DEPLOYABLE MAST WITH SPONTANEOUS AUTONOMOUS DEPLOYMENT, AND SATELLITE COMPRISING AT LEAST ONE MAST OF THIS TYPE

摘要

The invention relates to a deployable mast with spontaneousautonomous deployment comprising at least one elementary structuralblock (10) with a longitudinal axis of deployment X, the elementarystructural block comprising two, respectively lower (13) and upperplatforms (12) parallel to a plane YZ orthogonal to the axis X, and Nstages stacked on one another parallel to the axis X, where N is morethan 1, and where i is between 1 and N-1. Each stage (Ei) comprisesat least six flexible longitudinal connection arms (11) which arearticulated by tape springs, which arms are, in the deployed position,on planes parallel to the axis X and are inclined relative to the axis X,the N stages being secured to one another in pairs by means ofconnection platforms (15) parallel to the plane YZ; two adjacent lowerand upper stages (Ei, Ei+1) are offset angularly relative to one anotherby rotation around the axis of deployment X
