There are several modern submarine shape?
Time:
2010/2/1
Modern submarine linear according to the shape of the hull can be divided into three kinds, namely, conventional type, drop-type and transitional type.
Conventional submarines are submarines used in linear before and after the First World War. This side of the submarine similar to the shape and surface ships; order to reduce the sailing time of wave resistance, first to resemble the shape of surface vessels, first; order to make a submarine in a sea storm better airworthiness, first there a great arc ridge and there buoyancy module, relying on buoyancy tank provides buoyancy to improve the submarines immersed in the phenomenon of wind and waves. This vessel type is suitable for surface navigation, but it is detrimental to improve underwater speed.
As the demand for submarines underwater speed of the continuous improvement, people conventional submarine hull forms for a series of improvements. Abolition of modern conventional submarine ridges in the first arc and buoyancy tanks, and the first inclination of the boat in the first cancellation of the straight into the first column.
Drop submarine linear features, is the first cylindrical blunt spindle-shaped, almost all cross sections of the submarine as a circular cross section, Ting Shen start back from the central tapered tail was pointed caudate. Drop submarine underwater resistance is small, will help improve underwater speed, but the drop surface submarine navigation performance poor, easy on the boat in the first wave, but also obsessed with the phenomenon of easy to occur. Some drop submarine navigation performance in order to improve the surface, using the boat in the first buoyancy tank. Transitional submarine is to direct the first and the conventional type of sharp drop-shaped tail of a submarine linear combination of this submarines navigation performance is better than drop-type surface, while the underwater navigation performance is superior to conventional submarines.
