The Dragon Soul Ordnance Complex is already a giant in the world's ordnance industry, but Xiao Weiguo did not stop, he then began to develop the world's first missile! It is a ground-to-surface missile designed using the technology accumulated from rocket artillery.

The missile is an unmanned weapon that relies on the guidance system to control the flight trajectory and can designate the target and even track the movement of the target, and its task is to detonate the warhead charge near the target and destroy the target, or rely on its own kinetic energy to directly hit the target without a warhead to achieve the effect of destruction. In short, a missile is a weapon that relies on its own power plant to propulse, and is guided by a guidance system, controls its flight path, and directs it to the target. So the development of missiles at the end of the thirties, is definitely a huge challenge.

The V2 missile is a single-stage liquid ballistic missile developed and used by Germany during World War II. It was the world's first surface-to-surface ballistic missile. The total length is 14 meters, the weight is 13 tons, the diameter of the bomb is 1.65 meters, the wingspan of the bottom tail is 1.95 meters, the warhead weighs about 1 ton, and the middle part of the bomb body is a shell structure, with an oxidizer tank and a fuel tank inside, which contain 5 tons of liquid oxygen and 3.5 tons of alcohol, respectively. The V-2 missile has a thrust of 260 kN (ton), a maximum flight speed of 1.7 km / s, a maximum range of 320 km, a flight duration of about 320 seconds, and a hit accuracy (circular probability deviation) of 5000 meters.

Xiao Weiguo, of course, will not design this missile after Germany, because its performance is too poor. The 13-ton missile has a range of only 320 kilometers, and the hitting accuracy is too poor, even if it is a large-caliber rocket artillery, the error will not be so large. For example, the later Chinese WS-2 rocket has a diameter of 400 mm, a total weight of 1285 kg, and a total length of 7302 mm. The firing range reached 360 km. It weighs only one-tenth of the weight of the German V2 missile in World War II, but has a longer range because it uses solid fuel and a solid rocket engine, which not only has a long range but also has a short preparation time for launch, unlike the V2 that needs to be refueled before launch. It consists of a fuse, a warhead, a control system, a solid rocket engine and a projectile structure. Maximum flight speed Mach 5.6. The firing accuracy is about 600 meters, far exceeding the German V2 missiles in World War II.

Of course. It is obviously impossible for the Dragon Soul Ordnance Consortium to come up with a rocket artillery or missile like Guardian 2, and the current technical conditions cannot be met. However, to make a missile that is much more advanced than the V2, it is possible.

Because Germany was developing V2 missiles at this time, Xiao Weiguo had to crush Germany in this aspect, so that Hitler, a war maniac, could automatically give up the idea of aggression.

According to Xiao Weiguo's memory, at the beginning of 1936, Dornberg and von ? Braun and others began to consider developing a large, practical A-4 rocket. That is, the V-2 rocket, which was later named. Using the most powerful German-made "Paris Cannon" at that time, they determined the initial performance parameters of the A-4 rocket.

According to this, the artillery expert Dornberg proposed the technical indicators of the rocket: "The First World War developed the Paris cannon, which can launch shells with a diameter of 21 centimeters and a charge of 22 pounds to 125 kilometers, and the new rocket should carry 1 ton of explosives and fly twice as long as this, that is, 250 kilometers, it should meet the conditions of road, country road and long-distance rail transportation, and its maximum size should be determined according to the curvature of European tunnels and railways." After preliminary calculations. The width of the rocket, including the tail, should not exceed 2.74m, and the total length should not exceed 12.80m. Based on this, the researchers deduced a series of technical indicators. Such as the total weight of the rocket, thrust, launch accuracy and fuel combustion speed. These indicators became the basis for the design of the A-4 rocket.

As a large rocket, the A-4 rocket has a great technological leap compared with the previous experimental rockets, and has encountered many unprecedented problems in its development, involving a large number of basic theoretical and experimental technical problems. Due to the scarcity of relevant research literature, the developers decided to start with basic research and explore the technology required for large rockets from all aspects. They focused on a series of major issues such as high-speed aerodynamic design, high-thrust engine design, combustion control, propellant control, injector design, and ballistic control. Many technological breakthroughs have been achieved.

The total length of the fuel tank of the V2 missile or A1 rocket is 6.21m, which is the largest and heaviest part of the rocket, and the weight accounts for about 2/3 of the total mass of the rocket when it is filled with fuel. The fuel tank is divided into two fuel tanks, the upper part is an alcohol tank. The lower part is a liquid oxygen tank. A conduit is led out of the alcohol tank and through the liquid oxygen tank to deliver fuel to the combustion chamber. Between the two fuel tanks, as well as between them and the rocket casing, fiberglass is filled to insulate the heat. The tail section mainly contains a turbopump unit, a steam generator to drive the turbine, two small boxes containing hydrogen peroxide and ******** respectively, and a rocket engine. The tail section is symmetrically equipped with 4 stabilizing wings with a length of 3.95m, the trailing edge of the tail is equipped with controllable aerodynamic wings, and there are also 4 gas rudders symmetrically installed at the bottom nozzle of the rocket, which are used to adjust the flight attitude.

The A-4 rocket was complicated by engineering. In addition to rockets, there are also a series of supporting facilities for the development and other work, such as fixed launch pads, vehicle-mounted mobile launch pads, fuel filling facilities, power supply facilities, radio receiving stations, ground observation stations, large-scale production and equipment of troops, and so on. The fixed launch pad is an underground bunker, which is easy to be found, and the Germans actually use more vehicle-mounted mobile launch pads, which are a universal ring fixed on a bracket and equipped with an ignition device, which can turn the rocket from a horizontal launch state to a vertical launch state.

Hitler wanted to provoke another war with the armament of V2 missiles. However, how did he know that the Dragon Soul Ordnance Complex was also developing a surface-to-surface missile that was much more advanced than the German V2 missile at this time. Even if the Dragon Soul Ordnance Complex does not develop missiles, it is obviously impossible for Germany to compete with various advanced fighters in the air with a ground-to-ground missile.

The surface-to-surface missile developed by the Dragon Soul Ordnance Complex uses solid fuel and a solid rocket engine because it weighs much less. The design indicators are also very high, the missile is 7.2 meters long, the diameter of the missile is 420 mm, the weight of the projectile is 2500 kg, the maximum range is 300 kilometers, the deviation is 1500 meters, and each launch vehicle can be loaded with 3 missiles.
