BMW

Bayerische Motoren Werke AG (German pronunciation: [baˈjɛɐ̯ɪʃə mɔˈtɔʁn̩ ˈvɛɐ̯kə]; German for Bavarian Motor Works), usually known under its abbreviation BMW, is a German luxury automobile, motorcycle, and engine manufacturing company founded in 1916. Headquartered in Munich, Bavaria, Germany, it also owns and produces Mini cars and serves as the parent company of Rolls-Royce Motor Cars. BMW produces motorcycles under BMW Motorrad, and plug-in electric cars under the BMW i sub-brand. It is one of the best-selling luxury automakers in the world. The company is a component of the Euro Stoxx 50 stock market index.

History

BMW was established as a business entity following a restructuring of the Rapp Motorenwerke aircraft manufacturing firm in 1917. After the end of World War I in 1918, BMW was forced to cease aircraft-engine production by the terms of the Versailles Armistice Treaty. The company consequently shifted to motorcycle production as the restrictions of the treaty started to be lifted in 1923, followed by automobiles in 1928–29.

Rapp Motorenwerke

Rapp Motorenwerke GmbH was an aircraft engine manufacturer in Germany. It was in operations at the turn of the 20th Century and underwent numerous mergers and changes before becoming BMW AG.

Early engines

Karl Rapp and Julius Auspitzer founded Karl Rapp Motorenwerke GmbH (Rapp Motorenwerke) with a capital stock of RM 200,000 on 28 October 1913 on the site of Flugwerke Deutschland GmbH (after the company went into liquidation). General Consul Auspitzer was the company's sole shareholder, with the operational side of the company managed by Karl Rapp. The idea was for the new company to build and sell "engines of all types, in particular internal combustion engines for aircraft and motor vehicles", in addition to building an engine for the second Kaiserpreis (Kaiser's Trophy) rally, but it was not ready in time.

Before World War I, Rapp produced both in-line 6-cylinder and V8 cylinder water-cooled aeroengines. The in-line 6-cylinder produced 125 hp @ 215 kg (474 lb); with a 901 cu in (14.8-litre) displacement. Soon, the company made the Rapp II, which increased the power output to 150 hp @ 260 kg (573 lb). Shortly thereafter, early into World War I, the Rapp III 175 hp (actual 162 hp @ 1400 rpm) 295 kg (651 lb) six-cylinder aeroengine was manufactured. The V8 they developed was 1201 cu in (19.7-litre), producing 200 hp @ 300 kg (661 lb).

BMW 003

The BMW 003 (full RLM designation BMW 109-003) was an early axial compressor turbojet engine produced by BMW AG in Germany during World War II. The 003 and the Junkers Jumo 004 were the only German turbojet engines to reach production during World War II.

Work had begun on the design of the BMW 003 before its contemporary, the Jumo 004, but prolonged developmental problems meant that the BMW 003 entered production much later, and the aircraft projects that had been designed with it in mind were re-engined with the Jumo powerplant instead. The most famous case of this was the Messerschmitt Me 262, which used the 003 in two of the V-series prototypes and in the two experimental A-1b aircraft. The only production aircraft to use the BMW 003 were the Heinkel He 162 and the late C-series versions of the Arado Ar 234.

About 500 BMW 003 engines were built in Germany, but very few were ever installed in aircraft. The engine also formed the basis for turbojet development in Japan during the war, and in France and the Soviet Union following the war.

Messerschmitt Me 262

The Messerschmitt Me 262 Schwalbe / Sturmvogel (English: "Swallow"/ "Storm Bird") of Nazi Germany was the world's first operational jet-powered fighter aircraft. Design work started before World War II began, but engine problems and top-level interference kept the aircraft from operational status with the Luftwaffe until mid-1944. Heavily armed, it was faster than any Allied fighter, including the British jet-powered Gloster Meteor. One of the most advanced aviation designs in operational use during World War II, the Me 262 was used in a variety of roles, including light bomber, reconnaissance, and even experimental night fighter versions.

Me 262 pilots claimed a total of 542 Allied kills, although higher claims are sometimes made. The Allies countered its potential effectiveness in the air by attacking the aircraft on the ground and during takeoff and landing. Engine reliability problems, from the pioneering nature of its Junkers Jumo 004 axial-flow turbojet engines—the first ever placed in mass production—and attacks by Allied forces on fuel supplies during the deteriorating late-war situation also reduced the effectiveness of the aircraft as a fighting force. In the end, the Me 262 had a negligible impact on the course of the war as a result of its late introduction and the consequently small numbers put in operational service.

Max Friz

Max Friz (October 1, 1883–June 9, 1966) was a German mechanical engineer specializing in engine design. He was the key contributor of engine design and innovation that led to the founding of Bayerische Motoren Werke AG (BMW) in 1917.

Early life

Assumed to be originally from Urach, very little is known about Friz' youth. It is known however, that at a young age, he apprenticed to the Kuhn steam engine company in Cannstatt starting in 1898. In 1902, he enrolled at the Royal Building Trade School in Stuttgart-Esslingen furthering his engineering skills. In 1906, he was employed by Daimler Motoren Gesellschaft, in the Design Office, making major contributions to the design of the racing engine for the 1914 Mercedes Grand Prix car that won the French Grand Prix.

Friz designed the first practical German aircraft engines in 1912-1913 while at Austro-Daimler. The engines had separate cylinders on the crankcase and an overhead camshaft driven by a vertical shaft and bevel gears. At the end of 1916 the young engineer Max Friz applied for a position with Rapp Motorenwerke. At that time Friz was still working for the Daimler engine company in Untertürkheim, near Stuttgart. However, he was frustrated because the chief engineer, Paul Daimler, ignored the suggestions of his young assistant on engine development. Faced with this situation, Friz remembered his former colleague, Karl Rapp. At first Rapp was going to turn down Friz’s request; however, Josef Popp successfully intervened on Friz’s behalf, because he recognized that Rapp Motorenwerke lacked an able designer.
