Chapter 410 return to Dongchen hanggong

The infamous Nippon Steel was successfully taken over by Dongchen. There seems to be no excessive surprise around the world for this news, because their attention to Dongchen is all focused on one thing, that is, Australia's overall compromise with Dongchen.

Walter, the Australian ambassador who was called by Zhang Yunfeng as Dongchen's old friend, became the signing representative of the cooperation between the Australian government and Dongchen. Among the many contracts, the most surprising one is that Australia has ceded all the iron ore production capacity of the whole Western Australia to Dongchen. Since then, all the iron ore produced on its own land, its own minerals and others have to go to others Dongchen now has the largest iron ore resources in the world.

In return for the Australians, on the day after signing the contract, Dongchen dispatched 50 7478 freighters, which were full of Dongchen's full range of products. Between China and Australia, it flew more than 200 sorties continuously.

In just a few days, Dongchen's sales volume in the Australian market is nearly 100 billion dollars, 20 billion dollars of orders for aeroengines, 50 billion dollars of universal products, and nearly 10 billion dollars of Dongchen home appliances and nearly 10 billion dollars of Dongchen cars.

After looking at the sales data of Dongchen in Australia in recent days, the Australian government is embarrassed. Even the Australian government can't figure out why it has given up so many benefits to beg Dongchen to come to Australia to earn more benefits. This feeling is like spending money to ask thieves to steal more property from their own home Sample.

At this moment, for Zhang Yunfeng, Dongchen has once again completed a new leap. The civil aircraft engine covers all the needs of the whole industry. Through the OEM of Dongmu, Dongchen's production capacity has increased dramatically. And Dongchen itself has also completed the global iron ore industry. Now, Zhang Yunfeng can finally take the time to carry out the next development of Dongchen, That is, the development of Dongchen in the military field.

Developed countries all over the world, especially big military countries, are making great efforts to develop their own military aircraft engines. At this time, if Dongchen doesn't move any more, the combat effectiveness of China's fighters will be pulled apart by other countries. Since those big military countries are worried that Dongchen will develop military engines, it's also time for them to feel what it means to dream It's a dream come true.

The matter at hand has come to an end for the time being. Zhang Yunfeng is ready to leave for Zhonghai. Shenyang Aircraft Engine Research Center has transferred all its production equipment to Zhonghai and incorporated it into the production line of Dongchen aviation engineering. Everything is ready, waiting for Dongchen to start the research and development and production of military engines.

Zhang Yunfeng doesn't need to research and develop. He just needs to consult with the junior two about what kind of engine he should take out to meet the military's demand for the power performance of the fighter.

The junior two analyzed the performance and bottleneck problems of all kinds of military fighters at present, and said: "boss, let go of other parts such as combat and avionics. When it comes to power performance, I think it's nothing more than focusing on three elements, one is fast, the other is far, and the other is heavy."

Said, the second explained: "fast means flexibility, fast speed, and the pace of cutting in and out of the battlefield is faster. When fighting in the air, it can also make a quick and flexible response."

The area is large enough, and a larger battle radius can be used to exchange a larger safety space for the aircraft carrier. "

"As for the weight, it's also very easy to understand. It determines whose aircraft has stronger bomb carrying capacity. Two aircraft, one can only hang four to the ground missiles, one can fly to bomb four targets, while the other can hang eight to the ground missiles, one can fly to bomb eight targets, which determines the fighter's attendance efficiency. These three standards all come from the aircraft's movement Force performance, however, these three kinds of performance can not be combined. If you want to fly faster, the combat radius of the aircraft must be affected, because the faster any object moves, the greater the energy consumption... "

Zhang Yunfeng impatiently waved his hand and said: "waiter, can you say something I don't know? What you said, kids all know that there is a very obvious gap between the energy consumption of cycling at a constant speed and that of cycling at a high speed. As soon as I learned how to ride a bicycle, I've learned that I don't even need to pass the super learning system. "

The second one smiled awkwardly and said: "the eldest one is wise, in fact, I mean, we can't develop an engine that takes all three into consideration, and shenfa's production capacity is also very limited. If we spread the product line, I'm afraid it's hard to see the actual effect in the short term. It's better to focus on one engine in the early stage."

Zhang Yunfeng nodded and said, "in your opinion, which one is the most needed and practical in China?"

The second one thought about it and said: "there are many imaginary enemies and defense focuses, but in terms of air defense, the main threat we face is from neighboring countries, such as dongdau, India and E Low fuel consumption engine, but also a little emphasis on push to weight ratio, after all, push to weight ratio has always been the weakness of domestic fighters. "

Zhang Yunfeng frowned and said: "in this way, we can meet the need of thrust to weight ratio without reducing the fuel consumption to the lowest level and sacrificing part of the fuel consumption to increase the engine thrust. After all, the thrust to weight ratio is not a blind pursuit of large enough. As long as the thrust to weight ratio of the whole machine can be greater than 1.3, it is very powerful."

The thrust to weight ratio mentioned by Zhang Yunfeng refers to the relationship between the engine and the maximum load of the whole machine. If the thrust to weight ratio of the aircraft is 1.3, it is equivalent to that when the aircraft reaches the maximum design load, the thrust of the aircraft is 1.3 times of the maximum load.

If it is a transport aircraft, airliner or ordinary cargo aircraft, the thrust weight ratio of this kind of aircraft is less than 1, that is to say, the actual thrust of these aircraft is smaller than the weight of the maximum load of the whole aircraft. In this case, the aircraft can take off by sliding and climb at a certain elevation angle, but it is impossible to achieve a vertical climb of 90 degrees. However, this kind of aircraft does not need to have a vertical lift at all The ability of vertical climbing is different from that of fighter. In actual combat, the ability of vertical climbing is very important. A push to weight ratio greater than 1 can make the aircraft quickly get out of the vision of the other party in the way of vertical climbing. If the climbing is reversed and the height is lowered, it will be behind the butt of the other party, and the missile of the other party will lose its function completely at this time.

In many cases, if the thrust to weight ratio of the fighter is greater than 1, the thrust of the whole machine will be very strong, while Zhang Yunfeng will prepare a new engine to ensure that the fighter has at least 1.3 thrust to weight ratio.

The waiter replied: "the push to weight ratio of 1.3 is not difficult. Even if we achieve the push to weight ratio of 1.3, our engine can reduce fuel consumption by about 30% and increase the combat radius."

Zhang Yunfeng nodded, frowned, and said to himself: "the speed problem seems to not be solved by the weight ratio. It needs the engine to have enough explosive power and can be raised to the fastest speed in the shortest time. To meet this requirement, it can only be solved by the afterburner. Sophomore, do you have better afterburner technology? If there is a better afterburner technology, then we can do three things at the same time! The engine is designed to be far and heavy. Then, through the fixed configuration of the afterburner, if the aircraft needs speed and mobility, open the afterburner, increase fuel consumption, and improve the speed of the aircraft. "

Small two eyes a bright, smile way: "this is a good way! How could I not think of the afterburner? If we match with better afterburner technology, the design of afterburner can ensure that the aircraft has enough range to push weight ratio when it does not need to start the afterburner at ordinary times. Once it needs more maneuverability, it will open the afterburner to sacrifice the range for more maneuverability! "

Zhang Yunfeng said: "the design of the afterburner must be the simplest and lightest, so as not to bring more useless weight to the aircraft, increase fuel consumption and affect the voyage most of the time."

Xiaoer said with a smile, "the afterburner equipped with a single engine can gain up to 100kg, with little impact."

"That's good." Zhang Yunfeng nodded his head with satisfaction. If it is designed according to this way, this power system is probably the most powerful fighter power system today. Even if it is inclusive, it can only catch up with others. So, once this power system upgrades the domestic fighters in an all-round way, its deterrent power to the neighboring countries will be further enhanced, Significant.

Zhang Yunfeng's special plane arrived at COMAC's test flight airport in Zhonghai, which has been taken over by Dongchen. Although COMAC didn't know that Zhang Yunfeng was going to acquire Airbus's top secret plan, the senior management also stopped the funding and related research and development work for COMAC. COMAC has now suspended its big plane plan, and the whole COMAC is still in operation The production is nothing more than some small regional airliners that have already been finalized. Even if there are new regional airliners that need to be tested, COMAC has no choice but to transfer to the northwest airport and leave the airport in Zhonghai to Dongchen.

The whole aircraft team of Dongchen has almost taken off and landed at the commercial airport of China Sea. Numerous engines of Dongchen hanggong are also installed here in Boeing 7478 transport aircraft to fly to all parts of the world. Zhang Yunfeng is also going to develop this place into the aviation hub of Dongchen in China Sea, and gradually add relevant auxiliary equipment for freight transportation, apply to the high-level, expand the area and build two new ones For the same standard runway, hangar and other hardware facilities, there is another thing Zhang Yunfeng has been planning. That is to build a large-scale logistics distribution center near the airport, and try to apply to the senior management to build a railway connection line at the airport to connect the Beijing Shanghai railway. Once the Beijing Shanghai Railway is connected, even if it is connected to the national ordinary railway network, if it can be connected to the Beijing Shanghai high-speed railway Iron, then it is connected to the national high-speed railway.

If these two connecting lines can extend to Dongchen's airport, Zhang Yunfeng, the logistics distribution center, can achieve unprecedented efficiency in the logistics industry. The goods entering the port can be dispersed by road and railway in the shortest time, and the goods from all over the world can also
