Boeing tests 30 sustainable technologies on its 777-200ER ecoDemonstrator

SEAT – Boeing has unveiled its 2022 ecoDemonstrator with a livery that pays tribute to a decade of testing to reduce fuel consumption, emissions and noise. The latest ecoDemonstrator, a Boeing-owned 777-200ER, will test approximately 30 new technologies aimed at improving sustainability and safety for the aerospace industry, including a water-saving system and technologies to improve operational efficiency.

“Boeing is committed to supporting our customers and commercial aviation industry to meet our shared commitment to achieve net-zero carbon emissions by 2050,” said Stan Deal, president and CEO of Boeing Commercial Airplanes.

During six months of flight and ground testing beginning this summer, the 2022 ecoDemonstrator will evaluate:

Manufactured additive aircraft and engine components, including an auxiliary engine exhaust duct (APU) support panel and an engine mount. The aim is to reduce the weight in the aircraft, which saves fuel, and to reduce waste in the production process. Both were developed by the Boeing Additive Manufacturing Innovation Center.

• Boeing and NASA continue work on SMART vortex generators, small vertical vanes on the wing that improve aerodynamic efficiency during takeoff and landing. Shape memory alloys co-developed with NASA allow the vortex generators to retract into the wing during cruise, improving fuel economy and reducing carbon emissions.

• In partnership with Universal Avionics, the ecoDemonstrator pilots will help test the next generation of head-worn head-up display (HUD) and Enhanced vision system (EVS) cameras. The SkyLens HUD is a transparent screen that places important information directly in a pilot’s field of view. This technology, combined with EVS, provides an enhanced vision system that allows pilots to see in low visibility conditions, improving safety by improving situational awareness and reducing aircraft weight.

• In collaboration with Diehl Aviation, the ecoDemonstrator will test a water-saving system that uses wastewater from hand washing to flush toilets. By saving water – possibly over 400 lbs. (181 kg.) Weight per flight — the system helps reduce fuel consumption and CO2 emissions.

• In collaboration with Meggitt, Boeing is testing the evacuation performance of a new in-flight fire extinguishing agent for the aircraft’s cargo compartment. This effort is part of Boeing’s commitment to eliminate the use of Halon 1301 on all commercial aircraft models. International environmental and aviation regulations have imposed deadlines for the use of Halon 1301 – the standard aircraft fire extinguisher – due to its ozone-depleting properties.

• Boeing is testing several technologies aimed at improving operational efficiency, including a capability that could improve pilots’ situational awareness while taxiing aircraft. This includes combining airport data sources with Jeppesen airport maps to enable single engine taxi transportation: reduce fuel consumption.

• In collaboration with Collins Aerospace, Boeing is testing the performance of a new air cooler that uses an environmentally friendly refrigerant. Aircraft galleys contain refrigerators to keep food and drinks cold during the flight. As in consumer refrigerators, refrigerants often contain industrial chemicals that are potent greenhouse gases if they leak

“The Boeing ecoDemonstrator program brings together the two key ingredients for a more sustainable future: innovative technologies and partnerships with customers, suppliers, government agencies and academia,” said Chris Raymond, Boeing Chief Sustainability Officer. “We celebrate past successes and look forward to continuing this iconic program to decarbonise aviation together.”
