A damping device for an aerostatic device, comprises a male part 14 having a projecting portion 16, a female part 10 having a channel 12 in which the projecting portion 16 of the male part 14 is slidably receivable, means 22 for providing a magnetic field at or adjacent to the projecting portion 16 of the male part 14 and/or the channel 12 of the female part 10, and magnetic oil 26 interposed between the projecting portion 16 of the male part 14 and the channel 12 of the female part 10. The in use magnetic oil 26 being retained in position by the magnetic field, so that undesirable movement of the male part 14 and/or female part 10 is damped by the oil 26 without the oil 26 being displaced from the projecting portion 16 and/or the channel 12. |
