VACUUM MAGNETIC LEVITATION TRANSPORT: DEFINITION OFOPTIMAL CHARACTERISTICS


Abstract: Known to a wide circle of specialists of the transport, the concept of"Evacuated ube ransport echnology" (ET3) <1> is an energy efficient complex magneticlevitation, vacuum and superconducting technology for high-speed ground transportation. Theconcept is presented as the most effective solution to problem increase the speed and capacityof the transport system c is acceptable the cost of moving passengers and cargo, and low costof energy.

To determine the optimal ranges of working parameters of the considered transportationsystem the analysis of the characteristics of the rarefied environment. Based on considerationsof balance of power the cost of maintaining the vacuum in the system and to overcomeaerodynamic drag throughout the speed range of the vehicle (TC) (500÷6500 km/h) it is shownthat the lower bound of the optimal depth of vacuum to the vacuum environment, for the vehicleto relatively low speeds, is 25÷80 PA. For vehicles with speeds close to the maximum I wouldlike to have the pressure of 1 PA or less.

Keywords: vacuum transport, magnetic levitation transport, vacuum system, sparse
environment, aerodynamic characteristics, optimization.
