Linear accelerator concept for capsule acceleration and deceleration between 300 and 760 mph (480 and 1,220 kph). 4.3.1. Capsule Components (Rotor) The rotor of the linear accelerators is very simple – an aluminum blade 49 ft (15 m) long, 1.5 ft (0.45 m) tall, and 2 in. (50 mm) thick. Current flows mainly in the outer 0.4 in. (10 mm) of this blade, allowing it to be hollow to decrease weight and cost. The gap between the rotor and the stator is 0.8 in. (20 mm) on each side. A combination of the capsule control system and electromagnetic centering forces allows the capsule to safely enter, stay within, and exit such a precise gap.
