Abstract
A major goal of the hydraulic ram survivability program
for aircraft fuel tanks is the development of an economical
computer code which accurately predicts the pressure in the
fluid, the response of the tank walls, and the crack damage
to the tank due to a ballistic projectile. This study compares
the tank wall response predicted by the recently modified
SATANS code with the data from studies performed by
California Research and Technology, Inc., the Naval Weapons
Center, and the University of Dayton Research Institute. Good
agreement among the results is obtained for this phase of the
study. Additionally, a comparison of the predicted crack
length in the entry wall of the tank using Fahrenkrog's criterion
and SATANS ' predicted circumferential stresses is made
with actual crack lengths from a test performed by the University
of Dayton Research Institute. The predicted crack lengths
were in excellent agreement with the actual crack lengths.
