Wake Vortex Separation Determination Using Mesh Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air traffic control systems use broad, size-based categories to set wake vortex separation distances, leading to excessive airspace between aircraft, causing inefficiencies and congestion, especially during take-off and landing, as they do not account for specific aircraft characteristics or environmental factors.
Innovation Solution
A system utilizing mesh sensors to detect and measure wake vortex vertical drift, allowing for the determination of a minimum wake separation distance based on real-time data, which updates the separation interval for subsequent aircraft, thereby reducing excess separation distances and improving airspace utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If broad size-based aircraft categories are used to set wake vortex separation distances, then safety is improved by ensuring following aircraft avoid wake vortices, but excessive airspace between aircraft is created reducing efficiency
Solution Approach 1:
The patent transitions from fixed size-based categories to dynamic separation distances that change based on real-time parameters including actual wake vortex drift measurements, aircraft weight, and environmental conditions. This allows the separation distance to be optimized for each specific situation rather than using blanket categories.
Solution Approach 2:
The system implements feedback by using mesh sensors to detect actual wake vortex positions and drift patterns, then using this information to adjust separation distances for subsequent aircraft. This closed-loop approach continuously refines separation based on observed wake behavior rather than relying on predetermined categories.
2Reliability
If increased separation distances are used between aircraft, then wake vortex avoidance is ensured, but congestion and delay increase on the ground and in airspace
Solution Approach 1:
The patent makes the separation distance dynamic rather than static, adjusting it in real-time based on actual wake vortex drift measurements and environmental conditions. This allows separation to be minimized when safe and increased only when necessary, rather than maintaining consistently large buffers.
Solution Approach 2:
The system performs preliminary measurements of wake vortex drift using mesh sensors before determining the appropriate separation distance for the next aircraft. This advance knowledge allows for optimized separation decisions that prevent both excessive waiting and unsafe following.
3Device complexity
If broad category-based separation is used, then simplicity in air traffic control is maintained, but measurement precision of actual wake vortex drift is insufficient
Solution Approach 1:
The patent introduces mesh sensors as intermediary devices that directly measure wake vortex drift and provide precise data to the air traffic control system. This intermediary layer handles the complexity of precise measurement, allowing the overall system to maintain simplicity while achieving high measurement accuracy.
Solution Approach 2:
The system replaces the mechanical/category-based estimation approach with electronic sensing and digital measurement using mesh sensors. This substitution enables precise, real-time measurement of wake vortex drift without requiring complex manual assessment procedures.
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
This approach reduces congestion and increases airport throughput by providing more accurate wake vortex separation distances tailored to specific aircraft and environmental conditions, enhancing both safety and efficiency in controlled flight corridors.
Implementation Method 1
Aircraft create areas of air turbulence in the airspace around the aircraft and in the wake of the aircraft during flight. Wake vortices, commonly referred to as a wake vortex and/or wake vortex turbulence, are one source of air turbulence in the wake of the aircraft in flight.
Data Source
AI summary
Techniques for updating wake separation distance between aircraft are described. A sensors mesh within a flight path of an aircraft is used to detect when a wake vortex from the aircraft has drifted onto the sensor mesh. A minimum wake separation distance and separation interval for following aircraft are determined based on the various sensor measurements, environmental conditions, and aircraft properties. The minimum wake separation distance and separation interval are used to minimize aircraft separation distances between aircraft that are required due to wake vortex turbulence caused by aircraft during flight.
