Drone Takeoff Control System for Windy Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flying object takeoff control systems require an angle changeable helipad to ensure smooth takeoff in windy conditions, which complicates the heliport design and increases costs.
Innovation Solution
A flying object takeoff control system that includes a wind speed and wind direction acquisition unit, a target attitude calculation unit, and a rotor control unit, allowing the flying object to adjust its attitude independently to compensate for wind conditions without needing an angle changing function on the helipad, using lock mechanisms and attitude detection for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an angle changeable helipad is provided to enable smooth takeoff in windy conditions, then takeoff performance is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
Instead of changing the helipad angle to adapt to wind conditions, the invention inverts the approach by keeping the helipad fixed and changing the flying object's attitude (rolling the multicopter body) to adapt to the wind. This transfers the complexity from the heliport infrastructure to the flying object's control system, resolving the contradiction between takeoff performance and heliport complexity.
Solution Approach 2:
The flying object performs self-adjustment of its attitude using its own control system and actuators to compensate for wind conditions. The multicopter independently calculates the required attitude adjustment based on wind speed and direction, then executes the adjustment through its rotor control system, eliminating the need for external heliport angle adjustment mechanisms.
2Reliability
If an angle changeable helipad is provided to enable smooth takeoff in windy conditions, then takeoff performance is improved, but manufacturing costs increase
Solution Approach 1:
The invention reverses which system needs to be complex and expensive: instead of making the helipad angle-adjustable (which would require complex mechanical structures and high manufacturing costs), it makes the flying object's attitude-adjustable using its existing control systems, significantly reducing manufacturing costs while maintaining takeoff performance.
Solution Approach 2:
The flying object's control system, which already exists for normal flight control, is made multi-functional by also using it for wind compensation and attitude adjustment during takeoff. This eliminates the need for separate angle adjustment mechanisms, reducing manufacturing costs while maintaining the ability to handle windy conditions.
3Device complexity
If the flying object adjusts its attitude independently using rotor control, then heliport complexity is reduced, but control precision requirements increase
Solution Approach 1:
The system uses feedback from wind speed and direction sensors to continuously monitor environmental conditions, and feedback from attitude sensors (such as gyroscopes and accelerometers) to monitor the flying object's actual attitude. The control system processes this feedback information and continuously adjusts rotor speeds to maintain the target attitude, ensuring precise control despite the increased requirements.
Solution Approach 2:
The invention replaces mechanical angle adjustment mechanisms with electronic control of the rotors. By using electronic sensors and computer control to adjust rotor speeds independently, the system achieves precise attitude control without mechanical linkages, reducing heliport complexity while meeting precision requirements through electronic feedback control.
4Stability of the object's composition
If lock mechanisms are used to secure the flying object to the helipad, then stability during attitude adjustment is improved, but device complexity increases
Solution Approach 1:
The locking system is segmented into multiple independent lock mechanisms (first and second lock mechanisms) that can operate independently. This allows selective locking of different parts of the flying object, providing stability during attitude adjustment while keeping each individual lock mechanism relatively simple in design.
Solution Approach 2:
The lock mechanisms are designed to be dynamic rather than static - they can be locked and unlocked as needed during the takeoff process. The system transitions from a locked state (when the flying object is on the helipad) to an unlocked state (when taking off), providing stability only when needed and reducing complexity by not requiring permanent fixed structures.

AI summary
A flight controller of a drone calculates a target attitude of the drone on a port based on the result of acquisition by an anemometer. The flight controller of the drone controls each of a plurality of rotors independently, and controls each of the rotors so as to make the drone on the port take a target attitude.
