Description

Flight path setting system for optimizing aircraft direction changes and path setting method therefor The embodiments disclosed in this specification relate to a flight path setting system and a path setting method for optimizing the direction change of an aircraft. Urban Air Mobility (UAM) refers to aerial transportation within cities. UAM is highly technologically advanced, and the latest technology is applied to flight path planning. UAM operators can manually input flight paths or generate them automatically through the flight path planning system. This system calculates the optimal route by considering the UAM's current location, destination, flight speed, atmospheric conditions, and other factors. In the flight path planning system, location-based systems such as GPS and various sensors installed inside the UAM detect the flight path and automatically adjust it. Accordingly, the flight path planning system enables the maximization of flight safety and efficiency using minimal human resources. The flight path planning of UAMs is also connected to air traffic and spatial segmentation systems. This is essential for sharing space with other UAMs and simultaneously managing altitudes and routes. However, there is a need to further optimize the flight path planning of aircraft, including these UAMs. FIG. 1 is a configuration diagram of a flight path setting system for optimizing the direction change of an aircraft according to one embodiment. FIG. 2 is a configuration diagram of a flight path setting device according to one embodiment. Figure 3 is an explanatory diagram of the first waypoint. Figure 4 is an explanatory diagram of the angle change adjustment value. Figure 5 is an explanatory diagram of a secondary waypoint. FIG. 6 is a flowchart of a flight path setting method according to one embodiment. Hereinafter, a flight path setting system and a method for optimizing the direction change of an aircraft according to embodiments of the present disclosure will be described in detail with reference to the attached drawings. It should be understood that the following embodiments of the present disclosure are merely for the purpose of embodying the present disclosure and do not limit or restrict the scope of the rights of the present disclosure. Anything that can be easily inferred by a person skilled in the art to which the present disclosure pertains from the detailed description and embodiments of the present disclosure is interpreted as falling within the scope of the rights of the present disclosure. First, FIG. 1 shows a configuration diagram of a flight path setting system (100) for optimizing the direction change of an aircraft according to one embodiment. As can be seen from FIG. 1, a flight path setting system (100) according to one embodiment is configured to include an environment data measuring unit (10) and a flight path setting device (20). The environmental data measuring unit (10) is responsible for measuring at least one environmental data. Each of the at least one environmental data is data regarding environmental factors that affect the flight path setting of the aircraft. The at least one environmental data may include location information signal strength, the quality of communication signals by a mobile communication network, weather information, and real-time traffic condition information. A communication signal by a mobile communication network may include at least one signal from various generations of mobile communication technologies such as LTE, 2G, 3G, 4G, and 5G. An example of a location information signal is a GNSS (Global Navigation Satellite System) signal. Alternatively, the location information signal may be a GPS (Global Positioning System) signal, a Galileo signal, a GLONASS signal, or a BeiDou signal included in a GNSS signal. At least one environmental data may be measured by the environmental data measuring unit (10) and stored in advance in the flight path setting device (20). Additionally, it may be updated by the environmental data measuring unit (10) even during the flight of the aircraft. The flight path setting device (20) acquires environmental data measured by the environmental data measuring unit (10) and sets a flight path, and can be described as a server. The flight path set by the flight path setting device (20) needs to be transmitted to a terminal equipped on the aircraft. However, the flight path setting device (20) may, in some cases, be a terminal equipped on each aircraft rather than a server. In addition, the flight path setting device (20) is a type of computing device. FIG. 2 is a configuration diagram of a flight path setting device (20) according to one embodiment. As can be seen from FIG. 2, the flight path setting device (20) may be configured to include at least one processor (P), a memory (M), and a communication device (C). The memory (M) contains instructions executable by at least one processor (P), and at least one processor (P) execute
