Chapter 532 Report (first update)

"Leader, this is just an idea of ​​mine. The actual result cannot be determined. The error is likely to be hundreds of meters or even several kilometers away from the target." Liu Hai also knew that pure inertial guidance has great shortcomings.

The guidance system is divided into radio guidance, inertial guidance, laser guidance, infrared guidance, Gps guidance, and TV guidance.

In fact, every guidance system has major shortcomings. For example, a radio guidance system will paralyze the guidance system due to electronic interference.

In the earliest days, Sandoko used wireless electronic guidance, which was actually a remote control. At that time, dropping bombs from an airplane was a great test of the ability of the bomb thrower, because the bomb could reach a speed of 300 meters per second during flight. .

Even when attacking fixed targets on the ground, the hit rate often does not exceed 20% at most.

Laser guidance can be said to be very accurate. In order to bomb a large house during World War II, dozens or hundreds of bombs were often needed for carpet bombing.

Moreover, dozens or hundreds of bombs will have no effect if there is sudden weather such as gusts of wind.

However, laser guidance has one of the biggest shortcomings, which is that it is affected by weather, such as rain, snow, clouds and fog. This is why there are many machines in the army that specialize in firing smoke grenades, which can form a large smoke curtain wall over an entire area. .

Infrared guidance, this is the most commonly used guidance system in later generations, because it is not affected by rain, snow, day or night, and is not affected by electromagnetic interference, even if it loses contact with ground control.

TV guidance has a big shortcoming, that is, it cannot be used at night or when visibility is not high. It is good at other times. Later, TV guidance developed into terrain matching guidance for missiles, that is, during the flight of the missile , through the camera carried by the missile itself, it compares the reference object during flight. Once it reaches the target area, it will be compared with the picture of the building in the guidance system. Once it matches, it will attack.

Of course, the internal frame can be replaced with aluminum alloy.

To say it belongs to the aviation department? It feels inappropriate.

In fact, Liu Hai did not mention that radio positioning can also be installed to help the aerial scooter accurately locate, but Liu Hai does not plan to do this thing, because Liu Hai feels that as long as he builds the basic version himself and lets others do it later, he will be motivated.

So Sun Aiguo took the deputy director in charge of military affairs with him.

If the other party cannot make a contribution, then the motivation to do this will naturally decrease.

You have done everything perfectly, and there is no room for change when others get the project.

Because Sun Aiguo thinks that since it can fly 900 kilometers, if it is bigger, can it fly further?

As for what Liu Hai said is wrong, as a veteran, I am afraid of stray bullets. You have no idea where this thing is coming from.

Sun Aiguo got the drawings given by Liu Hai and felt a little troublesome when he got in the car, because who was in charge of this thing?

"Old Sun, what are you doing in such a hurry?" the deputy director in charge of military affairs asked after getting in the car and not knowing where he was going.

The cost of this kind of aerial motorcycle can be very low, and it can use a large number of composite materials, such as fiberglass, missile body and wings.

"The launch is just a slide, and then there is a solid rocket propeller underneath the bomb to send the bomb to a certain flight height. This is why the wings of this bomb are relatively large."

"I'll report right away." Sun Aiguo looked at Liu Hai, took the drawings to him, and ran away in a hurry without saying a word.

As for small motorcycles such as jet engines, it is not realistic to do this now, because before the guidance system has developed to high precision, the cost of making small motorcycles with jet engines is too high.

"Let's take a look at this first!" Sun Aiguo directly handed the drawing in his hand to the deputy director.

Moreover, glass fiber can be formed in one piece and directly made into various modules.

Of course, at this stage, it seems that the manufacturing cost of air scooters is still high, because first of all, the two-stroke opposed engine is relatively valuable.

It would be wrong to say that this belongs to the missile sequence.

Using a two-stroke opposed engine to propel it, even if it misses the target, the cost is not high, while the cost of a jet engine is too high.

But you want to say that it belongs to the military department alone? This doesn’t seem right either.

"It can be said that the farther the distance, the worse the accuracy." Liu Hai nodded. The farther the distance of the inertial guidance flight, the worse the accuracy.

"So how do you launch such a heavy thing? I'm afraid the engine can't push it? You don't see wheels or anything?" Sun Aiguo was now weighing the convenience and cost of this thing, so he asked.

The most accurate one is GPS guidance, but GPS relies heavily on satellite systems. If the two sides start a war, satellites will definitely be the first targets to be hit.

For current motorcycle manufacturers, there is no technical difficulty at all in manufacturing this kind of aerial motorcycle.

"It's just that the flying speed is a bit slow. This is actually what I was thinking about when I was designing the small single-person aircraft. Since the small single-person aircraft can carry a person to fly hundreds of kilometers, can I also install such an engine on a bomb? "

Sun Aiguo's car is now a Kyoto car. After turning on the lights in the back seat.

There is no global positioning system now, so there is only pure inertial guidance. If the accuracy is not good, there may be an error of several hundred meters. If something goes wrong, it may be off by a few kilometers.

"Can you tell me in detail?" Sun Aiguo was a little numb because he didn't understand what Liu Hai was talking about.

But compared with rockets and missiles, it has many advantages. The only disadvantage is that the explosive power is a bit weak.

"Of course it's no problem. I have a relatively detailed drawing here." Liu Hai said that the details were annotated.

"This is similar to a rocket, but it has a longer range than a rocket?" Sun Aiguo asked according to his own understanding.

"I designed this mainly to attack the opponent's logistics warehouse and large targets such as stations, and dozens, hundreds or even hundreds of bombs from long distances at the same time will always hit." Liu Hai further explained.

Moreover, this kind of aerial motorcycle has another advantage, that is, the various components made of composite materials can be made in advance, and the warhead and subsequent power equipment can be directly assembled when needed.

"Can I take this drawing of yours and report it to the superiors?" Sun Aiguo only has more than 100 kilograms in his mind, and a flight distance of more than 900 kilometers. As for the hit accuracy, it will fall at someone else's house anyway, let alone the flight speed. Yes, as long as I can fly there.

"I use a two-stroke opposed engine as power, and the speed is about 120 to 200 kilometers per hour."

Sun Aiguo nodded: "We can also attack airports, oil depots, and even their command organs. After all, they are such a long distance away."

The second-generation jet engine air scooter requires GPS and composite guidance to improve accuracy and hit valuable targets.

"I have been thinking about this project for a long time, and I think it is very promising. Even if the hit rate is relatively poor, as long as it can hit the opponent five or six hundred kilometers behind, they will be scared to death as long as they hear the sound of this bomb flying in the sky. It is very helpful to lower their morale." Liu Hai explained in detail.

"The entire design structure is relatively simple, consisting of a warhead, guidance system, control system, and power system." Liu Hai said as he took out the design drawing of the aerial scooter and introduced the structure of the entire aerial scooter in detail.

Besides, most of today's missiles also use inertial guidance. It's just that the missiles are very powerful.

Therefore, various subsequent guidance systems basically adopt different composite guidance systems according to their own use, that is, they are not a single guidance system.

The deputy director in charge of military affairs was still confused. In fact, the deputy director in charge of military affairs was not very involved in the specific management of the factory. He mainly supervised the military equipment produced in the factory, similar to the military representatives later.

The deputy director in charge of military affairs looked at the strange-looking thing on the drawing and thought it was an aircraft, but why was the propeller behind his butt?

Then I took a closer look and saw why this thing was so awkward. It had a warhead, inertial guidance, and a power system.

"This is a new idea of ​​Comrade Liu Hai." Sun Aiguo saw the deputy director's doubts and explained.

"This thing?" The deputy director in charge of military affairs was also a little confused. He was not proficient in this stuff either!

Because it involves aircraft, guidance systems, and warheads.

There is a gasoline engine and a propeller at the back. Why does this thing look weird? The deputy director in charge of military affairs can tell a thing or two when taking out a single system, but what is the overall effect of the combination? It's hard to say. "This thing weighs about 145 kilograms and can fly up to 900 kilometers." Sun Aiguo is also learning and selling now.

Boom!

The deputy director of the military department was so frightened that he jumped up, and then his head came into contact with the roof of the car. Fortunately, there was a layer of heat insulation inside the roof of the car, and the innermost layer was a layer of cloth, which could not cause any damage. How much damage.

"How much?" the deputy director in charge of military affairs asked in a slightly loud voice, regardless of the frightened security guard driving in front.

"145 kilograms and a flight distance of 900 kilometers. Do you think if we had this thing back then, would all those guys on the peninsula have rolled into the sea?" The deputy director in charge of military affairs also participated in the peninsula. Action, that's why Sun Aiguo said this.

"More than that, go directly to the notebook. Is this what Comrade Liu Hai said?" The deputy director in charge of military affairs was still a little unconvinced.

"Of course Comrade Liu Hai said it. I don't know much about these things. No matter how you look at them, they all look like a hodgepodge."

"But Comrade Liu Hai said that the accuracy of inertial guidance is relatively poor. The farther the flight distance, the greater the error. Errors of several hundred meters are more common." Sun Aiguo explained.

"What are you afraid of? Can it be used as an ultra-long-range rocket? Let's launch 200 rockets to hit a target, and there will be a carpet explosion." The deputy director in charge of military affairs now realized that this thing is not just for carrying Is it a guidance system, a power system, and then a rocket with wings? It is easy to understand this way.

"Comrade Liu Hai also said the same, and this kind of attack is mainly aimed at high-value targets, such as stations, airports, power stations, oil depots, military camps, or important transportation hubs. These targets are not only large, but also valuable." Sun Aiguo nodded. , everyone has the same opinion.

"But which department should manage this thing?" Sun Aiguo then asked a more troublesome question. It can be predicted that this thing is highly confidential.

No one else will know about it until it's actually applied.

"This matter must be kept highly confidential. We must pay attention to collecting detailed maps of surrounding countries. Inertial guidance completely relies on high-precision maps." The deputy director in charge of military affairs nodded.

When it comes to high-precision maps, the map in Liu Hai's hand is the most accurate.

The aircraft carrier has a high-precision map of the world. As long as the target is determined, Liu Hai can find the current location of those targets on the high-precision map.

In addition, the inertial guidance made by Liu Hai himself is definitely the most accurate.

The reason why the inertial guidance in this era has relatively large errors is that the accuracy in all aspects is relatively low.

The first is the map. The current map is not as accurate as the map in 2020.

The other is the inertial guidance system itself. However, Liu Hai estimated that the flight would be 900 kilometers, so there would still be an error of tens of meters.

The aerial scooter can only serve as a large long-range rocket now. Of course, with the continuous improvement of the homing system, the aerial scooter can also be optimized in various ways in the future.

The reason why the current air scooter is heavier than the Witness 131 copied by Liu Hai is mainly because the current guidance system is heavier.

"Thanks to Comrade Liu Hai's proficiency in all aspects, he was able to come up with such a thing." In Sun Aiguo's car, the deputy director in charge of military affairs became more and more fond of it.

"Yes, the more you go on to see Comrade Liu Hai as a versatile person, the more significant it will be. I really hope that he can create more good things in the future." Sun Aiguo nodded.

"Don't say there is a flight distance of 900 kilometers, even if it is a flight distance of 200 kilometers, the superior department leaders will laugh so hard that they can't close their mouths." The deputy director in charge of military affairs certainly knows that the farther the strike distance is, the impact it will have on the morale of the opponent. The bigger.

"Actually, the big error will make everyone around them panic, because they don't know when this thing will fall on them." Sun Aiguo nodded, and that was all he could say now.

Sun Aiguo and the deputy director in charge of military affairs directly approached the leaders of the military department.

The department leader looked at the drawings in detail and rubbed his forehead: "You can make this thing first and let's conduct experiments. Comrade Xiao Liu is awesome!"

The reason why the department leader rubbed his forehead was because he could not express any opinion on this matter.

During World War II, Sandoko's original missile was actually the kind of random missile that made the entire British people tremble, because you didn't know where this thing would land. As long as there was an air defense warning, people in the entire British city would They were all trembling with fear.

Fortunately, Santoku was defeated quickly. If it were delayed for a few more years, the people in England would probably go crazy.

"This thing has advantages, but the speed is low. If used during the day, the probability of being intercepted is higher." Sun Aiguo also knew that the speed of this thing was low.

"Air defense is not that easy to defend against. It's not like we haven't done it before." The department leader shook his head. In the matter of air defense, no matter what time it is, the big will win the small.

Moreover, in this era, there are not that many air defense means, and the radar system is not as advanced as it was later.

But even when it comes to bangs crossing, there are many methods for this kind of aerial motorcycle, but why can't they be applied?

Because the cost of the entire aerial scooter is extremely low, and the slightly longer range anti-aircraft missiles basically start at one million US dollars.

Even individual air defense missiles are expensive to build.

Of course you can take off fighter jets and use cannons to intercept them without any problem.

But the fighter itself also has costs, and the cost of flying is not low.

This thing is just to intercept, and you will suffer a big loss. If you don't intercept, it may cause serious losses.

The key is that this flying motorcycle operates 24 hours a day.

Maybe if it was intercepted in front, it might come again from behind.

Of course, the Phalanx air defense system is a good thing, but it is impossible to equip all of it in our own country. The cost of building this thing is not low, and the cost of use is also not low.

Of course, there is no such Phalanx at this stage, but the accuracy of current aerial motorcycles is also relatively poor.

"Yes, the kind of single-person aircraft we export has made the Bald Eagles very worried." Sun Aiguo said with a smile.

"The key is that this thing is easy to launch. Comrade Liu Hai said that just use a slide rail." Sun Aiguo said again.

"First make the sample, and then we have the experimental data. I believe in Comrade Liu Hai's idea." The department leader did not hesitate at all.

"We think so too." The deputy director in charge of military affairs also smiled slightly. In fact, anything Liu Hai makes can be sampled first, but there are still procedures that should be in place, and reports that should be reported.

After Liu Hai sent Sun Aiguo away, he arranged for the people in the maintenance department to make it according to his own design.

The wings and fuselage bangs are made of fiberglass, which mainly requires models.

As for the two-stroke opposed engine bangs, you don't need to worry about it at all. You just need to give the required parameters to the small aircraft manufacturer.

The small aircraft manufacturer is not in the motorcycle factory now, but in Caofeidian. However, there is no problem with whatever power device the motorcycle factory wants.

So when Sun Aiguo came back, Liu Hai had already made arrangements.

"Just follow your plan." Sun Aiguo nodded with satisfaction when he saw Liu Hai's plan.
