Method for arranging traffic pattern of unmanned aerial vehicle

Abstract

The invention discloses a method for arranging a traffic pattern of an unmanned aerial vehicle. The method comprises the following steps of: determining each waypoint of the traffic pattern according to factors such as the geographical position of an airport, the approach constant-level flying height H of a plane, the glide line angle lambda of the plane, a waypoint switching distance D and the like; and arranging a point 2 and a point 3 of the traffic pattern on the longitudinal central line of a runway, a point 4 on an elongation line along the direction of the point 2 and the point 3, a point 1 on an elongation line opposite to the direction of the point 2 and the point 3, a point 0 and a point 5 on the same side of the runway and a point 6 and a point 7 at an intersection position between the end line at the end point of the runway and the longitudinal central line of the runway so as to realize positive and negative landing of the unmanned aerial vehicle and obtain a high-accuracy runway direction angle. The method disclosed by the invention has the advantages of providing a solution for autonomous take-off and landing as well as positive and negative landing of the unmanned aerial vehicle, conditions for ground control during the take-off and landing of the unmanned aerial vehicle and basis for the high-accuracy calculation of a runway course angle and greatly improving the take-off and landing safety of the unmanned aerial vehicle, along with simple structure and easy realization.

Description

technical field [0001] The invention relates to a method for arranging flight routes of unmanned aerial vehicles, and belongs to the field of route planning of unmanned aerial vehicles. Background technique [0002] Arrival and landing patterns provide specific routes for aircraft takeoff, departure, arrival, and landing. In manned systems, in order to ensure that aircraft enter and leave airports in an orderly manner, it is necessary to establish specific takeoff and landing patterns and traffic control procedures at designated airports, including the direction and structure of takeoff and landing patterns, the altitude of flight, and entry and exit takeoffs and landings Airline procedures. In the current manned flight, the five-sided route is a basic take-off and landing route. Such as figure 1 As shown, when the aircraft is flying on the final route, the pilot controls the aircraft to complete the process of taxiing, liftoff, climbing, turning, straight-line flight, tu...

AI Technical Summary

Problems solved by technology

In view of the safety considerations of the aircraft, it usually takes off against the wind when taking off, and when the drone lands, if it is still in the direction of take-off, it may be in a downwind state, prone to stall, ground speed and other situations, which are extremely unfavorable to flight safety

To sum up, the existing UAV take-off and landing routing methods have certain defects, which are not conducive to flight safety.
