at the circular run up track fig3 a 1 at a stand still the mother spacecraft the attached space shuttle and the maglev sled are supported entirely on the maglev track by the sled wheels the maglev track is rolled slightly inward toward the center of the circular track a short thrust from the starboard rocket motor of the sled fig5 a 2 moves the maglev sled forward slowly the inductrack i magnetic levitation takes effect and the sled is begins to elevate above the maglev track and in so doing the sled wheels are lifted off of the track fig8 c 1 the sled starboard rocket motor shuts down temporarily as magnetic levitation propulsion and guidance increase as the speed of the maglev sled increases the acceleration of the maglev sled because humans are on board in this embodiment is limited to a maximum of 3g 39 s while a high velocity is gradually achieved on the circular track the maglev sled after reaching a maximum velocity attainable with magnetic propulsion switches to a spiraling track at fig3 a 2 the maglev track begins to gradually roll back toward a level attitude as the maglev sled gains velocity through magnetic propulsion the two.
