Rapp 200 Hp
The Rapp 200 hp was a water-cooled 90° V-8 aircraft engine built by Rapp Motorenwerke. Design and development The Rapp 200 hp V-8 engine design was derived from the earlier four-cylinder Rapp 100 hp design approximately around 1915.''BMW Group Archives''. Achtzylinder Rapp - Flugmotor, 200 PS (photo) It had eight cylinders with the same bore and stroke of as the Rapp 100 hp, arranged in two rows of four.Angle. 1921. p. 402Huth. 1920. p. 145-147, 130-134 The engine was said to produce about at 1,350 rpm, while weighing about .Eyb. 1918. p. 125Klamroth. 1916. p. 235 The design of the cylinders and the valvetrain also reflected the design of the Rapp 100 hp four-cylinder. The cylinders of each cylinder row were again arranged in pairs composed of two separate forged steel cylinder liners screwed into the pairwise cast cylinder heads. The cylinder heads had integral cooling jackets and were cast from steel in pairs and then machined. The valve s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reciprocating Engine
A reciprocating engine, also often known as a piston engine, is typically a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles Common features in all types There may be one or more pistons. Each piston is inside a cylinder, into which a gas is intr ...

Rapp Motorenwerke
Rapp Motorenwerke GmbH was a German aircraft engine manufacturer based in Munich, Bavaria. Founded in 1913, the firm changed its name in 1917 to Bayerische Motoren Werke GmbH (BMW). The company later became known as after its engine-production assets and the BMW name were transferred in 1922 to Bayerische Flugzeugwerke (formerly Otto Flugmaschinenfabrik), which was then renamed to Bayerische Motoren Werke AG and subsequently evolved into the automotive manufacturer known today as BMW. Early engines Karl Rapp and Julius Auspitzer founded Rapp Motorenwerke GmbH on 27 October 1913 with a capital stock of Reichsmark, RM 200,000. The company was established in Milbertshofen on the former site of the Munich branch of Flugwerk Deutschland GmbH, a firm at which Karl Rapp had held a leading position and that had gone into liquidation in the summer of 1913.Pierer. 2011. pp. 9–19 General Consul Auspitzer was the company's sole shareholder, with the operational side of the company man ...

Rapp 100 Hp
The Rapp 100 hp was a four-cylinder, SOHC valvetrain liquid-cooled inline aircraft engine built by Rapp Motorenwerke. The engine originated from Karl Rapp's earlier 90 hp four-cylinder that he had designed at the Flugwerk Deutschland GmbH for the 1912/13 Kaiserpreis aircraft engine contest. Design and development Karl Rapp had already designed a 90 hp four-cylinder single overhead camshaft engine with a bore and stroke of at the Munich branch of the Flugwerk Deutschland GmbH for first Kaiserpreis contest in 1912.Pierer. 2011. pp. 9–14Bendemann; Seppeler. 1913, pp. 806–807 This four-cylinder engine however did not perform well in the tests at the contest and was considered too heavy and had a high fuel consumption. Due to lack of success of the aircraft and engine designs produced by Flugwerk Deutschland, the company, where Karl Rapp held a leading position, had to be liquidated in summer 1913.Pletschacher. 1992, p. 124 After a failed attempt to ...

Aircraft Engine
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Most aircraft engines are either piston engines or gas turbines, although a few have been rocket powered and in recent years many small UAVs have used electric motors. Manufacturing industry In commercial aviation the major Western manufacturers of turbofan engines are Pratt & Whitney (a subsidiary of Raytheon Technologies), General Electric, Rolls-Royce, and CFM International (a joint venture of Safran Aircraft Engines and General Electric). Russian manufacturers include the United Engine Corporation, Aviadvigatel and Klimov. Aeroengine Corporation of China was formed in 2016 with the merger of several smaller companies. The largest manufacturer of turboprop engines for general aviation is Pratt & Whitney. General Electric announced in 2015 entrance into the market.

Rapp Rp III
The Rapp Rp III was a six-cylinder, SOHC valvetrain water-cooled inline aircraft engine built by Rapp Motorenwerke. Its design had been based on the previous Rapp 100 hp four-cylinder engine. Design and development When the Rapp Motorenwerke were founded on 27 October 1913 Karl Rapp immediately concentrated on designing new aircraft engines. Besides the Rapp 100 hp four-cylinder, an improved version of FD 1416 engine he had designed previously at Flugwerk Deutschland, he also worked on an six-cylinder aircraft engine for the second Kaiserpreis contest for aviation engines.Pletschacher. 1992. pp. 124–125 This 125 hp engine however was not completed on time for the ''Kaiserpreis'' and further development led to the 150 hp Rapp six-cylinder engine in 1914. The early 150 hp version of this engine was said to have developed roughly around Angle. 1921. p. 402Schuster. 1917. p. 18, states 150 hp at 1320 rpm, 260 kg up to Klamroth. 191 ...

Société Du Carburateur Zénith
(French for ''Zenith carburetor company'') was a French corporation specialized in the making of carburettors for both automotive and aerospace industries. Created in Lyon in 1909 by car manufacturer Rochet-Schneider, it was taken over in 1970 by German company DVG. One of the main carburettor manufacturers of the 20th century, it had factories in Lyon and abroad, including in the United States and the United Kingdom. History Origins In 1903, 1873-born François Baverey bought a Lorraine-Dietrich car. Finding that its engine did not work well, he came to realize this was due to the carburettor not being able to adjust the air/fuel ratio to the engine speed. Although not an engineer, Baverey had a keen interest in mathematics and physics. In 1905, he started working on a new model of carburettor equipped with two fuel nozzles, the second of whom allowed the mixture to keep the same ratio independently of the engine speed. He applied for patent on 30 June 1906 in France, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SOHC
An overhead camshaft (OHC) engine is a piston engine where the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. ''Single overhead camshaft'' (SOHC) engines have one camshaft per bank of cylinders. ''Dual overhead camshaft'' (DOHC, also known as "twin-cam".) engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910. Use of DOHC engines slowly increased from the 1940s, leading to many automobiles by the early 2000s using DOHC engines. Design In an OHC engine, the camshaft is located at the top of the engine, above the combustion chamber. This contrasts the earlier overhead valve engine (OHV) and flathead engine configurations, where the camshaft is located down in the engine block. The valves in both OHC and OHV engines are located above the combustion chamber; however an OHV en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karl Rapp
Karl Friedrich Rapp (24 September 1882 in Ehingen (Danube) – 26 May 1962 in Locarno) was a German founder and owner of the Rapp Motorenwerke GmbH in Munich. In time this company became BMW AG. He is acknowledged by BMW AG as an indirect founder of the company. Early life Little is known of Karl Rapp's childhood and adolescent years. However, it is known that Rapp learned the engineering profession and was employed by Züp automotive company from approx. 1908 to 1911. It is believed he was active as a technical designer with Daimler-Motoren-Gesellschaft until 1912. Rapp left the Daimler-Motoren-Gesellschaft to head a branch of Flugwerk Deutschland GmbH. Aircraft engine manufacturing Flugwerk Deutschland GmbH probably transferred its headquarters from Gelsenkirchen-Rotthausen to Brand (Aachen), Brand near Aachen. The articles of association were ratified on 15 February 1912, and the entry in the Aachen Commercial Register was effected on 5 March 1912. The object of the busin ...
