Zusammenfassung:In this paper, a new lifting system for rising of the seabed submerged objects is proposed. The processes of design and building are also presented in detail. Fast-acting, intelligent, easy-performing and portability are most important characteristics of the new system. The required force for most of the existing liftsystems is usually provided by creating a hollow-water volume, or a gas-filled bag, under the water. Based on the Archimedes' law, an upward buoyancy force produces at these conditions. A compressed air capsule is usually used for filling the bag in most of the existing methods. Big and heavy components of those systems cause some operating difficulties. Also, the presence of a frogman is a necessity for those systems. It is obvious that the depth of the presence for a frogman is limited. It is very harmful for a frogman to be present at the water depth of more than about 40 meters without using of the pressure chambers and more safety equipments. In order to deduce the above matters, a new design for a lifting system is proposed in this research. In this system, instated of using a compressed air system, combustion of a solid-fuel substance with a controlled condition and cooling of the gaseous products, provides the required gas for filling the bag. The most important applications of this new system can be where shortening of the operation time is vital, such as at naval, safety and emergency subjects of the marine engineering applications.
