Solution Overview
Problem
Conventional helicopter main rotor systems are inefficient in terms of energy use and thrust generation, particularly at low speeds, due to high drag and limited adjustability, which affects their hover efficiency and fuel consumption.
Innovation Solution
A magnetic driven wing system with a circular concentric apparatus and stepper motor, featuring a gimbal with 3° of freedom, allows for sequential magnet energization and variable wing segment thickness, eliminating the need for a central rotor shaft and enhancing thrust generation by optimizing wing movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a conventional main rotor system is used, then the helicopter can generate thrust, but the energy efficiency is poor and fuel consumption is high
Solution Approach 1:
The rotor blade is divided into multiple independent segments that can be individually controlled and adjusted. Each segment can be independently energized by magnets, allowing for optimized thrust distribution across the blade span, improving overall energy efficiency while reducing fuel consumption.
Solution Approach 2:
The rotor system transitions from a static, fixed-pitch design to a dynamic system where blade segments can be actively adjusted during operation. The variable pitch control and sequential magnet energization allow the rotor to adapt to different flight conditions, optimizing energy efficiency across various operating regimes.
2Adaptability or versatility
If a fixed RPM rotor system is used, then the rotor operates at a stable speed, but the adjustability is limited and hover efficiency is reduced
Solution Approach 1:
The system enables variable rotor blade pitch and segment activation, transforming the fixed RPM system into an adaptable configuration that can optimize hover efficiency while maintaining operational reliability through controlled variability.
Solution Approach 2:
The rotor system allows for dynamic changes in blade pitch angle and segment activation patterns, enabling optimization of aerodynamic parameters for different flight phases including hover, thereby improving both adaptability and efficiency.
3Productivity
If a large diameter rotor is used, then more air can be accelerated for better efficiency, but the device complexity increases
Solution Approach 1:
Dividing the rotor blade into segments allows for controlled activation of only the necessary portions, enabling effective thrust generation with reduced overall complexity compared to fully articulated systems.
