The history of gas turbine development in China is a history of the struggle and growth of domestic scientific researchers, and it embodies the unwillingness and imagination of the Chinese people.
Facing ridicule and pessimism, we face challenges head-on.
We are now at the beginning of seeing a glimmer of hope. Although domestic gas turbines are not yet advanced enough and their efficiency is still very low, the foundation has been laid, and localization has been achieved, marking a leap forward from zero to something.
Those who laugh at domestic copycats are completely idiots. Which of their neighbors is so generous as to reveal key technologies and allow domestic copycats to copy them?
If efficiency is low, then improve it. Continuous optimization will eventually lead to a global presence and a global leadership. This foundation is built on Wu Tong's involvement. Wu Tong will undoubtedly want to accelerate this optimization process and push efficiency to the maximum achievable level.
This is also the pursuit of her design, infinite quasi-perfection, with her current level of perfection. When her knowledge system breaks through, this quasi-perfection state can be further optimized!
Wu Tong decided to start with gas turbines as a transitional technology before advancing.
It's not that she can't develop a nuclear-powered aircraft carrier, but according to her next major project, nuclear fission-powered aircraft carriers are expensive and have no future prospects, so it's not worth the effort. Of course, if there is a real need for this in the country, then we can increase research and development!
Secondly, there are also many outstanding scientific researchers in China who have made breakthroughs in overtaking others. Mr. Ma’s ship integrated power system is one of them. It combines the traditional ship’s independent mechanical propulsion system and power system into one in the form of electrical energy, and provides electricity for ship propulsion, communication and navigation, special operations and daily equipment through the power network, realizing the comprehensive utilization of energy throughout the ship.
If it can be equipped with a better and more powerful gas turbine, the positive results that can be achieved may be greater than the combination of the two swords!
The birth of ship integrated power systems is fundamentally due to the fact that since the end of the 20th century, with the rapid development of marine development and coastal defense construction in various countries, the demand for ship electricity has increased significantly, and the performance requirements for ship power such as maneuverability, quietness and fuel economy have been significantly improved.
At the same time, with the increasing shortage of oil resources and worsening environmental pollution, countries are actively advocating the development of green ships and promoting the application of renewable energy in ship power.
Against this background, the ship integrated power system came into being and is hailed as the third revolution in ship power.
It not only realizes the integration of ship propulsion system and power system, but also makes it easier to achieve precise and efficient control of the energy of the entire ship and flexible access to various renewable energy sources, reducing the dependence of ship power on traditional fossil fuels.
The successful development of the new gas turbine will not only affect aircraft carriers, but also other fields such as ships, heavy industry, electricity, etc., and the technological achievements can be shared. Not only the military-industrial field, but also the economic field can obtain major development opportunities. It can be said that it kills two birds with one stone.
Wu Tong gained sufficient historical data and understanding of XCMG's divisions, and she began to settle down in the data room, deeply immersed in the research of the entire aircraft carrier's power system. Aircraft carriers involve a vast array of components, and even Wu Tong didn't intend to tackle every aspect at once. Her primary focus remained on her forte, the crucial power system.
"Leader Li, I plan to start with the power system. Firstly, this is my area of expertise, and secondly, this is also the reason why you invited me here!"
Although aero-engine dynamics and ship propulsion are almost entirely different, the fundamental knowledge of dynamics is universal. Although at first glance, the two appear to be worlds apart.
First, there are significant differences in their structures. Aircraft engines generally consist of an axial-flow compressor, a turbine combustion chamber, and a turbine driver.
Ship engines are mostly made of diesel engines, which generally use reciprocating internal combustion engines to drive mechanical equipment by pushing the crankshaft and connecting rod.
Due to their different operating environments, aircraft engines and marine engines have different performance specifications and requirements. Aircraft engines operate at high altitudes, in low temperatures, in thin air, and at high speeds, requiring large amounts of intake and compression air. Marine engines, on the other hand, are primarily used at sea and must withstand harsh environments such as seawater corrosion, high temperatures, and high pressures, requiring strong corrosion resistance and durability.
The main tasks of aircraft engines and ship engines are also different. Aircraft engines generally need to pursue indicators such as lightweight, high efficiency, and high power to meet the requirements of high-altitude and high-speed flight. Ship engines focus more on indicators such as stable power output, low fuel consumption, and low noise to ensure long-term navigation and economical use of fuel.
However, they still belong to the same engine category. After truly in-depth understanding and study, Wu Tong found that their relationship is complementary and many technologies of the two engines can be used interchangeably.
Even ship-mounted gas turbines were an improved version of the turbofan engine. Wu Tong's background in aerospace engines inevitably accelerated her learning of ship steam turbines and marine engines.
Wu Tong's arrival did not cause much commotion except for Engineer Xu who received him. After Wu Tong moved in, she basically stayed in the data room. The core data room was in the annex room under Engineer Xu's office. She traveled between the data room and her accommodation. Apart from Engineer Xu who granted Wu Tong the confidential data room access, almost no one else was aware of Wu Tong's existence.
It could be said that Wu Tong had minimized her presence in the 707 Institute. It was so low that if Xu Gong hadn't met with Wu Tong every day and helped her open the confidential information room, he would have hardly felt Wu Tong's presence at all.
Xu Gong was greatly impressed by Wu Tong's down-to-earth learning attitude. It was no wonder that Wu Tong could achieve so many world-shaking achievements at such a young age. Just by looking at her learning attitude, one could see the big picture from the small details and get a glimpse of the tip of the iceberg!
Over two weeks, Wu Tong had thoroughly reviewed the secret information in the data room. The aircraft carrier model she constructed in her deduction space became increasingly detailed and precise as the data was added, practically a one-to-one replica, accurate down to the last detail, down to the last component. She highlighted the powertrain, her primary research area.
This step, which also extended from the deductive space to Wu Tong's actual draft paper, was highlighted with color in the areas related to the power system. A detailed model, scaled down and assembled on a quarto sheet of white paper, once again impressed Xu Gong with Wu Tong's drawing skills and his ability to extract key points from the data.
