Chapter 220: The Choice of Power
Hitler's German tank development plan is indeed another huge opportunity for the Dragon Soul Ordnance Industrial Complex! Now the position of the Dragon Soul Ordnance Complex in the field of aviation industry has begun to rise to the top position in the world, and when the wind and thunder jet engine and turboprop engine are put into mass production, and the M40 large transport aircraft is also put into mass production, Dragon Soul Ordnance is definitely the most powerful aviation industry enterprise in the world.
However, in terms of land weapons, in addition to the uniqueness of Bofors Defense in the field of small and medium-caliber artillery and assault rifles, the Dragon Soul Ordnance Complex is still a blank in the field of large-scale weapons and equipment for land warfare! If the German tank project launched by Hitler this time is won by the Dragon Soul Ordnance Complex, it will definitely make the Dragon Soul Ordnance Industry a comprehensive ordnance enterprise group. Even, you can take this opportunity to make full use of Hitler's cartel system and merge several small and medium-sized arsenals to further strengthen the strength of the Dragon Soul Ordnance.
Xiao Weiguo knows very well that in the original history of German tank development, there have been many detours, and the most serious mistake is that German tanks use gasoline engines! The advantages of using a diesel engine are numerous, and the Germans will not be unaware that in fact, German diesel engine technology has always been very advanced. It was only because Germany was so short of resources that diesel engines were not popularized in the armored forces.
Although the Germans had to do it as a last resort, the price they paid was too great, and the safety of diesel engines was significantly higher than that of gasoline engines. In the war, German tanks with gasoline engines, once the engine compartment was penetrated, were likely to ignite a fire, which would lead to martyrdom! Poor German supertank ace Wittmann, that's how he died! The torque of the diesel engine is significantly greater than that of the gasoline engine, and the driving power is more surging than that of the gasoline engine.
Germany did not use diesel engines on tanks, on the one hand, because of the lack of resources. Germany's oil has to rely on imports, more is the use of coal to synthesize light fuel oil, diesel to give to the navy, the second is that the diesel engine technology is not mature enough at that time, the volume of the diesel engine with the same horsepower is 1.8 times that of the gasoline engine, the layout is more difficult. The total horsepower is small, for example, the Panther needs a 700-horsepower engine, the 700-horsepower tank has a gasoline engine when the war starts, and the diesel engine reaches 700 horsepower when World War II is about to end. Third, it takes a process to understand the superiority of the tank using diesel engines. The reason why the Soviet Union took the lead in using diesel engines in T34 was not because of any "foresight", but because the Soviet oil refining industry was backward, and diesel was easier to obtain than gasoline. This can be regarded as a blessing for Seon to lose his horse!
However, Xiao Weiguo knows how important diesel engines are to tanks! Therefore, of course, he will not submit a plan for a gasoline engine, and even if the German Ministry of Defense does not adopt the tank plan for a diesel engine, he can develop this tank and sell it to other countries. Even he was wondering if he could build a gas turbine-powered tank, so that the tank at this time could soar at high speed! It's kind of crazy to think about!
In the nearly 100 years from the birth of the tank to the 21st century, the tank engine has generally experienced the "gasoline engine era", "diesel engine era" and "diesel combustion coexistence era". The birth of gas turbines and their application to tanks have brought tanks into the "era of diesel-fuel coexistence". The first to use gas turbines in tanks was Germany in World War II, which conducted relevant research during the war. But with the end of World War II, it was forced to stop. As early as the early 50s of the 20th century, Britain and France began research on military gas turbines. Royce technicians revealed that the British military had developed a 1,000-kilowatt gas turbine at that time. Compared with diesel engines, gas turbines have the main technical and tactical advantages of fast start-up speed, high power density, simple structure, and small additional power loss, but they also have the disadvantages of high fuel consumption. The debate about whether a tank engine should be a gas turbine or a diesel engine has long been debated. But there has been no definite conclusion, the main reason is that neither has completely replaced the absolute superiority of the other at present.
In Germany, the first person who proposed to use gas turbine engines in tanks was Alfred, who was engaged in the research and development of turbojet engines for aircraft? Dr. Müller, who previously worked for Junkers and then Heinkel, considered that turbine engines themselves have a thrust-to-weight ratio that surpasses that of conventional combustion engines. If it could be applied to the tank, it would provide more power to the tank and reduce its weight, and in mid-1943 he submitted a design for the installation of a gas turbine engine for the Leopard tank to the Army Armament Bureau. Although gas turbine engines had the disadvantage of large fuel consumption, due to their multi-fuel adaptability, there was enough kerosene for tanks even at the end of the war, so Müller's proposal has been officially supported.
In order to adapt the aero engine to low-quality fuel, Müller added a rotating fuel nozzle to the BMW 003, and a large amount of exhaust gas generated by the gas turbine will be exhausted through a large exhaust port installed at the rear of the tank. In addition, there is the inherently huge fuel consumption of gas turbines, whether Germany lacks fuel or not, putting it on the tank means expanding the volume of the fuel tank, which means less combat space and reducing the bomb load. So in the end, this plan was forced to be aborted, and now Xiao Weiguo is thinking about whether Dragon Soul Ordnance will succeed if it shrinks the wind and thunder jet engine and designs a gas turbine for tanks?
During World War II, Müller used a hydraulic transmission scheme. The automatic hydraulic actuator of the GT101 was designed by ZF in Friedrichshafen and has a total of 12 speed gears and is electrically automated. When the gas turbine is running at a maximum power of 14,000 rpm, the engine itself can also be used as a huge flywheel, accumulating a lot of kinetic energy and thus providing very good maneuverability. The efficiency of the GT101 system is very good, the BMW 003 can provide a total of 3,750 horsepower, of which 2,600 horsepower will go back to drive the engine's compressor and 1,150 horsepower will be transmitted to the gearbox, while the total weight of the entire propulsion mechanism (except for the gearbox) is only 450kg. Of course, the Thrust of the Thunder Jet Engine is much greater than that of the BMW 003, which means that the power is also much greater, so it has to be scaled down to be used in tanks.
