DEVICE FOR DELIVERY OF PAYLOAD INTO CELESTIAL BODY SOIL BULK Russian patent published in 2013 - IPC B64G1/10 

FIELD: transport.

SUBSTANCE: invention relates to aerospace engineering and may be used for complex research of celestial bodies soils. Proposed device comprises hollow structural body with head and cylindrical tail parts. Said body accommodates ballast of medium density exceeding that of said body, openings made in head part and communicated with body inner space wherein located are said ballast and payload. Ballast or its part is made from material that can be extruded by gravity through said openings into ambient medium as a lubricant. Head part is composed of alternating four truncated cones and three cylinders. Fourth cylinder abuts by its larger base on cylindrical tail part. Radial grooves are made on said cylindrical tail part spaced from fourth cone base while lengthwise grooves are made right behind and spaced from the last radial groove. Aluminium straps are fitted in all grooves to extend beyond generatrix of cylindrical tail part. Openings communicated with body inner space are made in second and third cylinders and tail section between fourth cone base and first radial groove radially inclined toward tail part through 30-45 degrees to normal of cone generating lines that start at helical grooves made at cylinder surfaces.

EFFECT: deeper penetration in celestial body soil.
