Resource Efficiency: UltraFan’s Path Towards Less Reliance on Fossil Fuels — The aviation industry heavily relies on fossil fuels, a finite resource with environmental concerns. Here’s how the UltraFan engine contributes to resource efficiency:

Reducing Reliance on Fossil Fuels:

While UltraFan doesn’t eliminate the need for jet fuel entirely, it significantly reduces our dependence on this fossil fuel. Here’s how:

• Improved Fuel Efficiency: As discussed earlier, the 25% reduction in fuel burn translates to a direct decrease in the amount of jet fuel required per flight. This translates to a lower overall demand for this resource.
• Paving the Way for Sustainable Aviation Fuels (SAF): Increased engine efficiency creates a more favorable environment for the adoption of SAF. SAF is a cleaner alternative fuel derived from renewable sources like biomass or recycled materials. With lower fuel consumption, airlines can integrate SAF into their operations more readily, further reducing reliance on traditional jet fuel.

Advanced Materials and Manufacturing for Resource Efficiency:

UltraFan incorporates advancements in materials and manufacturing techniques to achieve both lighter weight and lower fuel burn:
