Aircraft safety system preventing mid-air collision - uses single beam and several radiation surfaces for scanning cylindrical field for foreign objects

摘要

The safety system has a theoretical limitation up to the light velocity. A single beam, transmitted in the flight direction and several three conical radiation sources scan a cylindrical source for foreign flying objects. Their position, distance, flight direction and velocity are detected and the flight path computed and compared with the transmitting aircraft path. The computation and comparison results are displayed on a screen. The drive systems of the transmitting aircraft are affected so that a collision is avoided. After completing the evasive manoevure, the old flight path and velocity are again resumed. The reach of the transmitted beam is at least equal to three times transmitting aircraft velocity, and is variable. The system consists of an image converter with a display screen and a computer, a second computer being provided on board.
