Abstract [en]

In order to improve the performance of the outlet louver for the cooling system used in the Combat Vehicle CV90, the manufacturing company BAE System Hägglunds AB recently came out with a new design.

This project deals with the possible modifications of the new design to achieve a higher performance in terms of air flow resistance without losing any protection capabilities.

18 versions of BAE Systems Hägglunds AB new design were modeled using Creo Parametric 3.0 3D CAD-software. These versions were modeled with respect to the requirement of protection, when several possible threat scenarios  were carefully reviewed and studied.   

The air flow through each one of these designs was CFD-simulated using ABAQUS/CAE 6.14 CFD-code, the pressure drop received in each CFD-model was compared to the pressure drop over the currently used design of the outlet louver. The concept called concept Arrows RD shows the lowest pressure drop, which is nearly 50 % lower than the pressure drop over the original design, showing that the new design could be a reasonable replacement to the currently used design.
