Aircraft thrust, assembly, and methods |
摘要 |
Systems and methods for ground-based aircraft thrust systems are provided. In particular, some embodiments use an electromechanical thrust assembly to accelerate aircraft using ground-based energy for takeoff. The assembly can include one or more sleds, one or more maglev tracks, and/or one or more linear motors. Airplanes are loaded onto a sled (e.g., a saddle-shaped sled) that supports and balances the airplane instead of the landing gear aboard the aircraft. The sled levitates above the ground using high-density permanent magnet arrays. Magnetic levitation forces are varied along the assembly to account for lift provided by airflow over the wings. An aircraft thrust system includes a magnetically levitated saddle-shaped sled with airbags that support an aircraft during takeoff acceleration coupled with a linear motor that spans the length of the distance needed for takeoff. |

1. A system comprising:
a sled having airbags thereon adapted to grip an aircraft without a mechanical linkage to the aircraft while supporting the aircraft from underneath the aircraft; an electromagnetic catapult to accelerate the sled along a desired path, wherein the electromagnetic catapult includes a first series of magnets and a second series of magnets that are independently controlled, wherein the first set of magnets can be activated in a first sequence to propel the sled along the desired path and the second series of magnets can be activated in a second sequence to levitate the sled a constant distance above the ground; and an operational control subsystem to provide power switching times and duration to the first series of magnets and the second series of magnets to create a magnetic field to levitate and accelerate the sled. |
