Aircraft Remote Control Rod Centering for Stable Altitude Hold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional remote control systems for aircraft lack automatic return functionality for control rods in the up and down direction, leading to difficulties in maintaining consistent flight altitude and increased operational complexity due to crosstalk with other control rods.
Innovation Solution
Incorporating a spring apparatus or homing device into the control rods to enable automatic return to a preset position after external force removal, ensuring the aircraft maintains a stable flight state by integrating state measurement sensors and feedback loops for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spring apparatus is added to enable automatic return of control rods, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The control rod system is designed to automatically return to its neutral position using a spring apparatus, eliminating the need for manual intervention. The spring stores potential energy when the control rod is displaced and automatically converts it back to neutral position when the external force is removed, making the system self-servicing.
Solution Approach 2:
The control rod system is divided into functional segments: the control rod itself, the spring apparatus for automatic return, and the connection mechanism to the aircraft control surfaces. This segmentation allows each component to be optimized independently while maintaining overall system functionality.
2Stability of the object's composition
If automatic return to center position is implemented, then stability of flight altitude control is improved, but manufacturing complexity increases
Solution Approach 1:
The spring apparatus is pre-loaded and positioned within the control rod assembly during manufacturing, so that the automatic return functionality is built-in from the start. This preliminary configuration ensures that the control rod will automatically return to center position without requiring additional adjustment or assembly steps after installation.
3Loss of time
If control rods automatically return to preset positions, then loss of time for manual adjustment is reduced, but device complexity increases
Solution Approach 1:
The control rod system incorporates a feedback mechanism through the spring apparatus that continuously monitors the position of the control rod and automatically corrects any deviation from the neutral position. When the control rod is displaced, the spring stores energy and automatically returns the rod to center, providing continuous positional feedback and correction without manual intervention.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Simplifies remote control operations by allowing control rods to automatically return to center positions, reducing crosstalk and enhancing the stability of aircraft altitude control, making it easier to maintain consistent flight altitudes without manual fine-tuning.
Implementation Method 1
In some embodiments, the control apparatus further includes a spring apparatus to drive the first control rod to automatically return to the center position after the external force is withdrawn.
Data Source
AI summary
An aircraft control system and control method are disclosed. The system comprises a remote control apparatus with a first control rod and a flight controller associated with an aircraft. The first control rod is configured to move in a first movement direction to control a motion of the aircraft in a first motion direction when an external force is applied on the first control rod and after a withdrawal of the external force, the first control rod returns to a preset position. The remote control apparatus operates to generate one or more control signals corresponding to the withdrawal of the external force. The flight controller controls the aircraft to maintain a flight state based on said control signals and one or more state signals, which are generated based on a measurement of the flight state by a flight controller associated with the aircraft state measurement sensors carried by the aircraft.
