Editing Courageous-class aircraft carrier (section)

=== Propulsion ===
The ''Courageous''-class ships were the first large warships in the Royal Navy to have geared [[steam turbine]]s. Arranged in two engine rooms, each of the turbines drove one of the four [[propeller shaft]]s. ''Furious''{{'}}s propellers were {{convert|11|ft|6|in|m|1|abbr=on}} in diameter. The turbines were powered by 18 [[Yarrow Shipbuilders|Yarrow]] small-tube boilers equally divided among three boiler rooms. The turbines were designed to produce a total of {{convert|90000|shp|lk=on}} at a working pressure of {{convert|235|psi|kPa kg/cm2|0|abbr=on|lk=on}}.<ref>Roberts, pp. 71, 76</ref> No significant changes to the machinery were made during the conversion process to any of the three ships, but their increased displacement reduced their speed to approximately {{convert|30|kn|lk=in}}.<ref name=f5>Friedman, p. 95</ref>

''Furious''{{'}}s fuel capacity was increased by {{convert|700|LT|t}} during her reconstruction, which increased her range to {{convert|7480|nmi|lk=in}} at a speed of {{convert|10|kn}}.<ref name=f3 /> The maximum fuel capacity of ''Courageous'' and ''Glorious'' was increased during the conversion to {{convert|3800|LT|t}} of [[fuel oil]],<ref name=b83>Burt 2012, p. 283</ref> giving them an endurance of {{convert|6630|nmi|abbr=on}} at 10 kn.<ref name=f3>Friedman, p. 363</ref>
