An acceleration system (30) for accelerating a load, for example for launching 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 cable (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 effected smoothly, initially at low speed and then at progressively increasing speed until the aircraft attains take-off speed. |
