skyTran, a NASA Space Act company, headquartered at the NASA Ames Research Center near Mountain View, California, is a patented, high-speed, low-cost, elevated Personal Rapid Transportation (PRT) system. The skyTran network of computer-controlled, 2-person “jet-like” vehicles employs unique, state-of-the-art, SkyTran Magnetic Levitation (STML) technology. skyTran moves passengers in a fast, safe, green, and economical manner.
Detailed Solution description
skyTran is a “Next Generation PRT System” that benefits from the lessons of first and second generation PRTs. Thirty years of operation of the Morgantown system has demonstrated that the use of wheels is a major technical weakness in PRT design. Wheel maintenance is a major operational cost as wheels are subject to constant friction, wear, and periodic failure.
Furthermore, the use of wheels limits the safe maximum speed and, therefore, the range of the vehicles is limited to local areas. skyTran addresses this problem by using magnetic levitation (maglev) instead of wheels.
skyTran has successfully demonstrated that its unique passive magnetic levitation systems can be commercially deployed. In skyTran’s maglev system there is no physical contact between the vehicle and the guideway so there is nothing to wear out or fail. When combined with a tested and proven high performance linear synchronous motor, skyTran’s maglev system makes safe, reliable high speed travel possible at up to 150 mph (240 kph).
This rapid transporting allows for large local, regional, and national networks to be built.
