Patent two-person authorization

A recent news caught everyone's attention: "The cause of the epidemic has hit the aviation industry hard, and Rolls-Royce will lay off 9,000 people." Many fans saw the news and thought Rolls-Royce would face the risk of bankruptcy. In fact, this Rolls-Royce RR is not the familiar Rolls-Royce RR.

Many fans don't know that there are two Rolls Royce companies in the world. A car company, Rolls-Royce? Aviation and Defence Company, rolls royce Company. These two companies were indeed one before the 1970s, but now they have become two independent companies. However, there is not much difference between China's transliteration name and Logo, which often leads to confusion.

Rolls-Royce Motor Company also explained this problem in official website: "Our company only produces luxury cars, and its headquarters currently has more than 2,000 employees, which has nothing to do with Rolls-Royce, which produces aero engines." Later, to be on the safe side, I sent emails to several China media one by one. In fact, they were split into two independent companies as early as 1973. Tell you about this "unknown" Rolls Royce today? Plc airlines.

Divided in two under the war.

At first, the founder of Rolls-Royce was Henry? Royce and Charles? Rolls-Royce is a bad mechanical engineer. 1904 He built his first car. In the same year, he met the car dealer Rolls-Royce, and they hit it off and founded Rolls-Royce on 1906. At first, this company was just a pure luxury car manufacturer. Silver was born in 1906. Ghost was called the most luxurious car in the world at that time.

19 14 When World War I broke out, Britain was in urgent need of airplanes. In response to the national call, rolls royce launched the first aero-engine "Eagle" in 19 15. This is a V 12 gasoline engine with a displacement of 20.3 liters, which adopted the very advanced layout of single overhead camshaft at that time. The maximum power of the early models was 225 horsepower. It was not easy to reach this parameter at that time. Meanwhile, silver? Ghost's engine is only 7.428 liters V6 with 58 horsepower.

Until the end of World War II, the production of aero-engines became one of the company's main businesses. Because 197 1 developed a new aero-engine, it lost money and was heavily in debt, which led to bankruptcy. With the intervention of the British government, the company was reorganized and divided into two companies: automobile and aero-engine. Since then, Rolls-Royce Aeroengine Company has recovered its vitality, while Rolls-Royce Motor Company has been merged by German BMW Company.

The Development History of rolls royce Engine

During World War II, RR's most famous engine was Merlin Merlin. In fact, according to the tradition of bird naming, it should be translated into "grey-backed falcon" This is a V 12 engine with a displacement of 27 liters, which was a small displacement in World War II. The power of early models was nearly 1000 horsepower. In the later stage, it can be squeezed to 2000 horsepower with two-stage supercharger and advanced fuel.

Merlin was equipped on Hurricane and Spitfire fighters, and Allison V- 1650 authorized by the United States made the most famous P-5 1 Mustang fighter at that time, so this engine can be said to have made great contributions to winning World War II. Its total output is 6.5438+0.5 million units, plus the total production in the United States is * * * 0.2 million units. Interestingly, the Rolls-Royce motor's favorite 6.75-liter displacement is just a quarter of that of the Grizzly Falcon engine. I wonder if this is a kind of "little romance".

Rolls royce has well grasped the transformation from piston engine to jet engine in aviation field, and developed into a world aviation engine giant. Conway successfully developed the world's first turbofan engine in 1950s, which was equipped on Boeing 707 and Douglas DC-8. Since then, Conway has entered the civil aviation market on a large scale and competed with American competitors.

Then the famous Spey engine appeared in the early 1960s. The engine is divided into military version and civilian version, which is widely used. The military version has produced nearly 3000 sets, and the civilian version has more than 5000 sets. 1975, China imported the military version of Spey Mk.202, and purchased the patent contract and production drawings. So this engine has a great influence on the aviation industry in China. Domestic JH-7 used this engine and later domestic models.

197 1 year, Rolls-Royce began to develop a unique three-rotor RB2 1 1 engine. Because the three-rotor technology is relatively new, and Rolls-Royce's composite fan technology failed to pass the test, the development cycle of the RB2 1 1 engine project that was hastily launched was delayed for too long, which eventually led to its insufficient financial support and had to accept the help of the British government.

1973, the separated Rolls-Royce really realized that it was necessary to choose a road of aero-engine development that conformed to the market rules, and thus embarked on the road of core engine and verification machine until serialization. After years of development, the RB2 1 1 series three-rotor engines developed by the company have become one of the most successful engine series in contemporary large civil aviation engines. Now the latest Trent Trent series inherits the triple-rotor design of RB2 1 1 and becomes the power of many wide-body passenger aircraft.

Rolls-Royce for China.

In the global large civil engine market, Rolls-Royce and General Electric Company (General? Electric? The company (GE for short) is in full swing. Especially after Airbus and Boeing put the battlefield in China, the competition between Rolls-Royce and General Electric for the aircraft engine market in China became more intense.

At present, Rolls-Royce attaches great importance to the civil aircraft engine market in China. As the representatives of the next generation aircraft technology, Boeing 787 Dreamliner, Airbus A380 and Airbus A350XWB wide-body aircraft all set their sights on the China market, which also means that China will have a huge demand market for aircraft engines. Luo Shijie, president of Rolls-Royce China, said: "Rolls-Royce regards China as the biggest growth market in the next 20 years and chooses China as the center to expand into Asia."

More importantly, Rolls-Royce is striving to become the sole engine supplier of Airbus A350XWB. Of course, GE doesn't want to see this happen. Presumably this contest will be staged in China sooner or later. Compared with Rolls-Royce, GE is a pioneer in China market. If you want to catch up with others, you need to come up with better products and more mature production lines.

According to the news released by Rolls-Royce, the company has lost about 3 billion pounds (about 26.2 billion yuan) in the first half of 2020, and it is expected to lose further 654.38 billion pounds in the second half. As part of the global restructuring, the company expects to lay off employees from July. The number of layoffs will reach 9,000, equivalent to 17% of 52,000 employees worldwide.

Since the outbreak of COVID-19 in the world, the aviation industry is almost at a standstill. In addition to layoffs, Rolls-Royce will also cut spending on factories and facilities. CEO East said: "The impact of the epidemic on the company and the entire aviation industry is unprecedented. We have not created this crisis, but we must face and deal with this crisis, otherwise it will take several years to return to the pre-epidemic level. "

Do you see the difference between these two RR?
