Abstract

Empennage déployant à ailettes, pour projectile tiré dans un tube de lancement, comportant un jeu d'ailettes pivotantes A supportées et déployées par un ensemble de motorisation pneumatique. Cet ensemble de motorisation est constitué de deux pièces coaxiales B et C qui coopèrent en combinaison pour former une cavité Q d'admission et d'emmagasinage d'une très faible fraction des gaz de lancement du projectile. La structure coaxiale de la motorisation facilite son integration au projectile et permet le logement d'accessoires. L'empennage est autoverrouillable et comporte un moyen d'assurer un maintien latéral des ailettes durant le lancement du projectile. L'invention s'applique aux projectiles, notamment aux projectiles de mortier dotés de leur propre charge pyrotechnique de lancement
