Boeing unveils new 777 ‘ecoDemonstrator’ test jet

3 min read

(CNN) – American aircraft maker Boeing has unveiled its new 2022 ecoDemonstrator aircraft – a modified, 20-year-old 777-200ER that will be tasked with testing new technologies aimed at making air travel more durable and safer.

The ecoDemonstrator will reportedly begin a six-month series of tests on both Earth and Sky, starting this summer.

The campaign includes projects designed to reduce fuel consumption, emissions and noise by incorporating sustainable materials from 30 or more technologies developed for testing during the campaign.

For example, Boeing is collaborating with NASA to develop SMART vortex generators – small vertical vans on the wing designed to improve aerodynamic performance during takeoff and landing.

Other projects include a system designed to preserve the aircraft’s gray water – sink-washed water will be used to flush toilets, reducing the weight of the aircraft. happens.

The aircraft will also be used for testing on “environmentally preferred” refrigerants, a new fire-suppression agent to reduce greenhouse gas emissions and a better vision for pilots to improve operational efficiency. System

Meanwhile, Boeing will continue its comprehensive study on the effects of sustainable aviation on reducing fuel emissions.

The aircraft maker says the team plans to power the 777-200ER using a 30/70 mix during its trial period. Sustainable Aviation Fuel (SAF) And conventional jet fuel.

Boeing’s ecoDemonstrator program began a decade ago and takes technologies out of the lab to test them in an operational environment.

It has tested a total of about 230 technologies to “help decarbonize aviation, improve operational efficiency, and enhance safety and passenger experience.”

The Boeing 2022 ecoDemonstrator will test 30 technologies to enhance safety and sustainability.

The 2022 ecoDemonstrator aircraft, with registration number N861BC, was first flown to Singapore Airlines in 2002, then flew with Air New Zealand and Suriname Airways in its 20s.

It has been repainted with an earth-themed lever, which Boeing says marks a decade of testing to reduce fuel consumption, emissions and noise.

Stan Dale, President and CEO of Boeing Commercial Aircraft, said in a statement: Is determined. ”

“The rigorous testing of new technologies in the ecoDemonstrator program further improves the environmental performance of our products and services and is invaluable in continuously improving safety.”

Boeing said in a statement that about a third of these tested technologies have already been added to its products and services.

The aviation industry is pushing for a more sustainable flight environment, despite long-standing criticism.

Various reports from industry watchdogs and environmental groups estimate that aviation emits 2-3% of global CO2 emissions.

At its annual meeting in October 2021, IATA, the International Air Transport Association, announced a resolution in support of pure zero carbon emissions by 2050.

At this year’s IATA AGM, taking place June 19-21 in Doha, Qatar, the “Focus on Sustainability” session will address industry-related issues, including single-use plastics, SAFs and the challenges of achieving sustainability. – Including net zero carbon emissions by 2050. .

Many airlines are already committed to offering carbon neutral flights and finding alternative fuels to reduce pollution.

Earlier this month, Spanish airline Air Nostrum announced that it was Ordering 10 new hybrid aircraft. Airlander 10 aircraft are to be delivered by 2026.
