METHOD AND DEVICE FOR REDUCTION OF DRAG FORCE OF MOBILE TAKE-OFF AND LANDING PLATFORM

摘要

FIELD: transportation of assembly and disassembly take-off and landing platforms by helicopter external suspension. SUBSTANCE: mobile platform is transformed into long structure forming a longitudinal passage which is shielded against air flow. Platform is stabilized longitudinally relative to incoming flow. Device for realization of this method consists of plating assembled from three longitudinal sections interconnected by means of hinges which is transformed into transport configuration in form of trihedron prism with longitudinal passage which is shielded by means of board 3 which is mounted in its opening. Device is provided with ears 5 for connecting the sections and board 3 with ropes 6 of helicopter external store. Stabilization of platform is effected by means of articulated stabilizers 7 secured to sections 1 by means of hinges 8. Sections, stabilizers 7 and board 3 are set in working position by means of retaining rods 9. EFFECT: reduction of drag force acting on platform transported by helicopter as external store.
