Abstract

In the last few decades, interest in high speed marine vehicles, both in civil and military marine transportation, has motivated the marine engineering community to develop new configurations [1]. Among these, the ‘aerodynamic alleviation concept’ [2] consists of using one or more aerodynamic surfaces to alleviate the weight of marine vehicles. The advantages are: lower hydrodynamic drag better damping of heave and pitch accelerations. At Cranfield University a research programme to study AAMV started five years ago. Firstly, an AAMV equilibrium attitude model has been developed and implemented in MATLAB [3]. Similar to the Savitsky model for planing craft [4], this model is able to estimate the attitude of a given AAMV. Secondly, the vehicle stability has been studied by developing a specific system of equations of motion, using a small disturbances assumption [5]. This article presents a possible AAMV configuration that illustrates the potential of such configurations and how mathematical models can be used as design tools.
