Lu Xiaopeng: "Besides, it only has one engine. A single-engine reconnaissance plane dares to go deep into the territory of China and the Soviet Union for strategic reconnaissance. The Americans really dare to do it."

Several aviation experts from Chengfei and Shenfei conducted analysis and research on the engine, and concluded that the J75 is not black technology, at most it may be more reliable.So, where is the black technology of U-2 flying 24000 meters?

Tang Hua: "Lao Lu, you also have a research project on ultra-high-altitude aircraft, so you not only need to study its engine, but also look at the overall design of this aircraft, especially the aerodynamic layout of the fuselage. The secret of this aircraft may be on the fuselage."

……

Lu Xiaopeng and several general aviation designers left the J75 engine and went to the center of the hangar to look at the U-2 fuselage.

"Comrade Rurika Mefudi, the two small jet engines designed by the Central Aviation Engine Research Institute are very good," Tang Hua said to Mefudi, a Soviet expert who came to Beijing from Moscow to study U-2. Fuel consumption has exceeded my expectations."

Mefoji: "That's our specialty... But if the performance exceeds expectations, why then propose to start developing the next generation of small turbofans?"

The Moscow Central Aviation Engine Research Institute spent three years researching small turbojet engines. In this era, for small turbojet engines, the three-year development cycle is relatively long.

但是小型涡喷的效果是立竿见影的：用A型小涡喷替换原先的固体火箭发动机后，鹰击-2反舰导弹的飞行速度从0.85马赫略降低到0.8马赫，射程从42公里增加到85公里，这导弹现在叫做鹰击-3。

The YJ-4 anti-ship missile and the Changjian-2 cruise missile are two close relatives, one anti-ship and one land attack, this missile is 2% larger than the YJ-3/50, but the range is 300 kilometers, in this era , It has exceeded the understanding of the concept of "tactical missiles" by naval and air force generals in many countries.

"The range of cruise missiles using B-type turbojet is 300 kilometers," Tang Hua said. It is much more convenient to use this kind of missile.”

Mefoji: "It seems that you said last time, the concept of stand-off launch. But the P-5 missile is also stand-off launch. P-5 can also fly supersonic."

Tang Hua: "But on an airplane or a warship, the space for one P-5 can almost hold six Longsword-6..."

Next to the U-2 fuselage.

"The materials used in the fuselage structure are so thin." "The load-bearing structural frame of the wing is also very thin. The Americans have reduced the structural margin of the aircraft to the lowest level."

"The cockpit is also very narrow..."

Lu Xiaopeng and others observed U-2 and drew many conclusions.

"The U-2 uses a large straight wing, which is how the Americans solve the problem of flight instability," Huang Zhiqian said. "Its vertical tail is very high and has a large area, and there are two long cylinders on the left and right sides of the wing. These are all designed to increase its stability in level flight. Coupled with the responsive steering control system."

Lu Xiaopeng: "I want the industry department to analyze the U-2's fuselage structure materials. If we can manufacture this kind of material, then Chengfei can also produce this kind of aircraft."

……

"Old Li, did you find anything?"

Tang Hua and Li Qiang were next to the wreckage of U-2. Tang Hua stretched out his right index finger and rubbed the paint covering the outer skin of U-2.

Li Qiang: "I just discovered that the paint on the outside of this plane has its own way."

"It's very thick, much thicker than the paint on the surface of ordinary aircraft. You know, this is an aircraft that has very strict requirements for weight reduction, but it is painted with such a thick layer of paint. Looking at the material of the paint, it is obvious that there are Composition of iron oxide."

Tang Hua found the edge of a skin fragment. The black paint on the surface was not only very thick, but also had a very different formula.

Li Qiang: "Minister Tang, it seems that you guessed right a few months ago. A stealth coating made of iron oxide."

When the radar detected U-2, the effective detection range dropped sharply. This not only aroused the interest of the Air Force and the Aviation Industry Bureau, but also attracted the attention of several radar institutes of the Electronic Information Industry Bureau.Tang Hua put forward a hypothesis at the end of last year: the surface of this American aircraft may be coated with a layer of iron oxide. Radar waves shining on the aircraft can penetrate the coating, but will be detected by the The iron oxide composition is severely attenuated.Once the radar wave enters and exits, the energy attenuation rate in the coating is relatively considerable.

Li Qiang: "Iron oxide powder is mixed into the paint on the skin of the fuselage and spread evenly. If all the exposed surfaces of the whole aircraft have stealth coatings, then our aircraft can also have a certain deception effect on radar."

"Wait a minute, wait a minute," Tang Hua pulled back to Li Qiang's thoughts, "How to design our own stealth aircraft is the work of those people over there. We have to consider whether the radar we made can make this iron oxide stealth paint The layer goes back to having no effect."

Li Qiang:?

Tang Hua: "Iron oxide has a maximum absorption peak for radar waves in a certain band, but when it shines on radar waves that are not within this optimal band range, its energy-absorbing effect is not so strong."

Li Qiang: "So, we should test, which band of radar absorption effect is the best and which band is the worst for a coating of this thickness made of iron oxide as the substrate?"

Tang Hua: "Yes. I'm afraid we have to copy the formula of this paint, and then paint it on some kind of aircraft of our own to do a few tests. In addition, in addition to iron oxide, there are aluminum oxide or ceramic particles, Titanium oxide...we may have to try these formulations."

Zhongnanhai.

"This visit to Myanmar basically got what we wanted, and the airspace passed a secret agreement. When China needed it, Myanmar opened up the airspace in northern and northwestern Myanmar to us. Well, in fact, it is their air defense radar network like a sieve. , In fact, we don’t say hello to them, and they may not be able to find out when planes from Baoshan and Lijiang cross the border and fly across the border to eastern India.”

Boss Peng returned from Myanmar to report on the results of the visit.

Chairman: "If you don't say hello, you will sneak into Myanmar's airspace. In the future, you will be passive in diplomacy. We will not give other countries such excuses. For this reason, signing an agreement with Myanmar and exchanging some conditions will be beneficial to future diplomatic work." beneficial."

Mr. Peng: "The terms of exchange were discussed by Mr. Xiang. I didn't talk much. However, as soon as Wu Nu opened his mouth, he asked China to help him with a few sets of air defense missiles. Heh, the imagination is too rich. Things like air defense missiles, Will they play?"

"So we still have to draw a bottom line. When they ask for something, we will counter the price with him," the Prime Minister said. "The normal state of diplomatic negotiations. We don't give the most advanced models of anti-aircraft missiles, but some old models We can provide it to the outside world, but the benefits that Myanmar is giving us now cannot be exchanged for anti-aircraft missiles."

Kuala Lumpur.

Since he could no longer be a hermaphrodite, Herter could only discuss the matter with Boss Chen and find a way to eliminate the current tense situation between China and the United States.

Since 1949, the enmity accumulated between China and the United States seems to be... pretty big.The first is to resist US aggression and aid Korea. China sacrificed nearly 10 volunteers. Of course, the United States was not much better, with more than 7 killed.

Then there was the Battle of Taiwan, which was considered a campaign initiated by China. Apart from anything else, it hammered the US fleet cruising in the Taiwan Strait, and the US military advisory group in Taiwan also suffered casualties.

But these two things are impossible to negotiate terms openly.

The Chinese People's Volunteers were dispatched to resist US aggression and aid Korea.During the Taiwan campaign, American warships were indeed patrolling the Taiwan Strait, the hinterland of China. In the debate, Boss Chen definitely had a hundred reasons to say that your fleet must be destroyed.

What the United States can say is that China nominally inherited the Republic of China under President Li Dai, and the Republic of China has borrowed more than 10 billion U.S. dollars from the United States over the years, and your People’s Republic of China will inherit it.During the period of the Republic of China, the United States still had some assets in China that were confiscated and returned to the country, so we have to give an explanation.

"A good business reputation is a necessary prerequisite for the normalization of relations between China and the United States." Herter talked about business, and he began to talk endlessly. "After all, it is a loan document signed by Chang Kaishen and Finance Minister Song Ziwen. This loan The negotiation was completed by Ambassador Gu Weijun, what a coincidence, Mr. Gu Weijun is also in Washington now, performing the duties of the Chinese ambassador to the United States, am I right?"

Boss Chen: "It is not difficult to borrow and repay. This is a simple truth, but borrowing money must also be borrowed in a proper way."

Herter: "You're digressing. As long as the procedure of the loan contract is legal, it is a commercial loan contract that needs to be followed."

Boss Chen: "I haven't finished talking yet. What is borrowing in good faith? Firstly, you can't sign a loan contract by means of coercion and fraud, which is called forced borrowing; Obviously there is a contract that violates justice. The United States lent Chang Kaishen 10 billion U.S. dollars, and Chang Kaishen turned around and used the money to fight a civil war, causing huge casualties and sufferings to the Chinese people and great losses to the country. Is it against justice?"

Herter: "This is Chang Kaishen's personal problem. It was clearly stated in the 1948 Sino-US loan contract that this loan was used to save China's economy, restore China's transportation, communications, industry, and purchase food, fertilizers and other materials. Improve people’s livelihood. The United States is not responsible for the use of Chang Kaishen’s livelihood loans for military use. The U.S. government is only responsible for the affairs of the United States.”

Boss Chen: "I have something to ask you about what you are doing in your own country."

Herter: "?"

"In 1955, the American Radio Corporation imitated the Chinese DJ-1 walkie-talkie without permission, infringing on 7 technical patents held by my country. These patents have been registered in Europe and the United States; , imitating China's T1956 computer and transistors, infringing 51 technical patents and design patents; Illegal imitation of computer monitors in China is in the process of litigation. Also, in 19, artists under Shengli Records illegally sang two Chinese songs without authorization..."

Chapter 221, Kuala Lumpur Marathon

When the film of the first return capsule of Tianyan-[-] was developed, the second return capsule also landed successfully.

Tianyan-6 has 160 independent return film compartments, each compartment can hold a maximum of 80 films, but the first star is loaded with [-] films.Since its lens is specially designed, it is only suitable for taking panoramic photos of the earth at the apogee, so during this period of time it takes it easy and takes pictures of the world scenery roll by roll.

The shooting point of the second return capsule is over China, and the shooting point of the third return capsule is over Europe.The films of the three return capsules were used for magazine covers and newspaper front pages in the Soviet Union, China, and East Germany respectively.
