 1.1 on the
\e
a(2:) was to document the propogation of a blast wave
from @ megaton yield surface burst.
A total of 25 pt gages and 9 q gazes were installed for Zuni.
Two blast lines were instrurcntcd.
There were 14 pt gages and 4 q
g4eces on the Eninman Complex while on Tmirikky Island,10 pt gages
and 5 q gares.
There was 1 pt gare on Enyu for Water Wave Studies,
There was considerable damage both to the pt and the q mounts.
Threc pt mounts were blown out and the gares were not recovered.
Six of the q mounts suffered from severe to light damage.
Tro were
blown out completely while the other four were bent back at varicus
There was a precurscr wave recorded on both blast lines.
The
recorded values of peak overpressure are plotted in Fig. 1.1-1.
The values at the close in stations show a deviation from the pressure distance curve plotted from the pressure values predicted for
a 3.5 MT yield for a pocr surface.
The pressure time recerds from
beth blast lines show distorted wave shapes similar to those assceiated with @ precurser,
Although the wave shape is distorted, the
peak overpressure values beyoni 8,070 feet follow the predicted pressure distance curve for a yield of 3.5 MT at zero height of burst over
a poor surface.
There is a wide spread between the pressure values
recoried at 7020 feet on Eniirikku and 6900 feet on Eninman Complex.
It is believed that this difference is real and not a gage error.
If
the data points from Pniirikku are eccnnected a precursor type pressure-
