SUBMARINE FORE EXTREMITY

摘要

shipbuilding ; construction of submarine fore extremity. SUBSTANCE: fore extremity is provided with antenna with sound transparent dome. Conjugated semicircle forming working surface of conformal antenna is located in plane of maximum half-breadths of submarine. All normal sections are made by single maximum permissible radius at sickle-shaped clearance between antenna surface and inner surface of done skin. EFFECT: reduced mass and overall dimensions of sonar complex; simplified procedure of processing signals received by sonar converter; improved antenna directional characteristics. 4 dwg
