Los motores de aeronaves son una fuente importante de emisiones de óxido de nitrógeno (NOx) y contribuyen a la contaminación del aire y la degradación ambiental. Como resultado, los fabricantes de aviones han desarrollado tecnologías avanzadas para reducir las emisiones, incluido el uso de sensores de NOx.
Los sensores de NOx utilizados en los motores de aviones funcionan de manera similar a los utilizados en otras fuentes de combustión. Monitorean continuamente los niveles de emisiones de NOx en los gases de escape y envían las lecturas al sistema de control del motor. Luego, el sistema de control del motor ajusta la inyección de combustible, la relación aire-combustible y otros parámetros de combustión para reducir las emisiones de NOx.
Un desafío clave en el desarrollo de sensores de NOx para motores de aviones es la necesidad de hacerlos livianos, robustos y confiables, ya que deben operar en condiciones extremas de temperatura, presión y vibración. Los fabricantes han desarrollado sensores de NOx utilizando materiales y tecnología avanzados, como cerámica, películas delgadas y resonancia de plasmón superficial.
El uso de sensores de NOx en los motores de los aviones es cada vez más obligatorio, ya que las normativas exigen que los fabricantes de aviones cumplan normas estrictas sobre emisiones. Estos sensores permiten a los fabricantes de aviones garantizar que sus motores cumplan con estas regulaciones y reducir el impacto ambiental de los viajes aéreos.

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.
