COMPLEX AIRCRAFT OBSERVATIONS ON THE BASIS tethered balloon

摘要

FIELD: transport.;SUBSTANCE: invention relates to development of tethered balloons. Proposed complex comprises balloon gas bag, tether, coupler secured to gas bag whereto attached via top support element are gimbal joint with two degrees of freedom and bottom support element to carry payload, surface control station and communication means to transmit control commands. Payload is arranged for azimuth rotation about bottom support element vertical axis, driven by electric motor controlled by electronic control unit incorporating speed and acceleration transducers. Top support element is furnished with knock-down lock whereto attached is rotary fastener rigidly secure to horizontal top disc. Gimbal joint upper fork is jointed to upper disc bottom surface and accommodates gimbal joint ring fitted on joint first pin. Gimbal joint bar is arranged inside joint ring on joint second pin arranged perpendicular to aforesaid first pin. Gimbal joint bar lower end is jointed to bottom support element. Top ends of two extra dampers are secured to one vertical element of joint fork on the side of two opposite side surfaces. Bottom ends of said dampers are attached to damper bracket arranged on bottom support element so that dampers in initial position are located vertically and in parallel.;EFFECT: stable images, higher accuracy of observation camera alignment, simplified design.;10 cl, 2 dwg
