Aero-engine is the heart of the airport and is called "the fire of industrial production". The only countries in the world that can independently develop aero-engines with excellent performance are the United States, Russia, Britain, France and so on, and the technical threshold is very high.

The United States is the country with the most advanced aero-engine technology. During World War II, with the influence of its alliance with Britain, the United States obtained the related technology of centrifugal jet engine in whittle, and the Goblin engine technology of axial flow fan from Britain, as well as experts and scientific research talents from all over the country, which laid the foundation for the great development of jet engine technology in this country.

We got rid of the way of imitating production and improving development trend earlier, and started with technological breakthrough and went all out to develop our own cutting-edge technology. The United States has a world-famous engine boss:

One of the aero-engine giants: Wesley-Whitney Enterprise. Wesley-Whitney Company is a subsidiary of United Technologies Corporation, a world-renowned aero-engine manufacturer, occupying nearly half of the global market share of civil engines. The engines produced by the company mainly include military aviation engines: F/KOOC-0/00, F/KOOC-0/7, F/KOOC-0/9, F/KOOC-0/35, PW4000, JT8D-2/KOOC-. Civil aviation engines: large and medium-sized civil engines JT8D, JT9D, PW2000, PW4000-94/ 100/ 12, V2500, PW6000, etc. Pratt & Whitney's early classic engines include: R-1340 "A" engine, J42, J48, J57 and so on.

Semiconductor materials The most prominent technology industry in Japan is probably the industrial production of semiconductor materials. There are Japanese companies in many links of the semiconductor industry chain, such as semiconductor industry, semiconductor devices and electronic components. As early as 1990, Japan's semiconductor industry reached its peak, and Japanese semiconductor enterprises occupied six of the world's top 10 companies, mainly including NEC, Toshiba, Hitachi, Fujitsu, Mitsubishi and Panasonic. Until now, Japanese semiconductor materials still occupy a decisive position in the fields of chip processing machinery and equipment, raw materials and so on. , and has a whole process, perfect system, covering all directions of patent rights of semiconductor materials business circle.

Britain is one of the main research and development bases of new technologies and high value-added industries in the world, especially scientific research involves many scientific fields. In the past, Britain employed 5% of the world's teaching and research with a population of 1%, and published 9% of academic papers. The import volume reached 12% before, second only to the United States. The total number of international awards accounts for about 10% of the world, and there are 78 scientific and reasonable Nobel Prize winners, ranking second in the world. Britain's overall strength is particularly strong, especially in biotechnology, airlines and defense industry.

As an important business entity line, economic power and international financial center in the world, Britain's economic development was once the fifth largest economic system in the world, and it was one of the richest countries in the world with the most developed social economy and the highest living index. Agriculture and animal husbandry in Britain are concentrated in places with high degree of mechanical automation, and the economic benefits are very high: 1% of the working population can meet about 60% of the food demand.

Britain has a large number of coal, natural gas and oil reserves; Britain's important energy output accounts for about 10% of the total GDP, which is quite high in industrialized countries. Britain's service industry, especially commercial banks, finance, shipping, insurance and its commercial services account for a large proportion of GDP and are in a leading position in the world. London, the capital of Beijing, is also one of the best financial, shipping and service stations in the world.

Britain is the largest manufacturer of weapons, petroleum products, computers, televisions and mobile phones in Europe. Education and scientific research in Britain are in a dominant position in the world. Internationally renowned universities such as Cambridge University, Oxford University, London Imperial College London, London School of Economics and Political Science are all located in the UK, and they are the most important cultural and educational core areas in the world outside the United States.

Financial industry: The proportion of British financial industry in GDP is 79%. London is one of the three "monitoring centers" of the world economy (along with new york and Tokyo). Tourism development: the influence of British tourism development on British economic development can not be ignored. In 20 14 years alone, more than 38 million tourists will arrive in Britain, making Britain the sixth largest tourist destination in the world.
