Chapter 257 Delivery(2/2)
In any case, it is impossible for superiors to respond negatively.
Therefore, after confirming the authenticity of the news and follow-up plan, Chen Nian immediately figured out what he wanted to do.
The so-called military observation is actually to put it bluntly, it is to dissuade conflicts.
Military observers will organize various patrols in conflict areas, monitor ceasefire lines and military demarcation lines, supervise the use of local weapons, investigate isolated incidents that violate ceasefire agreements, and disclose and report them.
The military observers sent by various countries are not very well armed. Their safety actually relies on the peacekeeping troops stationed locally, or further, on the country that sent the peacekeeping troops.
Therefore, in order to ensure that military observation can be carried out smoothly and safely, and to ensure that the purpose of military observation can be effectively achieved, there are two most important elements:
First, the national strength must reach the standard and have a decisive influence in the world.
This part limits the actions of the "official government". It can ensure that when the official government violates the ceasefire agreement and even poses a threat to local military observers, the country that sends the military observers has the ability to carry out actions on it, including but not limited to economic, policy,
Comprehensive diplomatic sanctions.
When necessary, the country can even be kicked out of the world game.
Considering this consequence, no sovereign government can arbitrarily harm the military observers of major powers, and even go to great lengths to ensure their safety.
There is no doubt that China has already been able to achieve this.
But the second one is relatively more difficult.
Because it requires strong military projection capabilities.
Or to put it another way, it is "equal ability to retaliate".
This part restricts the actions of "unofficial military organizations", which includes certain chaotic tribes in Africa and certain armed organizations in the Middle East that do not have legal rationality and have been forced into danger.
Those who are barefoot are not afraid of those who wear shoes. These organizations are often unwilling to cease fire, and they do not care to break up with the United Nations before they truly have influence.
If you want them to stop obediently, you can only show the sword and gun in your hand and let them know that if you want to play hard, they will not be able to survive it.
At this point, the current China is lacking.
——
Or actually, in the entire world, few countries can do it.
With a few fingers, only the three major forces of the United States, Russia, and Europe can basically guarantee this.
Therefore, what Chen Nian has to do is actually very simple, that is:
Come up with a piece of equipment as soon as possible that can greatly improve China's conventional delivery capabilities and form a global firepower deterrent.
To achieve this, there is no doubt that aircraft carriers and strategic bombers are the best choices.
After all, you can't just bomb others with ballistic missiles, but it's not difficult to pass a United Nations resolution for conventional bombing,,,,,,
Thinking of this, Chen Nian took a deep breath.
Now, his thinking is very clear.
Don't do any fancy operations, as long as the H-20 takes off, most of the problems will be solved!
He opened the latest information he obtained from Tang Changhong and began to read page by page.
All the problems recorded above are problems that have been encountered or are about to be encountered during the trial production of the H-20, including but not limited to the aircraft's hydraulic, power, airframe pneumatic and other modules.
At present, due to the introduction of carbon fiber production lines, the problem of body materials has been solved.
So the next step is to solve the flight control problem.
As we all know, for subsonic fixed-wing aircraft, the critical angle of attack is about 15 degrees. Below this angle, the greater the wing angle of attack, the higher the lift coefficient.
But after exceeding the critical angle of attack, the additional angle of attack will actually cause the lift coefficient to decrease!
The reason is very simple. When the average angle of attack of the front and rear edges of the wing exceeds the critical angle of attack, the surrounding airflow will separate from the fuselage and generate turbulent vortices, causing the fuselage to vibrate violently, and the aircraft will subsequently rotate inertially.
If during takeoff and landing, the wings may hit the ground, causing a flight accident; if at high altitude, the aircraft may roll, yaw or pitch deviations and other abnormal conditions, seriously threatening flight safety.
Due to the variable wing design used by the H-20, the risk caused by the critical angle of attack will be greater.
This part of the difficulty has troubled Tang Changhong for a long time. The solution they finally adopted was to use flight control software to precisely control the flight angle and limit the flight angle to avoid stalling.
But in Chen Nian's view, such a solution cannot be regarded as the optimal solution.
Even if the final flight control program can really achieve its intended purpose, it will still be a limitation on the overall performance of the H-20.
He already has a better, more effective, and more time-saving plan in his mind.
Plasma generator.
In his impression, the first active flight control plasma generating device in China was in 2013.
At that time, Nanjing University of Aeronautics and Astronautics launched the unmanned technology demonstrator Zidian. Through a series of wind tunnel tests, it was finally determined that whether it uses plasma open-loop control or pressure feedback control, the maximum lift coefficient of the test machine can be improved.
Above 27%, the stall angle of attack can also be delayed by more than 4°.
There is no doubt that this is a major improvement in the aerodynamic performance of the aircraft and is also the best solution to the critical runaway problem in the current technical environment.
The only difficulty is how to build the plasma device.
Nobody knows.
——
But Chen Nian knew.
He picked up the phone and dialed Tang Changhong's number.
After the call was connected, he immediately said:
"Mr. Tang, I read the report you just brought over."
"Yes, most of the problems are not difficult, but I also noticed that on some problems, your solutions are not appropriate enough."
"Mainly in terms of flight control."
"Yes, it's not possible to rely on software. The B-2's flight control program is advanced enough, but it will still fall when it should fall."
"I have a new idea, using a plasma shower to solve the airflow problem on the top of the machine."
"Yes, that's right, plasma generating device."
"Ah? Who will do it?"
"I'll come, I'll solve it!"
