The fixed land-based magnetic test

The fixed land-based magnetic test facility of the Krylov Centre is a unique experimental tool for research studies on ship magnetism and magnetic signature management:

• Sumulation of latidudinal zones up to ±6•10^–5 T (vertical component) and up to ±4•10^–5 T (horizontal component);
• Dimensions of uniform measurement zone 2×2×2 m with error less than 1 %;
• Fields: static (up to 10^–3 T), alternating (up to (4•10^–3 T).

An electrolytic test tank

The static electric field in marine environment is simulated in an electrolytic test tank made of dielectric material measuring 2.7×1×1 м;

Ship electric signature simulation test rig

is designed for studying electric models simulating the electric field in sea water and electric signature management systems.

Stratified test tank

is used to study the processes in the media of non-uniform density and interaction of objects with stratified sea medium.

Test tank dimensions: 6×2×2 m;
Temperature gradient: from 0 to 1°C/cm;
Salinity gradient: from 0 to 10 ‰/cm.
