GE Aerospace and NASA Enhance Contrail Research Together

GE Aerospace and NASA Collaborate on Innovative Flight Tests

In a groundbreaking partnership, GE Aerospace (NYSE: GE) and NASA are launching a series of unique flight tests aimed at enhancing the industry’s understanding of contrails. These efforts utilize novel testing methods and advanced technologies designed to unravel the complexities of contrail formation and behavior in the atmosphere.

Contrails, formed from ice particles, occur when aircraft soar through cold, humid air, and their persistent nature has been linked to climate warming effects. Through the planned flight tests, both organizations intend to contribute significantly to research dedicated to understanding contrail science and facilitating the development of new technologies capable of minimizing non-CO₂ emissions produced by aircraft.

Innovative Methodologies and Flight Tests

The exciting Contrail Optical Depth Experiment (CODEX) flight tests are scheduled to take place in November. NASA's G-III aircraft will be trailing GE Aerospace's Flying Test Bed to conduct scans of the aircraft's wake utilizing advanced Light Detection and Ranging (LiDAR) technology. This initiative is anticipated to propel NASA’s adoption of LiDAR, enabling the production of three-dimensional images of contrails, ultimately helping scientists better characterize their formation and evolution.

For GE Aerospace, this represents an evolution in operating methods using its 747 Flying Test Bed. It is an essential step in expanding the capabilities ahead of planned flight tests this decade focusing on evaluating the performance of new commercial engine technologies. Advanced designs, including Open Fan technologies and advanced combustion systems, are being explored in collaboration with CFM International's Revolutionary Innovation for Sustainable Engines (RISE) program.

Expert Insights on Flight Tests

Arjan Hegeman, the General Manager of Future of Flight Technology at GE Aerospace, emphasized the significance of this partnership, stating, "GE Aerospace is proud to once again team up with NASA to be at the forefront of innovation. Understanding how contrails form in-flight with the latest detection technology is critical to driving forward innovation. These tests will lend invaluable insights to enhance the next generation of aircraft engine technologies, ushering in improvements in efficiency and emissions reduction."

Long-standing Collaboration for Progress

GE Aerospace and NASA have enjoyed a partnership for over 50 years, actively working together to hasten the introduction of innovative technologies into the aviation sector. Dr. Rich Wahls, who manages NASA's Sustainable Flight National Partnership, remarked on the importance of this collaboration, pointing out that NASA aims to improve its understanding of contrails to inform future operational management strategies that weigh climate impact against economic considerations.

Enhancing Weather Prediction and Contrail Management

In addition to their flight tests, NASA, in coordination with the German Aerospace Center (DLR) and SATAVIA, is set to elevate atmospheric forecasting to determine conditions conducive to contrail generation. DLR's expertise will support forecasts regarding the altitude and composition of areas where contrails might form, aiding in the optimization of the aircraft's pathway into areas of active contrail formation.

Post-flight analysis involving LiDAR observations will help refine contrail prediction models and enhance capabilities in forecasting contrail formation within ice super saturated regions (ISSR). Additionally, learnings from these flights will support SATAVIA's capabilities, which include a service targeting contrail forecasting and management. Earlier this year, Aerospace Carbon Solutions, a segment of GE Aerospace, acquired SATAVIA, allowing for more integrated approaches to emissions management.

Advancements in Sustainable Technology

CFM International's RISE program, introduced in 2021, is among the most ambitious technology demonstration initiatives in aviation, reflecting real progress in sustainable practices after over 250 successful tests. This program is instrumental in developing an array of pioneering technologies, encompassing advanced engine architectures and hybrid electric systems, all aiming for compatibility with 100% Sustainable Aviation Fuel (SAF). The ongoing research is targeting over 20% enhancement in fuel efficiency combined with a similar reduction in CO₂ emissions in comparison to the most efficient commercial engines available today.

GE Aerospace's ongoing commitment to innovation is reflected in its plan to recruit more than 900 engineers in 2024, further emphasizing its dedication to evolve both current aircraft engine systems and future technologies.

What Lies Ahead for GE Aerospace

The collaborative endeavors of GE Aerospace and NASA extend far beyond flight tests for contrails. Their innovation legacy includes the development of hybrid electric engines, compact core compressors, and enhanced turbine technologies. This partnership is paving the way for future breakthroughs that will define the evolution of flight, ensuring safety and efficiency in a changing climate.
