Aircraft Contrail Suppression Using Atmospheric Sensing and Route Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to effectively suppress contrails generated by aircraft, which contribute to climate change and are influenced by atmospheric conditions and contrail formation.
Innovation Solution
Aircraft are equipped with sensing systems to gather atmospheric and contrail information, allowing for real-time or pre-flight contrail suppression measures such as switching to less contrail-prone fuels, altering flight routes, or using contrail suppression additives, facilitated by direct aircraft-to-aircraft communication or ground-based flight planning tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If aircraft continue to use conventional fuels and flight routes, then operational simplicity is maintained, but contrail formation increases causing environmental harm
Solution Approach 1:
The system performs preliminary detection of atmospheric conditions (temperature, humidity, pressure) before the aircraft enters contrail-prone regions. Flight planning tools calculate optimal routes in advance that avoid ice supersaturated regions, and fuel additives are pre-mixed into the fuel system before flight, enabling contrail suppression before contrails actually form.
Solution Approach 2:
The patent introduces intermediary elements including fuel additives (metals, metal compounds, or other substances) that mediate between the exhaust and atmospheric conditions to prevent contrail formation. The system also uses intermediary detection devices (sensors) to measure atmospheric parameters and intermediary communication systems to transmit data between aircraft and ground-based flight planning tools.
2Object-affected harmful factors
If aircraft switch to less contrail-prone fuels or use contrail suppression additives, thencontrail formation is reduced, but fuel cost and operational complexity increase
Solution Approach 1:
The system changes the chemical composition parameters of the fuel by adding specific substances (metals, metal compounds, or other contrail suppression additives) in controlled amounts. The flight planning tool optimizes the mixture ratio of conventional fuel and alternative fuels, or adjusts the dosage of additives, to achieve contrail suppression while minimizing fuel consumption and cost.
Solution Approach 2:
Instead of requiring complete fuel replacement with expensive alternative fuels, the system applies partial action by adding small amounts of contrail suppression additives to conventional fuel, or using blended fuel compositions. This achieves sufficient contrail suppression效果 without the full cost and logistical burden of complete fuel replacement.
3Object-affected harmful factors
If aircraft alter flight routes in real-time to avoid contrail-prone regions, thencontrail formation is suppressed, but flight time and operational efficiency decrease
Solution Approach 1:
The ground-based flight planning tool receives atmospheric data in advance and pre-calculates optimal flight routes that avoid ice supersaturated regions and contrail-prone areas. This preliminary route planning allows aircraft to follow contrail-suppressing paths without real-time route changes, maintaining operational efficiency while achievingcontrail suppression.
Solution Approach 2:
The system implements feedback mechanisms where atmospheric condition data from detection devices is continuously transmitted to flight planning tools, which then adjust or provide alternative flight routes. This feedback loop enables dynamic route optimization that balancescontrail suppression with minimal impact on flight time and operational efficiency.
Data Source
AI summary
A method of contrail suppression. Data is generated with a sensing system onboard a first aircraft during a flight of the first aircraft. The data includes atmospheric information indicative of an atmospheric condition and/or contrail information indicative of a presence or absence of contrails generated by the first aircraft. A second aircraft is operated to perform one or more contrail suppression measures on a basis of the data.
