A pre-study on implementing self-sealing techniques in the fuel tank of the Combat Vehicle 90 : BAE Systems Hägglunds
This project is aimed towards the defence industry, resulting in a lot of information being classified. This report is therefore written in a way so no sensitive and secrecy information is revealed. In today’s model of the Combat Vehicle 90 (CV90), there is no self-sealing ability implemented into the fuel tank. When a projectile penetrates the fuel tank walls, the fuel will leak out. This master thesis is a pre-study to see what kind of available self-sealing applications there is on the market today and how these can be implemented into the fuel tank of the CV90 in order to make the fuel tank leak proof if damaged.An extensive research phase has been conducted where theory regarding projectiles and ammunition, damage prevention, damage management and fuel tanks has been gathered. The theory part of the project is constructed with a top down philosophy where the fuel tank of the CV90 is in centre. The theory chapter first focus on the threats present in a war zone. The next step is to prevent damage from happening by designing and dimensioning the CV90s fuel tank armour with the help of STANAG 4569 protection levels. If the armour is not sufficient enough and damage occurs anyway to the fuel tank, management of the damage can be dealt with by using different self-sealing techniques. For the viewer to understand the concept of a fuel tank better, theory has been gathered in the field of fuel tanks regarding fuel slosh, explosive combustion, fuel cells used in racing, history of self-sealing fuel tanks and different technical solutions in the form of patents and self-sealing applications provided by companies on the market today. The project is a pre-study in a Research and Development process. The process is divided into a knowledge part and a result part, where the knowledge part is the most extensive, consisting of planning the project, understanding the task and the problems in the project, research around the task and evaluating the researched material. The research consists of analysing the self-sealing ...
