Two-Axis Thrust Vectoring Assembly for Compact 360° Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing propulsion systems, such as conventional ducted fan systems, are limited by their ability to rotate and vector only about a single axis, resulting in low maneuverability and high energy consumption, restricting the variety of vehicle maneuvers.
Innovation Solution
The 360° Advanced Rotation System (ARS) enables two-plane rotation using a universal support assembly with articulated levers and transmission discs, allowing for independent movement and reducing weight, with a compact form factor, and can be integrated with ducted fan propulsion systems for enhanced maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed arm with single-axis articulation is used in conventional propulsion systems, then the structure is simple and easy to manufacture, but the system can rotate and vector about only a single axis, resulting in limited maneuverability
Solution Approach 1:
The propulsion system is divided into multiple articulated segments: a first articulated arm providing first-degree freedom rotation, and a second articulated arm providing second-degree freedom rotation. Each segment handles a specific rotation axis, allowing the system to achieve complex multi-axis maneuverability while keeping individual components relatively simple and manageable.
Solution Approach 2:
The system transitions from single-axis rotation to two-axis rotation by adding a second articulated arm that rotates about an axis different from the first arm's axis. This dimensional expansion enables the propulsion system to vector thrust in multiple directions, dramatically improving adaptability and maneuverability.
2Use of energy by moving object
If a conventional single-axis propulsion system is used, then the device complexity is low, but the energy consumption is high due to low maneuverability requiring higher thrust for repositioning
Solution Approach 1:
The system uses dynamic articulated arms that can actively adjust the propulsion system's orientation in real-time. This dynamic adaptability allows the system to optimize thrust direction continuously, improving maneuverability while reducing the energy required for repositioning compared to static single-axis systems.
3Adaptability or versatility
If articulated arms with multiple degrees of freedom are added to improve maneuverability, then the system can rotate about multiple axes, but the weight increases and the form factor becomes less compact
Solution Approach 1:
By segmenting the rotation functionality into two separate articulated arms, each handling one degree of freedom, the system achieves multi-axis maneuverability without requiring a single complex heavy mechanism. The segmented approach distributes the mechanical load and allows for more efficient use of materials.
Solution Approach 2:
The articulated arms are designed to be lightweight yet sufficiently strong through dynamic structural optimization. The arms can be made from composite materials or hollow structures that maintain strength while reducing weight, enabling multi-degree-of-freedom movement without excessive mass penalty.
