Advanced manufacturer Arris Composites (Berkeley, CA, USA) has revealed a research project with Airbus (Toulouse, France) focused on the production of nacelle brackets
.
The project aims to demonstrate significant reductions in aviation emissions by utilizing innovative manufacturing methods and materials, including composite materials
.
According to Arris, replacing the metal support (220 grams) with a topology-optimized, 3D-aligned continuous fiber composite part (50 grams) resulted in a weight reduction of over 75%; this also translated into highly optimized fuel savings, as hundreds of Such brackets are an important part of making up an aircraft
.
For example, manufacturing 100 aircraft a year, each with 500 cradles, plus 50,000 lighter weight cradles, contributes to saving 113 million metric tons of fuel and 357 million metric tons of CO2 over the life cycle Emissions (impact of weight loss on fuel savings) and conversion factor for fuel to CO2 emissions; see ICCT analysis on commercial aviation)
.
Bastian Schöfer, innovation manager at Airbus, said: "Airbus is moving towards cleaner, more sustainable air travel and needs to explore disruptions with significant impact and practical applications.
Sexual ideas to make this change
.
The way we design and build aircraft is changing as emerging technology companies like Arris share and realize our vision for better air travel
.
We know biomimicry, topology optimization and advanced Composites are the way of the future, and Arris is helping us combine these design and material ideals to create the future of flying today
.
"
In addition, Arris Composites noted that its additive molding technology, which combines additive manufacturing (AM) and high-speed compression molding processes, will have a huge impact on replacement parts and future aircraft structures, proving that it is possible to reduce carbon emissions
.
Airbus itself is committed to exploring such technological avenues to support its vision of more sustainable air travel for future generations
