Gust Detection Flight Control for High-Altitude Relay Aircraft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radio relay apparatuses in upper airspace face the risk of unstable attitude and potential fall due to sudden strong winds, such as gusts, which can be generated by rapid upward or downward airflow in the upper airspace, posing a challenge for constructing a stable three-dimensional network in next-generation mobile communication systems.
Innovation Solution
A communication relay apparatus equipped with a flight control system that uses Doppler radar to detect strong winds and determines flight control information to reduce the influence of these winds, allowing the apparatus to autonomously or externally control its flight direction, velocity, altitude, and route to avoid adverse wind conditions, thereby preventing falls and maintaining stable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the communication relay apparatus operates in upper airspace to enable three-dimensional networking, then network coverage and capacity are improved, but the apparatus becomes vulnerable to strong winds and gusts that cause unstable attitude and potential falls
Solution Approach 1:
The system performs preliminary detection of strong winds and gusts using Doppler radar before they affect the aircraft. By detecting wind conditions in advance and predicting their impact on flight attitude, the control system can prepare compensatory actions to maintain stability and prevent falls
Solution Approach 2:
The system continuously monitors wind conditions through Doppler radar and feeds this information back to the flight control system. The control means adjusts flight control information based on real-time wind data and predicted attitude changes, creating a closed-loop control system that maintains stability despite varying wind conditions
2Use of energy by moving object
If the aircraft flies in ascending currents to maintain altitude, then energy consumption is reduced, but sudden strong winds generated in upper airspace can still cause unstable attitude
Solution Approach 1:
The system detects strong winds and gusts in advance using Doppler radar before they develop into harmful conditions. By predicting the generation and movement of strong winds, the system can adjust flight control information proactively to counteract their effects while maintaining energy-efficient flight in ascending currents
Solution Approach 2:
The system continuously monitors wind conditions and feeds this information back to adjust flight control in real-time. The control means processes wind detection results and modifies control commands to maintain stable attitude while preserving energy-efficient flight patterns

AI summary
It is prevented that a communication relay apparatus in an upper airspace, which is suitable for constructing a three-dimensional network, falls by a strong wind. A communication relay apparatus is provided with a relay communication station that performs a radio communication with a terminal apparatus, and is capable of flying in an upper airspace by an autonomous control or an external control. This communication relay apparatus includes a flight control section that controls a flight of the communication relay apparatus based on flight control information determined so as to reduce an influence of a strong wind generated around the communication relay apparatus. The flight control information may include information for controlling at least one of a flight direction, velocity, altitude, attitude, flight route and flight pattern of the communication relay apparatus.
