Study of Submersion of a Body Equipped with Buoyancy Engine with Account of Density Profile and Hull Compression
This paper contains an analysis of submersion of a body, equipped with buoyancy engine, based on a simplified mathematical model, accounting for depth-wise density profile and hull compression.At first, under assumption of uniform density profile and incompressible hull, there are considered phases of acceleration, constant speed and deceleration.Analytical solutions for accelerated and decelerated motion are obtained assuming instantaneous change of buoyancy, numerical results feature more practical case of finite time of buoyancy change.For a given depth corridor and estimation is made of full time of submersion.In the second part of the paper account is taken of a non-uniform density profile and hull compression.It is shown that for some density profiles there may occur hanging modes for which the body performs small-amplitude damped oscillations around a certain submersion depth.
