Abstract
A linear drive for use in air and space travel converts the rotational drive of an electromotor into a linear motion of a runner which is secured to at least one flexible coupling member. The flexible coupling member runs around at least one guide member at one end thereof, and around a drive wheel driven by the electric motor at the other end of the flexible coupling member. The rotating drive wheel and the guide member both change the movement direction of the flexible coupling member, whereby the runner can run back and forth between the drive wheel and the guide member.
