Solution Overview

Problem

Current flight management systems face challenges in determining optimal flight paths that avoid weather vortices while utilizing vortex currents to minimize flight time and fuel consumption, often resulting in increased travel time and costs due to pilot judgment errors and inefficient navigation.

Innovation Solution

A controller system that determines flight paths by receiving input parameters such as starting and ending points, current aircraft speed, wind vortex strength, and position, and uses boundary value optimization techniques based on differential equations and Lagrangian multipliers to calculate optimal flight paths and control variables, minimizing time and fuel consumption by strategically using vortex currents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the flight path avoids storm cells altogether, then aircraft safety is improved, but flight time increases

Engineering Contradiction:
Improveaircraft safetyVSAvoidflight time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system applies partial action by allowing the aircraft to partially enter the vortex region to capture beneficial tailwinds, rather than completely avoiding the storm cell. The optimization algorithm calculates the precise boundary where the benefits of wind assistance outweigh the risks of vortex exposure, enabling the aircraft to take advantage of strong tailwinds on the periphery of storm cells without venturing into dangerous core regions.

Inventive Principle:
Principle #16Partial or excessive action

2Loss of time

If the aircraft flies close to the eye of a vortex to catch tailwinds, then flight time decreases, but cross winds increase causing additional fuel consumption

Engineering Contradiction:
Improveflight timeVSAvoidfuel consumption
Core Design Contradiction:
Loss of timeVSUse of energy by moving object

Solution Approach 1:

The system dynamically changes the parameter of flight path distance from the vortex center based on real-time conditions. The optimization algorithm continuously adjusts the radial distance parameter to find the optimal balance point where tailwind benefits are maximized while crosswind penalties are minimized. This involves calculating the gradient of wind field parameters and adjusting the flight path accordingly to operate at the optimal distance from the vortex center.

Inventive Principle:
Principle #35Parameter changes

3Use of energy by moving object

If the aircraft flies far from the eye of the vortex, then cross winds are reduced, but the aircraft misses stronger tailwinds and flight time increases

Engineering Contradiction:
Improvefuel consumptionVSAvoidflight time
Core Design Contradiction:
Use of energy by moving objectVSLoss of time

Solution Approach 1:

The system converts the harmful vortex structure into a beneficial resource by strategically positioning the aircraft to exploit the vortex's peripheral tailwinds. The optimization algorithm identifies regions where the vortex structure creates favorable wind patterns that can be harnessed to reduce flight time, transforming what would normally be a purely hazardous weather feature into a potential performance advantage when approached from the correct direction and distance.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

4Adaptability or versatility

If pilots use judgment to determine routes avoiding storm cells, then flexibility is maintained, but error probability increases resulting in significant course deviation

Engineering Contradiction:
Improveroute flexibilityVSAvoidnavigation accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system implements continuous feedback by monitoring aircraft position, wind field conditions, and vortex parameters in real-time. The optimization algorithm uses this feedback to dynamically adjust the flight path, ensuring the aircraft remains on the optimal trajectory. This closed-loop control maintains high navigation precision while preserving route flexibility, as the system can adapt to changing conditions but always guides the aircraft back toward the calculated optimal path.

Inventive Principle:
Principle #23Feedback
