Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft are prone to lightning strikes, leading to varying degrees of damage that can result in increased repair costs and reduced operational efficiency, due to factors like flight frequency, altitude, geographic region, and time of year, without an effective method to predict and mitigate such damage.
Innovation Solution
A system and method for predicting lightning strike damage to aircraft by generating data on dimensions, design features, and electromagnetic density, creating a numeric index that accounts for specific aircraft types and operational factors, using an algorithmic association to provide a Lightning Damage Index (LDI) for potential damage likelihood and location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If aircraft operate with higher flight frequency and in more geographic regions, then operational efficiency and productivity are improved, but exposure to lightning strikes and potential damage increases
Solution Approach 1:
The patent applies preliminary action by creating a lightning damage index before actual lightning strikes occur. The system pre-calculates damage potential by combining aircraft electromagnetic data with operational factors (flight frequency, altitude, geographic region, time period) to predict which aircraft are most vulnerable to lightning damage, allowing operators to take preventive measures or prioritize inspections beforehand
Solution Approach 2:
The patent replaces physical inspection and reactive repair systems with an algorithmic prediction system. Instead of mechanically inspecting aircraft after lightning strikes or relying on random checks, the system uses computational algorithms to calculate damage indices by processing electromagnetic density data and operational parameters, substituting physical trial-and-error inspection with intelligent prediction
2Measurement precision
If comprehensive data collection and analysis systems are implemented to predict lightning damage, then prediction accuracy is improved, but system complexity increases
Solution Approach 1:
The patent applies universality by creating a multi-functional lightning damage index system that simultaneously handles multiple aircraft types, various operational factors (departure frequency, geographic region, altitude, time period), and different data sources (electromagnetic density, dimensions, design features). This single integrated system performs prediction, ranking, and risk assessment functions without requiring separate complex systems for each function
Solution Approach 2:
The patent applies parameter changes by transforming complex operational conditions into standardized numerical parameters. The system converts qualitative factors like geographic region and time period into quantifiable parameters that can be mathematically processed, allowing accurate prediction through parameter manipulation rather than complex structural analysis
3Reliability
If lightning damage prediction system is implemented, then repair costs and operational disruptions are reduced, but initial investment and data processing requirements increase
Solution Approach 1:
The patent applies the taking out principle by extracting only the most critical data elements needed for lightning damage prediction from the vast amount of available aircraft operational data. The system selectively processes electromagnetic density data, key dimensional parameters, and essential operational factors (flight frequency, altitude, geographic region, time period) while ignoring redundant information, minimizing data processing requirements while maintaining prediction accuracy
Solution Approach 2:
The patent applies copying by creating a virtual model of aircraft vulnerability through electromagnetic density data and operational parameters. Instead of physically testing or inspecting aircraft to assess lightning damage risk, the system creates a computational copy or representation of each aircraft's vulnerability profile, allowing prediction without physical intervention or excessive data collection

AI summary
The present disclosure teaches a lightning damage index is that used to predict the propensity of a lightning strike to an aircraft and the degree of damage to the aircraft that the lightning strike will cause. This index can help to obviate operational issues and other losses related to subsequent repairs to the aircraft that are required because of lightning damage. The disclosed method of predicting lightning strike damage to an aircraft involves generating data relating to the aircraft by measuring the dimensions of the aircraft, assessing the design features of the aircraft, and/or obtaining electromagnetic density data associated with regions of the aircraft. The method further involves creating a lightning damage index that provides a numeric representation for predicted lightning strike damage to the aircraft based on the generated data. The numeric representation may be further modified by factors associated with operation of the aircraft.
