The "Meiyun" class gunboats belong to the 80 (imaginary) horsepower warships formulated in the Fujian Shipbuilding Five-Year Plan, and according to the original idea, the 80-horsepower warships belong to the small by-products built by "idle workers in the shipyard". However www.biquge.info in the design process, in order to emphasize the strengthening of the function of the reconnaissance ship, the main engine was replaced with a 150 imaginary horsepower small composite steam engine newly developed by France, and upgraded it to a high-speed gunboat with 150 virtual horsepower (750 real horsepower). The hull is 51.8 meters long, 7.48 meters wide, 4.57 meters deep, and the draft is 3.39 meters. The appearance is similar to the "Caojiang" built by the Jiangnan Manufacturing Bureau.
The armament consisted of a powerful 120 mm French breech gun (changed to a 140 mm French breech gun in 1872) and four 75 mm Prussian breech guns (sampans). The main guns were mounted on the open deck before the flybridge in a mast change mode, and the remaining four 75 mm secondary guns were mounted on the open deck sides behind the chimney. In 1872, the ship was equipped with four Lin-Haqikes 40-mm single-barreled machine guns and two Lin-Gatling machine guns.
There are a total of eight ships of this class: "Meiyun", "Fuxing", "Jianxing", "Fusheng", "Jiansheng", "Zhenhai", "Jingyuan" and "Zhenwei", starting from "Fusheng" to accommodate 200 (imaginary) horsepower main engine, the hull size and displacement have been increased, and the maximum speed can reach 14 knots. As soon as this class of ships came out, they immediately became a sought-after commodity for the transfer of coastal defense in various provinces.
During the Sino-Japanese War, except for the "Meiyun" ship, which was still stationed in Beiyang, the remaining seven ships participated in the war. Among them, the three ships "Zhenhai", "Jingyuan" and "Zhenwei" in the Nanyang Naval Division system participated in the "Battle of Fengshan Island"; because they were defeated by the heavy guns of the Japanese ironclad ship "Longxiang" and other ships, "Zhenwei" was damaged, and "Jingyuan" and "Zhenhai" were sunk. The four ships "Fuxing", "Jianxing", "Fusheng", and "Jiansheng" in the shipyard and naval division system participated in the "Battle of Langqiao" and sank the Japanese ship "Meng Chun", thus contributing to the victory of the naval battle.
In order to give more emphasis to the function of the "high-speed reconnaissance ship," Lin Yizhe instructed the chief engineer of the shipyard, Da Shibo, to design a type of high-speed information ship on the basis of the "Meiyun" class, which is the origin of the "Feiting" class.
The line type of the "Feiting" high-speed notification ship has been carefully designed by the chief engineer of the ship, Da Shibo, and it has lengthened the length of the "Meiyun" class (the total length without the bow mast reaches 62.5 meters, and the "Meiyun" class is only 58 meters), and the width has been shortened (from 7.48 meters to 7.3 meters in the Meiyun class), which is more conducive to high-speed navigation; the power system configuration is very trendy, and the British 250 imaginary horsepower and 2000 real horsepower three-rise composite steam turbine (an improved model of the "Weiyuan" class main engine) are adopted. It is equipped with 4 car-mounted boilers. At that time, the three-rise composite steam turbine was also a novelty in Britain, and the British provided this kind of main engine to the shipmaster not only to counterbalance the influence of France in the shipyard, but also to use the Chinese warship as a "guinea pig" to test the new power system. (At that time, the performance of the automobile boiler and the French double-headed round high-pressure boiler was equally equal, so the shipmaster adopted an eclectic approach when building the "Feiting"-class high-speed notification ship -- the first ship "Feiting" and the second ship "Feiying" used automobile-type boilers, while the third ship "Feipeng" and the fourth ship "Feihong" used French-type circular high-pressure boilers) It is with such a luxurious power configuration that the "Feiting" becomes an out-and-out high-speed ship (of course, the warships of this class pay the price of living space). Because most of the internal space of the hull is occupied by engines, boilers and coal bunkers, the space of the main cabin of the crew and the living quarters of the officers is greatly compressed, and many crew members can only play hammocks in the open air, and can climb on the deck to breathe, which has also become a "welfare" that the sailors of this class of ships think about day and night), and the design speed can reach 18.5 knots. Also because the steam engine and boiler took up too much space, the ship was forced to sacrifice its armament, and was armed only with 2 75-mm Krupp breech-loading guns, 4 "Lin-Haqikes-Gatling" 5-barreled 40-mm machine guns, and 2 "Lin-Gatling" machine guns.
The four reconnaissance ships all participated in the Sino-Japanese Jiaxu War and performed eye-catchingly, among which the "Flying Thunder" ran at a top speed of 20 knots because of the holy decree of Fulin Yoshizhe; The "Feihong" participated in the First Battle of Langqiao and maneuvered with a whole Japanese fleet at high speed, covering the retreat of the sailing ships of the Penghu Naval Division, and finally successfully escaped. The three ships "Flying Thunder", "Flying Eagle" and "Flying Peng" took part in the "Battle of the East China Sea" and worked together to sink the Japanese gunboat "Yangchun". The "Flying Thunder" class high-speed notification ships played a very crucial role in the transmission of information throughout the war.
