See this theme, I want to say only: "Official concubine is not done! " hole of this problem head leaves is not general big!
In period of World War II, if submarine can choose the likelihood to launch torpedo in surface, calculate fire Zhu Yuan more easily so.
Well-known, submarine is support adjusts buoyancy position to the affusion inside ballast water cabin and catchment, manage submergence and rise, rely on the attitude in operating helm face to control water, this principle that flies in sky with the plane is similar, but the density of water is ambitious at air, it is very slow that so the attitude of submarine is adjusted, be in especially period of World War II, so submarine moves ability not to have law and photograph of surface naval ships completely compare in the machine of underwater, differ the act that establish hangs down in your water that finish, chaser is lost early to your head played greatly. And, submarine underwater admires Fu have certain limits, although say standing is a likelihood to hang down in water from theoretic submarine, but if submarine underwater vertical use up all one's resources is too great,feasibility condition is, bring about control be no longer in force probably, with the rear gadarene means sinks directly bottom. And hang down establish condition to fall how to be controlled adjust shoot to with course, this difficulty is too tall, say submarine hangs down so standing is special not actual, also do not make even the modernest submarine, be submarine of World War II what is more,the rather that more?
The cabin of each ballast water of submarine and operate the position of helm face, through them submarine ability realizes ups and downs and control of Shui Zhongzi state.
Again to say the least, in calculating submarine to be able to accomplish water, hang down stand, face the difficulty that torpedo launchs even. Torpedo tube of period of World War II is relied on compress air to blast off, the gravitational action that below verticality emissive torpedo needs to overcome torpedo oneself and tremendous hydraulic, whether blast off go out very suspectable, even if can launch torpedo, whether hit the target the target is very debatable also. What period of World War II uses is the torpedo of straight boat type that does not have ability of control and guide mostly, need calculates speek of a ship or plane of target motion course carefully, the program shoots Zhu Yuan, undertake in use periscope visual it is very complex when fire with difficulty, and cannot see an end at all in underwater submarine, and support sonar locates also very not accurate, the submarine that mentions before Jiashangzhi is in hang down establish condition to fall to adjust attitude hard, so condition of very inaccessible fire. If you must realize perpendicular emissive torpedo, that not as perpendicular as direct installation still torpedo tube comes easily.
Submarine relies on sonar completely to feel circumjacent posture in underwater voyage, torpedo difficulty is shot in underwater blind very big.
