The ecoDemonstrator Program is a flight test research 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. As of December 2015, over fifty technologies had been tested under the program.[1]

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.[1]

The ecoDemonstrator Program was formally launched in 2011, in partnership with American Airlines and the FAA. As of December 2015, 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.

ecoDemonstrator 737 (2012)

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:[1]

ecoDemonstrator 787 (2014)

Boeing began testing in mid-2014 using a company-owned 787-8 Dreamliner (variable number ZA004, tail number N7874),[2][3] in partnership with the FAA's Continuous Lower Energy, Emissions and Noise (CLEEN) program, NASA's Environmentally Responsible Aviation (ERA) Project, and commercial partners including Japan Airlines, Delta Air Lines, Rolls-Royce, Honeywell, Rockwell Collins, General Electric, and Panasonic. Tested technologies included:[1]

ecoDemonstrator 757 (2015)

The third aircraft in the ecoDemonstrator Program, a 757-222 (tail number N757ET)[4] 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:[1]

  • 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 (tested with NASA under contract for NASA's ERA Project). NASA wind tunnel testing suggest that active flow control could provide a 17% improvement in rudder efficiency, allowing for smaller tails.[5]
  • Insect-resistant wing coatings to improve laminar flow (tested with NASA under contract for NASA's ERA Project). For this testing, the aircraft was operated from Shreveport Regional Airport, which was selected for its high insect population, among other factors.[5]
  • 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.[1][6]

ecoDemonstrator E170 (2016)

The fourth aircraft in the ecoDemonstrator Program, in partnership with Embraer, is an E170.[7][8] Tested technologies will include:

  • LIDAR technology to increase air data reliability by complementing current sensors
  • An ice phobic paint with low adhesive property, preventing accumulation of dirt and insects, and saving water by reducing aircraft washing
  • Special sensors and air visualization techniques to better understand aerodynamics to improve fuel efficiency through new wing designs
  • A Brazilian-sourced biofuel blend made up of 10 percent bio-kerosene and 90 percent fossil kerosene

2018-2021

In early 2018, a compact thrust reverser for very-high-bypass ratio engines with large fans will test nacelle weight and drag reduction aboard a Boeing 777F.[9] It will also test a JAXA Doppler LIDAR detector for clear-air turbulence, an experimental precision approach synthetic instrument landing system (SILS) generating ILS-like guidance from SBAS for older aircraft and the Aircraft Collision Avoidance System for NextGen (ACAS X) replacement for the TCAS using ADS-B.[10]

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.[9]

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 700 nmi (1,300 km) range, increasing to 1,000 nmi (1,900 km) 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.[9]
