Abstract: A multi-mission/purpose ground-effect craft is provided which is derived from a common modular platform which includes a hull; an inner floor structure adapted to be installed over the hull; a body adapted to be attached to at least one of the top surface of the hull and the inner floor structure, such that a interior compartment is formed thereinside; a tail wing assembly adapted to be attached to the aft end of the body; a forward nose cowl adapted to be attached to at least one of the forward nose portion of the hull and the forward body portion of the body; a windshield integrated into the forward end of the body; at least one door assembly integrated into the left or right body side; at least one window assembly integrated into the left or right body side; a propulsion system integrated within the aft end of the body; and a retractable skirt attached and draped from the outer or inner perimeter of the hull.

Abstract: An exhaust gas purifying system and a method for purifying exhaust gas of combustion engines. The system includes a hollow casing, a converter chamber disposed within the casing, spray nozzles for spraying a scrubbing liquid into the converter chamber for forming a moisture-saturated exhaust gas in order to remove pollutants dispersed in the exhaust gas and purifying the exhaust gas, a cooling container disposed within the casing and defining a cooling jacket enveloping the converter chamber for cooling thereof, a primary circulating reservoir fluidly connected to the converter chamber for receiving the moisture-saturated exhaust gas and separating the purified exhaust gas from a waste liquid and for cleaning the scrubbing liquid from the pollutants dispersed in the waste liquid for reuse, and a secondary circulating reservoir fluidly connected to the primary circulating reservoir for receiving the cleaned scrubbing liquid and supplying the scrubbing liquid to the liquid spray nozzles.
