Towbarless Tractor Capture Monitoring for Nose Gear Damage Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Airplanes are often towed by tractors, but nose gear damage during capture operations is difficult to diagnose without image data, making it challenging to determine the cause of damage.
Innovation Solution
A towbarless tractor system with sensors to monitor the capture system, capture visual data, and store or transmit data in response to events such as crashes or improper alignment, featuring a winch assembly to engage and support the nose gear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual monitoring systems are installed on the towbarless tractor to capture and store image data during capture operations, then the ability to diagnose nose gear damage and determine its cause is improved, but the device complexity and cost increase
Solution Approach 1:
The sensor system is pre-installed on the towbarless tractor to continuously capture visual data before, during, and after capture operations. This preliminary action ensures that image data is already available when needed for damage diagnosis, eliminating the need for post-incident data collection and reducing information loss.
Solution Approach 2:
A sensor acts as an intermediary between the capture operation and the damage diagnosis process. The sensor captures visual data that serves as evidence, allowing operators to objectively determine the cause of nose gear damage without relying solely on visual inspection or operator testimony.
2Reliability
If sensors and visual data capture systems are integrated into the towbarless tractor to monitor capture system operations, then operational safety and damage diagnosis capability are improved, but the manufacturing cost and system complexity increase
Solution Approach 1:
The sensor system serves multiple functions: capturing visual data for damage diagnosis, monitoring capture system operations, and providing evidence for incident analysis. This multi-functionality justifies the additional manufacturing cost by delivering multiple benefits from a single system addition.
Solution Approach 2:
The towbarless tractor performs self-monitoring through integrated sensors that automatically capture and store visual data during operations. This self-service capability reduces the need for external monitoring equipment and manual documentation, improving reliability while keeping the system relatively simple.
3Ease of operation
If the towbarless tractor uses a winch assembly with winch strap to engage and support the nose gear, then the ease of operation and capture system functionality are improved, but the risk of nose gear damage due to improper procedures or equipment malfunction increases
Solution Approach 1:
The sensor system provides feedback by capturing visual data that shows whether the winch assembly and winch strap are properly engaged with the nose gear. This feedback allows operators to verify correct operation in real-time, reducing the risk of damage from improper procedures while maintaining ease of operation.
Solution Approach 2:
The sensor system is pre-positioned to monitor the engagement process before damage can occur. By continuously capturing visual data during the capture operation, the system can detect potential issues before they result in nose gear damage, allowing for corrective action.
Data Source
AI summary
A towbarless tractor system includes one or more processing circuits configured to monitor a capture system of a towbarless tractor based on visual data acquired by a sensor on the towbarless tractor, the capture system configured to engage with a nose gear, and store or transmit at least a portion of the visual data acquired by the sensor of the towbarless tractor regarding the capture system in response to an event.
