What grade is the domestic aircraft engine in the world?

Almost all of the world's mainstream third-generation fighters are powered by turbofan engines, and China started late in the field of turbofan engines, such as J-10 and J-11 were originally imported Russian engines, and in the past ten years, China has made great progress in the field of turbofans. However, on the whole, in terms of air force engine technology, China lags behind the United States by almost a generation, and this gap cannot be caught up overnight, and the time difference is about 10 to 20 years. Russia, on the other hand, has the technical reserves of the Soviet era, and is still stronger than China in terms of technology, but progress has been slow after the collapse of the Soviet Union.

Compared with European countries, China still has a big gap. However, China has never given up research in this area, compared with India and other countries at the same time, it has a great leading advantage, and has the ability to independently develop!

Small bypass engines, that is, fighter engines, are not yet advanced in China, probably at the level of the 90s of the last century in Western countries, and can only be self-sufficient. Large bypass ratio, that is, the engine of a large aircraft, China can be said to be inexperienced, there is currently a big technical bottleneck that cannot be broken through, and it is not ranked, so it can only be imported and cannot be produced by itself.

China's domestic engine is still relatively weak at the world level, and the main fighter uses Qinling, Taihang, and Kunlun, all of which are not vector engines! It has not reached the world's advanced level!

Nonsense, what do you say about China's fifth? China is outside the top ten. It's a fact.

If you don't believe me, I'll give you a list. They are: the United States, Russia, Germany, France, Britain, Israel, Ukraine, Canada, Italy, Sweden.

Don't say you don't know, but you know how much my country's aircraft engine really needs to be solved.

In the middle and lower classes, China has little ability to build military ones. However, it is said that the J-20 will use the domestic vector high-thrust engine WS10 (Taihang), and the J-11 improved version will also be used. It is estimated that this paragraph will be close to the advanced level.

The turbojets and turbofans of domestic aircraft are average, which are not as good as those of Russia and the United States, with little thrust and a short service life.

It ranks last among countries that can build engines....

There is no grade, we don't know how to build a vector engine, and the imitation is to.

Taiyuan's is OK! But basically the engines are made by Ukraine and Russia.

U.S. No. 1. 1. Russia.

Second, the United Kingdom.

3. France first.

Fourth, China is fifth. These five countries are the only countries that have been able to develop or imitate aircraft engines.

The engine will always be a sore spot in China.

The world's three major aero engine manufacturers are: General Electric of the United States, Rolls-Royce of the United Kingdom, and Pratt Whitney Group of Companies.

1. General Electric Company, also known as the General Electric Company of the United States, is the world's largest multinational corporation providing technology and service business. Since Thomas Edison founded General Electric, GE has diversified into a preeminent global company. Today, the company operates in more than 100 countries around the world and employs 315,000 people.

2. Rolls-Royce (also known as Rolls-Royce) is a well-known British aero engine company and the largest aero engine company in Europe, and various aero engines developed by it are widely used in civil and military aircraft around the world. Rolls-Royce is translated from the English rolls-royce, also translated as "Rolls-Royce", or "Rolls-Royce" for short.

3. Pratt &Whitney Group, P&Whitney Group, founded in 1925, is one of the two largest aero engine manufacturing companies in the United States and one of the world's major aviation gas turbine engine manufacturers.

The Pratt & Whitney Group, a division of United Technologies Corporation, is a manufacturer of aircraft engines, gas turbines, and space propulsion systems that design, manufacture, and support.

The engines of the 919 aircraft are not made in China.

The engine of the C919 aircraft was developed by the United States General Electric (GE) and the French company Safran.

The C919 aircraft engine model is a twin-engine turbofan medium CFM LEAP-1C engine.

On December 21, 2009, COMAC and CFM officially signed a letter of intent for strategic cooperation in the power plant of C919 large passenger aircraft in Beijing, and selected the LEAP-X1C engine developed by CFM as the starting power plant of C919 large passenger aircraft.

On July 22, 2015, CFM International's first CFMLEAP-1C engine was delivered to COMAC's manufacturing center in Pudong.

Aircraft engine manufacturers are ranked by General Electric, Rolls-Royce, Pratt Whitney, Snecma and Saturn.

1. General Electric Company

When it comes to General Electric, the first thing that comes to mind may be Edison, one of the top ten inventors of mankind, and this multinational company, founded in 1892, can provide world-leading services and technologies to customers in many countries and regions around the world, covering financial services, aircraft engines, power generation equipment, medical imaging and other fields.

The first CF6 and CFM56 series of civil aviation engines made the company successfully establish a position in this field, in addition to the CF34, GE90 and other series of engines, of which GE90 is also regarded as the world's most powerful civilian jet engine.

2. Rolls-Royce

Rolls-Royce Leaky Ruler is a company founded in 1906 in Westminster, England, based on the aero-engine manufacturing industry, its products include aviation, communication, nuclear power units and other products.

Among them, the aero engine is the most prestigious, whether it is a military aircraft or a civil aircraft have suitable engine products, and is known as the most influential engine provider in the mainline airliner engine market with Tongxin Electrical.

3. Pratt Whitney

Founded in the United States in 1925 and based on the aero engine manufacturing industry, the company integrates R&D, design, manufacturing and sales of aircraft engines, aerospace boosters and gas turbine engines.

The JT9D series, PW2000 series and PW4000 series have been favored by many aircraft manufacturers, and a number of engines have been loaded on the products launched by Airbus and Boeing's top ten aircraft manufacturing companies.

4. French Snecma company

Snecma is an aerospace company headquartered in France, mainly responsible for the R&D, design and production of rocket liquid boosters, propulsion systems and other products, and occupies an important position in the European market.

Around 1970, the company also joined forces with GE to form CFM International, which set a world record for 100 million hours of flight and is still equipped with CFM engines on many aircraft.

5. Saturn Company

Founded in March 1946 after the first chief designer, the engine design bureau launched the first jet engine in the Soviet Union, the TP-1, and later launched a number of turboprops, gas turbines, turbojet engines and rocket engines, further increasing the coverage of the product.

After more than 70 years of development, it has successively reached cooperation with aerospace companies in many countries and regions around the world, among which the more famous ones are Gulfstream in the United States and Rolls-Royce in the United Kingdom.
