Ning Lei went to Peking with his plan satisfied, but Liang Yuan grabbed his hair and was worried. In the whole plan, the source of foreign exchange Liang Yuan wrote about selling air conditioning fans overseas and newly developed air purifiers in the laboratory. After a year of market inspection, the sales of air conditioning fans in foreign countries this year can be increased. In addition to several major industrial countries such as Britain, France, Germany, the United States and Japan, foreign agents have begun to extend their channels to second- and third-rate European countries and American countries. In economically underdeveloped areas, cheap air conditioning fans are more popular, so air conditioning fans can be sold in the overseas market about 400 to 5 million US dollars.

Although Liang Yuan has handed over all the patents for air conditioning fans, the entire overseas sales channel has been in Liang Yuan's hands for after-sales maintenance and other matters. In addition, Liang Yuan has a very strong influence on Wang Weiguo. In the future, when building a major repair factory for the F14 fighter jet, he would have to join the company. Therefore, Liang Yuan transferred the overseas income of air conditioning fans to his own disposable funds early on.

The first air purifier prototype was successfully trial-produced on March 10th with Su Liangyu's full research and development. At the same time, the leafless electric fan was also offline at the same time. Liang Yuan arranged for people to produce hundreds of trial sales prototypes of air purifiers and leafless electric fans, and sent them to foreign channel partners one by one by one. Air purifiers are not uncommon abroad, such as Philips in the Netherlands, General Electric in the United States, and Westinghouse in the United States, but after combining leafless electric fans, this thing is a bit strange.

As early as late last year, Liang Yuan commissioned Chu Huifen's lover Zhang Jianxin to transport a large amount of aviation information collected from the United States to the country one after another. From the latest version of reference books, to the newly published engine subsystem paper, to the reflection and outlook of the entire aviation industry, Zhang Jianxin sent back more than 5,000 copies of information. Li Yuanling specially built a small library in the gas engine laboratory, and then installed all the information. This library has also become one of the most popular places for gas engine laboratory among technicians.

People who have not experienced that era cannot imagine how technicians who went abroad in the 1980s cut out dozens of dollars from the daily meal expenses of three dollars a day to buy their favorite reference books or related materials. In that era, the most things that people from abroad brought back when they returned. One type was various household appliances, and the other type was various books and documents. No matter how difficult the world was, there would always be excellent Chinese people standing out. They would stand up and act as the real backbone of the Republic.

The sporadic purchasing power of individual technicians can keep up with Liang Yuan's premeditated "sweeping goods". After discovering that Zhang Jianxin was extremely efficient, Liang Yuan invested all the remaining more than 100,000 US dollars in hand in this work. The so-called money can make the devil push the mill. Soon after, Liang Yuan received the "Integrated High-Performance Turbine Engine Technology Plan" that the United States only began to implement in 1987, which is the ihptet plan that is familiar to later generations.

This engine development plan promoted by the US Department of Defense and combined with the US Air Force, the National Aeronautics and Space Administration, the Department of Defense's High-tech Pre-Research Bureau (DAP), the US Army and the US Navy and other departments can be said to be the most important guarantee for American Aviation Power to stand out in the world in the new century.

The goal of the ihptet plan is to double the aviation propulsion system capabilities by 2005, that is, the engine's thrust-to-weight ratio will increase by 100% and 120%. The fuel consumption rate will be reduced by 30% and 40%, and the production and maintenance costs will be reduced by 35% and 60%. After the new century, when the United States took stock of the gains of the ihptet plan, it found that the goal planned for that year had been achieved by 80%. At that time, American aviation power had completely dominated the world and Dugu Qiubai.

At that time, the Republic also proposed a plan for bearish power development. More than ten years later, when Americans took stock of their own gains, the Republic changed the ultimate goal of the bearish power development plan in the 1980s to the international popular standard at that time. The entire plan was still exciting and looked beautiful, and then patted its butt and continued to import aircraft engines from our great neighbors.

This time, Zhang Jianxin not only brought back a lot of public information about the ihptet plan from the United States, but also got back many technical details of the ihptet plan and the engine breakthrough direction that the United States chose to focus on.

Li Yuanling was excited to see a series of technical documents such as small aspect ratio backswept fan, flame retardant titanium alloy compressor material, dual alloy compressor disk, brush seal, ceramic composite combustion chamber flame cylinder floating wall, ‘ultra-cool’ turbine blades and spherical convergence-adjusted tail nozzle (scfn). Circular graded combustion chamber, ceramic bearing, stationary vortex flame stabilization combustion chamber, combustion chamber active temperature control, ceramic matrix composite flame cylinder, carbon carbon composite turbine, ceramic material turbine, magnet floating bearing, gas film bearing, skeleton structure, built-in integrated starter generator, model-based distributed control system, non-steady state computational fluid mechanics (cfd) simulation technology and jet control vector nozzle, etc., and a few praised Liang Yuan. Even the name of Liang Yuan's kindergarten era was turned out by the excited Li Yuanling.

Although the things Zhang Jianxin got did not involve technology and detailed development data, it was enough to point out the key direction for Li Yuanling's subsequent research work. For scientific research, having clear goals and aimless clueless experiments are basically two concepts.

Li Yuanling took the technicians from the gas engine laboratory to sort out the information Liang Yuan got back in categories and according to the development difficulty. Finally, according to his professional strengths, Li Yuanling decided to start with the engine fan blades and focus on the R&D first on the small aspect ratio and then swept the fan.

Liang Yuan had to admit that his mother's attainment in fans is really talented. She built a mathematical model of a small aspect ratio swept fan in just one month. Although this thing is still far from being applied to the engine, for the scientific community, mathematics is the mother of all sciences. As long as there is no problem in mathematics, this thing will definitely be realized in the future. The emergence of modern jet turbofan engines is also based on Wu Zhonghua's theory of mechanical impeller ternary flow.

Although it is not possible to use aero engines for the current small aspect ratio swept fans, there is still no problem with the use of air purifiers. As for single-pole fans, small aspect ratio swept fans can increase the flow rate by 20% compared to the ordinary foliar fan under the same revolution, and the power consumed is lower than that of ordinary foliar fans. For fans, it is possible to obtain greater air flow or flow rate with less power.

Liang Yuan carried the bladeless electric fan, the base of the air purifier and various flow data, grabbed his mother and kept her from letting him down. After softening and hard bubbles, Li Yuanling made a special aerodynamic optimization of the revolutions of the bladeless electric fan and the air purifier fan according to the mathematical model of the small aspect ratio that he just made. The things Li Yuanling made were all running at supersonic conditions according to the fan rotation speed. Liang Yuan dared not take it over and use it directly without modification. If the fan data is not modified, it is possible that the bladeless electric fan will blow people away.

"Did Lao Su see it? This fan is equivalent to the sky-roaring monkey specially designed by Professor Qian Xuesen for a firecracker factory. The technical content is excellent." Liang Yuan once carried the swept-back fan that had just been removed from the line and was very strangely shaped and boasted to Su Liangyu proudly. After all, the practical application of the swept-back fan in later generations was only after the new century that it appeared on the general and rr aircraft engines one after another.

It turns out that foreign channel dealers who sell air conditioning fans began to disagree with what Liang Yuan said about the new products in 1988. Many people think that something like air conditioning fans is relatively low in technical content and wins by thinking. It is the super-level performance of the Chinese home appliance industry, and can only rely on low prices to meet the low-end market demand abroad. Therefore, after many sellers learned about the price range of Liang Yuan’s new products, they said that the trial sales samples should not only be provided for free, but if the samples do not meet the local consumption habits, Liang Yuan also needs to provide channel dealers with a certain amount of economic compensation to compensate channel dealers for economic losses in time, manpower, etc.

At present, Liang Haiping is still a little innocent. He is very angry at the requests made by foreign channel dealers, but Liang Yuan did not hesitate to provide written endorsement for the requests of foreign channel dealers.

"It's not that they don't have confidence in their products. Now that they have requested this, we can just get a little bit darker on advance payments in the future." Liang Yuan said with a smile.

Those who followed the trial sales samples abroad were also the sales elites selected by Liang Haiping from the entire Suifenhe market. Although their ability in foreign marketing is useless, they can only be assured and reliable as collecting market reactions.

On March 12, all the trial-sale prototypes and personnel set off to leave China. As a result, it took only one week for good news in the overseas market. Because the various certifications of air purifiers are relatively complicated, they are only in some outlets to create momentum. There is no official sale yet, but the leafless electric fan is already very popular.

Liang Yuan's early pilot program included 900 leafless electric fans, each of which was equipped with 300 leaves, with no advertisements. In just two days, nearly 100 were sold directly by the UK and West Germany. Liang Yuan's channel partner, Wharton Home Appliances Sales Center, New York, bought 160 leavesless electric fans in two days without any advertisements. Faced with this situation, even a fool knew that this thing was a super gold mine.

According to Liang Yuan's estimate, the annual sales of single-leafless electric fans can reach at least 30 million US dollars overseas. This data is also the first-year actual sales record of John Smith, the inventor of the leafless electric fans in his previous life. The air purifier should be able to achieve sales of about 20 million in Liang Yuan's mind. In this way, at least 50 million US dollars will be held. It will be very simple to introduce a gem turboshaft engine from Rolls-Royce in the UK, and there will be no financial pressure. However, I thought that just after I learned the good news in the overseas market, I fell into the bottomless pit of buying f14 before I could more than 24 hours.

In terms of the Chinese Air Force organization, an air combat squad consists of at least four aircraft, which means that Liang Yuan must get hundreds of millions of dollars in cash in just four months, and also have to deal with Grumman and the US Congress. He must make the F14 fighter cruise to the Nansha Islands before Vietnam gets hurt and is ready to move, so as to deter this despicable and shameless rogue country.

Liang Yuan picked up the water cup on the coffee table and took a big sip. He stood up and walked around the room for a few times. Finally, he shook his head helplessly. It turned out that he was going to stay in China leisurely and let the overseas market develop naturally. He just kept counting money with peace of mind.

Among the domestic people in the 1980s, except for whom he could get hundreds of millions of dollars in a short period of time, it was a pity that none of these people knew about lending and borrowing, so he had to go abroad to eat coolies. Liang Yuan thought to himself.
