Although the design and construction of submarines is the first time for the Dragon Soul Ordnance Complex, the Dragon Soul Ordnance Complex has strong capital, as well as various advanced technologies and sufficient human resources, so under such circumstances, the development of Jiaolong-class submarines has begun with difficulty.

In addition to the design of the hull, the power plant and systems of the submarine are very important. Just like the power of an airplane, the power system of a submarine is one of the cores of a submarine. In the course of the development of submarines, until the end of the XIX century, submarines received reliable underwater power plants. The first power plant used on submarines was an electric motor that provided electrical energy from a battery.

However, the main disadvantage of the submarine power plant composed of batteries and electric motors at that time was that the continuous working time was too short, generally speaking, the operating time of the battery could only last about two hours for high-speed navigation underwater, and it could reach twenty hours at extremely low speeds.

Later, the submarine surface navigation power equipment was combined with the underwater navigation power equipment to produce diesel-electric submarines. When a diesel-electric submarine is in the surface state or snorkel state, the submarine is propelled by a diesel engine, according to the different design principles of the designer, or the diesel engine directly drives the propulsion shaft, or through the diesel engine generator set, battery, and main motor to drive the propulsion shaft electrically. However, when sailing underwater, all the underwater power comes from the battery pack.

However, the Dragon Soul Ordnance Complex already has experience in the development of diesel engines for tanks, so it is not a big problem to develop a larger diesel engine for submarines. The most difficult thing is the development of batteries and power systems, as well as the development of submarine weapon systems, in these areas, the armament-industrial complex of the Dragon Soul is the first.

Xiao Weiguo, as a future military expert, will certainly not adopt the power design of the diesel engine directly driving the propulsion shaft. Because after the war. Almost all submarines have a diesel-electric propulsion system. It has a set of high-energy batteries, a high-speed diesel engine with a speed of more than 1,000 revolutions per minute, and a dedicated generator. Regardless of whether the diesel engine on board is running or not, the energy of the battery pack can be used to drive individually designed, low-noise propulsion motors, allowing the submarine to dive underwater with low noise.

This is because diesel-electric propulsion systems have many advantages over direct-drive propulsion. Since the diesel engine is not directly connected to the propulsion shaft and propeller, the diesel engine and the hull can be effectively sound-insulated. This makes the submarine a very quiet weapon for underwater activities.

Of course. On the one hand, the design and construction of submarines are underway, and on the other hand, the flying wing bombers of the Dragon Soul Ordnance Complex have also entered a critical stage.

The flying wing bomber is the key project of the Dragon Soul Ordnance Industry Complex, you must know that at this time, although the United States Northrop is also conducting research on the flying wing bomber, but the Americans will not be able to obtain a successful flying wing bomber until the eighties, that is, the B2 stealth bomber. But the Dragon Soul Ordnance Joint is now home to a large number of top aeronautical designers and engineers, such as Messerschmidt, Juncker, Hillem, and the Horton Brothers, as well as Xiao Weiguo, a military expert who has crossed over. So the flying wing bomber project is progressing relatively smoothly.

You must know that at this time, the position of bombers in the war is becoming more and more important, and Germany's blitzkrieg is to rely on the rapid bombing of bombers to open a door to the enemy. The bomber developed into a formidable aerial weapon, as early as the First World War, some countries tried to use heavy bombers to complete strategic bombing missions, such as the German Gotha bomber, but because the bombers at that time lacked sufficient range and power factors. Therefore, it can only serve as a tactical weapon on the battlefield.

But now it's different, the Wind and Thunder jet series engines of the Dragon Soul Ordnance Complex have appeared. And sold to many countries in the world. As a result, many countries are using the Thunderbolt or Thunderbolt engine to develop their own large transport aircraft, bombers, and fighter jets. Of course, there is a strong impetus for the development of heavy strategic bombers, and various countries are vying to develop a new generation of heavy strategic bombers.

This time. How could the Dragon Soul Ordnance Consortium not join! Because their flying wing bombers have an absolute advantage in performance, enough to compare with all bombers. It was the mid-thirties, and the bomber's various technologies had developed by leaps and bounds, and its combat capability had been greatly improved. Heinkel's HE111 bombers have already begun to be deployed. And put into the Spanish Civil War, this special bomber is better than the M30 bomber of the Dragon Soul Ordnance Complex, although it is inferior to the M40 large bomber in terms of bomb load, but because it is a professional bomber, it is much better in terms of bomb delivery accuracy and other aspects.

Therefore, the conversion of bombers with transport aircraft is only a transitional period, and the era of specialized bombers is coming. Originally, the Italian company Savoy Macchidi designed a hybrid cantilever lower wing bomber, a three-engine bomber, similar to the Junkers 52.

Now Germany also has a Thunder series of engines, so Italy also began to design its own strategic bomber. The same is true for Germany, where the Dragon Soul Ordnance Complex has left a lot of important technology and equipment for Germany.

Under such circumstances, the flying wing bomber of the Dragon Soul Ordnance Complex also accelerated its progress, and in the end it only took more than a year to complete the design and trial production.

In January 1936, the first flying-wing bomber rolled off the assembly line. It uses a wind thunder turboprop engine, a total of four, using a pushback method.

By the time this flying wing bomber took shape, everyone was stunned. Because this large bomber did not have a vertical tail, the wingspan of the wing reached more than 30 meters, and four peculiar six-bladed propellers were installed in the rear of the fuselage, above the flying wing. Its peculiar shape amazed the workers who made it.

Soon the day of the first flight arrived. For any one of the aircraft, it goes through a test flight. The same is true for flying-wing bombers. On January 8, 1936, it began to conduct ground gliding tests. On January 15, the flying wing bomber finally taxied 1,200 meters on the runway of Dragon Soul Aircraft Manufacturing Co., Ltd. and took off from the ground to begin its first flight test.

The first flight lasted only 45 minutes, and then the flying-wing bomber successfully landed. The success of its first flight marked a new stage in the development of the world's bombers. (To be continued.) )
