Abstract
The invention relates to a method and a device for discharging signature free exhaust gas from underwater vehicles, the exhaust gas being a by-product of the production of electric energy in energy converters and being directed by means of pressure into a pipe length through which outboard water is flowing. Gas bubbles of the exhaust gas in the at least one pipe length are reduced using static mixers arranged inside of the pipe length through which water is flowing, with the gas being dissolved by the high turbulence of the fluid. As the exhaust gas is dissolved inside of the underwater vehicle, no gas bubbles that might be located are produced outside the vehicle. Since the working pressure of the method equals the immersion pressure in the pipe, the method consumes only a small amount of energy.
