Ron took out a packet of coconut candy from his suitcase, and then pulled out other things like a trick to the cheers of the two children, two little rabbits made of shells, two dolls made of coconut shells, a few strings of shell necklaces and Baker bracelets, and a few snails made of large conchs.

Both children stared at the pile of good things with wide eyes, not knowing which one to take, touching this one and picking up that one. Happy as two happy birds.

"By the way, son, you haven't eaten yet, have you?" Mom stood up again, "I'll go get you something to eat." ”

"Mom, if you don't say it, I don't think I'm really hungry when I say that."

In a short time, a large table of food was ready. It seems that it has been prepared in advance, and there are a lot of delicious foods on the table.

Everyone—father, mother, eldest brother, sister-in-law, two little girls—sat down at the table, and Ron picked up his knife and fork and got ready to go. At this time, I heard my father cough softly. When he looked at it, he found that except for himself, even the two little girls were now sitting upright without squinting. So, he smiled embarrassedly and put down his knife and fork. Seeing Ron put down his knife and fork, his mother nodded slightly and said, "Let's start." ”

All of them clasped their hands to their chests and whispered together, "Our Father in Heaven, thank you for giving us ......"

Ah [a] [this read] novel xstxt,And this.,But there's very little information in the residual memory.。 It seems that the former owner of the body may not have cared much about these rituals either.

Praise God and the supper really begins. Ron's house is still very traditional, and when he eats, no one speaks, and he can't hear the sound of knives and forks clashing against plates. At that time, this was a basic upbringing for some families, even the two little ones who had been doted on all the time.

After the meal, everyone gathered together to chat, and Ron's experience was of course the most concerned by everyone. He had to tell his story to everyone one by one, which attracted everyone's admiration. Shaun Sr. - Ron's father proudly declared that none of his sons were not good.

Ron also asked about the second brother. Two months before the war began, Ron's second brother left the United States with a letter to his family saying that he was going to China to volunteer for medical care. This was not the first time he had done such a thing, as he had been to Spain a few years earlier, and on that occasion he had been able to meet Hemingway, who was working as a war correspondent at the time. This time, however, the situation is very different. First of all, he wrote far less to his family than he had in Spain, and the most recent one mentioned that he was preparing to go to more dangerous areas of guerrilla warfare. After that, almost half a year later, the family never heard from him again.

The mention of the second brother made the originally happy atmosphere suddenly heavy. Everyone is full of worries. Ron tried to enlighten them, but didn't know how to speak.

Finally, the old man said, "It's late, Ron has been in the car for a day, and it's time to rest." ”

That night, Ron slept soundly, barely dreaming.

The next day was Sunday, so the eldest brother didn't go to work. That morning, Ron approached Henry, who told him that he sensed that the firepower of the American fighters was a little lacking in the firepower of the American fighters in addition to the battle. So he randomly designed two cannons, wanting to let the eldest brother know the profession.

"Ron, you still want to try everything like you used to. Remember that unicycle with oversized wheels you designed as a kid? That's how I don't have my front teeth. Henry laughed, revealing the shiny gold tooth in his mouth. Let me see, you guys have a kind of trick when you're bored. ”

Henry smiled and opened a sketch that Ron had given him.

"Well, it's a Gatling cannon...... Well? Is it an internal cannon? Well, this design will reduce reliability. …… However, if the process can keep up, the reliability will not be unacceptable. If this guy really makes it, the firepower must be very perverted...... Well, Ron, what fighter can carry this thing? I'm afraid this thing weighs 150 kilograms, right? Plus the rate of fire is so high, and the recoil is amazing, can the fighter carry it? Put it on the bomber as self-defense firepower, and I am afraid that it will be a little inflexible when it turns. Well, maybe it's good to use it as an anti-aircraft gun. ”

The first sketch Henry looked at was a reduced caliber version of Ron's 31mm-6 barreled Gatling gun on the Russian MiG6. The rate of fire of this artillery can be as high as 10,000 rounds per minute, and compared with its American counterpart, because of the internal energy method, there is no need for a power supply system, and the weight of the entire system is much lighter. Of course, reliability will also be reduced. In addition, the Soviet 23mm artillery projectile has poor ballistic performance, and the accuracy will be somewhat worse than that of the American Vulcan aerial gun. Compared to the original, Ron lowered the caliber to 20mm and modified the firing mechanism accordingly, reducing the rate of fire to 4000-6000 rounds per minute. However, he did not reduce the size of the cannon accordingly, so that the length-to-diameter ratio of the barrel became much larger, and if a 20mm shell copied by Ron from the American Vulcan 6-barreled Gatling cannon, based on Ron's own calculations, the muzzle velocity could reach more than 1000 m/s. Ballistic performance will be better than .50. Although the accuracy certainly can't reach the level of Vulcan, it should be pretty good. As for Henry's question, Ron knew that there was really no active fighter in the United States at that time that could carry it. Even if it could be carried, it wouldn't fit into the nose of any fighter jet, it was too big. However, Ron knew that there was a fighter plane that was being test-flown and could use it. Such an aircraft is the P-38 Lightning.

The P-38 "Lightning" fighter, which was later the arms giant, the American Locke?? The first military aircraft developed by the company Side, developed by the legendary Kelly?? Johnson presided over the design. It was a twin-engined heavy fighter and the first U.S. fighter to reach speeds of over 400 mph (this is arguably, the Navy thinks its F4U Corsair is). It has a high speed, good climb, strong defense, a large bomb load, and excellent high-altitude performance thanks to the turbocharging system. In its original history, this type of aircraft was feared by the Japanese and called it the Twin Demon. For Ron's guns, this aircraft had one of the greatest advantages: its engines and propellers were distributed on the left and right sides, the nose section was basically empty, which could hold a lot of things, and in the original history, the P-38 had four .50 machine guns and a 20mm gun in the nose. These guys add up to a whopping 170 kilograms, and now it's a 6-tube Gatling that doesn't have any problems at all. And because the plane is large enough and structurally strong, it can fully withstand its recoil.

Originally, Ron's most familiar cannon was the Russian-made double-barreled 23mm Stega gun. Before the crossing, many of his company's products used this cannon. The biggest advantage of this gun is its low weight and high rate of fire. The weight of the entire gun did not exceed 50 kg, but it was capable of reaching an ultra-high rate of fire of 3000 rounds / min. It's just that the disadvantages of this aircraft gun are as obvious as the advantages: the trajectory is curved, and the accuracy is extremely bad. For modern fighters, there are very few opportunities to use cannons, so for aircraft designers, a bad accuracy is a little bad, as long as it can save weight, it is a good gun. However, in an era like the current era when aircraft artillery is the main weapon, the shortcomings of shells flying all over the sky are really unacceptable. Fortunately, Gao Tianxiang, who was an artillery engineer, had the opportunity to see some other famous aircraft guns in the world at that time. For example, the F16 Vulcan cannon and Mauser 27mm rifled gun obtained through a certain country in South Asia, as well as the 30mm single-barreled rifled gun used by the Russian Su-27 series aircraft and the 23mm Gatling used by the MiG-31. For a long time, he circled around these things every day, and he could almost draw the drawings of these classic aircraft guns with his eyes closed.

Just as Henry was questioning Ron's drawing of Gatling, Shaun Sr. happened to shake over. The old man has been bored since he retired. Now he heard Henry's words, so he stepped forward, took out his glasses from his jacket pocket, put them on the bridge of his nose slowly, and said, "What is that?" Show me too. ”

"Dad, look at it, this is a kind of aircraft cannon designed by Ron, and I have to say that the design is really a bit professional. However, he may have forgotten where such a big thing can fit on a fighter, and if I want to say, it is better to make it bigger, it would be good to use it as an anti-aircraft gun. Henry said as he handed the blueprint to the old man.

The old man sat down in a chair beside him, stared down at the drawings, and pulled out a magnifying glass from his pocket. This scene reminded Ron of a dream. The old man watched silently for a long time, so that Ron, who was waiting on the side, had an illusion, and he wanted to see a pair of young bud leaves suddenly emerge from the old man's gray hair, and then the leaves grew longer and longer, more and more...... (Narrator: The village chief is crazy again)

It took the old man a long time before he raised his head again, his face full of smiles, and the morning sun shone on his smiling face, making his smile look extraordinarily bright.

"Hehe, the United States really has a fighter jet that can be equipped with this thing. The performance of this fighter is far superior to that of any of the existing fighters, but unfortunately it has encountered a little problem and cannot be delivered to the troops for the time being. ”

"What kind of problem is it?" Ron was actually knowingly asking. He knew that the P-38 was the first army fighter to be fast enough to run into air compressibility problems. The tail tremor caused by high-speed flight prevented the P-38 in the U.S. Army from participating in combat until February 1942. And even more troublesome is that such an aircraft cannot be pulled up at a little higher speed when diving. Oh my God, that means you can only watch it kiss the earth.

"Oh, this guy has tail tremors when flying at high speeds, which is no longer a problem, but not being able to pull up when diving hasn't been fixed yet. Oh my God, what a genius design this kind of plane is, but it has become a fighter that cannot dive......" The old man was very sorry.

"Dad, after diving, can't you pull up when you reach a certain speed? Can you put a dive flap on it, like a dive bomber? When the speed is too high and you can't pull it up, turn it on and slow it down. Once again, Ron had plagiarized someone else's methods.

"It's a solution, but it's always a bit ...... to slow down in vain But at least with this change, it can be used. It looks like I'm going to go to the company again. The old man stood up and continued, "Tell your mother that I'm going to the company, and don't wait for me for lunch." ”

"Today, Sunday, a lot of people in the company are not there. Let's wait for tomorrow - if we can solve it this way, well, my brother's design will come in handy for the first time ever. Well, tomorrow we're going to apply for a patent and then we're going to sell it. …… Well, Dad, Ron has another design here. ”

This drawing depicts a 20mm single-barreled gun. It's much smaller than the one you just had and should fit on the wing of a fighter jet. But it doesn't look like a normal gun, right? Well, it's a little different here, oh, this chamber can be rotated. This is a rifled gun. This design allows for a significant increase in the rate of fire without compromising accuracy. In history, at the end of World War II, Germany designed a rifled aircraft gun with a rate of fire of 1000/min and a muzzle velocity of 1000/m. But it didn't take much to make the war before it ended. Later, Mauser Company used this principle to design and manufacture a gun with a rate of fire of up to 1700 per minute and an initial velocity of up to 1100 m/s, which was used for European fighters such as the Tornado and the Typhoon. This cannon is powerful and accurate, but it is too heavy and recoil for a propeller aircraft of World War II. Later, the Russians also used this principle to design a 30mm rifled gun, which also reached a rate of fire of 1600 per minute, and due to the use of a series of new materials, the weight was reduced to only 45 kg. Compared with Mauser, the muzzle velocity is a little lower, only 850 m/s. And the reliability is also a little worse. And the recoil of the 30 guns was also too great. If two were to be installed on the wings of the existing fighters, it was estimated that the wings would break as soon as the guns were fired. Even if it continues, because the planes of World War II are much lighter than modern fighters, it is estimated that as soon as the fire is fired, there will be a phenomenon of planes shaking and shells flying around.

Due to the lack of these new materials, although Ron compressed the caliber of the gun to 20mm - which was also to reduce recoil - the weight of the entire gun still reached 50 kg. But the weight is barely acceptable. The rate of fire has also dropped to 1,400 rounds per minute, but the muzzle velocity has also remained at about 1,000 m/s. This time, both the rate of fire and the range exceeded the .50 machine gun. As for the power, do you need to ask? The power of a 20mm gun with a higher muzzle velocity and a faster rate of fire is comparable to that of .50. I am afraid that any kind of fighter plane in existence will immediately disintegrate in the air if it is hit by a shuttle.

In designing these guns, Ron deliberately emphasized high muzzle velocity. Because he knows that a lot of people in the United States have a .50 complex, if not surpass it in the best of .50. A lot of guys might still choose .50.

Finally, Henry carefully put away the drawings. He looked at Ron with sparkling eyes and said, "Although these two designs still have some things to be improved, they are definitely good things." It's so much better than your wheelbarrow back then. Otherwise, you don't want to be a pilot either. Just do it with me. ”
