The bombsight was also known as the Blackett sight after its primary inventor, P.M.S. Blackett. Production of a slightly modified version was also undertaken in the United States as the Sperry T-1, which was interchangeable with UK-built version. Developed in 1939, the Mk. XIV started replacing the World War I-era Course Setting Bomb Sight in 1942. The Mk. XIV was essentially an automated version of the Course Setting sight, using a mechanical computer to update the sights in real-time as conditions changed. The Mk. XIV required only 10 seconds of straight flight before the drop, and could account for shallow climbs and dives as well. More importantly, the Mk. XIV sighting unit was much smaller than the Course Setting sight, which allowed it to be mounted on a gyro stabilization platform. This kept the sight pointed at the target even as the bomber manoeuvred, dramatically increasing its accuracy and ease of sighting. The Mk. XIV was theoretically less accurate than the contemporary Norden bombsight, but was smaller, easier to use, much more quick-acting, and better suited for night bombing. It equipped the majority of the RAF's bomber fleet, with a small number of Stabilized Automatic Bomb Sights and Nordens being used in specialist roles. In spite of being much simpler than tachometric designs, or because of that, the Mark XIV remained in use long after the war, including use on the V Bomber fleet. ==History== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mark XIV bomb sight」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
