之前我认为开放机库和封闭机库的区别，在于是否在机库外侧为强力结构，但有人指出这样说部队。. }( d0 c6 h$ ?

前几天有人说开放式机库和封闭式机库的区别就在于，机库侧壁外侧是否有舱室，如果机库外侧就是大海，则为开放式，如果外侧还有舱室，就是封闭式。

但又有人在我的一个帖子里面说过，如果机库在“船体”结构中，就是封闭式，如果在船体上，机库为上层结构的一部分，则是开放式。5 |: K- e; i& V* G D

In the Illustrious class, armour was carried at the flight deck level—which became the strength deck—and formed an armoured box-like hangar that was an integral part of the ship’s structure. However, to make this possible without increasing the displacement it was necessary to significantly reduce the size and headroom of the hangar. The later three vessels, Indomitable, Indefatigable and Implacable, had re-designed two-level hangars which enabled them to carry larger air groups than the original design. The size of the air wings was also increased by using outriggers and deck parks. The original design was for 36 aircraft, but eventually the vessels operated with a complement of up to 72 aircraft. However, the smaller overhead height of the hangars (16 ft (4.88 m) in the upper hangars and 14 ft (4.27 m) in the later ships with lower hangars) compared unfavourably to the 17 feet 3 inches (5.3 m) of the Essex class, 17 ft 6 inches (5.38 m) in Enterprise and 20 ft (6.10 m) in Saratoga. This restricted operations with larger aircraft designs, particularly post-war.

/ W, Z8 V8 T$ RThis armour scheme was designed to withstand 1,000 pound bombs (and heavier bombs which struck at an angle); in the Home and Mediterranean theatres it was likely that the carriers would operate within the range of shore-based aircraft. The flight deck had an armoured thickness of 3 inches, closed by 4.5-inch sides and bulkheads. There were 3-inch strakes on either side extending from the box sides to the top edge of the main side belt, which was of 4.5 inches. The main belt protected the machinery, petrol stowage, magazines and aerial weapon stores. The lifts were placed outside the hangar, at either end, with access through sliding armoured doors in the end bulkheads.

Later in the war it was found that bombs which penetrated and detonated inside the armoured hangar could cause structural deformation, as the latter was an integral part of the ship’s structure.

As the ship’s own firepower, rather than its aircraft, was relied upon for protection, the guns were mounted sufficiently high so that they could fire across the decks; de-fuelled aircraft would be stowed in the hangar for protection during aerial attack." x. i+ Y/ v1 e% v0 M& | [: |

大家如果提供说法，最好附上英文的说明，主要是国内资源少，所以还是看看外国资料的比较好。 |
