A propeller is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft with an approximately horizontal axis.
SS Great Britain is a museum ship and former passenger steamship that was advanced for her time. She was the largest passenger ship in the world from 1845 to 1853. She was designed by Isambard Kingdom Brunel (1806–1859), for the Great Western Steamship Company's transatlantic service between Bristol and New York City. While other ships had been built of iron or equipped with a screw propeller, Great Britain was the first to combine these features in a large ocean-going ship. She was the first iron steamer to cross the Atlantic Ocean, which she did in 1845, in 14 days.
A steamship, often referred to as a steamer, is a type of steam-powered vessel, typically ocean-faring and seaworthy, that is propelled by one or more steam engines that typically move (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 19th century; however, there were exceptions that came before. Steamships usually use the prefix designations of "PS" for paddle steamer or "SS" for screw steamer. As paddle steamers became less common, "SS" is incorrectly assumed by many to stand for "steamship". Ships powered by internal combustion engines use a prefix such as "MV" for motor vessel, so it is not correct to use "SS" for most modern vessels.
A steamboat is a boat that is propelled primarily by steam power, typically driving propellers or paddlewheels. The term steamboat is used to refer to small steam-powered vessels working on lakes, rivers, and in short-sea shipping. The development of the steamboat led to the larger steamship, which is a seaworthy and often ocean-going ship.
An ocean liner is a type of passenger ship primarily used for transportation across seas or oceans. Ocean liners may also carry cargo or mail, and may sometimes be used for other purposes. The Queen Mary 2 is the only ocean liner still in service to this day.
A paddle steamer is a steamship or steamboat powered by a steam engine driving paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, whereby the first uses were wheelers driven by animals or humans.
Steam frigates and the smaller steam corvettes, steam sloops, steam gunboats and steam schooners, were steam-powered warships that were not meant to stand in the line of battle. The first such ships were paddle steamers. Later on the invention of screw propulsion enabled construction of screw-powered versions of the traditional frigates, corvettes, sloops and gunboats.
The Fairfield Shipbuilding and Engineering Company, Limited, was a Scottish shipbuilding company in the Govan area on the Clyde in Glasgow. Fairfields, as it is often known, was a major warship builder, turning out many vessels for the Royal Navy and other navies through the First World War and the Second World War. It also built many transatlantic liners, including record-breaking ships for the Cunard Line and Canadian Pacific, such as the Blue Riband-winning sisters RMS Campania and RMS Lucania. At the other end of the scale, Fairfields built fast cross-channel mail steamers and ferries for locations around the world. These included ships for the Bosporus crossing in Istanbul and some of the early ships used by Thomas Cook for developing tourism on the River Nile.
SS City of Glasgow of 1850 was a single-screw iron hulled passenger steamship of the Inman Line. Based on ideas pioneered by Isambard Kingdom Brunel's SS Great Britain of 1845, City of Glasgow established that Atlantic steamships could be operated profitably without government subsidy. After a refit in 1852, she was also the first Atlantic steamship to carry steerage passengers, representing a significant improvement in the conditions experienced by immigrants. In March 1854 City of Glasgow vanished while enroute from Liverpool to Philadelphia with 480 passengers and crew aboard.
William Denny and Brothers Limited, often referred to simply as Denny, was a Scottish shipbuilding company.
A & J Inglis Limited, was a shipbuilding firm founded by Anthony Inglis and his brother John, engineers and shipbuilders in the Partick area of Glasgow, Scotland in 1862. The firm built over 500 ships in a period of just over 100 years. Their Pointhouse Shipyard was at the confluence of the rivers Clyde and Kelvin. They constructed a wide range of ships, including Clyde steamers, paddle steamers and small ocean liners. In wartime, they built small warships, and in the period after World War II, they built a number of whalers.
Neafie, Levy & Co., commonly known as Neafie & Levy, was a Philadelphia, Pennsylvania shipbuilding and engineering firm that existed from the middle of the 19th to the beginning of the 20th century. Described as America's "first specialist marine engineers", Neafie & Levy was probably the first company in the United States to combine the building of iron ships with the manufacture of steam engines to power them. The company was also the largest supplier of screw propellers to other North American shipbuilding firms in its early years, and at its peak in the early 1870s was Philadelphia's busiest and most heavily capitalized shipbuilder.
A marine steam engine is a steam engine that is used to power a ship or boat. This article deals mainly with marine steam engines of the reciprocating type, which were in use from the inception of the steamboat in the early 19th century to their last years of large-scale manufacture during World War II. Reciprocating steam engines were progressively replaced in marine applications during the 20th century by steam turbines and marine diesel engines.
J. and G. Rennie was a British engineering company based in Millwall, London, England. They were involved in manufacture of marine engines, and some complete ships, as well as other diverse onshore engineering projects. An association with railway engines is usually attributed to G. and J. Rennie, which may suggest they used a second company to keep the books separate, and there was also George Rennie & Sons, which is associated with the development and patents of the steam disc engine. All three companies appear to have been in existence at the same time.
SS Archimedes was a steamship built in Britain in 1839. She was the world's first steamship to be driven successfully by a screw propeller.
Henry Wimshurst (1804–1884) was a 19th-century British shipbuilder. Wimshurst was in business at Ratcliffe Cross Dock in east London. He is remembered primarily as the builder of Archimedes, the world's first propeller-driven steamship.
Steam-powered vessels include steamboats and steamships. Smaller steamboats were developed first. They were replaced by larger steamships which were often ocean-going. Steamships required a change in propulsion technology from sail to paddlewheel to screw to steam turbines. The latter innovation changed the design of vessels to one that could move faster through the water. Engine propulsion changed to steam turbine in the early 20th century. In the latter part of the 20th century, these, in turn, were replaced by gas turbines.
RMS Aurania was a British Ocean Liner that was scrapped at Genoa, Italy after 22 years of service (1883-1905).
Thomas Clyde was a ship-owner, founder of the Clyde Steamship Company, and a civil and marine engineer who built the first commercial screw steamer in America.
Several ships have been named Archimedes for Archimedes:
