Shenhao starts from seeing through scratch-off games

Chapter 708 Failure is not terrible

Following Tao Peng's order, everyone's eyes never left the plane.

Because in the aerospace industry, everyone knows that there is a saying circulating in the international aviation community: "Inventing an airplane is nothing, building an airplane is nothing, but testing it is extremely difficult."

However, after such a long period of troubles, and with everyone's common expectations, the aircraft finally began its test flight.

Li Xiyan is the most nervous in her heart. Although she is not a shareholder of the Xia Fei Group and does not hold any shares, she is more concerned about Wang Yu's success or failure than anyone else present. She has been pinching Wang Yu beside her. Wang Yu's arms were squeezed tighter and tighter, until Wang Yu was squeezed until he turned red.

Wang Yu turned around and asked, "What are you doing?"

Only then did Li Xiyan react, let go of Wang Yu's arm and said, "I'm worried about you. What will happen if this experiment fails?"

Wang Yu had already used the system to see that it would not fail, but he could not say that. Instead, he replied calmly: "If it fails, then it will fail. 1000 million is not money to me! The worst is that it will happen later." Keep studying, it’s not like you’ll quit after failing once!”

This was heard by the people next to him, and they couldn't help but sweat for Wang Yu.

The main thing was that the faces of Xu Xiaoma, Bao Yinfeng and others scared Li Xiyan.

They are all practitioners in the aerospace industry. They have rich experience and know very well about engine development. Although their technology is not good, they know how difficult and important it is to test the appearance of the engine and the test flight of the aircraft.

"Tao Peng, I think you, the new big boss, are going to lead you into a trap!" Xu Xiaoma said to Tao Peng.

Tao Peng didn't manage money at all and just glanced at Xu Xiaoma.

"An engine can be built in 10 days, and it still needs to be tested. Based on your research and development time and economic costs, the speed of this company's bankruptcy will only become faster and faster!"

Generally speaking, the birth of an aircraft must go through four stages: demonstration, design, trial production and test flight. Test flight has the longest period, the most requirements, and the highest risk among all links, requiring designers, test pilots, and maintenance personnel. participate.

For early fighter aircraft, the flight test process was relatively simple and often consisted of designers, test pilots, and flight test engineers. This is no longer the past era. The pilot did not need to go to the toilet in person on the aircraft. The first step was to bring the aircraft to the sky with the unmanned driving system. , if this process is successful, letting the pilots go up for a test flight will greatly reduce the risk.

The structure of modern fighter aircraft is complex, including dozens of subsystems and tens of thousands of parts. In order to integrate such complex and huge systems and parts while ensuring safety and reliability, test flight requirements and difficulties are far greater than in the past.

The flight test process of modern fighter aircraft usually starts with the flight test engineer determining the flight test qualification plan. After approval by the relevant aviation agency, the flight test engineer then forms a flight test outline based on the qualification plan and assigns the flight test tasks to the research team for implementation.

In accordance with the requirements of the flight test outline, the engineers of the research team further refined it and formed a specific task list of which subjects need to be tested and which parameters need to be obtained for each sortie. Finally, all subjects must be tested one by one by test pilots according to the task list. After the first demonstrator is produced, it cannot be tested immediately. It must first conduct an in-loop test on the ground. That is to apply hydraulic pressure to the demonstrator and power on the demonstrator. The pilot will fly the fighter plane to simulate flight conditions. In this way, the various functions of the demonstrator can be tested. index.

These processes are complicated to hear, but for Wang Yu, Xia Fei and trusteeship, they are all eliminated, because with the help of system identification, these uncertain factors have been overcome in the research and development stage.

After the first flight, the fighter aircraft will have to undergo two stages: adjustment test flight and finalization test flight before it can be officially commissioned into the army.

Adjustment of test flights is to discover and improve various design and trial production problems of fighter aircraft, which is equivalent to a "bottom test."

Generally speaking, errors and omissions will inevitably occur during the trial production of fighter aircraft. For example, if a qualified product is installed on a new machine, it may not work properly; the maintenance personnel do not have sufficient knowledge of the new machine and may occasionally make operational errors. These uncertain factors will cause differences between the data calculated before the test flight and the actual flight data. Adjusting the test flight can focus on solving the design and manufacturing problems of the fighter aircraft and keep the fighter aircraft in a relatively stable test flight state.

After the adjustment test flight, the fighter aircraft will enter the final test flight, which is the "graduation examination" of the fighter aircraft. At this stage, a comprehensive physical examination will be conducted on the finalized fighter aircraft to determine whether the fighter aircraft meets technical specifications and usage requirements.

In the process of fighter aircraft test flight, the final test flight has the greatest risk, takes the longest time, and has the most subjects. Especially for newly developed fighter aircraft, at this stage, comprehensive testing must be carried out from basic flight performance to edge subjects, from avionics systems to airborne weapons.

Now the plane took off very smoothly, without any abnormalities in the air, and landed perfectly on the ground 20 minutes later, intact.

The spectators were all stunned because it was so unexpected.

Wang Youzhi, Xu Xiaoma, Bao Yinfeng and others couldn't believe their eyes, their hearts were trembling at the moment.

Xu Xiaoma was thinking, if this engine is really at the internationally advanced level, many generations ahead of other countries, then the future development space of Xia Fei Group cannot be imagined. It will definitely make rapid progress like Xi Yanwei, surpassing other aerospace companies. Rub it under your feet.

But now that he thinks about this problem, there is no point in thinking about it. The shares have been withdrawn, and he can only think in another direction, that is, this engine only looks smooth and stable, but problems will occur in the actual combat process in the future, such as Battery life issues, wear and tear issues, emergency response issues, etc. Now his previous bet with Wang Youzhi was not to care about these. Whoever wins won't care about Xu Xiaoma's affairs. He stood aside and watched.

But Wang Youzhi couldn't give up 1000 million to Wang Yu so easily. He continued to find faults and make excuses. Anyway, he was dissatisfied with all kinds of things: "The driverless one is good, but will there be any problems if there are people driving? Do you dare to find a pilot to try?"
