Drone Rotor Output Balancing for Off-Center Cargo Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aircrafts face stability issues during flight when loaded with freight, particularly when the center of gravity of the aircraft and the freight do not match, leading to tilting and instability.
Innovation Solution
The unmanned aircraft is equipped with at least two generators with rotor blades that generate airflow, a sensor to detect tilt, and a processor that adjusts the output forces of the generators based on detected tilt and positional relationships to maintain stability, determining reference values for balanced flight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the unmanned aircraft is loaded with freight, then the cargo carrying capacity is improved, but the flight stability deteriorates when the center of gravity does not match
Solution Approach 1:
The system dynamically changes the output force parameters of individual generators based on detected tilt conditions. When tilt exceeds thresholds, the processor adjusts the output force of specific generators to counteract the tilt, enabling stable flight with mismatched center of gravity and allowing flexible cargo loading configurations
2Adaptability or versatility
If the center of gravity of the unmanned aircraft and the freight do not match in horizontal direction, then the cargo loading flexibility is improved, but the ability to maintain horizontal attitude deteriorates
Solution Approach 1:
The system applies differential output force control to individual generators based on their positional relationships with the center of gravity. Each generator's output force is independently adjusted according to local tilt conditions and positional parameters, enabling the aircraft to maintain horizontal attitude even with asymmetric cargo loading
3Stability of the object's composition
If individual generators are operated to adjust output forces, then the flight stability is improved, but the control complexity increases
Solution Approach 1:
The system uses sensor feedback to detect tilt conditions and automatically adjusts generator output forces accordingly. The processor continuously monitors tilt thresholds and modulates generator output in response to detected conditions, providing stable flight control through automated feedback mechanisms rather than complex manual control

Function Achieved in This Case
Enables stable flight even when the aircraft is loaded with freight by individually adjusting the output forces of the generators to balance the tilt and center of gravity, preventing tilting and ensuring horizontal attitude in hovering.

AI summary
An unmanned aircraft includes: at least two generators generating forces to fly the unmanned aircraft, each including a rotor blade generating an airflow; a sensor detecting a tilt of the unmanned aircraft; and a processor controlling the generators to control flight of the unmanned aircraft. The processor: obtains an output force adjustment trigger for the generators; obtaining the trigger, causes each generator to individually operate at least until the tilt of the unmanned aircraft detected by the sensor satisfies a predetermined condition; determines a reference value related to an output force of each generator from a value related to the output force of each generator when the tilt of the unmanned aircraft satisfies the predetermined condition and a positional relationship between the generators; and controls the flight of the unmanned aircraft, using the reference values determined.
