Spacecraft Propulsion
Spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites. In-space propulsion exclusively deals with propulsion systems used in the vacuum of space and should not be confused with space launch or atmospheric entry. Several methods of pragmatic spacecraft propulsion have been developed each having its own drawbacks and advantages. Most satellites have simple reliable chemical thrusters (often monopropellant rockets) or resistojet rockets for orbital station-keeping and some use momentum wheels for attitude control. Soviet bloc satellites have used electric propulsion for decades, and newer Western geo-orbiting spacecraft are starting to use them for north–south station-keeping and orbit raising. Interplanetary vehicles mostly use chemical rockets as well, although a few have used ion thrusters and Hall-effect thrusters (two different types of electric propulsion) to great success. Hypothetical in-space propulsion technologies describe the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plasma Thruster
A plasma propulsion engine is a type of electric propulsion that generates thrust from a quasi-neutral plasma. This is in contrast with ion thruster engines, which generate thrust through extracting an ion current from the plasma source, which is then accelerated to high velocities using grids/anodes. These exist in many forms (see electric propulsion). However, in the scientific literature, the term "plasma thruster" sometimes encompasses thrusters usually designated as "ion engines". Plasma thrusters do not typically use high voltage grids or anodes/cathodes to accelerate the charged particles in the plasma, but rather use currents and potentials that are generated internally to accelerate the ions, resulting in a lower exhaust velocity given the lack of high accelerating voltages. This type of thruster has a number of advantages. The lack of high voltage grids of anodes removes a possible limiting element as a result of grid ion erosion. The plasma exhaust is 'quasi-neutral', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Big Mother Thruster
Mercy Drive is an American hard rock band originally based out of Central Florida, best known for writing and performing entrance themes for World Wrestling Entertainment (WWE) wrestlers, most notably Maven Huffman ("Tattoo") and Randy Orton ("Burn In My Light"). History Mercy Drive originates from the band Big Mother Thruster, founded by Corey Lane and Josh Lyons. Jimmy McGlothin joined the band after meeting Corey in a mosh pit during a Hard Rock Live show in the summer of 2000. Big Mother Thruster was a moderate success. Their momentum increased when they played the Florida circuit. They also gained recognition through supporting other acts including Drowning Pool, Adema and Staind. In 2001, Big Mother Thruster gained bigger exposure through working with WWE (then World Wrestling Federation) and MTV. Four of their songs were used on '' Tough Enough'', a reality show produced by WWE which aired on MTV. The soundtrack to the series went on to sell over 150,000 copies nationwid ...

Hurrying
A hurrier, also sometimes called a coal drawer or coal thruster, was a child or woman employed by a collier to transport the coal that they had mined. Women would normally get the children to help them because of the difficulty of carrying the coal. Common particularly in the early 19th century, the hurrier pulled a corf (basket or small wagon) full of coal along roadways as small as in height. They would often work 12-hour shifts, making several runs down to the coal face and back to the surface again.Channel 4. The Worst Jobs in History - Hurrier. Accessed from the Wayback Machine on 13 November 2009.HalifaxToday.co.uk. The Nature Of Work". Accessed 17 February 2007. Some children came from the workhouses and were apprenticed to the colliers. Adults could not easily do the job because of the size of the roadways, which were limited on the grounds of cost and structural integrity. Hurriers were equipped with a "gurl" belt – a leather belt with a swivel chain linked to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shkadov Thruster
Stellar engines are a class of hypothetical megastructures used to control the motion of a star system. The concept has been introduced by Badescu and Cathcart. Some variants use this energy to produce thrust, and thus accelerate a star and anything orbiting it in a given direction. The creation of such a system would make its builders a type-II civilization on the Kardashev scale. Classes Three classes of stellar engines have been defined. Class A (Shkadov thruster) One of the simplest examples of a stellar engine is the Shkadov thruster (named after Dr. Leonid Shkadov, who first proposed it), or a class-A stellar engine. Such an engine is a stellar propulsion system, consisting of an enormous mirror/light sail—actually a massive type of solar statite large enough to classify as a megastructure—which would balance gravitational attraction towards and radiation pressure away from the star. Since the radiation pressure of the star would now be ''asymmetrical'', i.e. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thruster (surfing)
Simon Anderson (born 7 July 1954) is an Australian competitive surfer, surfboard shaper, and writer. He is credited with the 1980 invention of a three-fin surfboard design, called the "thruster". Early life Anderson grew up in the Northern Beaches area of Sydney with three brothers. His family lived in a house that overlooked Collaroy Beach. In 1977, he won the junior division at the Bells Beach Classic Easter competition and began shaping surfboards in the Sydney suburb of Brookvale. Career In 1977 he won the Bells Beach Classic competition and the Coke Surfabout in Sydney. In October 1980, after seeing a twin fin surfboard with a "trigger point" fin Anderson had the idea for a new version of the existing three fin design which was later dubbed the "thruster". Anderson created a prototype for the "thruster" design and took it on tour with him to Hawaii and California. When he returned to Sydney, he made two more surfboards with similar designs. In 1981, using one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unmanned Underwater Vehicle
Unmanned underwater vehicles (UUV), sometimes known as underwater drones, are submersible vehicles that can operate underwater without a human occupant. These vehicles may be divided into two categories: remotely operated underwater vehicles (ROUVs) and autonomous underwater vehicles (AUVs). ROUVs are remotely controlled by a human operator. AUVs are automated and operate independently of direct human input. Classifications Remotely operated underwater vehicle Remotely Operated Underwater Vehicles (ROUVs) is a subclass of UUVs with the primary purpose of replacing humans for underwater tasks due to the difficult underwater conditions. ROUVs are designed to perform educational or industrial missions. They are manually controlled by an operator to perform tasks that include surveillance and patrolling. The structure of ROUVs disqualify it from being able to operate autonomously. In addition to a camera, actuators, and sensors, ROUVs often include a “gripper” or something ...

Autonomous Underwater Vehicle
An autonomous underwater vehicle (AUV) is a robot that travels underwater without requiring input from an operator. AUVs constitute part of a larger group of undersea systems known as unmanned underwater vehicles, a classification that includes non-autonomous remotely operated underwater vehicles (ROVs) – controlled and powered from the surface by an operator/pilot via an umbilical or using remote control. In military applications an AUV is more often referred to as an unmanned undersea vehicle (UUV). Underwater gliders are a subclass of AUVs. History The first AUV was developed at the Applied Physics Laboratory at the University of Washington as early as 1957 by Stan Murphy, Bob Francois and later on, Terry Ewart. The "Special Purpose Underwater Research Vehicle", or SPURV, was used to study diffusion, acoustic transmission, and submarine wakes. Other early AUVs were developed at the Massachusetts Institute of Technology in the 1970s. One of these is on display in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remotely Operated Underwater Vehicle
A remotely operated underwater vehicle (technically ROUV or just ROV) is a tethered underwater mobile device, commonly called ''underwater robot''. Definition This meaning is different from remote control vehicles operating on land or in the air. ROVs are unoccupied, usually highly maneuverable, and operated by a crew either aboard a vessel/floating platform or on proximate land. They are common in deepwater industries such as offshore hydrocarbon extraction. They are linked to a host ship by a neutrally buoyant tether or, often when working in rough conditions or in deeper water, a load-carrying umbilical cable is used along with a tether management system (TMS). The TMS is either a garage-like device which contains the ROV during lowering through the splash zone or, on larger work-class ROVs, a separate assembly which sits on top of the ROV. The purpose of the TMS is to lengthen and shorten the tether so the effect of cable drag where there are underwater currents is minimize ...

Rim-driven Thruster
The rim-driven thruster, also known as rim-driven propulsor/propeller (or RDP) is a novel type of electric propulsion unit for ships. The concept was proposed by Kort around 1940, but only became commercially practical in the early 21st century due to advances in DC motor controller technology. As of 2017, commercial models of between 500 kW and 3MW are available from manufacturers such as Rolls-Royce, Schottel, Brunvoll, Voith, Van der Velden, etc. Principle The rim-driven thruster is a marine propeller that does not use a central hub for transmission of the driving torque. Conventional hubcentric propellers typically use a shaft driven by a turbine, a diesel engine or an electric motor. The more recent podded drives consist of a propeller driven by a conventional electric motor into an azimuthable gondola under water, but they still incorporate a traditional hubcentric propeller. The blades of the rim-driven thruster, by contrast, are mounted on an outer ring rather ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
