Boeing’s Latest 777F ecoDemonstrator Flight Programme Tests 100% Biofuel Use and Turbulence Detection

Submitted by on April 7, 2018 – 6:35 pmNo Comment

(GreenAir Online)  Boeing is midway through its latest ecoDemonstrator flight programme that is testing more than 30 technologies aboard a FedEx-owned 777 freighter. Since 2012, the programme has tested more than 55 technologies using four commercial aircraft as flying test beds, with the aim of accelerating new technologies and processes that can reduce emissions and noise, improve airlines’ gate-to-gate efficiency and help meet other environmental goals. The 2018 programme is testing flight deck innovations, propulsion advancements, advanced materials, more efficient flight operations and clear-air turbulence detection. Most test flights are also being powered with 100% paraffinic biofuel, the first time this has taken place using a commercial airliner. Boeing says the testing is to gather performance data and demonstrate drop-in fuel properties.

Through the data gathering and operational experience of using unblended biofuel in flight, Boeing says it will be able to evaluate the fuel system, engine and aircraft performance compared to traditional fossil jet fuel. Additionally, it expects to identify potential opportunities for improved or alternate material components and to support industry approval. Under current rules, 50% is the maximum amount of biofuel that can be blended with fossil jet fuel for commercial flight operations.  READ MORE
