Solution Overview

Problem

Modern aircraft with stationary rotors during edgewise flight experience increased air resistance and drag, which hinders efficiency and energy optimization.

Innovation Solution

A computing device determines a drag minimization axis for a rotor and sends a halting command to a magnetic element to position the rotor in a way that minimizes drag, with the first end pointing in one direction of the axis and the second end in the opposite direction, allowing the rotor to halt and reduce air resistance during flight.

1Device complexity

If the rotor remains stationary during edgewise flight, then the aircraft structure can be simplified, but air resistance and drag increase

Engineering Contradiction:

Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The rotor is designed to transition from a stationary state during vertical flight to a rotating state during edgewise flight. The rotor spins horizontally during edgewise flight to reduce drag, and returns to stationary position during vertical flight phases, making the system dynamically adaptive to different flight modes

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rotor's operational parameters (rotation speed, orientation) are changed based on flight phase. During edgewise flight, the rotor rotates at optimized speeds with horizontal orientation to minimize drag, while during vertical flight, it transitions to a stationary vertical orientation, optimizing performance for each operational state
