The technology that Donald said is more suitable for air combat is actually the machine gun shooting coordination device. ¦çObviously, in a high-speed air battle between aircraft, air-to-air rockets with such poor accuracy are very unreliable. This kind of thing is barely enough to fight against huge and slow airships, but it is not suitable for Attacking a much smaller, faster, and more flexible aircraft is like throwing stones at a dragonfly. Basically, it is useless. Therefore, the machine gun is the most suitable weapon in air combat. However, the machine gun at that time could only be mounted on the back seat and shoot to the sides and back. It was quite inconvenient to use. Some people thought that the machine gun should be fixed on the nose of the aircraft, facing forward. . This setting is not only convenient, but also saves the next occupant. It also makes the aircraft a lot lighter. The lighter the aircraft, the faster it will fly and the more flexible it will be. But this idea has a very difficult problem to solve, that is, there is a set of flying propellers in front of the nose of the aircraft. If you fire directly in front, the result will definitely be that your own machine gun bullets will smash your own propellers. , and then his plane fell from the sky. Based on the information MacDonald received, the French have already begun to study how to solve this problem. Of course, the French method is quite simple and crude. Their method is to armor the propeller so that bullets can't hit it. However, this deceptive design soon brought about another problem, that is, bullets hitting the propeller would be bounced around by armored bullets, or even bounce back directly. Then, either the pilot or the engine would die. A few days ago, the McDonald Infantry Weapons Company provided some technical assistance to the French, helping them design a more reasonable bulletproof propeller. This propeller can basically determine the rebound direction of the bullet at a fixed angle. In this way, the machine gun installed on the nose can barely be used. At that time, although this device made the forward-facing machine gun barely usable, compared with what Donald was now planning to sell to the Germans, the gap was quite obvious. Because the technology recommended by Donald now allows the machine gun bullet to be shot right through the gap of the propeller without damaging the propeller. In the original history, it was the Germans who invented this technology in mid-1915, and then later For a time, their Fokker fighters equipped with this device caused a Fokker disaster for the British and French. Now Macdonald has just brought this disaster forward a little. In Scrooge's plan, the British and French will first acquire a large number of attack aircraft using "air torpedoes", coupled with the French's barely usable fighter technology, these things will occupy the skies of the battlefield , and posed a serious threat to the German troops on the front line, and moved the balance towards the British. Then, they sold the technology of aircraft equipped with this device to the Germans, allowing them to fight British aircraft. It would be best if they could The British and French planes were swept away, and then they could make another deal with the British and French So, the world war was really wonderful. The Germans were indeed very interested in the technology that could allow bullets to pass through propellers, but Macdonald offered a very high price (it was said to be higher than the transfer fee for the entire aircraft plus the "air torpedo" combined) ), and insisted that they could only be allowed to see samples after paying a certain percentage of the deposit. Therefore, the Germans hesitated for a while and only purchased the related technology of the Sea Breeze fighter and the related technology of "air torpedoes". "After the French fighter jets start production, the Germans will negotiate this deal with us again. And by that time, they will not feel that our price is high." When Donald reported the German actions to Scrooge Scrooge replied. ¡°Don¡¯t the Germans have similar research?¡± Downer asked. "At least not yet. As for the future? Who knows." Scrooge smiled. Historically, Fockel and Heinrich Lubber, who played a key role in this invention, were already at Macdonald. Unfortunately, the watch expert Heinrich Lubber died in a traffic accident two years ago. "Donald, how are the Germans doing at sea now?" Scrooge asked. "After the German attack fleet was wiped out, Germany began to launch attacks with submarines. In the past two months, it has sunk many British ships. The British are now starting to use escort formations again, although the British have The number of escort ships is limited, and it is not possible to provide escort services for all merchant ships at the same time. Now, it is different from the time of attack ships. At that time, the British domestic inventory was still large, and the scale of the war was not as large as it is now. Of course. The consumption was not as high as it is now, so at that time, the British could still reduce the efficiency of the merchant ships and gather them together to wait for the escort warship to leave together. "Speaking of this, Downer said.De sneered. "But now, the situation is different. The consumption of the war is so great. Britain and France need a lot of supplies every day, much more supplies than before, so they can no longer tolerate a merchant ship waiting idle in the port for more than a week. In order to wait for the escorting warships. Therefore, the route is full of merchant ships traveling alone, which of course gives the Germans an opportunity, so their number of sinkings has been increasing. However, the British are accelerating the production of destroyers, and their production capacity is also considerable. , and they are also buying destroyers from us and other shipyards. Uncle, if we take all the orders given to us by the British, we can make a lot of money, but the good days of the Germans will probably come to an end soon. Because submarines have few options when facing an escorted fleet. In this way, as the number of escorting destroyers increases, the loss rate of merchant ships will decrease rapidly, which will directly reduce the damage to merchant ships. Total demand, this is not a good thing." Speaking of this, Donald frowned. "What's more damning, uncle, I think you may already know that the British and French have made a lot of progress in underwater listening devices. They are even imitating bats and dolphins to develop a A device that actively emits sound waves and then relies on echoes to locate it. You know, in principle, this kind of device is completely possible. "Yes, in fact, this kind of device has been successful in large laboratories. Scrooge said, "And it was installed on an experimental ship and successfully tracked a potential underwater submarine. Under the current situation, the British and French will definitely be willing to invest in this technology. In this way, I will." I think it won't be long before this kind of thing may appear on their warships. Well, Donald, do you think we should accept the contract to build destroyers for the British and French? " "Of course, uncle, because Even if we don't take it, others will. Instead of letting others make money, it's better to let us make it. Even uncle, I think the performance of the equipment in the big laboratory should be better than that of the British and the British. Is the one jointly developed by the French better?" Donald asked. "Our technical capabilities are not necessarily better than those of the British and French. But after all, we conduct research in this area first. Under normal circumstances, our products will naturally be better." Scrooge replied. "Then uncle, I think if the British and French are technically successful, we should sell this equipment to them immediately. However, this will reduce the demand for building merchant ships." When others have just achieved technological breakthroughs, When the situation arises, they immediately sell more mature and cost-effective products to others. This is also a trick used by the MacDonald Group. Because under such circumstances, most of the opponent's products will be difficult to compete with McDonald's products, so it will be difficult to recover large amounts of scientific research expenditures. At the same time, if any new technology wants to be perfected, it must accumulate a large amount of operating data and a large amount of improved data. If their opponents' products are not widely used, the accumulation of these things will naturally be slow, which will make them continue to lag behind McDonald's. In later generations, this kind of trick was also very common. For example, the White Eagle Gang has been imposing a technological blockade on the Red Rabbit Country. Whenever the Red Rabbit Country develops a technology that breaks through the blockade, the White Eagle Gang immediately approves the sale to the Red Rabbit Country of similar, but more advanced technology. It is a mature thing, and it is used to attack the relevant scientific research of the Red Rabbit Country. "Selling this thing to them is not a problem." Scrooge replied. "The problem now is that we must try to help the German submarine force to ensure that the balance is not easily upset. Donald, there is an important document here. , you go find Gray Stone, look at this document together, and then discuss how to provide the contents of this document to the Germans without anyone noticing. Note that it must not be allowed. Anyone, including the Germans, knows that these things are sent from us. It is best to make the Germans think that they came up with this good idea. " Scrooge said again, while opening the door in the office. A safe, took out a document from it, and said this to Donald. "This is it?" Donald asked doubtfully. "This is our latest research result. It is a brand-new submarine combat method that will change the history of naval warfare." Scrooge said to Donald with a smile while showing the name of the document to Donald. The name of the document that Donald saw was: "Wolf Pack Tactics."
