ABSTRACT:
The present invention relates to a device for imparting a movement of rotation to a craft with nozzle propulsion system during launching thereof by means of a launching member, said device comprising: a wheel with vanes or fins formed by a section of tube located in the rear extension of the nozzle, the tube section having an outer surface at least partly in permanent contact with the launching member during its path inside said latter, and bearing, on the inside, vanes or fins constituting surfaces deflecting the jet produced by the nozzle, the wheel being divided into distinct annular sectors juxtaposed to form said tube section, each sector extending over an angle at the most equal to 180.degree., and bearing at least one vane or fin; and connecting means comprising at least one locking element associated with each annular sector to render this latter fast with the nozzle in the direction of rotation about the axis of the nozzle and parallel to this axis, said connection means cooperating with the launching member to maintain, upon launching, the wheel in fixed position with respect to the nozzle, and to allow the separation of said device and the craft, on leaving the launching member.
