Flugzeugtriebwerke sind eine erhebliche Quelle von Stickoxid-Emissionen (NOx) und tragen zur Luftverschmutzung und Umweltzerstörung bei. Infolgedessen haben Flugzeughersteller fortschrittliche Technologien zur Emissionsreduzierung entwickelt, einschließlich der Verwendung von NOx-Sensoren.
In Flugzeugtriebwerken verwendete NOx-Sensoren funktionieren auf ähnliche Weise wie diejenigen, die in anderen Verbrennungsquellen verwendet werden. Sie überwachen kontinuierlich die NOx-Emissionen in den Abgasen und übermitteln die Messwerte an die Motorsteuerung. Das Motorsteuerungssystem passt dann die Kraftstoffeinspritzung, das Luft-Kraftstoff-Verhältnis und andere Verbrennungsparameter an, um die NOx-Emissionen zu reduzieren.
Eine zentrale Herausforderung bei der Entwicklung von NOx-Sensoren für Flugzeugtriebwerke besteht darin, sie leicht, robust und zuverlässig zu machen, da sie unter extremen Temperatur-, Druck- und Vibrationsbedingungen arbeiten müssen. Hersteller haben NOx-Sensoren entwickelt, die fortschrittliche Materialien und Technologien wie Keramik, dünne Filme und Oberflächenplasmonenresonanz nutzen.
Der Einsatz von NOx-Sensoren in Flugzeugtriebwerken wird zunehmend verpflichtend, da Flugzeughersteller aufgrund von Vorschriften strenge Emissionsstandards einhalten müssen. Mit diesen Sensoren können Flugzeughersteller sicherstellen, dass ihre Triebwerke diese Vorschriften einhalten und die Umweltauswirkungen von Flugreisen verringern.

Aircraft Engine Types and NOx Requirements
Aircraft engines present unique challenges for NOx sensor technology due to the extreme operating conditions, including high altitudes, temperature variations, and the need for absolute reliability. Modern aviation requires precise emission monitoring to meet stringent environmental regulations.
Turbofan Engines
Turbofan engines used in commercial and military aircraft require NOx monitoring at the exhaust. Modern turbofan designs focus on lean-burn combustion to reduce NOx formation. Our sensors are calibrated for the high-temperature, high-velocity exhaust streams typical of turbofan operations.
Turboprop Engines
Turboprop engines, common in regional aircraft and military transports, operate at different power settings than turbofans. NOx sensors for turboprop applications must be responsive across a wider range of operating conditions while maintaining accuracy at lower exhaust temperatures.
Helicopter Turboshafts
Turboshaft engines used in helicopters face unique vibration profiles and rapid power changes. Our aviation-grade NOx sensors are designed to withstand these conditions while providing accurate readings during dynamic flight operations.
Auxiliary Power Units (APUs)
APUs generate electrical power and bleed air while aircraft are on the ground. APU emission monitoring is increasingly important as airports face stricter environmental regulations. Our sensors are suitable for APU exhaust monitoring applications.
Aviation NOx Regulations
The International Civil Aviation Organization (ICAO) sets NOx emission standards for aircraft engines through its Committee on Aviation Environmental Protection (CAEP). These standards have become progressively stricter:
- CAEP/2 Standards — Baseline NOx limits established in 1996
- CAEP/4 Standards — 12% reduction in NOx limits
- CAEP/6 Standards — Further 15% reduction applied to new engine types
- CAEP/8 Standards — Additional 10% NOx reduction requirements
- CAEP/10 Standards — Most recent and most stringent NOx limits
Accurate NOx measurement is essential for engine manufacturers to certify compliance with these evolving standards. Our aviation-grade sensors provide the precision and reliability required for this critical application.
Specific Applications
Emission Testing
Engine certification and compliance testing require precise NOx measurement across the entire operating envelope.
Engine Health Monitoring
Changes in NOx output can indicate combustion chamber wear, fuel injector problems, or other maintenance issues.
Research & Development
New engine designs require extensive NOx monitoring during development to optimize combustion for lower emissions.
Ground Support Equipment
Aviation ground equipment with diesel engines also requires NOx monitoring, and our sensors are suitable for these applications.
