Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional moving body group control method is used, then calculation is simplified by using particle method, but control reliability deteriorates due to ignoring real airspace factors like turbulence and wake turbulence
Solution Approach 1:
The system performs preliminary estimation of wake turbulence and surrounding turbulence before aircraft flight operations. By calculating turbulence parameters in advance based on aircraft specifications and operational data, the system prepares control information that accounts for real airspace factors, thereby improving control reliability without significantly increasing operational complexity.
Solution Approach 2:
The invention introduces an intermediary turbulence estimation system that acts between the aircraft and the control system. This intermediary component processes aircraft specification information and operational data to generate turbulence estimates, which then inform the control decisions. This mediator approach allows conventional simple control methods to be enhanced with realistic turbulence considerations.
2Reliability
If real-time turbulence estimation is implemented, then flight safety is improved, but system complexity increases due to additional calculation requirements
Solution Approach 1:
The system uses copying by creating simplified models of turbulence based on aircraft specification information and operational data. Instead of performing complex real-time fluid dynamics calculations, the system generates representative turbulence parameter copies that capture essential characteristics. This approach maintains flight safety while avoiding excessive computational complexity.
Solution Approach 2:
The invention implements parameter changes by transitioning from detailed physical models to simplified turbulence parameter representations. The system estimates key turbulence parameters (such as intensity and spatial distribution) based on aircraft specifications and operational conditions, changing the representation from complex continuous fields to discrete actionable parameters that can be processed by conventional control systems.
3Speed
If conventional particle method is used, then computational speed is maintained, but information accuracy deteriorates due to pseudo turbulence generation
Solution Approach 1:
The system performs preliminary turbulence estimation using aircraft specification information before flight operations begin. By calculating turbulence parameters in advance based on known aircraft characteristics and operational data, the system prepares accurate turbulence information without requiring complex real-time calculations during flight, thus maintaining computational speed while improving accuracy.
Solution Approach 2:
The invention implements feedback by using actual aircraft operational data to refine turbulence estimates. The system continuously updates turbulence parameter calculations based on feedback from aircraft performance data and environmental conditions, improving the accuracy of turbulence information while maintaining efficient calculation through iterative refinement rather than complex modeling.
