JOINT OF FLIGHT VEHICLE BODY TO BOTTOM

FIELD: space-rocket engineering, applicable in designing of flight vehicles, having sealed detachable connections to bottoms, hatches, etc. ^ SUBSTANCE: an annular groove is made in the body bottom frame. Bulges are provided an the bottom concentrically to the groove, they are positioned in the annular groove of the bottom frame. Made in the bottom frame concentrically to the annular are slots. An annular groove may be made on the bottom concentrically to the bosses, a sealing ring of radial seal is positioned in it. The bottom frame has a cylindrical or tapered sealed surface. A segment-shaped retainer may be fastened on the bottom by a fastener, for example, by a bolt, the hole for the fastener in it is made eccentrically to the outer surface of rotation. The retainer is conjugate on the outer surface to a groove concentric to it, made in one of the bosses of the bottom frame. The angular groove on the bottom frame and the bulges on the bottom may be torus-shaped. ^ EFFECT: reduced mass of the joint, enhanced protection against external actions, as well as improved its operating properties. ^ 4 cl, 6 dwg
