Chapter 2871: French gift of sword three

First of all, you want to put down as many as 80 fighters, which requires a fairly large hangar! How big is this hangar? Even considering the plane's folding wings, French engineers said that the size of the hangar must be at least 190 meters long and 25 meters wide! And this width is still the net size, does not include the elevators before and after the aircraft carrier hangar! If according to the previous plan, two lifts with a length of 13 meters are added to the front and the rear, then the total length of the hangar is 213 meters, and I want to get it on a battleship with a maximum length of 230 meters. With such a long hangar, I can only say, are you funny?

The size of a warship alone is enough to limit this hangar, not to mention that a single-layer hangar covering such a large area requires multiple horizontal armors and the structural weight to support this armor. Therefore, in the first time, The French can only abandon the setting of a single-layer hangar.

Well, now the question is, if a double-layer hangar is set up on a 230-meter-long aircraft carrier, how long should this hangar be? After referring to the relationship between the length of the double-layer hangar of some German aircraft carriers and the hull, the French concluded that if the elevator space is not calculated, it is more appropriate for the hangar to reach about 60% of the length of the aircraft carrier. In other words, the net length of the hangar should be about 140 meters.

So, in the end, the French set a net length of 135 meters for the aircraft carrier's hangar, and a width of 19 meters. Considering that the Japanese required the warship to have as much ammunition and aviation fuel reserves as possible, the French finally designed a one-and-a-half-story hangar for the aircraft carrier, which means that the length of the lower hangar should be smaller, only 90 meters up and down. The remaining space is used to accommodate other compartments. However, after this adjustment, the aviation fuel load of this aircraft carrier reached 700 tons.

After the hangar is designed, it is the layout of the elevator. The French also encountered the problems of elevator layout and double-layer hangars between the United States and Germany, and France solved it in this way. They placed a total of 3 elevators on the aircraft carrier, two of which were side-string elevators to communicate with the upper deck. The hangar and the deck, and the other lift is an in-string lift, used to link the double-deck hangar and the upper deck. According to the French design, the lower hangar is used to maintain aircraft and store spare aircraft and parts most of the time. Under normal circumstances, the aircraft ready for combat are on the deck and in the upper hangar.

After completing the design of the hangar and elevator, it is the flight deck. According to the current attack intensity of carrier-based aircraft, the French believe that the horizontal armor of 60MM is sufficient to withstand bomb attacks from all single-engine attack aircraft, and 60MM is not completely. It is the armor plate, but the uniform steel armor of 40MM and the structural steel back plate of 20MM, plus a total of 60MM. This armor plate covers an area of ​​135 meters long and 19 meters wide. Although the aircraft carrier designed by the British for Japan also considered the armored deck, the area is only 110 meters long and 14 meters wide. Obviously a lot smaller.

In order to support such an armor plate, the French also thought about the design of the hull. First of all, it is impossible for the two-story hangar to be completely open. After all, the floor of the lower hangar is almost close to sea level. Therefore, the lower hangar of the French is a closed structure, which means that this hangar is integrated with the hull structure. The upper hangar has also become a closed hangar at the front and an open hangar at the rear. The structural strength of the closed hangar can naturally support the upper armored deck. The open hangar at the rear can also open the side walls and let in air to warm up the machine.

From a purely design point of view, the French have done a very good job. The first and a half hangars have solved the problem of aircraft capacity. It also reduces the area of ​​the armored flight deck. A decent defense was obtained with a lower weight cost. The semi-open hangar used in the upper hangar also solves the conflict between the support structure and the warm-up.

But are there any flaws in the French design? This is naturally possible. First of all, due to the hull restrictions, the height of the two hangars is not too high. The upper hangar is about 4.5 meters in height and the lower hangar is 4.2 meters. There is no problem with the current aircraft, but in the future It depends on the situation.

Another flaw is that the French aircraft carrier designed for Japan only has one layer of horizontal armor! The horizontal defense of the upper part of the warship hangar is only 60MM, and there is no one inch of armor steel from the hangar deck to the lower part! And only a layer of structural steel and the armor belt of the side strings form a weak upper armor box.

But no matter what, the French aircraft carrier design can be considered as a leap forward. They designed at least the first batch of armored aircraft carriers! The experience of the Japanese during the war also gave this warship a great improvement in soft power ~www.wuxiaspot.com~ For example, the Japanese had already undergone actual combat inspections in the war. The empty tank-liquid tank-empty water tank Under the defense system. For example, the Japanese improved ammunition delivery system and the protection of aviation fuel tanks. It can be said that this class of aircraft carrier is a very advanced new generation aircraft carrier.

So far, the No. 7 plan is still going smoothly. The warship has been launched a few months ago and is now being quickly outfitted. Thanks to the fact that the French installed a new small water tube boiler on the warship and from Germany With the imported Bremen steam turbine, this warship can reach a speed of more than 26 knots or even 27 knots!

If it continues at the current rate, it is estimated that at most one year, this aircraft carrier can complete its service. Of course, considering that the French have not studied the issue of carrier-based aircraft, and that it is impossible for the Germans to sell carrier-based aircraft, this aircraft carrier will still use British carrier-based aircraft. This secret will be revealed sooner or later, so Hayao Shimamura told Betty at least half the truth.

Although the French and Japanese have cooperated in aircraft carrier design, the real cooperation is still the army, and now, the long sword from faraway France will soon appear in the land battle of New Guinea!
