Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flapping rotor aircrafts experience reduced lifting efficiency due to partial lift cancellation during uplink and downlink actions, and unstable lifts caused by 360-degree rotation of rotor planes, which negatively impact lift generation.
Innovation Solution
A flapping rotor device with uplink vertical rotation and downlink horizontal rotation, symmetrically arranged at the two sides of a fuselage, featuring a unique arrangement of revolution main shafts, servo motors, and rotor devices that control the rotation planes of the rotors to remain vertical and horizontal alternately, avoiding mutual resistance and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the rotors keep rotating during uplink and downlink process, then the flapping rotor device can maintain continuous rotation, but the rotation planes rotate 360 degrees producing unstable lifts
Solution Approach 1:
The patent applies dynamics by making the rotor rotation plane adjustable rather than fixed. The rotation plane can dynamically change between horizontal and vertical positions during the uplink and downlink processes, allowing the system to adapt its configuration to maintain both continuous rotation and stable lift generation.
2Speed
If the rotors rotate 360 degrees, then the flapping rotor device can complete full rotation cycles, but the rotation planes negatively impact the lift
Solution Approach 1:
The patent implements periodic action by alternating the rotor rotation planes between horizontal and vertical positions in a cyclical manner. During uplink process, one rotor maintains horizontal rotation plane while the other is vertical, and this configuration periodically switches during downlink, ensuring that at least one rotor continuously generates effective lift while both complete full rotation cycles.
3Adaptability or versatility
If the flapping rotor devices execute uplink and downlink actions, then the aircraft can perform vertical maneuvers, but partial lift is cancelled reducing lifting efficiency
Solution Approach 1:
The patent applies asymmetry by configuring the two rotors with different rotation plane orientations during uplink and downlink processes. Instead of both rotors having identical orientations, one rotor's rotation plane is horizontal while the other is vertical, creating an asymmetric configuration that prevents lift cancellation and maintains high lifting efficiency during vertical maneuvers.
