Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining aircraft emissions fail to account for engine deterioration and variations in emissions at different power levels, leading to inaccurate estimates that do not reflect the actual emissions produced during a flight mission.
Innovation Solution
A system and method that utilizes an engine cycle model and service data to estimate emissions by projecting emissions at different power levels, considering engine deterioration, and providing an emission index that is tailored to the specific aircraft or fleet, enabling real-time monitoring and management of emissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing methods are used to determine aircraft emissions, then the process is simple, but the accuracy of emission estimates is poor because they fail to account for engine deterioration and power level variations
Solution Approach 1:
The emission estimation process is segmented into multiple discrete steps: receiving service flight data, projecting control data input to different power levels, generating emission index, and determining total emissions. This segmentation allows each step to be optimized independently while maintaining overall system manageability.
Solution Approach 2:
The system performs preliminary projection of control data input to different power levels before generating the final emission index. This preliminary action accounts for engine deterioration and power level variations in advance, improving accuracy without requiring complex real-time adjustments during emission calculation.
2Reliability
If existing methods are used to determine aircraft emissions, then the system is simple to operate, but the reliability of emission data is poor due to lack of consideration for engine deterioration
Solution Approach 1:
The system incorporates service flight data as feedback to continuously update and refine emission estimates. This feedback mechanism accounts for engine deterioration over time by using actual operational data, improving reliability while maintaining ease of operation through automated data collection and processing.
Solution Approach 2:
The system changes key parameters including power levels and service flight data to generate more accurate emission estimates. By varying these parameters and observing their impact on emissions, the system reliably captures engine deterioration effects without complicating operation.
3Measurement precision
If detailed emission tracking is implemented to account for engine deterioration and power levels, then emission estimate accuracy improves, but the time required for calculation increases
Solution Approach 1:
The system performs preliminary projection of control data to different power levels before final emission calculation. This preliminary action pre-processes data to account for engine deterioration and power variations, enabling accurate emission estimates to be generated quickly without extensive real-time computation.
