On-Time Gift Delivery: See GE Aerospace’s AI-Designed, Multi-Modal Jet Engine to Power Santa’s Sleigh
December 11, 2025 | by Todd Alhart
With the winter holiday season in full swing, GE Aerospace is offering Santa Claus its full suite of cutting-edge innovations from advanced propulsion systems, AI-enabled aftermarket services, and even “dust science,” to ensure his Christmas Eve flight delivering gifts remains on-schedule.
As part of this offering, a special team of “Santa’s helpers” from GE Aerospace used AI to design a sleek new sleigh for Santa. Leveraging the world’s most advanced exascale supercomputing tools and generative AI, this team full of holiday cheer created a unique, multi-modal design that contains three different engine modes to help propel Santa’s sleigh, including:
- Santa’s sleigh with a pair of GE Aerospace’s GE9X widebody engines. Built for long haul travel, the GE9X is the world’s most power commercial engine at 134,300 pounds of thrust.
- An ultra-efficient engine mode leveraging the Open Fan design and hybrid electric propulsion system being developed through the *CFM RISE program; and
- A super high speed, dual mode ramjet propulsion system that will allow Santa to hurdle across the skies at hypersonic speeds of Mach 5+, or >4,000 MPH.
“We thought it would be nice to provide Santa’s sleigh with some extra supplemental power to help cover his deliveries around the world faster and more efficiently than ever before,” said Thomas the Elf, North Pole Fleet Support Leader, GE Aerospace. “With our hypersonic dual mode ramjet, it would take Santa just 40 minutes to travel from New York City to London. But while we want to help Santa fly faster, we also want to help him fly more efficiently too and for the long haul. That’s why we’re also outfitting his sleigh with an alternative ‘ultra-efficient’ engine mode that integrates our latest concepts in hybrid electric propulsion and our new Open Fan engine architecture through the RISE program and third mode with our GE9X engines.”
“We’re pulling out all of the stops to ensure Santa has the safest and most seamless journey possible,” Thomas the Elf added. “We even have enlisted a highly diverse team of geologists, chemists, and material characterization experts to create a special magic dust for Santa that enables him to more easily enter and exit homes to enhance on-time gift delivery.”
Dust Science for Santa
Santa is well known for sprinkling magic dust to access chimneys and teleport through doors to place gifts under the tree for all good little boys and girls without being detected. To support this project, GE Aerospace researchers will be leveraging more than a decade’s worth of dust science research being employed to enhance the durability of our jet engines today and drive insights for next generation engine demonstrators like the CFM RISE program.
In the lab, researchers have been able to mimic the properties of dust our engine experience during takeoff from different parts of the world. This, in turn, has enabled GE Aerospace to conduct dust ingestion tests with commercial engines to understand how the degradation of certain parts occurs, and most importantly, inform the right fix to improve their durability against dust and corrosion. For example, GE Aerospace is now deploying a new, improved high pressure turbine (HPT) blade hardware for the CFM LEAP engine that was made possible through the learnings from dust ingestion testing.
24X7, AI-Enabled “On-Sleigh” Fleet Support Services
GE Aerospace’s support for Santa also extends to aftermarket services. GE Aerospace is in the midst of a $1 billion investment to improve its MRO facilities worldwide and another $1 billion in its U.S. factories and supply chain to strengthen manufacturing and increase the use of innovative new parts and materials needed for the future of flight. A major highlight of this commitment is the new Services Technology Acceleration Center (STAC), which opened in the Fall of 2024 to accelerate the company’s effort to more rapidly deploy cutting-edge AI-enabled inspection technologies to improve on-wing and off-wing services. The STAC was recently recognized with a coveted Laureate Award from Aviation Week for excellence in the MRO category.
“Our Fleet and Customer support teams around the world will be on standby just in case Santa’s sleigh needs a quick engine check or tune up,” Thomas the Elf said. “We will be providing predictive engine health monitoring that uses AI to help us forecast an engine’s services needs a few months ahead. If Santa’s sleigh is having an issues, we should have enough lead time to find the right spot to make any needed repairs.”
“We expect this will be a record year for Santa in gift deliveries,” Thomas the Elf concluded. “The freight on board the sleigh will be substantial, but it’s nothing his reindeer, GE Aerospace propulsion systems, and fleet support teams can’t handle. We’ll be ready.”
*RISE is a technology development program of CFM International, a 50-50 joint company between GE Aerospace and Safran Aircraft Engines. It is not a product offered for commercial sale.”
