Aircraft Load Position Control to Prevent Cable Entanglement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircrafts face risks of propeller blade entanglement and tipping over due to improper positioning of loads during takeoff, as cables connecting the load and aircraft can become entangled by propeller wash or cause the aircraft to tilt.
Innovation Solution
A control method that assesses the relative horizontal position of the aircraft and load before takeoff, prohibiting the aircraft from pulling the load off the bearing surface if the position does not satisfy preset conditions, and adjusting the aircraft's position to ensure safe takeoff.

Engineering Contradiction Analysis
1Productivity
If the aircraft pulls the load away from the bearing surface without position assessment, then the takeoff process can proceed quickly, but the cable may become entangled by propeller blades or cause the aircraft to tip over
Solution Approach 1:
The system performs preliminary position assessment of the load relative to the aircraft before initiating the takeoff process. The control device evaluates whether the load is properly positioned on the bearing surface and determines if the aircraft is correctly aligned above the load. This preliminary check prevents cable entanglement and tipping hazards by ensuring safe positioning conditions are met before the aircraft accelerates for takeoff.
2Reliability
If the aircraft performs position assessment before takeoff, then the safety during takeoff is improved, but the takeoff process time increases
Solution Approach 1:
The control device automatically performs position assessment and determines takeoff eligibility without requiring manual intervention. The system self-evaluates the relative positions of the aircraft and load, checks whether safety conditions are satisfied, and autonomously decides whether to permit takeoff. This automated self-service approach minimizes the time added to the takeoff process while maintaining enhanced safety through comprehensive position verification.

AI summary
A control method, device, aircraft, and storage medium for an aircraft are provided. The method includes: determining position information of the aircraft and position information of a load on a bearing surface; determining whether a horizontal position of the aircraft satisfies a first preset condition based on the position information of the aircraft and the position information of the load; in response to the horizontal position of the aircraft not satisfying the first preset condition, prohibiting the aircraft from pulling the load away from the bearing surface. In this way, the probability of the cable entangling the rotor blade during the process of the aircraft pulling the load away from the bearing surface, and the probability of the load pulling the aircraft and causing it to tip over, can be reduced, thereby ensuring the safety of the aircraft during takeoff.
