Ron first took out a pack of coconut sugar from the suitcase, and then he continued to take out other things like magic amidst the cheers of the two children, two little rabbits made of shells, two

Little dolls made of coconut shells, several strings of shell necklaces and Baker bracelets, and several conch horns made of large conches.

Both children opened their eyes wide and looked at the lot of good things. They didn't know which one to take. They touched this one and picked up that one. They were as happy as two happy birds.

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

"Mom, if you don't tell me, I don't think I'm really hungry."

In a short while, a large table of food was ready. It seemed that it had been prepared well in advance, and there were a lot of delicious food on the table.

Everyone - father, mother, elder brother, elder sister-in-law, and two little girls - all sat at the table. Ron picked up the knife and fork and was about to start. At this time, he heard his father cough slightly. He looked,

He found that except for himself, even the two little girls were sitting upright and not looking away. So, he smiled sheepishly and put down his knife and fork. Seeing Ron put down his knife and fork, his mother nodded slightly.

Nod and say: "Start."

All the people clasped their hands on their chests and chanted in a low voice together: "Our Father in Heaven, thank you for giving us..."

Ah, there is this, but there is very little relevant information in the remaining memory. It seems that the previous owner of the body may not care much about these rituals.

After praising God, dinner really begins. Ron’s family is still very traditional. During the meal, no one speaks, and you can’t hear the sound of knives and forks clashing with plates. In that era, this was very traditional for some families.

It is basic upbringing, and even the two little guys who have been doted on are no exception.

After the meal, everyone gathered together to chat again, and Ron's experience was of course the most concerning to everyone. He had to tell everyone his stories one by one, which attracted everyone's admiration. Old Sean, Ron's father, was even more so.

He proudly declared that none of his sons were good.

Ron also asked about his second brother's situation. Two months before the war started, Ron's second brother sent a letter to his family, saying that he was going to China to provide voluntary medical services, and left the United States. This

This was not the first time he had done something like this. A few years ago, he had gone to Spain once. According to himself, he was able to get to know Hemingway, who was working as a war correspondent at that time. But this time the situation was different.

It's very different. First of all, his letters to his family are much less than when he was in Spain. The most recent letter mentioned that he was preparing to go to more dangerous guerrilla warfare areas. After almost six months, his family never received any more letters.

received a letter from him.

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

Finally, the old man said: "It's already very late. Ron has been riding in the car all day and it's time to rest."

That night, Ron slept soundly and barely had a dream.

The next day was Sunday, so the eldest brother did not go to work. That morning, Ron found Henry and told him that after the battle, he felt that the firepower of the American fighter jets was not enough. So he randomly designed two

This is a machine gun, I want to let my professional brother know it.

"Ron, you still want to try everything as before. Do you still remember the oversized wheeled unicycle you designed when you were a child? That's why I have no front teeth." Henry laughed, showing the sparkling tooth in his mouth.

Shining gold teeth. "Let me see what kind of deceptive thing you devised when you were bored."

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

"Well, this is a Gatling cannon... Hmm? Is it an internal energy cannon? Well, this design will reduce the reliability... But if the craftsmanship can keep up, the reliability will not be unacceptable.

If this guy is really made, the firepower must be very abnormal... Well, Ron, which fighter can carry this thing? Is this thing probably weighing 150 kilograms? With such a high speed, the recoil is also amazing

Yes, can a fighter jet carry it? It can be used as self-defense firepower on a bomber, but it may be a bit inflexible when turning. Well, it might be good to use it as an anti-aircraft gun."

The first sketch Henry looked at was Ron's reduced-caliber version of the 23mm 6-barreled Gatling gun based on the Russian mig31. This gun can have a maximum fire speed of 10,000 rounds, and compared with its American counterpart, it uses

The internal energy method does not require a power supply system, and the weight of the entire system is much lighter. Of course, the reliability will also be reduced. In addition, the ballistic performance of the Soviet 23mm artillery shells is poor, and the accuracy will be lower than that of the American Vulcan.

The gun is slightly different. Compared with the original version, Ron reduced the caliber to 20mm, modified the firing device accordingly, and lowered the firing speed to 4000-6000 rounds. However, he did not reduce the size of the gun accordingly.

The length-to-diameter ratio of the gun barrel has become much larger. If Ron copied the 20mm shell from the American Vulcan 6-barreled Gatling cannon, based on Ron's own calculations, the muzzle velocity could reach over 1000 meters per second.

The ballistic performance will be better than that of the .50. Although it will definitely not reach the level of the Vulcan, it should be quite good. As for the question raised by Henry, Ron knew that the United States did not have one in active service at the time.

A fighter jet can carry this thing. Even if it can, this thing cannot be installed in the nose of any fighter jet. It is too big. But Ron knows that there is a fighter jet that is being tested that can use it.

.This kind of aircraft is the P-38 Lightning.

The p-38 "Lightning" fighter jet was a later arms juggernaut. It was the first military aircraft developed by the American Lockheed Company and was designed by the legendary Kelly Johnson. This is a twin-engine heavy-duty fighter jet.

The first American fighter jet with a speed exceeding 400 miles per hour (this is controversial, the Navy believes that its F4U Corsair is). It is fast, climbs well, has strong defense, and has a large bomb load. Due to the installation of a turbocharger system,

The high-altitude performance is also extremely outstanding. In the original history, this kind of aircraft was feared by the Japanese and called the Twin Devil. For the aerial cannon designed by Ron, this kind of aircraft has one of the biggest advantages: its

The engines and propellers are distributed on the left and right sides. The nose part is basically empty and can accommodate a lot of things. In the original history, the P-38's nose was equipped with 4 .50 machine guns and a 20mm cannon. These guys

It adds up to a full 170 kilograms. Now if it is replaced by a 6-tube Gatling, there will be no problem at all in terms of weight. And because this aircraft is large enough and has a strong structure, it can fully withstand its recoil.

Originally, the cannon Ron was most familiar with was the Russian-made double-barreled 23mm Sturga cannon. Before time travel, many of his company's products used this cannon. The biggest advantage of this cannon is its light weight.

High speed. The entire gun weighs no more than 50 kilograms, but it can reach an ultra-high speed of 3,000 rounds. However, the shortcomings of this aircraft gun are as obvious as its advantages: the trajectory is curved and the accuracy is extremely poor. It is very difficult for modern fighter jets.

Generally speaking, there are very few opportunities to use cannons, so for aircraft designers, the worse the precision is, the worse it is. As long as it can save weight, it is a good gun. But for the current aircraft with cannons as the main weapon

In this era, the shortcomings of the cannonballs flying all over the sky were really unacceptable. Fortunately, Gao Tianxiang, as an aircraft gun engineer, had the opportunity to see some other famous aircraft cannons in the world at that time. For example, through a certain country in South Asia

The Vulcan cannon and Mauser 27mm rotary cannon obtained by the F16, as well as the 30mm single-barrel rotary cannon used by the Russian Su-27 series aircraft and the 23mm Gatling used by the mig-31. For a long time,

He circles around these things every day, and he can almost draw these classic aircraft gun drawings with his eyes closed.

Just when Henry was questioning Ron's drawing of Gatling, old Sean also happened to wander over. The old man had been bored and uncomfortable since he retired. Now he happened to hear Henry's words, so he stepped forward and took his hand from his coat pocket.

He took out his glasses, slowly put them on the bridge of his nose and said, "What is that? Let me take a look."

"Dad, look, this is an aerial cannon designed by Ron. I have to say that the design is quite professional. But I'm afraid he forgot where such a big thing can be installed on a fighter jet. Let me tell you.

, it’s better to simply make it bigger, it would be great to use as an anti-aircraft gun." Henry said while handing the blueprint to the old man.

The old man sat down on the chair next to him, lowered his head and stared at the drawings, and took out a magnifying glass from his pocket. This scene reminded Ron of Doraemon. The old man looked at it silently.

For a long time, Ron who was waiting aside had an illusion. He also wanted to see a pair of buds and leaves suddenly sprouting from the old man's gray hair, and then the leaves grew longer and longer, and became more and more beautiful.

The more... (Narrator: The village chief is going crazy again)

It took a long time for the old man to raise his head again, with a smile on his face. The morning sun shone on his smiling face, making his smile look particularly bright.

"Haha, the United States really has a fighter jet that can be equipped with this thing. The performance of this fighter jet is far superior to any existing fighter jets. Unfortunately, it has encountered some problems and cannot be delivered to the troops yet."

"What kind of problem is it?" Ron actually asked knowingly. He knew that the P-38 was the first Army fighter that was fast enough to encounter air compression problems. The tail tremors caused by the high-speed flight caused the P-38 in the US military to

It could not participate in combat until February 1942. And what's more troublesome is that this kind of aircraft cannot be pulled up when the speed is slightly higher when diving. Oh my god, that means you can only watch it kiss the ground.

.

"Oh, this guy will have tail tremors when flying at high speed. This is no longer a problem, but the inability to pull up during a dive has not been solved. God, what a genius design this aircraft is, but it has become a

A fighter jet that cannot dive..." The old man felt very sorry.

"Dad, after diving, is it impossible to pull up after reaching a certain speed? Then can you install a dive flap on it, just like a dive bomber. When the speed is too high and it cannot be pulled up, open it to slow down." Luo

En once again plagiarized someone else's method.

"This can be regarded as a method, but it's a bit slow to slow down in vain... But at least this change can be used. It seems that I have to go to the company again." The old man stood up and continued, "I'll tell you.

Mom, I’m at the company, don’t wait for me for lunch.”

"It's Sunday today, and many people in the company are not here. We should wait until tomorrow - if it can be solved like this, well, my brother's design will be put to use for the first time in history. Well, tomorrow we will apply for a patent first, and then

Just sell it... Well, Dad, Ron has another design here."

This drawing shows a 20mm single-barreled aircraft cannon. The size is much smaller than the one just now, and it should be able to be mounted on the wing of a fighter jet. However, it seems to be no different from ordinary aircraft cannons.

?Well, there is something different here, oh, the barrel of this gun can rotate. This is a rotating-bore gun. This design can greatly increase the speed without compromising precision. In history, at the end of World War II,

Germany designed a rotating-bore aircraft gun with a speed of 1,000 minutes and a muzzle speed of 1,000 meters. However, the war ended before it could produce many. Later, the Mauser Company used this principle to design and manufacture a gun with a speed of 1,000 meters.

1,700-minute cannon with a muzzle velocity of up to 1,100 meters per second, used in European fighter jets such as the Tornado and Typhoon. This cannon is powerful and has very good accuracy, but for the propeller aircraft of World War II, its weight and recoil are both

It was too big. Later, the Russians also used this principle to design a 30mm rotary cannon, with a fire speed of 1600 points. And due to the use of a series of new materials, the weight was reduced to only 45 kilograms. That is, and

Compared with Mauser, the muzzle velocity is a bit lower, only 850 meters per second. And the reliability is also a bit worse. And the recoil of the 30-gun is too great. If two guns are installed on the wings of existing fighter jets, it is estimated that once the gun is fired,

The wing is about to break. Even if it continues, since World War II aircraft are much lighter than modern fighter jets, it is estimated that when they fire, the aircraft will shake and the shells will fly randomly. It will definitely not work if they are copied directly.

Due to the lack of those new materials, although Ron compressed the caliber of the gun to 20mm - in order to reduce the recoil - the weight of the entire gun still reached 50 kilograms. However, this weight is barely acceptable.she

The speed also dropped to 1,400 rounds, but the muzzle velocity was maintained at about 1,000 meters per second. This time, both the speed and range exceeded the .50 machine gun. As for the power, do you still need to ask? The muzzle velocity of 20mm is higher.

, how can the power of a faster aircraft gun be comparable to the .50. I am afraid that any existing fighter jet will immediately disintegrate in the air if it is hit by a shuttle.

When designing these aircraft guns, Ron deliberately emphasized high muzzle velocity because he knew that many people in the United States have a .50 complex. If they cannot surpass the .50 in its best aspects, many guys may still choose the .50.

Finally, Henry carefully put away the drawings. He looked at Ron with bright eyes and said: "Although these two designs still have some room for improvement, they are definitely good things. They are infinitely better than the unicycles you had back then."
