Ultra High Bypass Technology has the potential for significant reductions in fuel burn, noise and emissions. Geared Turbofan Technology can enable these benefits by optimizing fan and core operation and allowing a reasonable engine and core size. The first generation Geared Turbofan was successfully demonstrated under NASA/PW partnership. Significant contribution toward ERA N+1 Goals was achieved. A second generation technology to further improve performance to meet ERA N+2 Goals is being planned collaboratively by NASA/PW. GTF NG technology ground test engine demonstrations are planned as part FAA/NASA/PW CLEEN partnership in 2014 and possibly 2015. Future long range plans (to 2020) are looking for opportunities to collaboratively conduct engine and flight demonstrations to validate both ERA UHB and P&W GTF NG technologies
