Chapter 253 Vertical
Wu Tong would never force himself to do something he is not good at.
She learned from her teachers, whether it was Dean Pan, Teacher Zhou, Teacher Cheng Huanan, or Mr. Hua from Hua Yanxing, with whom she had worked together... These were elders who had high hopes for her. Every time she met them, they enjoyed it and were willing to give their all and pass on their experience to Wu Tong.
The basis of management is that she does not have to take control of everything in her own hands. What she should do is to control the overall situation. The details will naturally be left to more professional people to perfect. She only needs to convey the state she wants to achieve and accept the results.
Finding land and building a house require a lot of money. Wu Tong feels that she should hurry up and produce some results and seek financial support from above. This is what she should do.
She has enough value, and the higher-ups will naturally solve the problems she wants to achieve.
Although she felt embarrassed to trouble the higher-ups, Wu Tong felt that seeking help from them was the most appropriate way rather than putting herself in a difficult position with things she was not good at. She would repay the country with what she was good at.
In addition, in the second half of the year or by the end of the year, her Zhongyuan Group's dividends will be received. If the amount is considerable, it can also be used as start-up capital investment, instead of relying entirely on support from above and adding too much trouble to them.
After determining the focus of his work, Wu Tong continued to devote himself to new research.
The NS equation had just made some small breakthroughs, but it had reached its limit and could not move forward for the time being. Wu Tong did not insist on specializing in research, but turned to another topic, carbon fiber composite materials.
Carbon fiber composite materials are inorganic high-performance fibers that are transformed from organic fibers through a series of heat treatments and have a carbon content of more than 90%. They are a new material with excellent mechanical properties. They have the inherent characteristics of carbon materials and the softness and processability of textile fibers. They are a new generation of reinforcing fibers.
Its advantages are obvious: low specific gravity, less than a quarter of that of steel, and high strength. The tensile strength of carbon fiber resin composite materials is generally above 3500Mpa, which is 7 to 9 times that of steel, and the tensile elastic modulus is 23000~43000Mpa, which is also higher than steel.
Therefore, the specific strength of CFRP, that is, the ratio of the strength of the material to its density, can reach more than 2000Mpa/(g/cm3), while the specific strength of A3 steel is only about 59Mpa, and its specific modulus is also higher than that of steel.
It has become an advanced aerospace material due to its low specific gravity, good rigidity and high strength.
Because every 1 kg reduction in the weight of the spacecraft can reduce the weight of the launch vehicle by 500 kg. The same principle can be applied to fighter jets. Every reduction in the weight of a fighter jet means an increase in its payload and maneuverability.
Weight reduction has always been an eternal research topic that the aerospace industry has been pursuing.
Therefore, in the aerospace industry, carbon fiber composite materials have been constantly pursued, and the use of advanced composite materials has always been an urgent need for aerospace.
Most importantly, if they can achieve a breakthrough in carbon fiber composite materials, they will be able to realize the possibility of vertical take-off and landing fighter jets.
A vertical take-off and landing fighter is a fighter jet that uses vertical take-off and landing technology to take off and land.
Vertical take-off and landing fighters can take off and land without taxiing, have low requirements for runway conditions, can follow ground force deployment and attack on the front line and attack ships, respond quickly to front support, and are very flexible to use.
There has not been any typical breakthrough in this area in China, but with international development, this is a difficult problem that must be overcome.
As the country moves towards the deep blue, in order to better defend the motherland and protect our territorial waters and airspace, it is imperative to master the technology of vertical/short take-off and landing aircraft.
This is also the type of aircraft favored by the navy/military, because the length of the flight deck on a ship is always limited, and vertical/short take-off and landing technology is particularly practical.
She and Professor Lu Xiaolu had a detailed discussion on the development direction of the J-35. "The J-20 has reached a certain upper limit of the current technical level. Yes, they can continue to overcome technical difficulties, break through the upper limit, and design and develop a fighter jet that can fly faster and farther."
"But the long-range, fast and powerful payload of the J-20 are too similar to those of the J-20. This will mean that the J-20, which has world-class performance, will not have many years of service before it faces the possibility of retirement. Too much overlap in performance is also a waste of resources."
The J-20 has entered full production and is rapidly arming the country's southeast, northwest and north to guard the country's front. Currently, the southeast coast and northwest border have been equipped with J-20 in service.
The super-superior performance of the J-20, as well as its powerful combat radius and super endurance, ensure that they can directly surround the southeast and northwest directions.
Therefore, in the end, she and Lu Xiao agreed on the same direction, which was to define the J-35 as a carrier-based aircraft. The best scenario was to achieve vertical take-off and landing, the possibility of electromagnetic catapult, and to make further breakthroughs based on the J-20 Vily.
With the authority of Wu Tong and Lu Xiao, they were able to track down and learn some confidential information that had not yet been made public. China's first aircraft carrier, the 001, had been basically completed and would be delivered to the Chinese Navy for sea trials in the near future. It would then enter service and become a powerful weapon for China.
China will have its own aircraft carrier.
Such exciting good news, as the Chinese people, filled their hearts with excitement and made them eager to do something for this great mountain-guarding weapon, for example, to make it more deterrent.
Aircraft carriers have become an indispensable weapon for modern navies and a symbol of a country's comprehensive national strength. They have great attack power, good maneuverability, seaworthiness, wave resistance, and strong protection capabilities. They usually form aircraft carrier battle groups with escort ships such as cruisers, destroyers, frigates, submarines and supply ships to perform combat missions.
The other ships in the fleet provide carrier protection and supplies, while the carrier provides air cover and long-range strike capability.
Aircraft carrier fleets, with aircraft carriers at the center, are one of the most important ships in naval warfare. Relying on aircraft carriers, a country can have the ability to conduct long-range operations in areas far away from its homeland without relying on local airports.
Therefore, the air strike capability of an aircraft carrier is a crucial link, and the demand for vertical take-off and landing fighters is imminent.
Vertical take-off and landing requires extremely high performance from the fighter plane itself. To achieve such high performance, the material difficulty lies in the carbon fiber composite material technology that is currently being developed and widely used in the world's advanced fighter planes. This is the top priority that must be overcome!
Only by overcoming the material difficulties can we continue to achieve the next R&D implementation plan!
