Aerial Load Mounting Layout to Avoid Propeller Slipstream
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aerial vehicles experience reduced flight efficiency when carrying loads due to tilting and wind interference, leading to potential loss of cargo and balance issues during delivery.
Innovation Solution
An aerial vehicle design featuring a lift generating part, an arm part, a mounting part located behind the center of gravity, and a maintenance mechanism with a counterweight and hinge system that maintains the orientation of the load horizontally, allowing the vehicle to operate efficiently while minimizing interference with the wake region generated by the rotor blades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the mounting part is located behind the center of gravity to maintain load orientation, then the load stability is improved, but the flight efficiency deteriorates due to increased moment of inertia and control complexity
Solution Approach 1:
A counterweight is provided in front of the center of gravity of the aerial vehicle to balance the mounting part located behind the center of gravity. This counterbalancing arrangement maintains load orientation stability while minimizing the negative impact on flight efficiency by reducing the overall moment of inertia and simplifying control requirements.
2Productivity
If the mounting part is positioned to minimize wake region interference, then flight efficiency is improved, but the load orientation control becomes more difficult
Solution Approach 1:
The first connection part acts as an intermediary mechanism between the mounting part and the arm part, specifically designed to maintain the orientation of the mounted object horizontally. This connection part decouples the orientation control function from the position control function, allowing the mounting part to be positioned for optimal wake region clearance while the connection part handles orientation maintenance independently.
3Adaptability or versatility
If the aerial vehicle tilts during forward movement with load, then the load delivery capability is improved, but the flight efficiency deteriorates due to increased drag and instability
Solution Approach 1:
The aerial vehicle employs dynamic control mechanisms including adjustable rotor blade pitch angles and variable speed motors to maintain horizontal flight posture while carrying loads. The maintenance means dynamically adjusts the orientation of the mounting part and counterweight to compensate for any tilting tendencies, ensuring both load delivery capability and flight efficiency are optimized simultaneously.
