HIGH-SPEED MODULE OF TRANSPORTATION SYSTEM Russian patent published in 2003 - IPC

FIELD: transport engineering. SUBSTANCE: invention is designed for creating vehicles featuring high aerodynamic characteristics. Proposed high-speed transportation module contains streamlined body with sphere-shaped front part, drop-shaped middle part and cone- shaped rear part. Rear cone-shaped part of body is made with alternating curvature generatrices, and two symmetrical longitudinal sections with negative curvature surface are made on lower surface of body. Said negative curvature sections are mated with side and lower surfaces of body. To decrease drag coefficient and increased dynamic stability, definite relationships of sizes on body members and their shape are proposed. EFFECT: improved energy characteristics of transportation system at increased dynamic stability. 10 cl, 7 dwg
