Omer (submarine)
''Omer'' is the name of a series of human-powered submarines. The submarines were built by students of the ''École de technologie supérieure'' (School of Higher Technology) in Montreal, Quebec, for the International Submarine Races. {{As of, 2014, ''Omer'' teams hold the human-powered submarine world speed records for two-seater and non-propeller categories. Those records are : *8.035 knots for ''Omer 5'' (two-seater) *4.96 knots for ''Omer 11'' (one-seater / non-propeller) ''Omer 11'' is the latest generation of ''Omer'' submarine. History Since 1992, a group of students from the É.T.S. in electrical, mechanical, software and automated automation engineering have taken part in the completion of ''Omer'', a human-powered submarine. The first generation of ''Omer'' was a two-seater submarine that made its mark around the world. Despite the students' efforts and with numerous prizes and awards in conception and innovation, ''Omer'' was not the world's fastest submarine. Ot ...

Human-powered Transport
Human-powered transport is the transport of person(s) and/or goods using human muscle power. Unlike animal-powered transport, human-powered transport has existed since time immemorial in the form of walking, running and swimming. Modern technology has allowed machines to enhance human-power. Although motorization has increased speed and load capacity, many forms of human-powered transport remain popular for reasons of cost, convenience, leisure, physical exercise, and environmentalism. Human-powered transport is sometimes the only type available, especially in underdeveloped or inaccessible regions. Modes Non-vehicular *Crawling (human) *Walking (233 watts at 3 mph) ** Walking bus *Running (1,150 watts at 10 mph) * Sprinting (1,690 watts at 15 mph) *Swimming *Climbing and mountaineering *Ice skating, roller skating, and inline skating * Cross-country skiing Human-powered vehicles (HPVs) Land vehicles Skateboards have the advantage of being so small and light tha ...

Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

École De Technologie Supérieure
École de technologie supérieure (ÉTS) is a public engineering faculty in Montreal, Quebec, Canada. Founded in 1974, the École de technologie supérieure is a constituent of Université du Québec system. Specialized in applied teaching in engineering and technology transfer to companies, where professors, engineers and researchers who are recognized for their practical, industrial and innovative approaches. In any given year, 25% of all engineers receiving a diploma from an engineering school or faculty in the province of Quebec graduate from the ÉTS. Hence, it is ranked first in Quebec and second in Canada for the total number of engineering diplomas awarded annually. Facilities The main address of ÉTS is 1100 Notre-Dame Street West in Montreal's Griffintown neighbourhood, the site of a former O'Keefe Brewery, which was transformed to house the school. It has four buildings devoted to education programs and research activities (and another is planned for opening in 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montreal
Montreal ( ; officially Montréal, ) is the List of the largest municipalities in Canada by population, second-most populous city in Canada and List of towns in Quebec, most populous city in the Provinces and territories of Canada, Canadian province of Quebec. Founded in 1642 as ''Fort Ville-Marie, Ville-Marie'', or "City of Mary", it is named after Mount Royal, the triple-peaked hill around which the early city of Ville-Marie is built. The city is centred on the Island of Montreal, which obtained its name from the same origin as the city, and a few much smaller peripheral islands, the largest of which is Île Bizard. The city is east of the national capital Ottawa, and southwest of the provincial capital, Quebec City. As of 2021, the city had a population of 1,762,949, and a Census Metropolitan Area#Census metropolitan areas, metropolitan population of 4,291,732, making it the List of the largest municipalities in Canada by population, second-largest city, and List of cen ...

Quebec
Quebec ( ; )According to the Canadian government, ''Québec'' (with the acute accent) is the official name in Canadian French and ''Quebec'' (without the accent) is the province's official name in Canadian English is one of the thirteen provinces and territories of Canada. It is the largest province by area and the second-largest by population. Much of the population lives in urban areas along the St. Lawrence River, between the most populous city, Montreal, and the provincial capital, Quebec City. Quebec is the home of the Québécois nation. Located in Central Canada, the province shares land borders with Ontario to the west, Newfoundland and Labrador to the northeast, New Brunswick to the southeast, and a coastal border with Nunavut; in the south it borders Maine, New Hampshire, Vermont, and New York in the United States. Between 1534 and 1763, Quebec was called ''Canada'' and was the most developed colony in New France. Following the Seven Years' War, Quebec b ...

List Of Vehicle Speed Records
The following is a list of speed records for various types of vehicles. This list only presents the single greatest speed achieved in each broad record category; for more information on records under variations of test conditions, see the specific article for each record category. As with many world records, there may be some dispute over the criteria for a record-setting event, the authority of the organization certifying the record, and the actual speed achieved.

Variable Pitch
Flight dynamics in aviation and spacecraft, is the study of the performance, stability, and control of vehicles flying through the air or in outer space. It is concerned with how forces acting on the vehicle determine its velocity and attitude with respect to time. For a fixed-wing aircraft, its changing orientation with respect to the local air flow is represented by two critical angles, the angle of attack of the wing ("alpha") and the angle of attack of the vertical tail, known as the sideslip angle ("beta"). A sideslip angle will arise if an aircraft yaws about its centre of gravity and if the aircraft sideslips bodily, i.e. the centre of gravity moves sideways.Flightwise - Volume 2 - Aircraft Stability And Control, Chris Carpenter 1997, Airlife Publishing Ltd., , p.145 These angles are important because they are the principal source of changes in the aerodynamic forces and moments applied to the aircraft. Spacecraft flight dynamics involve three main forces: propulsive (rock ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) 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 specially 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 (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
