1/200 Japanese Type 93 Torpedo Long lance Upgrade Set Detail Up Set CYG048

Description: 6 pcs of torpedoes pack in a set. It been designed to adapt with 1/200 warship, length in 4.5 cm. Main body is made in Aluminium, under restrictive CNC production. Modeler utilizes the brass photo etches to assembly its fins and supporting/ transport frame. Frame is provided two versions in small/ large scroll wheels. The Type 93's development (in parallel with a submarine-launched model, the Type 95) began in Japan in 1928, under the auspices of Rear Admiral Kaneji Kishimoto and Captain Toshihide Asakuma. The torpedo design was inspired by the British oxygen-enriched torpedoes used on the Nelson-class battleships. At the time, the most powerful potential enemy of the Japanese Navy was the United States Navy's Pacific Fleet. The Japanese Navy invested heavily in developing a large, heavy, and long-range torpedo, the Type 93. Torpedoes were the only weapon that gave small warships, such as destroyers, the potential to cripple or sink battleships. The IJN's torpedo research and development focused on using highly compressed oxygen instead of compressed air as the fuel oxidizer in the torpedo's propulsion system. These torpedoes used an otherwise normal wet-heater engine burning a fuel such as methanol or ethanol. Since air is only 21% oxygen (and 78% nitrogen), pure oxygen provides five times as much oxidizer in the same tank volume, thereby increasing torpedo range. In addition, the absence of the inert nitrogen resulted in the emission of significantly less exhaust gas, comprising only carbon dioxide, which is significantly soluble in water, and water vapor, thus greatly reducing tell-tale bubble trails. Compressed oxygen is dangerous to handle and required lengthy research and development, not to mention additional training for the warship's torpedomen, for safe operational use. Eventually, the IJN's weapons development engineers found that by starting the torpedo's engine with compressed air, and then gradually switching to pure oxygen, they were able to overcome the problem of explosions that had hampered it before. To conceal the use of pure oxygen from the ship's crew and any potential enemy, the oxygen tank was named the secondary air tank. The pure oxygen torpedo was first deployed by the IJN in 1935. 酸素魚雷は熱走式で圧縮空気に替えて純酸素を使用したものである。これにより排気ガスの成分はほぼ炭酸ガスと水蒸気のみとなる。蒸気は言うに及ばず炭酸ガスも海水によく溶けるため、酸素魚雷は雷跡をほぼ引かないという、電気式に準じる隠密性が特徴である。また、通常の熱走式よりも燃焼効率が大きく向上したことで速力（雷速）・航続力もさらにパワーアップした。純酸素の使用で多くの利点が得られることは広く知られていたが、激しい燃焼反応のため機関始動時などに容易に爆発するという技術上の問題点が立ちふさがっていた。そうした中、日本は1933年（昭和8年）、世界に先駆け酸素魚雷の開発に成功。以降、大戦を通じて唯一の酸素魚雷運用国となった。実用化にこぎつけたのは日本以外ではイギリスのみであった。そのイギリスも、純酸素ではなく、酸素を増加した、空気魚雷と酸素魚雷の中間のようなものである。酸素魚雷は当時の他国魚雷の水準に比して、雷速と炸薬量で優り、射程は数倍、加えて航跡の視認が困難という高性能なもので、それによって戦争で連合軍の艦艇は多くの損害を被り、1943年に鹵獲されるまで連合軍は魚雷について知らなかった。一方で、酸素魚雷の整備性は良好とはいえず誤爆を防ぐために充分なメンテナンスを要し、また、速すぎる雷速の為、船底爆破用の磁気式の信管が使用できず、接触式信管を採用せざるをえないなどの短所もあった。後に日独技術交換により大日本帝国海軍からドイツ海軍へも試験供与されたが、戦略的位置付けの違いもあり、整備性の悪さなどからUボートでの使用には適さないと判断され、採用されていない。 For more 1/200 & 1/350 upgrade set, welcome to visit our online store on eBay via: https://www.ebay.com/str/hugohk/1-350-Ship-Detail-Up-Set/_i.html?_storecat=30800745018 https://www.ebay.com/str/hugohk/1-200-Ship-Detail-Up-Set/_i.html?_storecat=30800744018 Shipment：All of our small parcels strictly fulfilled eBay's mandatory shipment policy.
