Abstract
An electrically powered launcher is disclosed that can accelerate small payloads to orbital velocities. The invention uses a novel geometry to overcome limitations of other design, and allows full exploitation of existing superconducting materials.
Claims12
A linear motor apparatus comprising:
- a primary assembly including a left side element and a right side element, each element including a longitudinal slot,
- a secondary assembly comprises a closed loop, where a left side of the loop is disposed in the longitudinal slot of the left side element and a right side of the loop is disposed in the longitudinal slot of the right side element and where the loop is perpendicular to a direction of launch,
- a payload coupled to the secondary assembly,
- where the secondary assembly is accelerated down a length of the primary assembly when a current is applied to the secondary assembly and where the payload is launched when the secondary assembly reaches a distal end of the primary assembly.
