Electric Aircraft Elevator Control for Stable Pitch Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Controlling an electric aircraft's pitch against airflow during flight is challenging, and existing solutions are insufficient.
Innovation Solution
An electric aircraft system with pitch control using an elevator, where a flight controller receives a lift command from a lift lever and adjusts the elevator accordingly, enabling precise control of pitch through deflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If an elevator is used for pitch control in an electric aircraft, then the aircraft's stability and maneuverability are improved, but the device complexity increases due to the need for a flight controller and lift lever integration
Solution Approach 1:
The patent combines the lift lever, flight controller, and elevator into an integrated pitch control system. The flight controller serves as a central hub that receives inputs from the lift lever and automatically adjusts the elevator position, merging multiple control functions into a unified system that improves stability while managing complexity through integration.
Solution Approach 2:
The flight controller acts as an intermediary between the pilot's input on the lift lever and the elevator's response. It processes the lift command, calculates appropriate elevator deflection, and sends control signals to the elevator actuators, thereby mediating the control process to achieve stable and precise pitch control.
2Ease of operation
If the elevator is adjusted frequently for precise pitch control, then the maneuverability is improved, but the loss of time occurs due to continuous control adjustments
Solution Approach 1:
The flight controller continuously monitors the lift lever position and automatically adjusts the elevator in real-time to maintain precise pitch control. This continuous automatic adjustment eliminates the need for discrete manual corrections, providing smooth and continuous pitch control that improves maneuverability without significant time loss.
Solution Approach 2:
The system performs self-service by automatically processing pilot inputs and executing elevator adjustments without requiring manual intervention for each control action. The flight controller autonomously calculates and implements the necessary elevator deflection based on lift lever position, reducing the time and effort required for pitch control maneuvers.
