The ecoDemonstrator Program is a flight testresearch program of aircraft company Boeing, which has used a series of specially modified aircraft to develop and test aviation technologies designed to improve fuel economy and reduce the noise and ecological footprint of airliners. From 2012 through 2018, the five airplanes involved have tested 112 technologies: half remain in further development and a third are being implemented like iPad apps for pilot real-time information to reduce fuel use and emissions; custom approach paths to reduce community noise; and 777X cameras for ground navigation.
History
The ecoDemonstrator Program followed Boeing's Quiet Technology Demonstrator program, which operated between 2001 and 2005 to develop a quieter engine using chevrons on the rear of the nacelle and exhaust nozzles. These chevrons were later adopted on the 747-8 and 787 Dreamliner aircraft. The ecoDemonstrator Program was formally launched in 2011, in partnership with American Airlines and the FAA., the ecoDemonstrator program has used three aircraft as testbeds. The first, a 737-800 owned by American Airlines, was used in 2012 to test over 15 technologies. The second aircraft, a company-owned 787-8 Dreamliner, was used to test over 25 technologies. In 2015, a 757 was used to test over 15 technologies, in cooperation with NASA and the TUI Group.
Using a Next Generation 737-800, Boeing demonstrated laminar flow technology for winglets, improving fuel efficiency by 1.8 percent. The aircraft tested other technologies, including:
NASA's Airborne Spacing for Terminal Arrival Routes system, intended to allow increased landing frequencies
Other software and network technologies to optimize flight planning and fuel loading
2015: Boeing 757
The third aircraft in the ecoDemonstrator Program, a 757-222 owned by Stifel's aircraft finance division, began flights in March 2015. The aircraft was painted in the livery of the TUI Group, which collaborated on the program. Tested technologies included:
Technologies to improve laminar flow, including a "Krueger shield" to protect the leading edges of the wings from insects
Active flow control on the vertical tail. NASA wind tunnel testing suggest that active flow control could provide a 17% improvement in rudder efficiency, allowing for smaller tails.
Insect-resistant wing coatings to improve laminar flow. For this testing, the aircraft was operated from Shreveport Regional Airport, which was selected for its high insect population, among other factors.
Solar and thermal energy collecting systems, used to power dimmable cabin windows
Following the test campaign, the aircraft was demolished, and Boeing reported that 90% of its material was reused or recycled.
the compact thrust reverser with a conic monolithic structure reduced duct pressure losses, to save up to 1.5% of fuel towards shorter nacelles;
thermoplastic blocker doors in the thrust reverser lowered noise;
100% paraffinic biofuel could improve specific fuel consumption by 3-4% with lower engine maintenance and smoke levels, for a reduction in greenhouse gases up to 80%;
to optimize routing efficiency and safety: sharing digital information between air traffic control, the flight deck and an airline's operations center;
Connected galleys, lavatories, and cabin temperature and humidity sensors;
Cameras for an outside view for passengers.
2019-2021
In 2019, fly-by-wire control for auto-takeoff and auto-taxiing will be tested on a B787, along with a "smart cabin" with advanced environmental control and power features. By 2021, autonomous operations and hybrid electric aircraft propulsion will be tested on a small regional airplane, to be developed with Boeing HorizonX ventures arm and JetBlue Airways-backed startup Zunum Aero, based in Kirkland, Washington. The initial 19-passenger design is optimized for a range, increasing to by 2030 as electric technology advances. For shorter ranges, batteries alone will suffice, to be swapped or fast charged at airports for fast turnarounds. Targeting 40-80% lower operating costs than current regional airliners and an early 2020s introduction, it would be the first of a 10-50-seat aircraft family.
