My Black Tech Shelter

On September 2nd, after getting up, Lu Chen checked the progress of the drone's high-lift rotor deduction and found that Zero had already deduced three plans. One was to increase the ceiling to four thousand meters, and the power consumption was higher than before. 50%, the second one is that the ceiling is raised to six thousand meters, on the basis of the 50% increase in power consumption, the manufacturing cost is also increased by 50%, while the last one is higher, the ceiling is raised to 10,000 meters, while power consumption and manufacturing costs were increased by 100%.

Lu Chen saw this data, thought about it for a while, and finally chose the second option, which increased manufacturing costs and power consumption by 50%. The first data increase was too low and would have to be improved again later, while the second option was six One thousand meters is enough. As for the last ceiling of 10,000 meters, it is a bit wasteful. Ten thousand meters is equivalent to 10 kilometers, which is a distance of 10 kilometers. The electromagnetic gun that comes with the rotor drone is completely It is redundant. With the size of the drone, it can evade most attacks at a height of 6,000 meters. But wouldn’t it be nice to use a fixed-wing drone at an altitude of 10,000 meters?

So after choosing the second option, Lu Chen manufactured a batch of new rotors and replaced all four drones patrolling outside. The rotors of the replaced drones were not scrapped. After all, their performance It was pretty good. Lu Chen re-stored and packaged the replacement rotors and prepared to go out in a few days as exchange materials. After all, the previous drones may not be usable on this day.

Lu Chen then planned to study fixed-wing drones. Currently, fixed-wing drones use petrol power, electric power and petrol-electric hybrid power. Electric power drones have a shorter range, so the mainstream ones are still petrol power. power and gasoline-electric hybrid power. What Lu Chen currently lacks is fuel, so he can only vigorously develop electric engines.

Lu Chen checked the relevant development history of drones through Zero, and also found some information on electric engines and turbojet engines for research. Through research, Lu Chen found that the electric turbojet engine he originally thought of was currently not possible. , the traditional turbojet engine enters the air through the air inlet, and then transports the pressurized gas into the combustion chamber. After the gas is heated and expanded, the gas is sent to the turbine for discharge. If electric power is used, the gas can also be heated and expanded to reach Such an effect, however, cannot achieve a better cost performance than using fuel turbojet due to the existing battery energy density and heating methods, so it is currently only in the state of laboratory research.

Lu Chen then searched for piston engines from the Second World War and found that the performance of the piston engines could meet his current requirements. For example, the Mustang fighter jet can reach a speed of 703 kilometers per hour and has a ceiling of 12,800 meters. The range is more than 1,500 kilometers. Judging from this data, based on your current needs, it is still possible to apply the technology to fixed-wing drones.

Lu Chen then logged into the current Longguo network through the quantum communication network and found information about the Mustang fighter, mainly its aerodynamic layout. Then Lu Chen began to design the drone with the help of Zero. First, he calculated the previously calculated data. The third type of rotor was modified and turned into a propeller aircraft motor, replacing the piston engine. Then the fuselage began to be designed with reference to the Mustang's aerodynamic layout. Hidden weapons also needed to be installed, including high-altitude fast cameras, which were also studied. ,

After a day and night of research, Lu Chen finally designed a propeller drone. Looking at the weird drone on the holographic workbench, Lu Chen always felt a little awkward, "The pigs in the science and technology novels I read before" Feet, which one is not capable of flying in the air every second, why is it so difficult when you practice it yourself? "

Lu Chen sighed, authorized Zero to log in to his account and continued to search for information on the network. Due to the solar storm, the last remaining wired network was destroyed. Although the database was protected and everything was fine, the data transmission lines were destroyed. , so Longguo used the existing quantum communication network to re-build a small-scale local area network, and then re-uploaded regular data into it, and major companies also used quantum communication to re-establish their own websites.

Since Lu Chen's previous transactions were of great concern to the state, Lu Chen was given an account to log into the electronic library established by the state. With Lu Chen's authority, except for some confidential high-tech technical knowledge, all theories were available. It is open to him, and the country does this in the hope that Lu Chen can make more inventions, so that both parties can be mutually beneficial and get what they want.

Now Lu Chen lost his account to Ling and asked Ling to find some information on electric aero engines on the Internet and in the library, including concept drawings, etc.

With Zero's search, the storage content in the computer room in the shelter is gradually increasing, and Zero's database is also constantly enriched.

After a while, Zero has downloaded the data of the electric aero engine, including the layout of some aero engines conceived by others, and used them as data for deduction and calculation. Finally, Zero provided Lu Chen with two feasible solutions.

One solution suitable for small and medium-sized fixed-wing UAVs is to use electric ducted fans, which can be directly used on small and medium-sized UAVs. Because the thrust is limited, it was directly abandoned by Lu Chen, while the other is to use vortex fans. The working principle of the jet engine is based on the above, but on this basis, the combustion chamber is replaced by an electric heating chamber. Efficient electric heating is used to heat the compressed gas and discharge it from the turbine. This conversion will cause a certain amount of energy loss, and the efficiency is higher than that of the traditional The turbojet engine is much cheaper, but the advantage is that it can use pure electric power without using fuel.

However, after asking Zero to make calculations, Lu Chen found that with his existing technical reserves, he could not realize this idea. The power supply and energy were too low to meet the requirements. However, Lu Chen saw an introduction to the ion engine in Zero's database. , the prospects are very good, but we will talk about this later.

After there was no better electric engine, Lu Chen began to change his original intention of using fixed-wing drones. The original idea was to use a fast support equipment to make up for his shortcomings in long-distance support. However, for the time being, he can only use propeller drones. If you have a gunship, you can refer to the AC-130 gunship.

Lu Chen also knew about the mutated ants previously reported by the official. Later, he asked the officials for the video of the battle at that time. Looking at the ant nest in the bait trap, Lu Chen felt a sense of crisis in his heart. Although the territory of Dragon Kingdom was basically cleaned up, But there is no guarantee that no fish will slip through the net, and if new mutant beasts appear in the future, can we only rely on official rescue?

Moreover, Lu Chen has received official authorization and a license to manufacture and develop weapons. This is a privilege for geniuses. Some important corporate shelters also have gun licenses, but they are only for pistols.

Even so, if Lu Chen built a killer weapon like an aerial gunship, the officials would probably be upset, so Lu Chen was also considering what price to pay to get the officials to relent.

Of course, when considering these, Lu Chen did not stop and continued to design with Ling's cooperation.

After several hours of adjustments and modifications, Lu Chen designed the prototype of the unmanned gunship, and then began to simulate flight on the holographic workbench. The final data displayed was that the ceiling was 10,000 meters and the flight speed was 600 kilometers per hour. , the empty take-off weight is 700kg and the range is 3000 kilometers; the fully loaded take-off weight is 2 tons and the range is 1500 kilometers.

Finally, Lu Chen combined his own electromagnetic gun technology with Gatling gun technology to create a multi-barreled electromagnetic gun using 10g projectiles with a firing rate of 2,000 rounds per minute. Later, Lu Chen built an unmanned gunship After modifications, two multi-barreled electromagnetic guns were installed on each side of the gunship. Lu Chen then added 100,000-pound bullets and an automatic ammunition supply device. Finally, the wind weight reached 1.8 tons.
