UAV Wind-Aware Flight Control Using a Scout Drone
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UAV flight control systems are delayed in responding to changes in wind, leading to instability and potential loss of balance or crash.
Innovation Solution
A system where a second UAV provides real-time wind information to a first UAV, allowing for immediate adjustments in flight control, including switching between flight modes based on wind data and positional relationships.

Engineering Contradiction Analysis
1Reliability
If the UAV uses modeled acceleration and actual acceleration to estimate wind speed and control trajectory, then the UAV can compensate for trajectory deviations due to wind, but the flight control response to wind changes is delayed
Solution Approach 1:
The patent deploys a second UAV to fly ahead of the first UAV and detect wind conditions in advance. This preliminary detection allows the first UAV to receive wind information before actually encountering the wind changes, enabling proactive trajectory adjustment rather than reactive compensation, thus reducing the response delay while maintaining control stability
Solution Approach 2:
The second UAV acts as an intermediary between the wind environment and the first UAV. It detects wind conditions and transmits this information to the first UAV, serving as a mediator that bridges the gap between the actual wind conditions and the first UAV's flight path, allowing the first UAV to anticipate and prepare for wind changes

AI summary
An unmanned aerial vehicle (UAV) control system includes a first UAV, a second UAV that flies near the first UAV during a flight of the first UAV and is configured to obtain wind information about wind, and flight control means for controlling the flight of the first UAV based on the wind information obtained by the second UAV.
