HMS ''Bellerophon'' was a central battery ironclad built for the Royal Navy in the mid-1860s. ==Design and description== In this ship, designed by Sir Edward Reed, the power-to-weight ratio was increased; the long rows of guns on the broadside were replaced by a small number of guns, centrally placed, of the largest possible calibre; the armour was increased in thickness but reduced in length, and a sharp beak ram was combined with a classical style plough bow. This double bottom had the added advantage of allowing the engine to be carried higher, raising the centre of gravity of the whole ship and making her thereby a steadier gun platform.〔Parkes, p. 103〕 Unlike earlier classes, ''Bellerophons bow and stern had a "U" shaped profile, giving increased buoyancy at the ends noticeably absent in some earlier battleships.〔 ''Bellerophon'' carried the first balanced rudder in Royal Navy service. Full helm could be applied by eight men in about 27 seconds,〔Parkes, p. 104〕 whereas in HMS ''Warrior'' it took forty men 90 seconds to perform the same manoevre.〔Parkes, p. 20〕 HMS ''Bellerophon'' was long between perpendiculars. She had a beam of and a maximum draught of .〔Ballard, p. 241〕 ===Propulsion=== ''Bellerophon'' had one 2-cylinder trunk steam engine made by John Penn and Sons driving a single propeller.〔Ballard, p. 246〕 Eight rectangular boilers provided steam to the engine at a working pressure of . The engine produced a total of n during the ship's sea trials in August 1864 and the ship had a maximum speed .〔Ballard, pp. 246–47〕 ''Bellerophon'' carried of coal, enough to steam at .〔Parkes, p. 102〕 The ironclad was ship rigged and had a sail area of . ''Bellerophon'' was "dull under canvas" and only made under sail in a moderate gale.〔Parkes, p. 106〕 The ship's propeller could be disconnected to reduce drag while under sail.〔Ballard, p. 67〕 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「HMS Bellerophon (1865)」の詳細全文を読む スポンサード リンク
