An acceleration system (30) for accelerating a load, for example for launchi ng an aircraft (21), comprises a flywheel (12) driven from a power source (15), the flywheel (22) having a spiral profiled surface (16) for receiving a cabl e (17) a remote end portion of which is connectable to the aircraft (21). The profiled surface (16) ensures that launching of the aircraft (21) is effecte d smoothly, initially at low speed and then at progressively increasing speed until the aircraft attains take-off speed. |
