  The idea of extracting electric energy using a magnetohydrodynamic (MHD) generator arranged onboard space capsule is considered. For the conditions at one point on the trajectory of Stardust (NASA space probe) mission, it is numerically demonstrated that an electric power of about 3 MW can be gained by the proposed MHD generator, which amounts to abut 5% of the total enthalpy Cited by: 3.

The performance of a pulsed-heat-source, high-temperature inert gas MHD electrical power generator, which is a candidate space-based laser-to-electrical power converter, is examined by time.

  A laser-induced magnetohydrodynamic (MHD) electric generator, in which the working gas medium is the gas of a gas laser. The coherent light generated by this gas laser is used for ionizing the gas medium circulated in closed cycle by a compressor through the magnetic gap of the generator, to produce electricity. A high specific power output ( MW/kg/sec) MHD generator at the kilowatt output level was designed and built for cyanogen-oxygen operation. The design of the generator is described, as are the modifications to the AERL Mark II facility which were required in order to test the generator.

Mhd Power Generation. The feasibility of a laser-driven MHD generator, as a candidate receiver for a space-based laser power transmission system, was investigated. On the basis of reasonable parameters obtained in the literature, a model of the laser-driven MHD generator was developed with the assumptions of a steady, turbulent, two-dimensional : S.

Choi. Yes, Space Based Laser Platforms Are Real Aug Way back in April of we took a look at the emerging technology of laser weapons in space, primarily to take out “enemy” satellites, and possibly to strike targets on the surface of the g: MHD generator.

An MHD generator produces a direct current output which needs an expensive high power inverter to convert the output into alternating current for connection to the grid. Efficiency Typical efficiencies of MHD generators are around 10 to 20 percent mainly due to the heat lost through the high temperature exhaust.

The magnetohydrodynamic power generator[8] is a device that generates electric power by means of the interaction of a moving fluid (usually a ionized gas or plasma) and a magnetic field.

As all direct conversion processes the MHD generators can also convert thermal energy directly into. The MHD generation or, also known as magneto hydrodynamic power generation is a direct energy conversion system which converts the heat energy directly into electrical energy, without any intermediate mechanical energy conversion, as opposed to the case in all other power generating plants.

Therefore, in this process, substantial fuel economy can be achieved due to the elimination of. 4 1 Lasers: Fundamentals, Types, and Operations N N E 0 E E 1 E 3 E 0 E E 1 2 Fast decay Fast decay Fast decay Pumping Pumping Lasing Lasing (a) (b) Figure Energy level diagram for (a) three- and (b) four level laser systems.

The present paper describes high-density magnetohydrodynamic (MHD) energy conversion in a high-temperature seed-free argon plasma, for which a quasi-three-dimensional numerical simulation and a single-pulse shock-tunnel-based demonstration are conducted. The numerical model simulates the two-dimensional profiles of both the electron and the heavy-particle system of the supersonic argon Cited by: Abstract.

By integrating CSP with the MHD generator as a topping mechanism we gain a synergism that no other power generator to date possesses.

Furthermore by using the high-temperature exhaust plasma to drive a closed-Brayton cycle turbine electricity generator thereafter, we gain additional power output that further amplifies the efficiency of the.
