Aircraft Vertical Stabilizer Lift Propeller Torque Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The aerodynamic profile of drones is negatively affected by the size and shape of motor housings that drive their lifting propellers, leading to increased drag and reduced efficiency in flight.
Innovation Solution
The motor that drives each propeller is discreetly placed within the support arm or wing, eliminating the need for bulky motor housings and allowing for a more streamlined aerodynamic profile by using gears to transmit torque from the motor shaft to the propeller shaft, which can be co-axial or at an angle, minimizing air drag and improving aerodynamics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If motor housings are used to encase the motors that drive propellers, then the motors are protected and easily mounted, but the aerodynamic profile is negatively affected and air drag increases
Solution Approach 1:
The motor housing is extracted and removed from the design. The motor is mounted directly to the support arm or wing structure without an enclosing housing, eliminating the aerodynamic obstruction while maintaining motor functionality and ease of mounting.
2Reliability
If bulky motor housings are used to encase motors, then motor components are protected, but the aerodynamic efficiency is reduced and flight endurance decreases
Solution Approach 1:
The motor housing is removed entirely. The motor is mounted directly to structural components, eliminating the protective housing that caused aerodynamic drag. This reduces energy consumption during flight, thereby extending flight endurance while the motor remains protected through direct mounting to robust support structures.
3Device complexity
If motors are placed directly under propellers within motor housings, then the drive mechanism is simplified, but the aerodynamic profile is compromised
Solution Approach 1:
The motor housing is extracted from the design. The motor is mounted directly to the support arm or wing, with the propeller mounted directly to the motor shaft. This maintains the simplicity of the drive mechanism while eliminating the bulky housing that disrupted the aerodynamic profile.
