Before returning to the college entrance examination, I became popular in the science circle

Chapter 254 Vertical
Wu Tong has never forced things on himself that he is not good at.

Learning experience from teachers, whether it is Pan Yuan, Teacher Zhou, teacher Cheng Huanan, and Mr. Hua Yanxing, whom she has worked with... these are all elders who have high hopes for her. Every time they come into contact, she never tires of it. They are willing to give everything they have to pass on their experience to Wu Tong.

The basis of management is that she does not need to take everything into her own hands. It is her job to control the overall situation. The details are naturally left to more professional talents to complete. She only needs to convey the status she wants to achieve and accept the results. That’s it.

Finding land and building a house requires a large amount of funds. Wu Tong feels that she should hurry up and make results and seek financial assistance from above, which is what she should do.

She has enough value, and the higher authorities will naturally solve it for her. Whatever she wants to achieve,

Although she was embarrassed to bother her superiors, rather than embarrass herself by being trapped in something she was not good at, Wu Tong felt that it was the most appropriate way to seek help from the superiors. 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 dividends will be recorded. If the amount is considerable, she can also invest in start-up capital. She will not rely entirely on all the support from the above, which will add too much trouble to the above.

After determining the focus of his work, Wu Tong continued to invest in new research.

The NS-equation has just made some small breakthroughs, and it has reached its upper limit and cannot 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 material is an inorganic high-performance fiber with a carbon content of more than 90%, which is transformed from organic fibers through a series of heat treatments. It is a new material with excellent mechanical properties. It has the inherent characteristics of carbon materials and has the characteristics of textile fibers. Excellent soft processability, it is a new generation of reinforcing fiber.

Its advantages are obvious. It has a small specific gravity, less than a quarter 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. The tensile elastic modulus is 23000~ 43000Mpa 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 small specific gravity, good rigidity and high strength.

Because for every 1 kilogram reduction in the weight of the spacecraft, the launch vehicle can be reduced by 500 kilograms.The same principle can be applied to fighter jets.Every time a fighter plane reduces its own weight, it means that its bomb load and maneuverability increase.

Weight reduction has always been an eternal research topic that is constantly pursued by aerospace industry.

Therefore, in the aerospace industry, carbon fiber composite materials have been continuously pursued, and the use of advanced composite materials has always been an urgent need for aerospace.

The most important thing is that 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 that takes off and lands using vertical take-off and landing technology.

Vertical take-off and landing fighters can take off and land without taxiing. They have low requirements for runway conditions. They can deploy and attack ground forces on the front and on attack ships. They respond quickly to forward support and are very flexible in use.

There is no typical breakthrough in this area in China, but with international development, this is a difficult problem that must be overcome.As the country moves into the deep blue, in order to better defend the motherland and protect our territorial waters and airspace, technical breakthroughs in vertical/STOL aircraft are a must.

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 Teacher Lu Xiaolu had a detailed discussion on the development direction of the J-35. "The Veyron J-20 has reached a certain upper limit of the current technical level. However, 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 just the distance and speed, coupled with the powerful bomb load, these contents still overlap too much with the Veyron J-20. This will also make the J-20, which leads the world in super-class performance, not have many years of service. Facing the possibility of decommissioning, overlapping performance is also a waste of resources."

Veyron has entered full production and is rapidly arming the country's southeast, northwest and guarding the country's front.Currently, the coast of the Southeast China Sea and the northwest border are equipped with Veyron J-20s in service.

The super superior performance of the Veyron J-20, as well as its powerful combat radius and super endurance capability, ensure that they can directly surround the enemy with a radius and take care of 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 idea was to realize vertical take-off and landing, and the possibility of electromagnetic ejection, also on the basis of the J-20 Veyron. Make breakthroughs.

With Wu Tong and Lu Xiao's authority, they can basically follow up on some confidential information that has not yet been made public.China's first aircraft carrier No. 001 has been basically completed. It will be delivered to the Chinese Navy in the near future and will enter the sea trial. It will then enter the service sequence and become a powerful weapon for the great power in China.

China will have its own aircraft carrier.

Such exciting good news made them, as Chinese people, so excited that they eagerly wanted to do something for this great mountain-suppressing weapon, for example, to make it more intimidating.

Aircraft carriers have become an indispensable weapon for the modern navy and have become a symbol of a country's comprehensive national strength. They have great attack power, good maneuverability, seaworthiness, seakeeping, and strong protection capabilities. They are usually combined with cruisers, destroyers, frigates, Escort ships such as submarines and supply ships form an aircraft carrier battle group to perform combat missions.

Other ships in the fleet provide carrier protection and supplies, while the carrier provides air cover and long-range strike capabilities.

The aircraft carrier group, with the aircraft carrier as the center, is one of the most important ships in naval warfare.Relying on aircraft carriers can enable countries to conduct long-range operations in areas far away from the country without relying on local airports.

Therefore, the air strike capability of the aircraft carrier is a crucial part, and the need for vertical take-off and landing fighters is urgent.

Vertical take-off and landing requires extremely high performance for the fighter aircraft itself. To achieve such high performance, there are material difficulties. That is, the carbon fiber composite material technology that is currently being developed and widely used in the world's advanced fighter aircraft must break through the key points. Top priority!

Only by breaking through the material difficulties can we continue to achieve the next step of R&D implementation plan!
