"Where did you get this?" Su Mo, who had just returned to the Dalian Naval Base from Beijing, was pulled into the car by his former opponent, Ye Ming, who is now a friend, as soon as he entered the door, and then ran to an airfield at the Dalian Naval Base. Stopped in front of a huge hangar.

"What are you doing? I'm so busy in Beijing, I haven't eaten yet, so why don't you take me out into the wilderness if you don't pick me up? Su Mo couldn't help but complain.

"You don't want to eat when you see this thing. This thing was brought by Cheng Yuan, the nephew of General Cheng Biguang, but this kid didn't go to the navy, but went to the Air Force Equipment Department. We all say that he forgot his roots, why do you go to the Air Force if you don't do a good navy? As a result, I didn't expect this guy to help now, and got an airplane from the Shaanxi Aircraft Factory, I thought it was a little interesting, so I called you over. Without waiting for Su Mo to answer, Ye Ming directly pulled Su Mo into the hangar, and at this time, there were still a large number of people busy in the hangar, surrounding an aircraft about 11 meters long and with a wingspan of nearly 15 meters.

"If I'm not mistaken, isn't this a product of the Shaanxi Aircraft Factory's failed bid for the Air Force light bomber program? If I'm not mistaken, this plane should be called a Cheetah. Su Mo looked at it carefully, and finally remembered this thing, right?

"Looks like you're pretty well-informed. That's right, this guy is the product of Shaanxi Fei's failed bid. Because this guy has less internal oil, a relatively short range, and a relatively small magazine, only a semi-buried magazine, and can only hold a 500kg bomb, he was finally vetoed by the Air Force because of the factors of range and bomb load. However, the speed and maneuverability of the aircraft are still good. Ye Ming said with a smile.

"What the Air Force doesn't want, what do we want him to do? We also don't need front-line bombers, our bombers have higher requirements for range and bomb load than the Air Force. This little guy is not for us. Su Mo frowned and said with some dissatisfaction.

"It's definitely not suitable as a land-based aircraft, but if you can take off from an aircraft carrier. It will be of considerable help to the increase in the strike force of the aircraft carrier fleet. You see, in terms of floor space, the area of such a bomber is much smaller than that of 2 torpedo machines. But it's faster, and it's faster with the entire attack formation. can reduce the attack time. From the point of view of attack power. If you can take off with two torpedoes. Then our lightning strike ability will be greatly improved. Ye Ming said proudly.

Although twin-engine aircraft can take off and land longer distances, if you consider their larger bomb load, even if the number is smaller, it is beginning to be tolerable. Plus twin-engine bombers have more internal oil. (Compared with single-engine aircraft.) In 1942, Japan's torpedo engine was no more than 1,000 liters of oil. The light Mosquito bombers of the same period also had about 2300L of internal oil. If the oil inside is reduced appropriately, the weight can be further reduced. After all, the normal combat distance between aircraft carriers is generally between 300 and 400km, and there is no need for too large a range. At this time, it is undoubtedly a good choice to exchange fuel for bomb load or reduce dead weight.

"You see, this plane is almost designed for use on ships! The oil itself is not much, only about 1500L. And it is still a semi-buried magazine. The weight of this aircraft is low compared to twin-engine aircraft with large built-in magazines and internal oil. The empty weight is just over 5 tons. The output provided by the two engines is also very large, the power-to-weight ratio is not low, and the take-off distance may be comparable to that of a fully loaded single-engine torpedo machine. As for the question of where to put the torpedo, my idea is to hang it directly at the base of the wing and fire it at one side. Wing folding can also be done, and if you can replace it with a new air-cooled engine with more than 1,500 horsepower, I don't think it's a big problem. Ye Ming began to advertise his carrier-based twin-engine aircraft. …

"Actually, if it's just a torpedo, I think that with the increase in engine power, a single engine aircraft will be able to install two torpedoes in the future. How much is one torpedo? But up and down 900kg. That's only 2 tons of that. Huaxia and the Entente have already begun to discuss plans for the development of a new engine in the 2000 hp class. And there are catapults to solve the take-off problem, so it is still feasible to say that a single-engine aircraft with two torpedoes. Su Mo said tastelessly. It's not that he didn't think about getting on a twin-engine plane, but he definitely wouldn't get on a twin-engine plane just to bring a torpedo.

"You know what? The General Armament Department has already begun to develop guided weapons. At present, the progress is relatively smooth, and the first guided bomb will be able to enter the range for live-fire testing within the next year. Ordinary bombs and torpedoes may soon become obsolete like battleships. Su Mo said.

"You mean to have carrier-based twin-engine bombers carry guided weapons? I understand a little bit what you mean, in fact, you also agree to develop carrier-based twin-engine aircraft, but your vision is a little farther. Ye Ming said thoughtfully. It's a great idea, but it's hard to achieve it at the moment. Let's not talk about when the guided weapon will be built, after it is built, it will definitely be necessary to install some guidance equipment and operators. In this case, the volume of the aircraft will inevitably increase, and with it, the weight will increase. And if the bomb load is maintained, then the total weight of the aircraft is likely to exceed the maximum weight that an aircraft carrier can take off. While this prospect is tempting, there are too many uncertainties.

"Yes. It is indeed difficult to realize this idea. We've made recommendations, but it's up to the technical department to see if it works. Su Mo said. I didn't expect you to have a lot of ways, huh? Do you need my brother to help you? Ye Ming looked at Su Mo in some surprise. Then he said half-seriously and half-jokingly.

"No, if I can't. It is estimated that there are few people who can do it. Looking at Ye Ming, who was slightly surprised, Su Mo said quietly. I'd better leave these things to my brother-in-law and the General Armament Department.

And just when Su Mo and Ye Ming were judging the quality of this aircraft, Xu Jie was also thinking about the issue of twin-engine carrier-based aircraft on board and equipped with guided weapons, the advantages of which naturally needless to say, thinking about the scene of a team of carrier-based aircraft throwing a ton of bombs on the opponent's aircraft carrier, Xu Jie was excited. And compared to single-engine aircraft, twin-engine aircraft also do have a great advantage. If you simply talk about the bomb load, I'm afraid it will not be much more than the AD1 Sky Raider, but the heavy-duty pylon-bearing capacity of the twin-engine aircraft is much higher than that of the single-engine aircraft, the AD1 has three heavy-duty pylons, but the maximum is only 2000 pounds of standard load, which is almost impossible to carry high-power anti-ship missiles. According to Xu Jie's idea, the weight of the anti-ship missile warhead should not be less than 800kg. Even if the engine works for only a dozen seconds, the remaining weight of less than 100kg obviously cannot fit an engine and fuel.

The load-bearing capacity of the wing root pylons of twin-engine aircraft is much higher, referring to the weight of the Fritz X bomb mounted on the JU88 and DO217 up to 1570kg. Then the wing root pylons have a weight capacity of at least 3,500 pounds or more. Therefore, these guided weapons can only be carried by twin-engine aircraft, and even if the total bomb load of single-engine aircraft is not low, it is impossible to carry such bombs because of the strength of the pylons and fuselage structure.

In addition to pylons, another problem is the problem of the restrictions on the use of guided weapons by technology in this era, and theoretically, the fire control system on battleships requires almost no human interference. But it's hard to say whether such a complex system can fit into an aircraft, so from a conservative point of view, each aircraft needs to be equipped with a dedicated guided weapons operator. One person can only operate one bomb, if you want to fire two bombs at the same time, you need at least two people, plus a pilot, then you need 3 people, plus the need to accommodate the relevant observation equipment and mechanical computers, this weight and volume is certainly not small, a single aircraft can not accommodate at all. …

If you look at the historical data, the bomb load and fuel load of a medium bomber together are about 4 tons. And during the 2nd World War, a twin-engine aircraft would not weigh less than 5 tons even if it did not have a bomb magazine, and the weight of a single pilot. And if you add the magazine, the empty weight will increase to more than 6 tons. Then, if two rounds of ammunition weighing more than 2.5 tons are loaded with a total weight of more than 2.5 tons under the condition of appropriately weakening the range, the take-off weight of this aircraft should be about 11 tons. The length of the aircraft is about 12 meters, and the width of the wings is about 17 meters. This is still the result of not bulleting, plus some margin. And then the question arises, can an aircraft of this weight take off and land with a full load from an aircraft carrier? Can the hangar be large enough for such a big thing?

The answer is yes, not to mention the special case of the B25 taking off and landing from an aircraft carrier during the Doolittle air raid in history. By the end of World War II, the ejection weight of the new hydraulic catapult that the Americans planned to equip the USS Midway aircraft carrier also reached 28,000 pounds! This weight is already equivalent to 12.7 kilograms, and together with the deck wind provided by the aircraft carrier at high speed and the power of the aircraft itself, it can actually support the take-off of larger aircraft. And over time, once the R2800 engine, which can be called a pervert, is successfully developed, then even a smaller catapult can take off.

Of course, the volume and weight of the twin-engine aircraft are still somewhat larger than the weight of a 30,000-ton armored aircraft carrier. These aircraft have a width of about 10 meters even with the wings folded. The hangar of a first-class aircraft carrier could not even do it with two twin-engine aircraft side by side. Therefore, in history, the Americans specially designed the Midway aircraft carrier in order to carry twin-engine aircraft such as the F7F, and if Xu Jie wants to put these aircraft on board, then it is also necessary to design a large armored aircraft carrier of more than 40,000 tons. Of course, the aircraft carrier design plan is still in the process of being demonstrated, and the specific design work has not yet begun.
