1. A launching device for a sub-caliber artillery projectile, said launching device comprising:
- a base that incorporates a sliding band at the periphery of a projectile, said base containing a rear part of said projectile and incorporating a thrust surface cooperating with a matching surface at the rear of said projectile;
at least two cylinder sectors surrounding said projectile to ensure guidance by means of exterior ring-shaped support bands, said sectors being in contact by at least one interior support shape with said projectile; and
said cylinder sectors including;
at least one hinge materializing an instantaneous axis, said hinge being detachable during flight, said hinge linking said base to one of said cylinder sectors,said hinge including;
at least one notch on said base, said notch being delimited to the fore by a plane inclined surface and to the rear by a stop surface perpendicular to the longitudinal axis of said projectile, andat least one tooth linked to one of said sectors, wherein said notch cooperating with a matching support surface on said tooth, an edge of said tooth being in contact with said stop surface and constituting said instantaneous axis, said tooth and said notch having a geometry such that said tooth pivots when one of said sectors opens around said instantaneous axis without interfering with said inclined surface.

Abstract
The invention relates to a launching device for a sub-caliber artillery projectile employing a base with sliding band, the base being linked to sabot sectors by means of hinges that can be detached during flight, the opening of the sabot being activated thanks to the dynamic air pressure on the flared shapes to the fore of the sectors, said hinge is flanged radially so as to prevent its becoming separated from the sabot sectors 5 outside of the flight phase.
