Aircraft Emissions Research
Aerodyne Aircraft Emissions Research
Aerodyne Research has a long history measuring the emissions of aircraft and studying how those aviation emissions influence the environment.
As Aerodyne proprietary instruments have been developed and improved over the years, they continue to play an important role in these studies – right up to the present day.
Capabilities
- Develop procedures and techniques for measuring the transient, evolving nature of aircraft exhaust.
- Create numerical models to simulate detailed chemistry and microphysics that are too transient to measure directly.
- Verify and quantify certification data.
Aerodyne Aviation Activities
Intergovernmental Panel
on Climate Change
Studies in the 1990s were used to support the Intergovernmental Panel on Climate Change (IPCC) in their 1999 report on Aviation and the Global Atmosphere, which was part of IPCC’s work that was recognized with a Nobel Peace Prize.
SAE E-31 Committee on Aircraft Engine Gas and Particulate Emissions Measurement
Aerodyne membership in the SAE E-31 Committee on Aircraft Engine Gas and Particulate Emissions Measurement helped to define the regulatory measurement approach for aviation emissions certification measurements throughout the world.
International Civil Aviation Organization
Aerodyne membership in the International Civil Aviation Organization (ICAO) Committee on Aviation Environmental Protection (CAEP) has helped use those certification measurements to define international standards for commercial aviation engine emissions certification.
Field Campaigns
The Aerodyne Mobile Laboratory (AML) or separate instrument packages have been used to develop techniques and procedures for measuring the transient, evolving nature of aircraft exhaust in the extreme temperature and velocity environment of an exhaust plume. Support from NASA, FAA, EPA, and DoD have extended and refined measurement capabilities in campaigns like APEX1-3, AAFEX1-2, and many others, like the recent Boeing EcoDemonstrator campaign with NASA .
EcoDemonstrator 2023
Aerodyne was a key participant in the recent EcoDemonstrator emissions experiments led by Boeing, NASA, and DLR (the German Aerospace Center) in October 2023. The campaign was designed to understand how the use of Sustainable Aviation Fuels (SAFs), which are derived from biofeedstocks and not fossil sources, can affect the emissions from aircraft engines beyond the reductions in CO2 that arise due to the biological sources for the SAF fuel.
