The Bristol Proteus was the Bristol Engine Company's first mass-produced gas turbine engine design, a turboprop that delivered just over 4,000 hp (3,000 kW). The Proteus was a reverse-flow gas turbine. Because the second turbine drove no compressor stages, but only the propeller, this engine was classified as a free-turbine. It powered the Bristol Britannia airliner, small naval patrol craft, hovercraft and electrical generating sets. It was also used to power a land-speed record car, the Bluebird-Proteus CN7. After the merger of Bristol with Armstrong Siddeley the engine became the Bristol Siddeley Proteus, and later the Rolls-Royce Proteus. The Proteus was to be superseded by the Bristol Orion which would have given a Britannia a 75% increase in power for cruising faster.
A power take-off or power takeoff (PTO) is any of several methods for taking power from a power source, such as a running engine, and transmitting it to an application such as an attached implement or separate machine.
Overdrive is the operation of an automobile cruising at sustained speed with reduced engine revolutions per minute (RPM), leading to better fuel consumption, lower noise, and lower wear. Use of the term is confused, as it is applied to several different, but related, meanings.
A motorboat, speedboat or powerboat is a boat that is powered by an engine.
A transmission is a machine in a power transmission system, which provides controlled application of power. Often the term 5-speed transmission refers simply to the gearbox, that uses gears and gear trains to provide speed and torque conversions from a rotating power source to another device.
Front-wheel drive (FWD) is a form of engine and transmission layout used in motor vehicles, where the engine drives the front wheels only. Most modern front-wheel-drive vehicles feature a transverse engine, rather than the conventional longitudinal engine arrangement generally found in rear-wheel-drive and four-wheel drive vehicles.
Rear-wheel-drive (RWD) is a form of engine and transmission layout used in motor vehicles, where the engine drives the rear wheels only. Until the late 20th century, rear-wheel drive was the most common configuration for cars. Most rear-wheel drive vehicles feature a longitudinally-mounted engine at the front of the car.
A drive shaft, driveshaft, driving shaft, tailshaft, propeller shaft, or Cardan shaft is a vehicle component for transmitting mechanical power and torque and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them.
The Hotchkiss drive is a shaft drive form of power transmission. It was the dominant means for front-engine, rear-wheel drive layout cars in the 20th century. The name comes from the French automobile manufacturer Hotchkiss, although other makers, such as Peerless, used similar systems before Hotchkiss.
The Autobianchi Primula is a supermini economy car manufactured between 1964 and 1970 by the Italian automaker Autobianchi, partly owned by and later a subsidiary of the Fiat Group. The Primula was a prototype for Fiat's rack and pinion steering and is widely known for its innovative Dante Giacosa-designed front-wheel drive, transverse engine layout — that would be later popularized by the Fiat 128 to ultimately become an industry-standard front drive layout.
A transverse engine is an engine mounted in a vehicle so that the engine's crankshaft axis is perpendicular to the direction of travel. Many modern front-wheel drive vehicles use this engine mounting configuration. Most rear-wheel drive vehicles use a longitudinal engine configuration, where the engine's crankshaft axis is parallel with the direction of travel, except for some rear-mid engine vehicles, which use a transverse engine and transaxle mounted in the rear instead of the front. Despite typically being used in light vehicles, it is not restricted to such designs and has also been used on armoured fighting vehicles to save interior space.
Coventry Premier Limited owned a British car and cyclecar manufacturing business based in Coventry from 1912 to 1923. It changed its name from Premier Cycles to Coventry Premier Ltd in November 1914.
Chevrolet Corvair Powerglide is a two-speed automatic transmission designed specially for the then all-new 1960 Chevrolet Corvair compact car that emerged in the fall of 1959 as Chevrolet's competitor in the then booming small car market. The Corvair was powered by a rear-mounted Chevrolet Turbo-Air 6 engine that necessitated a specially designed transaxle. Corvair Powerglide took the principles of the standard Chevrolet Powerglide and modified them to suit the rear-mounted powertrain location of the new Corvair. The Corvair used the Powerglide for all 10 years it was produced; from 1961 to 1963, Pontiac used a modified version of Corvair Powerglide it called 'TempesTorque' for its front-engine, rear-transaxle Tempest, LeMans and Tempest LeMans cars.
The Allison T40, company designation Allison Model 500, was an early American turboprop engine composed of two Allison T38 power sections driving a contra-rotating propeller via a common gearbox.
The Supermarine Sea Urchin was an unbuilt British racing biplane flying boat designed by the Supermarine Aviation Works to compete in the 1924 Schneider Trophy. It was to be a single seat biplane, powered by a Rolls-Royce Condor V-12 water-cooled engine buried in the fuselage, driving a pusher propeller mounted on the upper wing via geared shafts. It was abandoned without being built owing to problems with the engine and the transmission required to drive the propeller.
In 1996 Yamaha introduced the Royal Star motorcycle. This motorcycle uses the basic power package from the Yamaha Venture Royale.
The Honda VFR1200F is the 7th generation Honda sport touring motorcycle from the VF and VFR line motorcycles powered by a transverse mounted V4 engine. The VFR1200F has several new technologies including the first dual clutch transmission offered on a motorcycle.
The Fiat AS.6 was an unusual Italian 24-cylinder, liquid-cooled V configured aircraft racing engine designed and built in the late-1920s by Fiat especially for the Schneider Trophy air races, but development and running problems meant that it was never able to compete. Although the engine suffered from technical problems, it was later used to set a speed record for piston-powered seaplanes that still stands today.
The drivetrain, also frequently spelled as drive train, or sometimes drive-train, is the group of components of a motor vehicle that deliver power to the driving wheels. This excludes the engine or motor that generates the power. In contrast, the powertrain is considered to include both the engine and/or motor(s), as well as the drivetrain.
Rim-driven thruster is a novel type of propulsion unit for ships which was presented at the Shipbuilding, Machinery & Marine Technology 2010 trade fair (SMM) by the companies Voith and Van der Velden.
