The Lightcraft is a space- or air-vehicle driven by beam-powered propulsion, the energy source powering the craft being external. USOS Seaview Bioactive Materials ISO4Bioact.Mater. ISO 4Information and documentation Rules for the abbreviation of title words and titles of publications Physics of Fluids [13] Another example is in the Earth's magnetosphere, where current sheets separate topologically distinct domains, isolating most of the Earth's ionosphere from the solar wind. [41], An important task in cancer research is developing more precise methods for delivery of medicine to affected areas. The ionization of the gas is caused by the large electromagnetic field intensity generated by the resonance within the cavity. In each of the FIGS. In the film, Seaview fires a ballistic missile with a nuclear warhead to extinguish the Van Allen belt that was set on fire by a space cataclysm. The synchronous machines are directly connected to the grid and need to be properly synchronized during startup. Because rubidium is very easy to be ionized, this element was once thought of as an ion engine fuel for spacecraft. In general there are three MHD wave modes: All these waves have constant phase velocities for all frequencies, and hence there is no dispersion. WebA homopolar generator is a DC electrical generator comprising an electrically conductive disc or cylinder rotating in a plane perpendicular to a uniform static magnetic field. Kerosene and water spits into a new fuel reformate: methane (7080% in volume) and carbon dioxide (2030%) in a first stage: Then methane and water reform in their turn in a second stage into hydrogen, a new fuel of better quality, in a strong endothermic reaction: Thus, the heating capacity of the fuel increases, and the surface of the aircraft cools down. With precise construction and design, generators can be built to produce very precise voltages for certain ranges of shaft speeds. Vortices are an important part of turbulent flow. This can create a moving vortex. 12. An MHD wave propagating at an arbitrary angle with respect to the time independent or bulk field B0 will satisfy the dispersion relation, is the Alfvn speed. Electric generator Shortly after the dissolution of the Soviet Union, funding was cut and the Ayaks program had to evolve, especially as the US government announced the National Aero-Space Plane (NASP) program. They hibernate there, dormant for fifty thousand years at a time, before returning to the galaxy. 2. The velocity streamlines are immediately deflected and decelerated so that the boundary layer separates and forms a toroidal vortex ring.[8]. In the film, Seaview fires a ballistic missile with a nuclear warhead to extinguish the Van Allen belt that was set on fire by a space cataclysm. The openings or slots Large power generation dynamos are now rarely seen due to the now nearly universal use of alternating current for power distribution. [7] Due to the dissipation, this means that sustaining an irrotational viscous vortex requires continuous input of work at the core (for example, by steadily turning a cylinder at the core). Vortices also hold energy in its rotation of the fluid. Therefore an arc-source gaseous electrode such as the electrode more fully described in U.S. Pat. [33] In the early 1990s, a foundation in Japan (Ship & Ocean Foundation (Minato-ku, Tokyo)) built an experimental boat, the Yamato-1, which used a magnetohydrodynamic drive incorporating a superconductor cooled by liquid helium, and could travel at 15km/h.[34]. The cruise speed was about 0.4 meter per second (15 inches per second) during the test in the bay of Santa Barbara, California, in accordance with theoretical predictions. Ayaks WebMagnetohydrodynamics (MHD; also called magneto-fluid dynamics or hydromagnetics) is the study of the magnetic properties and behaviour of electrically conducting fluids. In early 1993, as an answer to the American announcement of the X-30 NASP demonstrator, the Ayaks project integrates into the wider national ORYOL (Russian: pr: "Or'yol", Eagle) program, federating all Russian hypersonic works to design a competing spaceplane as a reusable launch system. The Reapers are a highly-advanced machine race of synthetic-organic starships. That conservation would imply that as the mass concentrated in the center of the cloud to form the Sun, it would spin faster, much like a skater pulling their arms in. This category has the following 20 subcategories, out of 20 total. WebA magnetohydrodynamic drive or MHD accelerator is a method for propelling vehicles using only electric and magnetic fields with no moving parts, accelerating an electrically conductive propellant (liquid or gas) with magnetohydrodynamics.The fluid is directed to the rear and as a reaction, the vehicle accelerates forward.. Gordon, in 1882. 5. Although gaseous electrodes have been suggested in the past as a solution to this problem, it is an object of this invention to provide an improved gaseous electrode using electrically conducting gases such that the electrodes do not wear out even though they may be subjected to high density generator currents. [4], The ebbing salty water flowing past London's Waterloo Bridge interacts with the Earth's magnetic field to produce a potential difference between the two river-banks. Before the connection between magnetism and electricity was discovered, electrostatic generators were invented. r [27] Most astrophysical systems are not in local thermal equilibrium, and therefore require an additional kinematic treatment to describe all the phenomena within the system (see Astrophysical plasma).[28][29]. Because of their inefficiency and the difficulty of insulating machines that produced very high voltages, electrostatic generators had low power ratings, and were never used for generation of commercially significant quantities of electric power. The working principle involves electrification of the propellant (gas or water) which can then be directed by a magnetic field, pushing the vehicle in the opposite direction. [25][26][27][28], Such concept was initially named Magneto-Plasma-Chemical Engine (MPCE),[29][30][31] and the working principle referred to as Chemical Heat Regeneration and Fuel Transformation (CHRFT). Both systems can put the working fluid in motion according to two main designs: Internal flow systems concentrate the MHD interaction in a limited volume, preserving stealth characteristics. WebA nuclear electric rocket (more properly nuclear electric propulsion) is a type of spacecraft propulsion system where thermal energy from a nuclear reactor is converted to electrical energy, which is used to drive an ion thruster or other electrical spacecraft propulsion technology. In September 1996, as part of the Capstone Design Course and the Hypersonic Aero-Propulsion Integration Course at Parks College, Czysz assigned his students to analyze the information gathered, as the ODYSSEUS project. its field electromagnets are powered by the machine's own output. {\displaystyle V_{\text{G}}} For example, if a water bucket is spun at constant angular speed w about its vertical axis, the water will eventually rotate in rigid-body fashion. Generators provide nearly all of the power for electric power grids. [11] Thereafter the three researchers copublished a conference paper summarizing the Western analysis of Ayaks principles. It is only through dissipation of a vortex due to viscosity that a vortex line can end in the fluid, rather than at the boundary of the fluid. The method of claim 14 wherein said electrode is tuned by impedance matching in the cavity to insure the maximum utilization of the radiated energy for the ionization of the gas. Bioactive Materials ISO4Bioact.Mater. ISO 4Information and documentation Rules for the abbreviation of title words and titles of publications Gaseous electrode for [2], In October 2000, a new flight record was set with a flight lasting 10.5 seconds and reaching 71 meters (233feet) using the same laser, but this time providing an on-board plastic ablative propellant, and rotating the body around its axis at high speed (over 10,000rpm) to stabilize the craft with a gyroscopic effect.[8][9][6]. The angular momentum per unit mass relative to the vortex axis is therefore constant, 10; and. Most power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power. WebMagnetohydrodynamics (MHD; also called magneto-fluid dynamics or hydromagnetics) is the study of the magnetic properties and behaviour of electrically conducting fluids. Microwave or RF energy is radiated into the cavity to ionize the gas thereby generating an ionized plasma source from which a gaseous plasma plume may be formed. The improved electrodes of this invention disclose and describe a method of generating a plasma plume by high frequency (HF) electromagnetic wave radiation (microwave or RF wave). The Hunt for Red October Ten years before Petit, Dr. Vladimir I. Krementsov, head of the Nizhny Novgorod Research Institute of Radio Engineering (NIIRT), and Dr Anatoly Klimov, chief of the Moscow Radiotechnical Institute of the Russian Academy of Sciences (MRTI RAS), exposed to William Kaufmann that the MHD bypass system of the Ayaks concept would have been already built in the rumored Aurora secret spaceplane, successor of the Lockheed SR-71 Blackbird.[40][43][44]. In the cases of the absence of forces, the liquid settles. Vortex Vortices form in stirred fluids, and may be observed in smoke rings, whirlpools in the wake of a boat, and the winds surrounding a tropical cyclone, tornado or dust devil.. Vortices are a major component of These wires run below the surface directly in contact with the airflow, their profile following the body of the vehicle. Dimensionless efficient power expression of the cycle is derived. 1. WebEnergy can be changed from one type to another through different methods. Bicycles require energy to power running lights and other equipment. Lift and thrust would arise as a consequence of a pressure difference between the upper and lower surfaces, induced by the Coand effect. Combined cycle power plant 1 embodiment). All charged species within the plasma, from positive and negative ions to free electrons, as well as neutral atoms by the effect of collisions, are accelerated in the same direction by the Lorentz "body" force, which results from the combination of a magnetic field with an orthogonal electric field (hence the name of "cross-field accelerator"), these fields not being in the direction of the acceleration. According to Helmholtz's theorems, a vortex line cannot start or end in the fluid except momentarily, in non-steady flow, while the vortex is forming or dissipating. As used herein RF=1-500 MHZ and microwave=500-10,000 MHZ. Many motors can be mechanically driven to generate electricity; frequently they make acceptable manual generators. After 1891, polyphase alternators were introduced to supply currents of multiple differing phases. 12 is a cross-sectional view of FIG. Some electric bicycles are capable of regenerative braking, where the drive motor is used as a generator to recover some energy during braking. . Their only practical applications were to power early X-ray tubes, and later in some atomic particle accelerators. Increasing current density is limited by Joule heating and water electrolysis in the vicinity of electrodes, and increasing the magnetic field strength is limited by the cost, size and weight (as well as technological limitations) of electromagnets and the power available to feed them. is the nabla operator and The FIG. 8. ISSN:1526-1492(print) ISSN:1526-1506(online) Publication Frequency:Monthly Way, on leave from his job at Westinghouse Electric, assigned his senior-year undergraduate students to develop a submarine with this new propulsion system. FluidsISO 4Information and documentation Rules for the abbreviation of title words and titles of publications View full aims & scope The improvement in the MHD system of claim 8, further comprising a gas shield positioned adjacent a plenum chamber communicating with said cavity and opaque to the passage of said gas but transparent to the passage of the high frequency power. Shock wave mitigation for thermal control and reduction of the wave drag and form drag. The "dynamo-electric machine" employed self-powering electromagnetic field coils rather than permanent magnets to create the stator field. In recent times, heat and mass transportation have had some of the most recognized and attractive research areas in computational fluid dynamics. The improvement in the MHD system of claim 12, further comprising a telescopic antenna wherein the inert and the outer conductive members are movable relative to one another thereby providing for the matching of the impedance of the high frequency power input and the cavity. By leaving the vehicle's power source on the ground and by using ambient atmosphere as a reaction mass for much of its ascent, a Lightcraft could potentially be capable of delivering a very large percentage of its launch mass to orbit as an SSTO, an impossible task for chemical rockets. This boundary layer separation can also occur in the presence of combatting pressure gradients (i.e. The spiral streaks that are taken to be streamlines are in fact clouds of the marker fluid that originally spanned several vortex tubes and were stretched into spiral shapes by the non-uniform flow velocity distribution. WebA nuclear electric rocket (more properly nuclear electric propulsion) is a type of spacecraft propulsion system where thermal energy from a nuclear reactor is converted to electrical energy, which is used to drive an ion thruster or other electrical spacecraft propulsion technology. Combined cycle power plant The nuclear electric rocket terminology is slightly inconsistent, as One is the Joule or Brayton cycle which is a gas turbine cycle and the other is the Rankine cycle which is a steam turbine cycle. 9. This is usually not the case in fusion, space and astrophysical plasmas. The nuclear electric rocket terminology is slightly inconsistent, as Very large power station generators often utilize a separate smaller generator to excite the field coils of the larger. The opposite end of the cavity 22 is closed with a diagnostic antenna which acts as a receiver comprising an outer conductor 28 and an inner conductor 29. For electrostatic generators like the Van de Graaff machine, see, Jedlik and the self-excitation phenomenon, Synchronous generators (alternating current generators), Variable-speed constant-frequency generators, Birmingham Museums trust catalogue, accession number: 1889S00044, Losty, H.H.W & Lewis, D.L. The improvement in the MHD system of claim 8, wherein said gas is ionized by a wave guide connected to said cavity. [7], In April 1997, tests by Leik Myrabo in cooperation with the US Army at White Sands Missile Range demonstrated the basic feasibility to propel objects in this way, using a 10-kW ground-based pulsed carbon dioxide laser (1kJ per pulse, 30s pulse at 10Hz frequency). Westinghouse Electric Corporation An equivalent circuit of a generator and load is shown in the adjacent diagram. HyperMach SonicStar Effects of magnetohydrodynamic unsteady fluid flow over a narrow channel in the axial and radial directions. Positioning the electrode at an angle different than 90 is believed to cause the arc to move in both the circumferential and longitudinal directions. 1. For large countries with advanced weapons/space programs (China, Russia, France, Britain, Israel, US, etc.) G If either positive or negative species dominate the vehicle is put in motion in the opposite direction from the net charge. The word "magnetohydrodynamics" is derived from magneto-meaning magnetic field, A potential difference is created between the center of the disc and the rim (or ends of the cylinder) with an electrical polarity that depends on the direction of rotation and the In such electromagnetic thrusters, the working fluid is most of the time ionized hydrazine, xenon or lithium. A unique example of severe geometric changes is at the trailing edge of a bluff body where the fluid flow deceleration, and therefore boundary layer and vortex formation, is located. This design was inefficient, due to self-cancelling counterflows of current in regions of the disk that were not under the influence of the magnetic field. For the disc generator shown in FIGS. 11 is a cross-sectional view of FIG. Nuclear electric rocket Air is progressively decelerated in the boundary layer in a laminar flow without too much recompression, down to subsonic values as it enters the inlet then the air-breathing jet engines. FIG. Physics of Fluids ISO4Phys. The engines used are usually piston engines, but gas turbines can also be used, and there are even hybrid diesel-gas units, called dual-fuel units. The relative motion between a magnetic field and a conductor creates an electric current. They do not require an exciter circuit because the rotating magnetic field is provided by induction from the stator circuit. The core of a vortex in air is sometimes visible because water vapor condenses as the low pressure of the core causes adiabatic cooling; the funnel of a tornado is an example. {\displaystyle {\vec {\omega }}} Reaper This is present in curved surfaces and general geometry changes like a convex surface. 8A is a third embodiment in schematic partially exploded pictorial illustration of an electrode which may be used in the MHD generator of FIG. WebSDO is designed to help us understand the Sun's influence on Earth and Near-Earth space by studying the solar atmosphere on small scales of space and time and in many wavelengths simultaneously. Category:Energy conversion 3 is a cross-sectional view of FIG. Driven by the execution of the flow in the manufacturing application, the goal of the present analysis The direction of the vorticity vector is defined to be the direction of the axis of rotation of this imaginary ball (according to the right-hand rule) while its length is twice the ball's angular velocity. If higher frequency cavities are required for more efficient plasma production in the embodiments of FIGS. For example, when an airplane engine is started, a vortex usually forms ahead of each propeller, or the turbofan of each jet engine. Vladimir L. Frashtadt. Modern vehicles reach speed up to 2530km/h and can run up to 3540km. Problems with current technologies include expense and slow speed compared to a propeller driven by an engine. Solar Power Generation When the fluid cannot be considered as completely conductive, but the other conditions for ideal MHD are satisfied, it is possible to use an extended model called resistive MHD. Web ISO4 - Physics of Fluids. One is the Joule or Brayton cycle which is a gas turbine cycle and the other is the Rankine cycle which is a steam turbine cycle. Because it is easily ionized, it may be used as a propellant in an ion machine on a spacecraft. In particular, the typical magnetic diffusion times over any scale length present in the system must be longer than any time scale of interest. The nose is shaped as a blunted cone for aerodynamical purpose. Driven by the execution of the flow in the manufacturing application, the goal of the present analysis [7][8][9][10], As the information available out of Russia started to grow, three western academic researchers started to collect the sparse data about Ayaks: Claudio Bruno, professor at the Sapienza University of Rome; Paul A. Czysz, professor at the Parks College of Engineering, Aviation and Technology at Saint Louis University; and S. N. B. Murthy, professor at Purdue University. MHD applies to astrophysics, including stars, the interplanetary medium (space between the planets), and possibly within the interstellar medium (space between the stars) and jets. FIG. So when it was claimed that he saw green lights belonging to the Black Knight on his 1) which receives a main stream of high temperature, electrically conductive plasma at an inlet end as indicated by arrow 12. At 298 watts the average "healthy human" becomes exhausted within 10 minutes. AC has come to dominate due to the ability of AC to be easily transformed to and from very high voltages to permit low losses over large distances. Conceptually, the vorticity could be observed by placing a tiny rough ball at the point in question, free to move with the fluid, and observing how it rotates about its center. For example, in the 1870s Siemens used electromagnetic dynamos to power electric arc furnaces for the production of metals and other materials. When vortices are made visible by smoke or ink trails, they may seem to have spiral pathlines or streamlines. If the energy is never removed, it would consist of circular motion forever. Cooper announced seeing many UFOs throughout his career. The set of equations that describe MHD are a combination of the NavierStokes equations of fluid dynamics and Maxwells equations of electromagnetism. No. Way, on leave from his job at Westinghouse Electric, assigned his senior year undergraduate students to build the operational unit. The modern dynamo, fit for use in industrial applications, was invented independently by Sir Charles Wheatstone, Werner von Siemens and Samuel Alfred Varley. Two or more vortices that are approximately parallel and circulating in the same direction will attract and eventually merge to form a single vortex, whose circulation will equal the sum of the circulations of the constituent vortices.

[2][22], Small-scale ship models were later built and studied extensively in the laboratory, leading to successful comparisons between the measurements and the theoretical prediction of ship terminal speeds. Efficient Power Characteristic Analysis and Multi-Objective The generator is represented by an abstract generator consisting of an ideal voltage source and an internal impedance. It is more "efficient" in using the heat, it just needs a lot of heat. The improvement of claim 9, wherein said gas is argon. [26] Researchers are attempting to learn more about this correlation to find out whether this method can be used as part of an early warning system for earthquakes. In recent times, heat and mass transportation have had some of the most recognized and attractive research areas in computational fluid dynamics. Therefore, it is a primary object of this invention to provide a structure and method for generating a plasma plume which will cause a diffuse current rather than a localized current to flow from one electrode to an opposing electrode, without requiring a particular angle of orientation with respect to the magnetic field of the MHD generator. Web: In order to study the Marangoni- and buoyancy-driven convection in smaller Reynolds number flow field, a new electrochemical machining model was established by coupling various physical fields, in which the machining gap was defined as 20 mm and the electrolyte conductivity was equal to 8.74 S/m.Through the numerical simulation and Examples of such magnetofluids include plasmas, liquid metals, salt water, and electrolytes. Typically operated by means of pedal power, a converted bicycle trainer, or a foot pump, such generators can be practically used to charge batteries, and in some cases are designed with an integral inverter. A dynamo uses commutators to produce direct current.
