To talk about the distribution of the British aero engine industrial base, we have to go back to the Second World War, the early days of the war German soldiers were sharp, especially during the air war in the Channel.

At that time, in order to prevent the possible bombing of the Luftwaffe from causing heavy damage to the military industry, Britain launched a huge military industrial base construction project codenamed "Shadow Project", and the guiding ideology is very interesting, it is the classic: mountain, scatter, hole!

That's right, the third-line construction launched by the Republic in preparation for war against the Soviet Union was nothing more than a copy and amplification of the British shadow plan, and the guiding ideology of the third-line construction was also formed in Britain at this time.

Think about the hindsight after 2000, it was all kinds of spraying the third-line construction of the Republic of China, but I don't know that these are all based on the successful experience of predecessors, if you really want to spray the third-line construction of the Republic, then why not spray the British shadow factory project first?

The UK was built during World War II shadow factories in various places, mainly in the aviation manufacturing industry.

Rolls-Royce's Grayback Falcon (Merlin) was the main aircraft engine in Britain at that time, and the range of use was huge, and the number of production could not be counted, and the number of engines produced that were not easy to count was actually mostly the masterpiece of the shadow factory.

After the war, some shadow factories were partially abandoned, some continued to operate in secrecy and increased their three-defense capabilities, as underground factories and shelters in response to a nuclear war, and some factories with relatively good transportation environment and complete equipment were gradually converted to surface operation, just as the third-tier factories of the Republic were successively made public after the 80s.

At this time, I have to mention another very capable aero engine boss in the UK, Bristol Aero Engines.

Bristol Air was born during the First World War, when the company's aircraft were the main force of the Royal Air Force, and it was a large company that had a long reputation, and after the First World War, Bristol Air Branch separated into a subsidiary, which is Bristol Aero Engines.

Strictly speaking, Bristol Aero Engine Company is also a little famous in the piston engine era, although later generations mentioned British piston aero engines, everyone thinks of the first liquid-cooled engine of the Grayback Falcon, but there is really no star-shaped air-cooled engine in the UK?

In fact, Bristol Aviation Development Company is the best British technology star air-cooled engine manufacturer, before the successful development of the Rolls-Royce Gray Falcon, to say that the best aero engine in the whole United Kingdom and even Europe, is actually the "Jupiter" air-cooled engine of Bristol Aviation Development Company.

How good is the "Jupiter" engine?

By 1930, a total of 17 countries had licensed the engine, providing power for no less than 262 aircraft, and such engines were definitely the star of aero engines in Europe and the world before the outbreak of World War II.

And it was such a company, but at the outbreak of World War II, because Britain at that time needed fighter jets more, and needed to produce water-cooled engine Grayback Falcon with better performance and more suitable for interception operations, and finally this Bristol Aviation Development had to switch to a large number of Grayback Falcon, and it was still produced in the name of Shadow Factory.

If the British government had not been affected by the war and had not forced Bristol Aviation Development to stop the route of the star-shaped air-cooled engine, perhaps it would not have been Pratt & Whitney's Wasp series in the field of air-cooled engines.

This is the impact of the war, no one can do anything, fortunately, the Bristol Aviation Development Company contributed a lot during the war, and after the war, it received a lot of benefits from the British government openly and secretly, which can further develop and grow.

Bristol in World War II was restricted from developing new aero engines and had to be a foundry, which is completely different from the treatment of Rolls-Royce when it had the opportunity to develop new engines with government support.

The two companies in the war had such diametrically opposed treatment, and there is no need to think about how big the gap between the scientific research and technological capabilities of the two companies will be after the war.

Fortunately, the Bristol Aviation Development Company also did not deserve to die, not only in 1948 by chance to dig up the chief engineer of Rolls-Royce who was responsible for the development of the Avon engine, but even in 1950, taking advantage of the outbreak of the Caoxian War, the British government issued the Avon engine license of the Rolls-Royce company to Bristol free of charge.

In this way, Bristol Aviation Development had the opportunity to enter the post-war jet engine boom, and quickly perfected the difficult Olympus twin-rotor engine.

Going back to Rolls-Royce, the jet engine leader after the war, Rolls-Royce gave birth to aero engine models of less than ten tons, such as Nien, Ebon, Tai, and Spey, and they are all famous.

But a closer look reveals that few people have found any engines with thrust of more than 10 tons before the RB-211.

Since Rolls-Royce does not have an aero engine capable of exceeding 10 tons of thrust, what engine does the famous Concorde supersonic passenger plane use? How can the British explain the power of the 3V bomber that the British made hot-headedly?

Quite simply, this is not also Bristol Aviation Development Company, Bristol began the design of twin-rotor turbojet engines in 1947, and made the Olympus series of high-thrust engines, which developed more than 20 models before and after, and eight models were put into mass production.

Throughout the Olympus family, there is the 301Bom.21 for the Vulcan bomber and the 593 Mk610 for the Concorde supersonic airliner.

The 593 MK610 was developed by Olympus in cooperation with Snecma of France, a big guy with a furious thrust of up to 18.7 tons, and later Concorde service statistics showed that the efficiency of the 593 engine was the highest among all turbojet engines.

The so-called highest efficiency, manifested in a very heavy index of the passenger aircraft "unit fuel consumption rate", the result is that the concorde passenger fuel consumption rate is lower than the car, and the speed of the car is only 1/20 of the speed of the concorde, the 593 engine deserves to be the strongest turbojet at that time, the performance is simply explosive.

In 1959, Bristol Aerospace was in trouble due to a lack of production orders and had to merge with Armstrong Siddeley to become the new Bristol Siddeley.

It was also during this period that the newly established Bristol Siddeley company began to flourish, and in terms of military fighter power systems, the famous Pegasus series used in Harrier fighters was also developed by the company.

In this way, Bristol Siddeley finally had the opportunity to compete with the Derby giants.
