Chapter 180: Meticulous
"Lu Xiao has always been efficient. As a technical person, we all hope for efficiency!" This is Hua Yanxing's heartfelt feeling. As long as people do research, there is no one who does not hope that the Great Wall project will be completed in one day. However, it is obviously a luxury.
Before Wu Tong emerged, the extraordinary research and development speed represented by Lu Xiao was already the top research and development speed in China, which made many people hesitate.
However, they now have Wu Tong, and Wu Tong's speed can already be used as a measurement term. Wu's state is the burst of Wu Tong's inspiration. Wu Tong's speed is the synonym for rapid research and development results.
"Wu Tong, the actual test data of fuel N24 is out. The highest specific impulse is 927, which is almost three or four times the best solid and liquid fuel before! The thrust performance is also very good, also exceeding the predicted data you gave!" She went to the site in person and followed the actual test, and got this shocking data first hand.
Several experts from the aerospace industry were so surprised that their eyes almost popped out of their heads. Before they came, they were a little skeptical about the predicted data of 800 starting points at the previous discussion meeting. They thought that if the actual test result was 60% off, it would be a new progress for China Airlines.
Unexpectedly, Wu Tong's data was just modest, and the actual value was even higher than predicted!
The data given by Wu Tong should be the lowest prediction, rather than the highest data that people usually use to demonstrate the effect.
High-energy explosives and high-energy fuels were born one after another, and the artillery leaders who were watching were dazzled by the good news for their missiles. The experts in the aerospace industry were full of excitement and were eager to develop solid-state engines.
However, there is still a problem that needs to be overcome before we can start solid research and development, but compared to this super fuel, that is nothing.
"The engine has too much to handle the high specific impulse, long duration and high temperature. The nozzle shows signs of softening over time, especially when it is fully loaded with propellant. It eventually melts completely. The situation is better when the fuel is halved!" Hua Yanxing said regretfully. This is inevitable.
The specific impulse of previous solid fuels was only two or three hundred, but now it has suddenly increased by more than three times. The same amount of fuel can last more than three times longer than before. It is inevitable that the materials of the old engines cannot withstand the impact of such super fuel.
It’s not the super fuel’s fault. They are still excited and surprised by the birth of such super fuel. However, reducing fuel configuration and improving the engine are issues that must be faced.
The same unit weight of fuel can have its burning time increased by more than three times, which means that their missiles and spacecraft can fly farther and faster.
Overcoming the small difficulties ahead is a task that we must strive for.
"I wonder if our new engine materials can withstand the high temperature of super fuel?" Hua Yanxing was a little worried. Although the materials they are using now are more advanced than the engine materials of the big guys who are about to be retired, there is a great possibility that they cannot withstand the burning of a full propellant column of super fuel.
After all, the new super fuel developed by Wu Tong can be said to be a groundbreaking advancement and may exceed the tolerance of current materials.
"Mr. Hua, I have thought about it. Let's see the test run results first, and then improve it!" When designing the engine, Wu Tong took into account the high inlet and outlet temperatures of the engine. The outlet temperature can even reach over 3000. Therefore, when designing, Wu Tong considered integrating the cooling system to reduce the pressure of excessive temperature on the engine and increase the energy efficiency ratio.
However, the data of the accidentally derived fuel N24 was indeed beyond her initial expectations after she further refined the numerical proportions. Fortunately, she had reserved some space and could give it a try.
Wu Tong briefly told Hua Yanxing about her ideas and directions for improvement. After completing the projectile optimization, she planned to do the optimization derivation of new materials for the combustion chamber nozzle and the two-way derivation of the coating.
There are also new materials for the missile body... everything needs to be done one by one, and it is impossible to arrange them all at once. She regrets that she does not have an extra pair of hands and the ability to do all the work.
After all, the technology of solid rocket engines is simple. After the 1960s, the technology of solid rocket engines has made progress, and now many missile launches use solid fuel engines.
The catapult engine is not compatible with the new fuel. If it is compensated with a high-temperature resistant coating, minor improvements can be made on the basis of the existing missiles in service, and the new fuel can be used as soon as possible to increase endurance and combat effectiveness. This is the fastest way to improve it.
The reform of various missile engines cannot be accomplished in a short period of time. Moreover, it is unrealistic to immediately retire the missiles that have been manufactured and put into service. If a super high-temperature resistant coating can be developed, it can further save the country's losses, and high-temperature resistant coatings have many uses.
The new material is a complement to the new engine she designed, and the coating is for existing spacecraft and missiles that want to switch to fuel N24. It would also be good news if someone could develop and manufacture it before her.
After all, her energy is limited, and she cannot focus on all scientific research areas. If China's scientific research community can flourish, Chinese science and technology will be able to take big strides forward.
Hua Yanxing nodded seriously. Wu Tong's consideration was very thorough. He had become increasingly proficient in the responsibilities and powers of the project chief designer, and she hardly needed to supplement him. His research and development was even more advanced. He was indeed an excellent talent. He performed well in all areas and improved very quickly.
However, regarding the research and development of new materials, Hua Yanxing feels that it still depends on Wu Tong's estimation. Other teams are not as efficient as Wu Tong.
After discussing a question, Wu Tong asked Hua Yanxing about the details of missiles. As an older generation missile expert who has been working in this field for 20 to 30 years, she has a lot of experience that she can learn from. The more she understands and masters it, the more she can ensure that PL-15 is foolproof.
Taking on such an important national scientific research project for the first time, Wu Tong was not afraid of treading on thin ice, but was extremely conscientious in his actions.
In the missile body design section, the structure, aerodynamics, ballistics, the working requirements of each system on the missile, the tactical indicators of the missile, the longitudinal configuration of the wing surface along the missile body... must all be taken into consideration. It is never too detailed to go through it bit by bit.
Any negligence in details may lead to failure, which will bring a blow to the entire project and waste national resources. The cost of scientific research has always been realistic and cruel, and the cost of failure is too high!
