Some car companies are also like this and are always misunderstood. Rolls-Royce, for example, couldn't help it recently, and issued a document in official website clarifying that we are an automobile company and don't produce aircraft engines! Meng, isn't the plane engine always marked RR? I can't believe it!
Friends with this brand should know that there are two Rolls-Royce in the world, one is Rolls-Royce Motor Company, the other is Rolls-Royce Co., Ltd., an airline and a national defense company. It turns out that these two people are really a family. They broke up under the same name in the 1970s. In China, the automobile company is translated as "Rolls Royce", and the airline air defense company is called "Rolls Royce", but the English name has not changed, and foreigners are still confused.
The recent epidemic has dealt a great blow to the aviation industry, and Rolls-Royce has laid off 9,000 people. Many people who don't know the truth think that something happened to Rolls-Royce, and there are less than 9,000 people in the factory! Can't this ruling be closed? Some domestic media don't know whether it is intentional or unintentional, and the title also reads "Rolls-Royce layoffs".
So, on June 1 1, Rolls-Royce Motor Cars released a message in official website, explaining in a respectful and euphemistic tone that our company only produces cars, and its headquarters has more than 2,000 people, which is different from Rolls-Royce, which produces aero-engines! Later, to be on the safe side, Chinese media also sent emails one after another.
Rolls royce was founded by Henry Royce and Charles Rawls. In order to avoid the entanglement between Rolls-Royce and Rolls-Royce, let's use English!
Royce is a mechanical engineer from a poor background. 1904, he built his first car. In the same year, he met Rolls, a car dealer. They hit it off and founded Rolls-Royce on 1906.
In the first few years, this company was just a pure luxury car manufacturer. Silver Ghost, born in 1906, was known as the best car in the world at that time.
The bifurcation of science and technology appears in 19 14. With the outbreak of World War I, 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 early models is 225 HP/1800 rpm, which is not easy to achieve. At the same time, Silver Ghost's engine is only 7.428 liters V6 with 58 horsepower. Eagle production continued until 1925.
By World War II, RR's most famous engine was Merlin Merlin. In fact, according to the tradition of bird naming, it should be translated as "gray-backed falcon". This is a V 12 engine with a displacement of 27 liters, which was a small displacement in World War II. Early power is close to 1000 horsepower. In the later stage, it can be squeezed to 2000 horsepower with two-stage supercharger and advanced fuel.
Merlin is equipped with a hurricane fighter and a fire fighter. Allison V- 1650 authorized by the United States made the famous P-5 1 Mustang, so this engine made great contributions to the victory of 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, Rolls-Royce's favorite 6.75-liter displacement is exactly a quarter of that of the gray-backed Falcon engine. I don't know if this is a simple coincidence.
Accidental separation
RR also developed a larger Griffin vulture engine at the beginning of World War II, but because of the urgency of the war, the research and development was delayed, so we concentrated on putting Merlin into production first. 1943, the company finally found time to promote Griffon, a 37-liter V 12 engine with a power of over 2,200 HP.
Griffin-based spitfire fighter has greatly improved its power and high altitude performance, but its handling character has also become violent, which is not acceptable to all pilots. On the contrary, I feel that the smooth Merlin engine has more soul. Griffin's output can't compare with Merlin's, only more than 8,000 sets have been built.
Jet engines appeared in the late World War II, and Nazi Germany was equipped with the world's first practical jet fighter Me262. In fact, Britain is the birthplace of jet engines, R&; D's footsteps followed closely. 1943, RR produced Welland Whelan engine, improved derwent derwent, and equipped it on the first allied jet fighter "Meteor".
RR successfully developed Nene Ninen at the end of 1944 after developing the previous model. As the power blueprint of many early fighters, this generation of legendary engines was not only copied by the United States, but also sold to the Soviet Union by the British government.
After the end of World War II, the British wartime cabinet was dissolved and a new round of government elections began. Churchill thought the victory was certain, but he lost the election and the left-wing Labour Party was elected as the ruling party. The Labour government agreed to sell the most advanced Nene engine to the Soviet Union to improve international relations. Of course, Russians are very good at this. He only bought dozens of sets and then opened a small house of his own. He was angry and England was born. Nene became the power of MIG-15 fighter after successful imitation. It is estimated that the American pilots were playing MIG-15, and the British had shit in their heads when they scolded the Korean War. Of course, the Labour government has done many wonderful things, which are nothing.
RR has grasped the revolutionary space from piston engine to jet engine in aviation field and developed into a world aero-engine giant. In 1950s, the company successfully developed Conway, the world's first turbofan engine, which was equipped on Boeing 707 and Douglas DC-8. Since then, it has entered the civil aviation market on a large scale and competed with American competitors.
Later, in the early 1960s, the famous Spey engine was divided into military version and civilian version, which was widely used. The military version produced nearly 3,000 sets, and the civilian version produced more than 5,000 sets. The civilian version is installed on the familiar Trident plane.
1975, China introduced 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. This kind of engine and later domestic models were used in the domestic J-7.
RB2 1 1 is a three-rotor engine, which was developed by RR in the middle and late 1960s. Its advantage is that the fan, low-pressure compressor and high-pressure compressor can all work at the best speed, so the efficiency is better.
RB2 1 1 was successfully developed in the early 1970s, but the R&: D process cost RR too much money, which led to the company's crisis and was eventually nationalized. 1973, Rolls-Royce was officially divided into Rolls-Royce for automobiles and Rolls-Royce for aircraft engines.
After the separation, Rolls-Royce developed well and continued to occupy half of the civil aviation engine market. At present, the latest Trent Trent series inherits the triple-rotor design of RB2 1 1 and becomes the power of many wide-body passenger aircraft.
Although Britain has become independent in the field of military aircraft, Rolls-Royce's engine technology is OK, and now the lift fans of F-35 fighters are all produced by them.
So, back to the question at the beginning of the article, the aviation industry has been hit hard by the epidemic. Rolls-Royce laid off 9,000 people, which is not a company at all. However, after talking about the history of this flight, do you think you want to buy a Rolls Royce more ... or the threshold for cars is lower! @20 19
