Morris put the lid on the teacup gracefully: "There are still some deals that can only be decided by you and me. Bristol-Olympus engine, is your country interested?"
Mr. Chen: "I remember our first cooperation was the parts and drawings of Olympus engines."
Morris: "Three years have passed, Rolls-Royce has upgraded the engine, and now it is not the original Bristol BOl.1, but Bristol BOl.12, or Olympus MK 102."
Mr. Chen did not answer for the time being. He needs to go back to his superiors by telegram for such a temporary trade question, and then wait for the superiors' instructions.
Morris lowered his voice: "It is definitely the original authentic product for the British Air Force's own use, and the quality is guaranteed. It was produced for the Avro Vulcan bomber, but the British government cut the defense budget, and the production of the Vulcan bomber was cut, so there are a batch of engines remaining .This is a rare opportunity, if you miss it, you will never be able to buy it again."
Mr. Chen: "I will ask my superiors for instructions on this matter. We will make an appointment for tea in two days."
"Of course, it's reasonable." Morris handed several pages of engine description documents to Mr. Chen, "I'll see you the day after tomorrow."
……
The telegram was sent back to Guangzhou from Hong Kong, and was immediately forwarded to Beijing.After reading the telegram, the Ministry of Foreign Trade immediately forwarded it to Tang Hua and Liu Nai.
"Chengdu Institute has done a good job in the past two years, and the Bristol-Olympus engine has been imitated," Liu Nai said, "but the performance is a little bit unsatisfactory, and the overhaul cycle... no, the life span is only 100. Hours later, the main reason they also found out was that a rotating part was poorly designed and worn out too quickly, and to replace this part required a complete dismantling of the engine."
Tang Hua: "When we asked for this thing in 1953, only the first-generation model of this engine was produced in the UK. In fact, the engine and blueprints from the British were used for training in Chengdu. The equipment was run together, the engine was produced according to the drawings, and the reason for the short life was found, which is beyond my expectations.”
Liu Nai: "Then shall we buy these engines or wait for the Chengdu Institute to solve the current engine wear problem?"
Tang Hua: "I suggest eating it and buying blueprints from the British. It doesn't matter if you don't sell it, we survey and map imitations. The thing we bought in 1953 is indeed a relatively original model, and now the British sell good products."
The Olympus MK 102 is a 5-ton engine, and each Vulcan bomber is equipped with 4 engines. The design thrust of the engine blueprint bought in 1953 was only 4.1 tons, and the short-life problem was encountered by the British themselves, and it was overcome in subsequent improvements.
The magnitude of the Vulcan bomber is basically the same as that of the Tu-16. The Vulcan has four engines and four Olympus engines with a thrust of 4 tons; the Tu-5 has two engines and two 16-ton engines.
China has decided to introduce the Tu-16. Of course, the Aviation Industry Bureau will not use the MK102 to build a bomber, which will repeat the construction.
In addition, there is another thing. Tang Hua knows the truth, but he doesn't intend to reveal it:
The British government did not reduce the production of Vulcan bombers. Now that the Cold War is at its climax, the UK would not dare to reduce the production of bombers even if it cut down its aircraft carrier.After the first batch of 101 Vulcans equipped with Olympus MK15 were produced, the second batch of Vulcans were installed with Olympus MK102. The number of orders was 45, and all 45 were delivered in full.
So this is purely Bristol-Rolls-Royce trying to make another buck.

Chengdu Aviation Consortium—Chengdu Engine Manufacturing Plant.
"Director Lu, the British have agreed to sell us a new version of the engine!" Tu Jida rushed into the design center, "The Ministry of Foreign Trade has approved it, and we can get the engine in a few months!"
"Rolls-Royce's MK102, right?" Lu Xiaopeng said, "I went to Rolls-Royce to communicate with Rolls-Royce when I was working at Gloucester Aircraft Company, but unfortunately that was 10 years ago. Since there are a batch of ready-made engines , then our plane can start.”
Tu Jida: "Yes, that...enlarged version of JJ-1."
Lu Xiaopeng: "An enlarged version of the JJ-1, even the shape of the wing has been changed. It is a completely new aircraft. This is a replacement for the Il-28."
Tu Jida: "But it doesn't look like a bomber. Director Lu, the Il-28 is relatively advanced in the world right now, and it won't be considered backward after 10 years. We're starting to develop its replacement right now?"
Lu Xiaopeng: "What does this mean? It means Minister Tang gave us 10 years to develop it."
The test flight of Chengfei's JJ-1 second version was particularly smooth. The test flight ended in December 1955, and it was finalized in January 12. Now it has been mass-produced.
The second version is mainly to modify the air intake, adopt a newly designed cockpit, and install a 1mm cannon.
After September 1955, the test pilots used the 9mm cannon to "da da da" on the shooting range, and also tried to drop the training bomb of the penetrating bomb at low altitude - the auxiliary fuel tank hanger on the abdomen of JJ-23 could also hang bombs.
No matter how you look at it, JJ-1 looks a bit like the F-80 "oil picker", with straight wings, not too fast (compared with MiG-15), and can drop bombs.Of course, its main function is to train pilots.
The newly designed aircraft has not yet been named, and Lu Xiaopeng does not know whether the aircraft starts with "Boom" or "Strong".The air intake layout on both sides of the twin engines, two Bristol/Olympus series engines, the total thrust is 10 tons, and the maximum take-off weight is 25 tons.
下发的规划书里面明写了：不设内弹仓，要求每侧机翼下3个挂架，机腹1个挂架最多可以挂载4枚鹰击系列空舰导弹和1个副油箱，或是2枚鹰击和3个副油箱。
As for the small pylon on the outermost side, in the planning book given now, it is for hanging air-to-air missiles...
When Tu Jida heard the word "10 years", he said unconvinced: "If we really didn't develop this kind of aircraft 10 years ago, we would be too sorry for the country. It should be at least two or three years in advance, at least... one year in advance." Two years?"
"Jianjiao-1 weighs only 8 tons, and this aircraft suddenly reached 25 tons. How can it be so easy to make it?" Lu Xiaopeng said.
"You assisted in the development of anti-aircraft missiles in 50 and 51. Didn't they just come out in a few months?"
"That's a missile, not an airplane, and Minister Tang is personally involved in the design."
……
For Cheng Fei, Tang Hua has set a strategic development route for them since 53:
If you wave hard, you can wave for ten years.
Of course, small work such as opening up the second MiG-17/21 assembly line must be done; mass production of simple aircraft such as JJ-1 is also possible.
However, within 10 years, Chengfei can only produce these two kinds of entities, and then the R&D department can keep brainstorming.
But Chengdu's engine and aircraft research and development departments can open up their brains and make bold designs.For example, in this battle bombing, it is required to be able to attack with missiles, to install a large radar on the nose, and to have a range, but nothing else, so that Lu Xiaopeng and Tu Kida can play freely.
Not only the aircraft design, after the MK102 engine was finalized, the engine research and development department in Chengdu also received a mission statement: first, try to add an afterburner to this engine; second, try to add an external bypass to this engine; Third, try to change this engine into a gas turbine.

"There is an engineer named Cockrell in the UK. He recently put forward the idea of a new type of ship called an air-cushion vessel, which should be translated as a hovercraft."
"The principle is to use high-pressure air to form an air cushion between the bottom of the ship and the water surface, and lift the entire hull from the water, thereby greatly reducing the resistance of the hull when sailing, so that the ship can sail at high speed."
"This kind of high-speed ship has great uses in offshore waters, so I want to mobilize some people and materials from the naval department to conduct research and experiments in this direction."
Yun Liang, a 24-year-old lecturer in the Naval Department, talked about his project concept, while Gu Maoxiang, the director of the Naval Engineering Department, wrote down the main points on paper while listening.
"The original idea of the hovercraft was much earlier than this," Gu Maoxiang added after Yun Liang finished speaking, "Actually, in the Austro-Hungarian Empire, someone designed a paragliding boat, which adopted the air cushion to reduce the resistance. You In this paper I brought, Cockerell’s idea is much more reasonable than that of a paragliding boat, and he has done a lot of specific engineering calculations. But Cockerell only has the calculation process and no design concept drawings. Can you make it yourself? Does it complete?"
"I should be able to. If the project starts, I will first conduct another engineering calculation myself, and then design after I pass it. The engineering ship model can be made within a year."
Gu Maoxiang: "How many people and how much money do you need to make this hovercraft?"
"Manpower, seven or eight should be about the same. I don't know much about the money. I probably need one or two jet engines like those on airplanes, and one or two piston and propeller engines, and then some basic materials and consumables for shipbuilding. "
Gu Maoxiang: "Let me contact the Department of Aeronautical Engineering for engines, and I should be able to give you one or two old ones. Others... It shouldn't be too late to solve them when you enter the actual ship construction."
Chapter 125, Lying down to win
"Comrades, comrades, please listen to me."
"Maozd, the most authoritative communist theorist in the world today, has not expressed his opinion on this issue. We need to listen to Maozd's views on this issue before the debate can be convincing."
In the noisy meeting place, the deputy director of PEM International, Scharkovsky, motioned everyone to be quiet, said the above words, and then looked directly at Gomulka.
Gomulka felt that he could not refute this statement, but could only agree: "I am very glad, Comrade Scharkovsky. After all, you did not quote Stalin as an argument against me. So, we have Then pay attention to Comrade Maozd's opinion on this issue."
