FIELD: engines and pumps. ^ SUBSTANCE: rear cone is made from extruded material, primarily, carbon fiber-reinforced plastic. Its outer taper surface has recesses confined by planes perpendicular to rear cone axis and constant-width lengthwise webs. Plane of symmetry of said webs crosses generatrixes of rear cone taper surface and rear cone axis. Recesses are arranged regularly on rear cone outer surface. Rear cone thickness at the point of recess decreases toward rear cone edge. Said recesses are filled by heat protection material. The layer of the latter is applied onto outer surface of rear cone, its density being smaller than that of rear cone extruded material. Hole is made in heat protection material over its entire thickness. ^ EFFECT: reduced weight, protection of instruments located nearby rear cone against heating. ^ 2 cl, 2 dwg |
