“…Recently, some authors analysed the HRAM phenomenon through the results of intrumented experimental tests. Lecysyn et al [25][26][27] studied the drag and cavitation phases of the hydraulic ram, reporting measurements of the movement and deceleration of a projectile after it impacts a fluid-filled vessel results. Disimile et al [28][29][30] applied a large-scale shadowgraph technique to a fuel tank simulator in order to visualize the pressure waves generated by hydrodynamic ram, and the results were compared to pressure transducer signals; special attention was given to the effect of the succesive cavity implosions.…”

Numerical Analysis of the Hydrodynamic Ram Phenomenon in Aircraft Fuel Tanks

Hydrodynamic Ram (HRAM) is a phenomenon that occurs when a high-energetic object penetrates a fluid-filled container. The projectile transfers its momentum and kinetic energy through the fluid to the surrounding structure increasing the risk of catastrophic failure and an excessive structural damage on adjacent components. It is of particular concern in the design of wing fuel tanks for aircraft because it has been identified as one of the important factors in aircraft vulnerability. In order to study the aforementioned phenomenon, water filled aluminium tubes (to different volume percentages) were subjected to impact of spherical projectiles. This work is focused on the analysis of energies, momenta and pressure contours obtained by means of a previously developed and validated numerical model in order to achieve a better understanding of the fluid/structure interaction problem that takes place during the HRAM phenomenon.

“…High velocity impacts on fluid filled containers are of great interest for different industrial fields such as safety of industrial facilities or road haulage, where containers are commonly used to store fuel or dangerous products. In those cases, an impact in the vessel may produce the failure of the tank and could result in a serious consequences on the environment or even toxic and flammability effects [22][23][24].…”

In recent years, vulnerability against high-velocity impact loads has become an increasingly critical issue in the design of composite aerospace structures. The effects of Hydrodynamic Ram (HRAM), a phenomenon that occurs when a high-energy object penetrates a fluid-filled container, are of particular concern in the design of wing fuel tanks for aircraft because it has been identified as one of the important factors in aircraft vulnerability. The projectile transfers its momentum and kinetic energy through the fluid to the surrounding structure, increasing the risk of catastrophic failure. In the present paper, the commercial finite-element code * Corresponding author. Fax number: 34 916248331. E-mail address:jlpuente@ing.uc3m.es 1 ABAQUS/Explicit has been used to simulate an HRAM event due to the impact of a steel spherical projectile into a water-filled woven CFRP square tube. In order to simulate the fluid-structure interaction, the Coupled Eulerian Lagrangian (CEL) approach is used. Experimental tests which indicate the pressure at different points of the fluid, strains of the walls and cavity evolution for different impact velocities are compared with the numerical results in order to assess the validity and accuracy of CEL technique in reproducing such a complex phenomenon. Also, several numerical impacts at different initial projectile velocities are performed to study its influence in the HRAM phenomenon.

“…As an example of the increasing interest on solving industrial fluid-structure problems, it is worth to mention the recent works of Petitpas et al [32] and Lecysyn et al [23,24] in which a ballistic impact on an industrial tank, filled with a toxic fluid and made of steel, is studied. The authors propose an analytical model to reproduce the behaviour of the projectile on the fluid and study its influence on the toxic liquid ejection and the droplets generated.…”

a b s t r a c t Keywords:Hydrodynamic Ram Fluid-structure interaction Aircraft vulnerability Impact Fuel tank Hydrodynamic Ram (HRAM) is a phenomenon that occurs when a high-kinetic energy object penetrates a fluid-filled container. The projectile transfers its momentum and kinetic energy through the fluid to the surrounding structure, increasing the risk of catastrophic failure and excessive structural damage. This is of particular concern in the design of wing fuel tanks for aircraft since it has been identified as one of the important factors in aircraft vulnerability. Usually the HRAM phenomenon is analyzed considering completely filled tanks, but its effect on partially filled containers should also be taken into account due to the fact that tanks use to be impacted under these conditions. In the present paper, the commercial finite element code LS-DYNA has been used to simulate an HRAM event created by a steel spherical projectile impacting a partially water-filled aluminium square tube. The ALE formulation is employed to reproduce the event. Experimental tests which indicate the pressure at different points of the fluid, displacement of the walls and cavity evolution for different impact velocities, are compared with the numerical results in order to assess the validity and accuracy of the ALE technique in reproducing such a complex phenomenon.
