Payload launcher, especially for spacecraft satellite - has intermediate element with freewheeling mechanism for payload supporting plate in form of radial arms with couplings

摘要

The launcher consists of a base (11) with a reference axis (z-z) designed to be mounted on a support (S), an intermediate member (12) which can rotate about the reference axis, a drive (22) for the intermediate member and a plate (13) which is able to apply an axial thrust to the payload in a transverse direction relative to the axis (z-z). The plate is mounted on the intermediate member via a freewheeling mechanism (27) which allows it to rotate in one direction only. The plate is in the form of a series of radial arms with coupling elements (20, 21) on their ends in the form of axial bosses which engage with matching recesses in the payload.The drive can be in the form of an elastic energy storage member such as a spiral spring equipped with axial thrust and spiral motion guides (15).In a variant of the design, the axial thrust can be provided by a cylinder with a piston and pyrotechnic charge. ADVANTAGE - Launches payload with a moderate lengthwise thrust effort.
