Ning Lei was satisfied with the plan to go to Beiping, but Liang Yuan grabbed his head and was worried to death, in the whole plan the source of foreign exchange Liang Yuan wrote that the sales of air conditioning fans overseas plus the newly developed air purifier in the real yàn room, which after a year of market testing, this year's sales of air conditioning fans in foreign countries can double, in addition to Britain, France, Germany, the United States, Japan and other major industrial countries, foreign agents began to extend the channel to the second and third rate European countries and American countries, in the economic area cheap air conditioning fans are more popular, so air conditioning fans can be sold in overseas markets about four million to five million US dollars。

Although Liang Yuan has handed over all the patents of the air conditioning fan, the entire overseas sales channel has indeed been in the hands of Liang Yuan for after-sales maintenance and other matters, plus Liang Yuan's influence on Wang Weiguo is very strong, and when the F14 fighter overhaul plant is built in the future, the 257 factory will also have to be pulled into the house, so Liang Yuan has already allocated the overseas income of the air conditioning fan to his disposable funds.

The prototype of the air purifier was successfully produced on March 10 under the full development of Su Liangyu, and the bladeless electric fan was also rolled off the assembly line at the same time, Liang Yuan arranged for his life to produce hundreds of air purifiers and bladeless electric fans after the test sales prototype, and sent them to foreign channel partners one by one by flight, air purifiers are not uncommon abroad, such as Philips in the Netherlands, General Electric in the United States, Westinghouse have production, but after combining bladeless electric fans, this thing is a little unusual.

As early as the late autumn of last year, Liang Yuan entrusted Chu Huifen's lover Zhang Jianxin to collect a large amount of aviation data from the United States and began to ship them back to China in six consecutive years. From the latest version of the reference book. To the motivation subsystem paper just table, until the reflection and outlook of the entire aviation industry, Zhang Jianxin6 has sent back more than 5,000 copies of the materials, Li Yuanling specially built a small library in the gas turbine room, and then loaded all the materials into it, and this library has become one of the most popular locations for technicians in the gas turbine room.

People who have not experienced that era cannot imagine how the technicians who went abroad in the 80s could have pulled out dozens of dollars from the three dollars a day for food to buy their favorite reference books or related materials in just half a month or so. In that era, people who went abroad brought back the most things when they returned. One is all kinds of household appliances, and the other is all kinds of books and literature, no matter how difficult the world is, there will always be outstanding Chinese sons and daughters who stand out. Hold your chest high and act as the true backbone of the republic.

The sporadic purchasing power of individual technicians can catch up with Liang Yuan's premeditated "sweeping", and now Zhang Jianxin is very efficient, Liang Yuan put all the remaining more than 100,000 US dollars in hand into this work, the so-called money can make the devil grind, and soon after Liang Yuan received the "comprehensive high-performance turbine motor technology plan" that the United States only began to implement in 87 years, that is, the IHPTET plan that the world is familiar with.

This motivational exhibition program, which was promoted by the US Department of Defense and jointly formulated by the US Air Force, the National Aeronautics and Space Administration (NASA), the Defense Department's Advanced Research Agency for Advanced Technology (DAPAR), the US Sixth Armed Forces, and the US Navy, can be said to be the most important guarantee for US aviation power to be proud of the world in the new century.

The goal of the IHPTET program is to double the capacity of the aeropropulsion system by 2oo5, i.e. to increase the thrust-to-weight ratio of the motor by 1oo% by 12o%. Fuel consumption rate decreased by 3o% 4o%, production and maintenance costs reduced by 35% 6o%, after the new century, when the United States took stock of the harvest of the IHPTET plan, it felt that the target under the plan had been completed by 8o%, and at that time, the United States aviation power had completely dominated the rivers and lakes, and sought defeat alone.

More than 10 years later, when the Americans took stock of their gains, the Republic revised the ultimate goal of the bearish power exhibition plan in the 80s to the international popular standards at that time. Make the whole plan still exciting, look beautiful, and then pat yourself on the ass and continue to our great neighbor to import aviation motives.

This time, Zhang Jianxin not only got 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 direction of the breakthrough in the United States' choice of priorities.

Li Yuanling looked at things such as a small aspect ratio swept fan, flame-retardant titanium compressor materials, bi-alloy compressor discs, brush seals, ceramic composite combustion chamber flame cylinder floating walls, 'cold' turbine blades and spherical convergence adjustment tail nozzles (SNETS). A series of technical literature, such as circumferential staged combustion chamber, ceramic bearing, standing vortex flame stable combustion chamber, active temperature control of combustion chamber, ceramic matrix composite flame cylinder, carbon-carbon composite turbine, ceramic material turbine, magnetic bearing, air film bearing, skeleton structure, built-in integral starting motor, model-based distributed control system, unsteady computational fluid (CFD) simulation technology and jet control vector nozzle, etc., were very excited, and Liang Yuan was rarely praised. Even Liang Yuan's kindergarten name was turned out by the excited Li Yuanling.

Although the things that Zhang Jianxin got back did not involve the process, and the detailed opening number jù. But it is also enough to point out the key direction for Li Yuanling's follow-up research work, for scientific research work, having a clear goal and aimlessly clueless yàn are fundamentally two concepts.

Li Yuanling took the technicians of the gas turbine room to sort out the information that Liang Yuan got back according to the difficulty, and finally Li Yuanling decided to start with the fan blades of the motor first, and first focus on the small aspect ratio sweep fan.

Liang Yuan had to admit that his wife's attainments in the fan were really talented, and it only took a month to establish the mathematical model of the small Zhanxian ratio swept fan, although this thing is still far from being applied to the motivation, but for the scientific community, mathematics is the mother of science, as long as there is no problem in mathematics, this thing will definitely be realized in the future, and the emergence of modern jet turbofan motors is also based on Wu Zhonghua's mechanical impeller ternary flow theory.

Although it is not possible to use the current small screw than the swept fan on the aviation motor. But there is still no problem with using air purifiers and bladeless electric fans. In the case of monopole fans, the aspect is smaller than that of swept fans. At the same number of revolutions, the flow rate of a fan can be increased by 2o% compared to that of an ordinary blade, and the power consumption is also lower than that of a fan with ordinary blade, which means that the fan can obtain a larger air flow or flow with less power.

Liang Yuan carried a bladeless electric fan, The base of the air purifier and the number of various flow rates jù, hold on to his mother, and let Li Yuanling according to the mathematical model of the small aspect ratio swept fan that he just made, and make a special aerodynamic optimization for the number of revolutions of the bladeless electric fan and the air purifier fan, Li Yuanling made out the things that run according to the fan rotation degree in the sound condition, where does Liang Yuan dare to use it directly without modification, if you don't modify the number of fans, you can just match a high motor with enough power, and it is possible for the bladeless electric fan to blow people away。

"Did Lao Su see it? This fan is equivalent to the monkey specially designed by Professor Qian Xuesen for a firecracker factory, and the technical content is leveraged. Liang Yuan once boasted to Su Liangyu proudly with the very strangely shaped swept fan that had just come off the assembly line, after all, the practical application of the swept fan in later generations was smaller. It was only after the new century that it appeared on the aviation motive of GM and RR.

Many people think that the technical content of air conditioning fans is relatively low, and the thing that wins by thinking is the level of China's home appliance industry, and it can only rely on low prices to meet the low-end market demand of foreign countries, so many sellers learned about the price range of Liang Yuan's new products, and said that the test sales samples should not only be provided for free, if the samples do not meet the local consumption habits, Liang Yuan also needs to provide a certain amount of economic compensation for the channel to make up for the channel in time, manpower, etc.

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

"It's not that they don't have confidence in their products, now that they ask for this, we can be a little black on the advance payment in the future. Liang Yuan said with a smile.

Along with the test sales samples to go abroad, as well as Liang Haiping from the entire Suifenhe market selected sales elites, although the ability in foreign marketing is useless, but the collection of market reactions is still done by their own people to rest assured and reliable.

On March 12th, all the test sales prototypes and personnel all set off for China, and it only took a week for the overseas market to report frequently. There is no official sale for the time being, but the bladeless electric fan has become a hot mess.

Liang Yuan's early pilot three countries, the United States, the United Kingdom, and West Germany, have a total of 900 bladeless electric fans, 300 in each country, and the result is in just two days, without any advertising. Nearly 100 units were directly sold in the UK and West Germany, and Liang Yuan's channel partner in the United States, Wharton Home Appliances Sales Center in New York. I bought 160 bladeless electric fans in two days with only two stores on display, and even a fool would know that this thing is a big gold mine in the face of this situation.

According to Liang Yuan's estimates, the sales of a single bladeless electric fan can reach at least 30 million US dollars a year, this number is also the actual annual sales record of John, Smith, the brighter of the bladeless electric fan in the previous life, and the air purifier should be able to complete about 20 million sales in Liang Yuan's heart, so that he has at least 50 million US dollars in his hand, and the introduction of gem vortex shaft motors from the British Rolls-Royce company will become very simple, and there is basically no financial pressure。

In terms of the establishment of the Chinese Air Force, an air combat squad consisting of at least four aircraft means that Liang Yuan must get hundreds of millions of dollars in cash in just four months, and at the same time, he must also get the Grumman Corporation and the US Congress to make sure that F14 fighter jets can patrol the Spratly Islands before Vietnam is ready to make a move, so as to deter this despicable and shameless rogue state.

Liang Yuan casually took a few sips of the water cup on the coffee table, stood up and walked around the room a few times, and finally shook his head helplessly, it turned out that he was going to stay in the country leisurely, let the overseas market naturally develop, and don't think about the days when you can count the money comfortably.

Among the domestic people in the 80s, except for the fact that they could get hundreds of millions of dollars in a short period of time, they would not be slapped in the face, but unfortunately these people didn't know any of them, let alone even think about it, so they had to go abroad to sell coolies, Liang Yuan thought self-deprecatingly.

Liang Yuan picked up the phone at hand and dialed the numbers, and said after a while: "Uncle, it's me, you put aside the work at hand for a while, and prepare to go abroad with me." ”
