R101 was one of a pair of British rigid airships completed in 1929 as part of the Imperial Airship Scheme, a British government programme to develop civil airships capable of service on long-distance routes within the British Empire. It was designed and built by an Air Ministry–appointed team and was effectively in competition with the government-funded but privately designed and built R100. When built, it was the world's largest flying craft at 731 ft (223 m) in length, and it was not surpassed by another hydrogen-filled rigid airship until the LZ 129 Hindenburg was launched seven years later.
His Majesty's Airship R100 was a privately designed and built British rigid airship made as part of a two-ship competition to develop a commercial airship service for use on British Empire routes as part of the Imperial Airship Scheme. The other airship, the R101, was built by the British Air Ministry, but both airships were funded by the Government.
The Rolls-Royce Crecy was a British experimental two-stroke, 90-degree, V12, liquid-cooled aero-engine of 1,593.4 cu.in capacity, featuring sleeve valves and direct petrol injection. Initially intended for a high-speed "sprint" interceptor fighter, the Crecy was later seen as an economical high-altitude long-range powerplant. Developed between 1941 and 1946, it was among the most advanced two-stroke aero-engines ever built. The engine never reached flight trials and the project was cancelled in December 1945, overtaken by the progress of jet engine development.
The Rolls-Royce Condor aircraft piston engine is a larger version of the Rolls-Royce Eagle developing up to 675 horsepower. The engine first ran in 1918 and a total of 327 engines were recorded as being built.
The aircraft diesel engine or aero diesel is a diesel-powered aircraft engine. They were used in airships and tried in aircraft in the late 1920s and 1930s, but were never widely adopted until recently. Their main advantages are their excellent specific fuel consumption, the reduced flammability and somewhat higher density of their fuel, but these have been outweighed by a combination of inherent disadvantages compared to gasoline-fueled or turboprop engines. The ever-rising cost of avgas and doubts about its future availability have spurred a resurgence in aircraft diesel engine production in the early 2010s.
The Sunbeam Sikh was a large slow running V-12 piston engine, intended to power airships, under development at the time of the Armistice.
The MA is a straight-4 SOHC 0.9 L, 1.0 L, or 1.2 L engine first introduced in 1982 by Nissan, intended primarily for the K10 series Micra/March model. It shares design similarities with the older E engine, with an 8-valve hemispherical cylinder head but differs in that it uses an aluminium cylinder block. Unusually, the specified ignition timing for the MA10 running on the specified 90 RON gasoline was 2 degrees after top dead centre, reflecting a very high flame speed in the compact combustion chambers.
The British Imperial Airship Scheme was a 1920s project to improve communication between Britain and the distant countries of the British Empire by establishing air routes using airships. The first phase was the construction of two large and technically advanced airships, the R100 and the R101; the R100 made a successful transatlantic crossing to Canada in 1930 in 78 hours. The scheme was terminated in 1931 following the crash in France of R101 in October 1930, while attempting its first flight to India.
The R.102 was a British airship planned in 1930 but never built. The development of R.102 resulted from the Imperial Airship Scheme, when it became apparent that the R100 and R101 airships then being built would not be capable of economic operation over the planned routes. After the crash of the R.101 in October 1930, the project was reevaluated and further airship development abandoned.
The EA827 family of petrol engines was initially developed by Audi under Ludwig Kraus leadership and introduced in 1972 by the B1-series Audi 80, and went on to power many Volkswagen Group models. This is a very robust water-cooled engine configuration for four- up to eight- cylinders. In Brazil this engine was produced under the name Volkswagen AP AP.
The Daimler-Benz DB 602, originally known as Daimler-Benz LOF.6, was a German diesel cycle aero engine designed and built in the early 1930s. It was a liquid-cooled upright V16, and powered the two Hindenburg-class airships. It has roughly the same displacement and weight of the Beardmore Tornado, which was used in the ill-fated R101, but has almost twice the power of the Tornado, showing Daimler-Benz's superior knowledge regarding diesel engine construction.
The Beardmore 160 hp is a British six-cylinder, water-cooled aero engine that first ran in 1916. It was built by Arrol-Johnston and Crossley Motors for William Beardmore and Company as a development of the Beardmore 120 hp, itself a licensed-built version of the Austro-Daimler 6.
The Junkers L2 was Junkers' first water-cooled four-stroke engine and the first to be built on a production line, though only 58 were made. It was a six-cylinder inline engine and powered many Junkers aircraft until replaced by the more powerful L5.
Major George Herbert "Lucky Breeze" Scott, CBE, AFC, was a British airship pilot and engineer. After serving in the Royal Naval Air Service and Royal Air Force during World War I, Scott went on to command the airship R34 on its return Atlantic crossing in 1919, which marked the first transatlantic flight by an airship and the first east–west transatlantic flight by an aircraft of any kind. Subsequently, he worked at the Royal Airship Works in connection with the Imperial Airship Scheme and took part in a second return Atlantic crossing, this time by the R100, in 1930. He was killed later in the year aboard the R100's near-sister, the R101, when it crashed in northern France during a flight to India.
The Fiat AN.1 was an experimental Italian water-cooled diesel straight six cylinder aircraft engine from the late 1920s.
The Beardmore Cyclone was an aero engine produced by William Beardmore & Co with the aim of producing an engine generating a high power output at low revolutions by designing an engine of large displacement. The design did not enter volume production.
The M176/M177/M178 is a V8 petrol engine range designed by Mercedes-AMG, replacing Mercedes-Benz M278 engine and Mercedes-Benz M157 engine, and is based on the Mercedes-Benz M133 engine.
