FACILITY FOR AEROGEOPHYSICAL SURVEY ( VARIANTS ) Russian patent published in 2003 - IPC

FIELD: geophysical, distance, search methods realized with use of aircraft. SUBSTANCE: task of invention consists in design of facility for aerogeophysical investigations with high-motion stability that ensures execution of electromagnetic study with high productivity with simultaneous provision for high resolution and depth of investigations. Facility includes aircraft towing electromagnetic system positioned horizontally under it and incorporating hardware unit, emitting antenna and receiving antenna. Electromagnetic system comes in the form of sonde that incorporates bearing case made of several rectilinear sections forming polygon in which turns of emitting antenna and hardware unit are located. Receiving antenna is put on rigged companion element coupled to bearing case of sonde on side opposite to direction of movement. In correspondence with another variant receiving antenna is mounted on platform placed in internal space of sonde for taking it outside on flexible companion element by means of remotely operated mechanism to side opposite to direction of movement. EFFECT: raised functional efficiency of facility. 24 cl, 3 dwg
