There are so many things happening recently. Liu Jinpeng heard from Li Xiwen that Pingjing Qingyi Garden had already started to prepare for the preliminary preparations, and Li Jingwen also called Liu's parents to come to Pingjing, and both sides wanted to talk about the marriage of the younger generations. Liu Jinpeng made a mistake at the time and said that his father would retire in less than two weeks, and he would go to Pingjing immediately after retirement. As a result, Li Jingwen had to accommodate and wait for a while.

Then there is a test report from the Seventh Army, which shows that the quantum communication system has good prospects for military application, at least with no problem of confidentiality. This report was submitted to Qingyiyuan, General Staff and General Equipment Department in triplicately. Li Jingwen believes that experimental installation can be started in the army, and the Northern Army Group stationed in northern Xinjiang was initially selected, and neither the General Staff nor the General Staff expressed any opinions on this.

This default attitude obviously does not want to offend either party, and does not want Qingyiyuan to take this attack, nor does it want the public relations group to admit failure. This is their embarrassment. Read the full text of Yan Liang, the tyrant of the Three Kingdoms. However, according to Liu Jinpeng's estimate, it will be difficult for the General Staff and General Staff to not express their opinions after the Northern Army Group installed quantum communication equipment. Sooner or later, it is better to firmly support one party from the beginning.

In addition to these things, the Navy's test of electromagnetic guns has also been completed. The report mentioned that in the onshore gun test, in the test exceeding the maximum shooting distance of the gunpowder gun, the hit rate of 252 shootings exceeded 98%, and the accuracy is much higher than that of the gunpowder gun. In terms of damage, the damage of electromagnetic guns is comparable to that of gunpowder weapons, but this is a comparison of different calibers. If the caliber of electromagnetic guns can be further improved, the damage will inevitably be higher than that of gunpowder weapons.

He Feihu is now pushing for electromagnetic guns to be launched. The General Equipment Department has approved a package of plans proposed by the Navy, including the construction of the test ship Yumenguan. The destroyer will install two 120mm electromagnetic guns as main guns, and also have 8 90mm electromagnetic guns as secondary guns. It is planned to replace medium and short-range missiles with electromagnetic guns. The destroyer itself cannot carry too many missiles. The modified electromagnetic gun system will more than double the amount of missiles than the missile system.

The package also includes suggestions for installing UFO drones from Yumenguan. At the same time, it proposes to acquire some civilian technologies to strengthen the military's shortcomings in certain fields. This vague clause is basically specially prepared for Titanium Star Group. He Feihu believes that Titanium Star Group can definitely give some rational suggestions, which would be better if there is an updated technology.

Liu Jinpeng did not make any suggestions for this package. He actually felt that it was a bit out of place to build traditional surface ships when the anti-gravity engine was gradually improved. For example, the 100 ground effect aircraft purchased by the Navy in May this year were very creative. This batch of wing-effect spacecraft had a ceiling of 1 to 4 meters, a speed of 280 kilometers per hour. It carried 12 people nuclear and consumed 28 liters of fuel per hour.

The ground effect is a type of airframe boost that was discovered very early. It is a fluid mechanical effect that reduces the induced drag of the aircraft and can obtain a higher lift-to-resistance ratio than in air flight: when the moving aircraft falls very close to the ground (or water surface), the up-down pressure difference of the entire aircraft body increases, and the lift will suddenly increase.

The ground effect has not yet been concluded in physics. But this does not prevent engineers from creating machines that can use this principle. The latest domestic wing-effect spacecraft is the one purchased by the navy, and to some extent it is the most practical wing-effect aircraft. In the past few years, Goryeo claimed to have built wing-effect aircraft that can fly at the limit of 150 meters, but that type of aircraft has only symbolic meaning and cannot be practical.

Russia is currently the fastest-track researching ground-effect aircraft in the world. Their wing-effect aircraft can already fly stably at an altitude of about 10 meters, and for the first time the load capacity of the aircraft exceeds 60% of the body weight. This is a big breakthrough. The load capacity of an ordinary aircraft is only about 20% of its own weight, while the load capacity of domestic wing-effect aircraft is only 50%.

The advantage of ground-effect aircraft is that it can fly at ultra-low altitudes, and there is no need to worry about the impact of terrain. Whether it is oceans, deserts, plains, or hills, it will not affect the use of ground-effect aircraft. At the same time, ground-effect aircraft can also hover, retreat, sideways and other actions that ordinary aircraft cannot do, which is of great use for rushing into enemy territory to reconnaise, or avoiding radar to transport troops.

Unlike traditional hovercraft, hovercraft can only maintain a distance from the ground by jets. Moreover, hovercraft cannot cope with complex terrain and have no resistance to waves. The ceiling of ground-effect aircraft is very large, and ordinary waves have no impact on it. The load capacity of ground-effect aircraft is stronger than that of hovercraft and much faster. The speed of ground-effect aircraft is 10 times higher than that of ordinary ships, 2 to 5 times that of motorboats, and there is no loud noise.

But after saying so many benefits, the disadvantage of ground-effect aircraft is not that it has no high-altitude flight capability and can only fly in the air below 150 meters. Generally speaking, the wingspan of a ground-effect aircraft determines the altitude of its stable flight. A simple judgment formula that is one-half of the wingspan is the stable ceiling.

Therefore, compared with anti-gravity aircraft, the ground-effect aircraft is still in a backward situation. The anti-gravity aircraft can complete all the actions of the ground-effect aircraft, and even the appearance does not need to be a streamlined type like the current aircraft. The anti-gravity aircraft can maintain a high ceiling, and as long as the pilot can bear it, 20,000 meters will not be a problem.

The noise of anti-gravity aircraft is lower than that of ground-effect aircraft. The carefully adjusted engine can be kept silent, and its energy consumption and speed are not inferior to ground-effect aircraft. However, Liu Jinpeng is not in a hurry at the moment. There are always stubborn forces in opposition to technological progress.

At present, Yiti is preparing to launch a probe to the moon. The preliminary plan is to use the anti-gravity engine to test the opportunity to bring it to the stratosphere to launch, but later Liu Jinpeng proposed a new idea, which gave Yiti a good inspiration to read the full text of Tianmu.

The new idea is to launch probes to the moon using electromagnetic cannons to launch projectiles. The source of the idea is a series of games called "Borderlands". In this game, the transmission robot to the planet's surface is to use a catapult device to land hard, and the containers that transport materials are also delivered by a catapult launch hard landing.

After considering this plan, Yiti believed that it was indeed feasible. The design of the buffer device can ensure that the container remains intact when it arrives on the moon, provided that the container is not too large. It is well known that the larger the object is emitted, the more energy it requires. The electromagnetic gun must also respect the energy law, even if it is added with an anti-gravity engine.

The lunar probe itself is not large in size, with an energy pool powered by power, and a communication terminal provides rear contact function. In addition, there are acquisition devices, simple analysis devices, etc. The detector itself must have complex terrain processing capabilities, so Yiti designed a crawler type. As long as there are not too large holes, the crawler type can ensure walking stability.

The only problem with this plan is that the moon always faces the earth at the same time. If a probe is launched from the earth, it will inevitably land on the front of the moon, rather than on the back of the originally planned moon. The time it took for the probe to walk to the back of the moon was too long, which obviously did not meet the planned arrangements.

Liu Jinpeng’s solution to this is multi-level propulsion. He explained to Yiti: “The purpose of our use of electromagnetic emission devices is that it requires too much conventional energy to break through the second cosmic velocity. Once the electromagnetic emission method is used to break through the second cosmic velocity, once the moon is approached, you can directly use multi-level propulsion method to change the motion trajectory.”

This method can change the course of the detector to the back of the moon, but it must also be careful not to make the detector become a satellite orbiting the moon, which would be equivalent to a failure in launch. Multi-stage propulsion is a bit difficult for electromagnetic emissions. Liquid fuel is obviously not the first choice, and solid fuel thrusters are more suitable for this kind of launch method.

The launch preparation of the detector has been completed. By the time the first batch of energy batteries on the sea floating island are shipped, the energy of the Titanium Asterisk can be replenished to a sufficient level of launch. The current core skeleton of the sea floating island has been built and after filling with foam materials, it is currently being transported to the selected island. The waveproof wall has been completed by one quarter, and it is indeed very convenient to spray and condense into a wall.

The disadvantage of this kind of waveproof wall is that it is afraid of fire. Fortunately, the possibility of burning on the sea surface is too low. Each floating platform is connected with fixed cables, and the stone anchor and steel wire rope are a general design. The energy cables that Liu Jinpeng mentioned at the beginning also have a small number of applications, which looks a bit sci-fi under the sea surface.

Thanks to the supervision of Liu Jinpeng and Li Xiwen, the construction of the platform on the floating island on the sea has accelerated its progress and is expected to be completed in more than a month. The installation of equipment takes much more time than filling foam. It takes more than 70 days to calculate from the skeleton to the sea.

After another day of busyness, when he returned home, Liu Jinpeng found that there were a few more mouths at home today to eat. Wu Xinrui, Huo Zijia and Jiao Jiao gathered in Meishan Villa in a rare manner. These three girls are very busy now and have fewer opportunities to eat in the villa. After entering the door, he found that the living room was so noisy. When he saw it, he found that these women were chattering, which was even more irritating than the TV guy.

Seeing Liu Jinpeng coming home, the seven girls stood up to greet him, which made him happy for a while. However, Meiling and Meihua missed the welcome ceremony because they were still students and needed to do homework. Wu Xinrui was the most heartless and laughed at her cousin and said, "I heard from my sister-in-law that you are going to get married soon. Oh, my third aunt finally hoped for this day, and she didn't know how happy she was."

Liu Jinpeng counterattacked in disappointment: "I don't know how my aunt arranged your marriage. You are a big girl, so you can't delay it anymore."

Wu Xinrui didn't care about this, hugged Huo Zijia and said, "I made an appointment with Jiajia and I won't get married."

Huo Zijia quickly shook Wu Xinrui away and said in a word: "That was ignorant when I was a child, don't blame me."
