[QUOTE]Originally posted by Bond, James Bond: [QB] [QUOTE]Originally posted by Nim: [qb] That reminds me, if the human-ships can float in free air and even escalate over cloud height, do they really classify as "hovercraft"? All forms of hovercraft rely on the surface or on water for support. What do they call those things on Starfleet ships, the devices that make the ship stop or stand still? The pads on the Matrix-ships must be like those. Friction generators, or something. But then what makes them go forward or up? :confused: [/qb][/QUOTE]I always figured them to either be some new more powerful type of electrostatic repulsor system or more likely an arcjet engine: [i]Arcjets For electrothermal propulsion systems to achieve exhaust velocities much higher than 10 000 ms-1, portions of the propellant flow must attain temperatures in excess of 10 000 K while being kept out of contact with the engine component walls. Arcjets accomplish this by passing the propellant through an electric arc that heats it before it expands through a nozzle. Core arc temperatures of 10 000 to 20 000 K mean that exhaust velocities of 5000 - 6000 ms-1 (Isp = 500 - 600 s) at efficiencies of around 40% are possible using catalytically decomposed hydrazine. Arcjet thrusters entered commercial use for north-south station keeping on the Telstar-4 series of geostationary communication satellites in 1993. Higher power arcjets providing sufficient thrust for orbit transfer or primary propulsion manoeuvres have been demonstrated on test flights but problems with electrode erosion and availability of sufficient electric power have delayed their introduction for operational missions.[/i] [/QB][/QUOTE]
