Abstract
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.
Claims4
An acceleration system comprising a cable (17), an end portion of which is adapted for releasably coupling with a load (11), a rotary member (12) adapted for rotation on an axis (13) and drive means (15) for disengageably engaging with the rotary member (12) so as to rotate the rotary member (12) on the axis (13), and the rotary member (12) is provided with a surface (16) for receiving a portion of the cable (17) remote from the load (11), and the surface (16) has a curved profile, the radial dimension of which increases progressively from the said axis (13) in an arcuate direction of the said axis (13), characterised in that there is provided means for engaging a portion of the said cable (17) remote from the load (11) with the said rotary member (12), while the said rotary member (12) is rotating, so that the portion of the said cable (17) remote from the load (11) locates on the said surface (16) while an end portion of the said cable (17) remote from the load (11) is restrained at a location on the rotary member (12) adjacent to a centre of the rotary member (12).
An acceleration system comprising a cable (26), an end portion of which is adapted for releasably coupling with a load (21), a rotary member (22) adapted for rotation on an axis (23) and drive means (24) for disengageably engaging with the rotary member (22) so as to rotate the rotary member (22) on the axis (23), and an additional rotary member (25) adapted for rotation on a second axis, and an end portion of the said cable (26) remote from the load (21) is attached to the additional rotary member (25), and a second cable (27), an end portion of which is attached to the additional rotary member (25), and the rotary member (22) is provided with a surface (28) for receiving a portion of the said cable (27) remote from the additional rotary member (25), and the surface (28) has a curved profile, the radial dimension of which increases progressively from the said axis (23) in an arcuate direction of the said axis (23), characterised in that there is provided means for engaging a portion of the said cable (27) remote from the additional rotary member (25) with the said rotary member (22), while the said rotary member (22) is rotating, so that the portion of the said cable (27) remote from the additional rotary member (25) locates on the said surface (28) while an end portion of the said cable (27) remote from the additional rotary member (25) is restrained at a location on the rotary member (22) adjacent to a centre of the rotary member (22).
