Design characteristics of autumn moon class destroyer

The main armed forces of the Qiuyue class are four 98-type 100 mm double anti-aircraft guns, the first two and the last two with backpacks. Due to the setting of the tall turret in front, the bridge of Qiuyueban was built very high. Behind the top of the bridge is the tripod of the anti-aircraft gun commander, and the open-air bridge above the compass bridge is the location of the air defense command post. Behind the chimney is the mechanism battery, equipped with two 96-type 25mm double guns, one on the left and one on the right. A 2-meter-high angle range finder is set in the center of the battery of the mechanism to indicate the target data for the 25-mm cannon. There is a 1 6 10 mm torpedo tube behind the mechanism battery, which can launch the famous type 93 oxygen torpedo. There is a reloading device in the left deck room behind the launch tube. In addition to carrying four torpedoes in the torpedo tube, four torpedoes are reserved in the reloading equipment.

Deep-water bomb devices are installed on the stern deck of the ship, including type III dropping platform and type 94 deep-water bomb thrower. The former has three on the left and right sides of the ship (two of them are released manually and four are released mechanically); The latter is arranged in the middle of the stern deck, one after the other. Total * * * can carry 54 depth charges. In addition, this class is equipped with 93 underwater sounder for finding underwater targets. Underwater sounder is equipped with many submarines and destroyers, but the actual use effect in war is not ideal. The main engine and boiler of the Qiuyue class used the same equipment as that of the Yang Yan class destroyer (at that time, the power equipment of the Yang Yan class was the most advanced in Japan), but the deceleration device of the main engine was completely designed. The boilers are three marine heavy oil-fired water-tube boilers, and the high-pressure steam pipes are all made of expensive copper materials to ensure the service quality of the boilers. Therefore, the boiler steam pressure reaches 30 kg/cm2, the steam temperature reaches 350 degrees (these two data are the highest values of practical boiler data of Japanese destroyers), and the unit fuel consumption is only 78.5% of that of special destroyers. Low fuel consumption ensures the requirements of this level of long battery life. According to Japanese data, at the speed of 18 knots, it can reach 8000 nautical miles in theory, but the measured results actually exceed the theoretical value and reach 9000 nautical miles at the speed of 18 knots.

There are two boiler rooms on this floor, two in front and one in the back. Compared with the mode of "one boiler room and one boiler", this arrangement saves hull space and reduces water displacement. The main engine of "Qiuyue" class is ship-borne steam turbine, including high, medium and low pressure steam turbines, which are driven by two shafts, with an output of 52,000 HP and a maximum speed of 33 knots. In order to reduce the damage caused by bullets, the main engine room is also divided into two parts. The front main engine room is equipped with port propulsion main engine and the rear main engine room is equipped with starboard propulsion main engine.
