Automatic Trim System for Unmanned Underwater Vehicle (English)
Abstract [en]

This master thesis work was done at Saab Underwater Systems AB, a company at the cutting edge of underwater technology. Here torpedoes and other underwater vehicles are developed and manufactured. The major customers are navies of different countries, mostly the Swedish navy.

The aim of this master thesis is to develop, construct and evaluate an automatic Trim System for Unmanned Underwater Vehicles. The task of the system is to change the position of the centre of mass and the vehicle’s total mass or volume. A system like this gives more opportunities like improved low speed properties, manoeuvre ability and energy consumption.

Different ways to make this change of total mass and position of centre of mass has been discussed and a choice has been done. A system of chosen concept has then been developed, constructed and evaluated. A part of big importance in this report is the work with simulations to predict the performance of the system and its behaviour. Other big parts has been to find suiting components and to develop the control electronics of the system.
