IMPROVED GOVERNMENT SYSTEM FOR SPATIAL ENGINE LAUNCHER

摘要

A spacecraft launcher (1) comprising a main body comprising a motor and a plurality of control surfaces (30) for orienting said launcher, said engine comprising a nozzle (12) defining a jet whose angular amplitude increases with the altitude, characterized in that said control surfaces (30) are arranged downstream of the nozzle (12), so that - for an altitude less than or equal to a first threshold value, said control surfaces (30) are out of the jet at the exit of nozzle (12), - for an altitude greater than the first threshold value, the control surfaces (30) are at least partially in the jet at the nozzle outlet (12).
