Switchable Rotor Wing Control for Versatile UAV Flight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current UAVs with multiple rotor wing structures are limited to single-direction power provision, restricting their flight capabilities to a single function.
Innovation Solution
The UAV design incorporates a rotor wing structure with a driving module that allows the first power module to switch between level flight and lifting modes, combined with additional power modules and sensors for altitude and speed control, enabling versatile flight control through a controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple rotor wing structures are fixed directly to the UAV body with single-direction power provision, then the structure is simple and easy to manufacture, but the flight capability is limited to a single function
Solution Approach 1:
The rotor wing structure is made dynamically adjustable through a driving module that enables the first power module to switch between level flight mode and lifting mode. This dynamic configuration allows the same structure to perform multiple flight functions without requiring separate fixed structures for each function.
Solution Approach 2:
The rotor wing structure is designed as a multi-functional system where the first power module can provide power in two different directions. By switching between level flight mode and lifting mode, a single rotor wing structure performs both horizontal propulsion and vertical lifting functions, eliminating the need for separate dedicated structures.
2Adaptability or versatility
If rotor wing structures are made multi-functional with mode switching capability, then flight versatility is improved, but the device complexity and number of components increase
Solution Approach 1:
The invention merges the functions of multiple power modules into a single first power module that can operate in different modes. Instead of having separate power modules for level flight and lifting, one power module performs both functions by changing its orientation and power provision direction through the driving module.
Solution Approach 2:
The system uses dynamic mode switching rather than static multi-module configuration. The first power module dynamically adjusts its function through the driving module, allowing the system to achieve multi-functionality without permanently installing multiple separate power modules.
3Adaptability or versatility
If additional power modules are added to enable vertical ascent and hovering, then flight versatility is improved, but the weight of the UAV increases
Solution Approach 1:
The invention combines the vertical lifting function with the horizontal propulsion function in the same first power module. By making the first power module adjustable between different orientations, the system eliminates the need for separate lifting modules or additional power modules that would otherwise be required for vertical flight capabilities.
Solution Approach 2:
The first power module is designed as a universal power source that can provide both horizontal thrust and vertical lift. This multi-functional design eliminates the need for additional dedicated lifting power modules, thereby reducing the overall weight compared to systems that use separate power modules for different flight modes.
