Abstract:

This report summarizes the results of the first independent, bottom-up cost assessment of near and mid-term technologies to improve new aircraft fuel efficiency. Carried out in cooperation with a blue ribbon panel of technical experts and consultants using NASA and DoD-approved models to evaluate aviation technology programs, it assesses over 45 discrete technologies. The analysis identifies significant potential to reduce emissions in-sector through emerging fuel efficiency technologies. The rate of fuel efficiency improvement for new aircraft can be more than doubled through 2034, from about 1% today to 2.2% annually, by the adoption of cost effective technologies to improve engine efficiency, reduce aerodynamic drag, and trim aircraft empty weight.
