Siheyuan: I eat melons while doing scientific research

Chapter 1228 What is a car? There is also a motorcycle (5k)

"But Comrade Zhendong, the 270mm firepower is still a little lacking in precision strikes. Can you..."

Gao Zhendong laughed. Sure enough, it never ended.

"In this regard, if you need precise strikes, you should call on the Air Force's precision-guided weapons. After all, they are specialized in this..."

Although there were still some regrets and inconveniences, considering that with the support of the current tactical data link, the call speed was still acceptable as long as there were air force planes in the sky, the comrades from the Land Equipment Bureau nodded in approval.

"And..." Gao Zhendong made this turn of events just as they nodded.

Come on, come on, I like your twist the most. The comrades from the Land Construction Bureau have been dealing with Gao Zhendong for a long time. "And what?"

"Moreover, the other type of UAV that these comrades are going to develop can provide you with a certain level of real-time precision air strike capability on the battlefield." Gao Zhendong pointed to the comrades at the Qianfei Factory.

The comrade from the Land Construction Bureau grabbed Chief Engineer Jian's hand and said, "Great, great. What is it?"

Chief Engineer Jian was confused. What is it? I don't know what it is. What is Chief Engineer Gao talking about? I don't know now.

"Comrade, I don't know about this either. I haven't received the task yet. I have to ask Chief Engineer Gao."

Chief Engineer Jian’s answer left the comrades from the Land Equipment Bureau dumbfounded. There was nothing they could do, they really didn’t know.

They had no choice but to turn around again. Well, they had to come here to solve the problem. "Comrade Zhendong, what do you mean?"

Gao Zhendong smiled and said, "Cruise missile."

The comrade from the Land Equipment Bureau seemed to have remembered something: "I remember that the Air Force was planning to use the wreckage of the Firebee drone to make anti-radiation cruise missiles, right? Is this it?"

Gao Zhendong shook his head: "No, the Firebee is too big and has a long range for you. It is not suitable. What you need is a small drone with a remote control distance of tens of kilometers and a range of hundreds of kilometers, not something as big as the Firebee."

"How many hundreds of kilometers?"

"Yes, this thing will fly to the battlefield and cruise over it. When it finds a valuable target, it will control it to dive down. The plane doesn't need to be too heavy, 200 kilograms is the maximum, and the warhead doesn't need to be too big, 50 kilograms is enough. It can also be effective against general fire points and targets that are not too hard. With a range of hundreds of kilometers and a speed of about 100 to 200 kilometers, it can float over the battlefield for 2 to 4 hours. Is that enough for you to fight a battle?"

Enlarge the "Harpy" a little bit, the 32kg warhead of the "Harpy" is not good enough! Gao Zhendong himself actually has the same problem as Lu Jun.

The comrades from the Land Equipment Bureau and Qianfei Factory racked their brains and finally figured out Gao Zhendong's intention. It was not that they were stupid, but that they had never thought of this method before.

The comrade from the Land Equipment Bureau suddenly realized: "Ah, what you are talking about is a bit like the Japanese's 'Sakura' planes in the past, except there is no one on board. They fly over the battlefield like eagles, and only dive down when they find their prey! Well, this is good! It is more accurate than artillery shells, and the reaction speed is faster."

The Japanese's "Kaiten" torpedoes and "Sakura" suicide bombs are quite abstract. The torpedoes operated by the people of Leather Shoes Country at least have magnetic warheads, which can allow the operator to leave after attaching to the target, while these Japanese weapons are directly welded shut. The people of Leather Shoes Country have some achievements in using torpedoes, but the Japanese's Kaiten have almost none.

But in fact, the usage of "Sakura" is not quite the same as that of a patrol drone. This thing is actually equipped with a set of missiles that the Japanese use as wet parts. There is no patrol process, and the engine working time of this thing cannot support the patrol operation at all.

However, Gao Zhendong did not dwell on this and said with a smile: "Yes, it is just like an eagle on the prairie, flying over the battlefield and attacking when it finds the target."

"But this thing is disposable and should not be too expensive. The optical system cannot be improved, and it cannot be equipped with a thermal imager. Will the search efficiency be affected?" The comrades from the Land Equipment Bureau immediately became excited and began to think about deeper things.

Gao Zhendong said, "This is easy. Let our infantry comrades carry special colored smoke bombs, such as green or purple. Throw one at the target that needs to be hit, or even use a grenade mounted on a gun to hit it. Watch for smoke during the day and fire at night. This can more or less solve some problems. This cruise missile is cost-effective, but we can still equip it with a set of color cameras. We can't be so stingy with this little money."

In my previous life, I was very familiar with COD (Call of Duty series), Gao Zhendong thought.

The comrade from the Land Equipment Bureau slapped his head and said, "Hey, this is a good idea! It can directly solve the problem of accurate accompanying firepower during the assault, and as long as the front and rear communication is smooth, the reaction speed is very fast. Even if the front and rear communication is not smooth, the patrol drone operator can solve the problem as long as he sees the special color! Moreover, the 50-kilogram warhead can solve many problems that infantry portable assault firepower cannot solve."

The most powerful portable assault firepower for infantry is the Chijian-61, but the warhead is only a few kilograms. Mortars with greater range and power are inconvenient to carry, slow to react, and not very accurate. This cruise missile with a 50-kilogram warhead can solve many problems.

It has to be someone like Comrade Zhendong who has been on the battlefield. Not only does his ideas fit the needs, but he can also always come up with solutions! No matter whether these solutions are tacky or not, just tell me whether they can solve the problem!
For those of us who are used to infiltration, we don’t need too many. Sometimes, just one or two 50kg bombs can solve big problems in the process of light penetration!

Seeing that the comrades from the Land Equipment Bureau agreed with Gao Zhendong's idea, Chief Engineer Jian began to consider the problem from the technical details: "A 200-kilogram patrol drone is easy to deal with. It can be reduced in size according to the plan for battlefield surveillance drones."

Gao Zhendong shook his head: "This cannot use folding straight wings. The number of these is larger than that of battlefield surveillance drones, and their application must be universal. They cannot be too complicated. Moreover, they are disposable, so they cannot be complicated either. Besides, the engine of this thing is not big, and the drag of the straight wings is too great, and the speed will drop to an unacceptable level."

"What's the plan then?"

"A tailless delta wing! This thing doesn't need high maneuverability, as long as it can fly steadily and reach the target. This solution is the simplest. As long as the delta wing has enough area, the lift characteristics are not too bad, it can hold a lot of fuel, and it can also take into account speed. If you can do it, you can even save the vertical tail and use the ailerons on the delta wing to control the heading. If you can't do it, you can add one or a pair of folding vertical tails."

"Folding vertical tail? The control line will be difficult to handle whether it is hydraulic or steel cable." Chief Engineer Jian is quite knowledgeable about airplanes, after all, he is a professional in this field.

"Don't just think about the method for airplanes. You can think of this thing as an alternative missile, and you can also use the idea of ​​missiles to solve the problem. Use wires and a motor in the folding tail to deflect the tail. If the power is not enough, use a cycloidal pinwheel transmission to amplify the torque. This thing is small in size and can be placed in the folding tail without any problem. And the price is not high." Gao Zhendong's methods are many.

At this point, the comrades from the Land Equipment Bureau only need to listen.

After Gao Zhendong's explanation, the comrades of Qianfei Factory digested his entire plan and felt that it was very good, very mature, and almost ready-made. They were determined to remove the tail wing as much as possible. If it couldn't be removed, the plan provided by Chief Engineer Gao was also very useful.

It has to be a top expert like Chief Engineer Gao, who can provide you with the entire solution and even the technical details while discussing.

However, in the end, all of this can't get around one thing: "Where does the power come from? The 463 engine you just mentioned is too heavy, and the 363 engine should not work either."

Gao Zhendong seemed to have remembered something funny, and the smile on his face became more obvious: "Isn't there Shuangqing City in Shu Province next to our Qianshan? They should be producing motorcycles there..."

"Poof!!!!" Because it was difficult to get involved in the discussion of technical details, a comrade from the Land Equipment Bureau who was drinking tea nearby spat out a mouthful of water.

When Comrade Zhendong was making do with it, it was really make do... Not only the car engine, but also the motorcycle engine.

Chief Engineer Jian was also shocked by Gao Zhendong: "The engine of a 750 motorcycle?"

"Yes! This is almost enough, and its size, weight, and fuel consumption are all relatively friendly. Shuangqing is close to you, so it is more convenient to ask them for technical support." Gao Zhendong smiled. He had seen a lot of flying motorcycles in his previous life, and his two nephews used them very well in battle.

"We have 750 in our company..." Chief Engineer Jian lowered his head and began to calculate on paper.

After calculating for a while, he looked up and said, "Chief Engineer Gao, the engine power of the 750 is only 17.4kw. It seems that it is not enough to propel a 200kg aircraft according to your plan and achieve the flight performance you just mentioned."

Now that the plans have been finalized, Chief Engineer Jian can make some rough estimates. After all, the Gauls' delta-wing technology is not in vain. Gao Zhendong asked, "What is the biggest difference between the 750 motorcycle and this patrol drone?"

"The difference? One runs on the ground, and the other flies in the sky!" This question is simply an easy one!
Gao Zhendong shook his head: "No, one is to be used repeatedly for a long time, and the other is a one-time deal!"

A one-time deal? Chief Engineer Jian seemed to have remembered something. Look at his brain! He can't think flexibly at all, and can't grasp the essence and come up with a solution! It has to be Chief Engineer Gao.

"You mean, if it's a one-time deal, we can ignore durability and squeeze the performance of this motorcycle engine to the limit to increase its output power?"

Chicken blood engine is a very common engine modification method. It was very popular in the era of gasoline vehicles. Flashing the ECU can increase the horsepower by a certain amount. If you don’t consider the lifespan, you can squeeze out even more.

Gao Zhendong nodded and smiled, "That's what I mean. We'll only use this for a few hours, so we can be more aggressive when calibrating the operating parameters."

After that, he added: "As for the launch method, just like battlefield surveillance drones, rocket-assisted launch will do. You can load many drones in the back of a truck and store them in many compartments. In this way, when using them, you can open the compartment door to launch them. The front of the truck is the control station, and the truck is a firepower unit. It is very convenient to use."

Speaking of this, the comrades from the Land Equipment Bureau had something to say: "This is good, but why not use a universal tracked chassis?"

Gao Zhendong shook his head. "Crawler chassis are expensive! They are generally not used in the front lines, so they don't require off-road capability. They are also relatively light, so there are no requirements for the load capacity of the vehicle. At most, we can install fewer vehicles. All in all, trucks are the most suitable."

Oh, I forgot, when Comrade Gao Zhendong is stingy, he is really stingy!
He turned to his army comrades and said, "In this case, the price of this patrol drone will not be much higher than that of a 750 motorcycle. At least the difference will not be an order of magnitude. It is still relatively affordable for our troops to use it."

The most expensive parts of this thing are actually the image transmission and remote control systems. But since the Air Force can afford TV-guided bombs, it's not a big deal for the Army to use this thing, too.

The comrades in the army were all smiling. What a great thing! Several patrol drones that can stay on standby over the battlefield for 2 to 4 hours with high accuracy and be available on call, and with a 50kg warhead, can solve big problems.

"That's great. We will assign them to the regiment! If a regiment has three vehicles, it can solve a lot of problems!" The comrades from the Land Equipment Bureau even began to imagine the future and were already considering the issue of organization and assignment.

The comrades from Qianfei Factory remained silent and just took notes desperately.
-
The Gulf of Oil, the Red Sea, the Pharaoh Kingdom.

At a shooting range in the desert, two tank trailers stopped with a cloud of dust.

A Pharaoh officer jumped out of the first car and said to the group of people waiting here with a smile: "I have dragged the scrapped tank here. My Oriental friend, I am very curious about what you want to show us?"

The group of people waiting are our comrades, and next to them is a fully armed ZBD-63 infantry fighting vehicle. There is no other way. With the equipment blowout from 61 to 63, a large number of equipment named after these years have emerged in our equipment sequence. Without the prefix, it is really hard to tell which is which.

This ZBD-63 is the infantry fighting vehicle that was officially finalized last year and began to be equipped. This thing is mainly a novel concept. As for the technology, there is nothing to keep secret. It does not have composite and explosive reactive weapons, nor does it have thermal imagers or anything like that. It can be sold freely!

It was finalized one year earlier than the Russian BMP-1 and is truly the world's first infantry fighting vehicle.

The excellent design and novel combat methods attracted the Pharaohs who came to us to purchase equipment at that time, and they bought a batch of them. After taking back the canal, they had a lot more money.

This ZBD-63 was borrowed from them temporarily.

One of our leading comrades stepped forward and said, "Don't worry, my friends. Come on, put the tank on the target. I'm sure you will be satisfied."

Although tanks are high-value land warfare equipment, the Pharaoh Empire, which has fought several Gulf Wars, naturally has no shortage of scrapped tanks, both its own and the enemy's.

And this time, we specifically asked them to get the enemy's tanks.

The Pharaoh officers were not stupid. Looking at the ZBD-63 behind their comrades, they thought: "My friend, do you want to use your infantry fighting vehicles to fight tanks? Your Chijian-61 anti-tank missiles are excellent. You don't need to prove this to us again."

Our comrade laughed and said: "No, my friend, it's not the Red Sword-61, but this 25mm gun. It's not a confrontation, it's just to show you a possibility."

The Pharaoh's military officer opened his eyes wide and expressed his surprise.

The ideas of our Eastern friends are a bit exaggerated.

Although the infantry fighting vehicle is new, its main weapon, in addition to anti-tank missiles, is the 25mm gun.

The Chijian-61 is an excellent missile, but it does not have the ability to fire and forget. It can only play a restraining role in a battlefield where things change rapidly and self-protection is needed at all times.

The 25mm gun does have a bit of a fire-and-forget attitude to it, after all, there's nothing you can do even if you want to. However, it is a barreled weapon that fires directly, so as long as you aim well, the hit rate is pretty good. The problem is that it can't penetrate a tank, not even the side armor.

Otherwise, in S2, the caliber of tank guns would not have soared from machine guns to 37mm.

At this time, the main tanks of Pharaoh's opponents were M-48, Centurion, M50, and M51. Although the numbers of the latter two tanks are larger than M-48, they are actually improved versions of M4 Sherman. Pharaoh's opponents modified them themselves, and there is no such number in the country of origin, Citigroup.

A very incredible fact is that the main tanks between the 1950s and 60s generally had thicker armor than the Hans' Leopard 1 and the Gauls' AMX-30. These two tanks are truly fragile, thinner than the M-60. If it weren't for this, they wouldn't have been so scared of the Russians' armored torrent at the time, because their tanks were generally weak.

Even the M50 and M51, two old but new models, are at the same level as these two or even better in terms of armor thickness.

Our comrade smiled and said, “You’ll know after you give it a try.”

While they were chatting and laughing, the people who were setting up tank targets a few hundred meters away were also busy. Soon a report that preparations were complete came over the radio.

In addition to placing the tank on the target, they also placed some fuel inside the tank.

"I look forward to your performance, our Eastern friends." The Pharaoh officer said with a smile.

Our comrade turned to the open turret hatch of the ZBD-63 and shouted: "Prepare to fire!"

A minute later, with a burst of "boom boom boom" sound, sparks flew from the first tank in the distance. It's no wonder that the ballistic performance of this 25 gun is very good, with small dispersion and a high hit rate in static-to-static shooting.

Soon, thick smoke began to billow from the first tank.

"How is it, my friend?" our comrade said to the Pharaoh's officer.

"My friend, how did you do it? Even the side armor." The Pharaoh officer opened his mouth wide.

On the opposite side is an M4. Although its gun is different from the M50/51, its armor is similar. However, there are many models of M4, and the specific armor thickness varies.

But the Pharaoh officers knew that the M4 on fire on the opposite side was the armor-reinforced M4A3E2 model. Under normal circumstances, its side armor could only be penetrated by a 76mm artillery at a distance of about 300 meters!
