Numerical Analysis of Fuel Tank Penetration Dynamics.
Abstract
The dynamic characteristics of fuel tanks which are penetrated by .50 caliber bullets are examined using a 2-D finite difference computer code. The bullet impacts the tank unyawed; however, tumbling is simulated by changing the shape of the bullet in the calculation to match the drag force and associated energy transferred between a real tumbling bullet and the fuel. Complete penetration of a 15 in. deep fuel tank with 1/8 in. aluminum walls is analyzed in the numerical calculation. The calculation includes a description of the Pressure versus time and radius loads on the entrance and exit walls, Pressure-time histories at various stations in the fuel, Deformation of the entrance and exit walls, and Formation of the cavity in the fuel behind the penetrating bullet.
