DEVICE FOR COLLISION AVOIDANCE helicopter with a high-voltage power lines

摘要

The invention relates to flight control and navigation equipment and can be used to secure any type of aircraft flight (e.g., helicopter) at low altitudes, namely to prevent the helicopter pilots of the danger of collisions with high-voltage power lines (power lines). The aim of the invention is to increase the sensitivity of the device and, as a consequence, increase the range and accuracy of the determination of finding transmission lines without use of additional information from auxiliary sensors radio emitting devices of the primary information, members of the flight and navigation system of the helicopter. The inventive device for preventing the helicopter collision with high voltage power lines includes a block of three orthogonal rigidly mounted on a helicopter magnetometers housing gyro direction to determine the gyroscopic rate of the aircraft, the vertical gyroscope for determining the roll and pitch angles of the aircraft, the first, second, third calculator, a first low-pass filter, a comparing unit, an adder, three orthogonal block rigidly attached to the helicopter body voltage sensors electrical con- cern, the second low-pass filter, the fourth computer module for determining the current vector of the electric field of the Earth, the unit values ​​of the quantities of the electric field of the Earth and logic unit controlling the first and second switches 1 Fig.
