- W204624491 abstract "Some very important advances in transportation technology have been related to the modern application of vacuum technology. Since materials technology always lags mechanical design, the advent of vacuum metallurgy in the 1950's time frame was extremely important. The development of vacuum metallurgy enabled the production of many high performance materials that enabled space technology, high performance gas turbines, improved nuclear materials, advanced magnetic, electronic and electrical materials. On a parallel track during the same time frame, the non-metallic materials field also made great strides in providing superior materials for construction, communications, high wear and low friction applications, higher temperature applications and a variety of other new capabilities. For several years Flight Rail Corp. has been developing a transportation system referred to as Vac Trac. Vac Trac operates without any on-board propulsion system and does not depend on traction, the principles of linear induction motors or Maglev for propulsion. The Vac Trac transportation module is guided by wheels, which are normally mounted on rails supported by a truss assembly. The truss assembly is designed to cradle a tube within its structure thus enabling the transportation module to straddle the tube (Power Tube) cradled therein. There is no mechanical attachment between the free piston (prime mover) and the transportation module. Pilot scale tests to one-sixth scale have proven the concept and point to a system that may have some unique applications. Power sources, controls, environmental considerations and the general mechanics of the system are addressed in this paper." @default.
