In an era where sustainability has become more than just a catchphrase, it's crucial to consider its impact and application in the aerospace industry. The intricate dance of innovation and responsibility paints an interesting landscape for the future of aerospace sustainability.
This article will delve into the emerging trends and progressive steps being taken within the industry to harmonize advanced technology, environmental impact, and the longevity of resources, according to Bryan Christiansen, a writer for Aerospace Manufacturing and Design, who wrote about five emerging trends that the Aerospace industry needs to pursue if a world of NetZero by 2050 is to be achieved.
Aerospace And Carbon Dioxide Problem Emissions
The aerospace industry emits nearly one billion metric tons of carbon dioxide annually, and this number is projected to triple by 2050 if appropriate sustainability measures are not implemented, writes Bryan Christiansen in an article appearing on Aerospace Manufacturing and Design website in May. Given these circumstances, Christiansen points out that the industry faces constant pressure to thoroughly evaluate its operations and adopt innovative technologies in order to effectively mitigate greenhouse gas emissions.
So what can be done?
Here are five sustainability trends that the aerospace industry should keep an eye on, according to Christiansen. These trends are crucial for the industry's future as they address environmental concerns and pave the way for more sustainable practices. By staying informed and proactive in these areas, the aerospace industry can contribute to a greener and more responsible future.
Next-generation aircraft design
Aircraft manufacturers primarily focus on optimizing aircraft designs to achieve optimal fuel efficiency and weight reduction. This not only leads to a more environmentally-friendly impact, with reduced fuel consumption and lower emissions but also ensures a higher level of efficiency and performance in the aircraft.
The manufacturers can improve performance by making slight improvements to aircraft by:
- Enhancing engine designs for improved fuel efficiency
- Improving aerodynamic designs
- Exploring the use of lightweight fabrication material
- Using advanced coatings
The utilization of sustainable aviation fuels
The utilization of sustainable air fuels (SAFs) is taking shape as airlines strive to achieve net-zero emissions. These fuels have similar chemical characteristics as fossil fuels but with fewer ozone depletion capabilities — they release carbon that has already been extracted from the environment. Emissions from SAFs have a shorter life cycle reducing their Ozone depletion rates further.
Utilizing air transportation systems within urban areas.
Another trend shaping sustainability in the aerospace sector is the expansion of urban air mobility. Two technologies are frontrunners in this sector:
- Electric vertical takeoff and landing (eVTOL)
- Drone Deliveries
Cutting-edge propulsion technology
Modern and future aircraft will not rely only on fossil-powered engines. The push for sustainable flights is revolutionizing the design of aircraft and spacecraft propulsion systems, Christiansen writes. Advanced propulsion technologies focus on increased efficiency, better fuel range, and higher aircraft performance.
Some advanced propulsion systems include:
- Electric
- Hybrid
- Solar
- Fuel Cell
Enhance air travel management for optimal efficiency and effectiveness
Some airlines still use old air travel management systems, Christiansen writes, which increases inefficiency in route planning and asset management. Airlines can minimize their carbon footprints by digitizing air travel management and leveraging advanced technology to improve route planning and asset maintenance and enhance operational efficiency.
Summary
The transition towards net-zero emission in the aerospace industry demands radical changes in all facets of operations, writes Christiansen. He points out that reducing greenhouse gas emissions is not a reserve of airlines only. The entire industry, including manufacturers and other entities in the supply chain, should adopt sustainable technologies to reduce waste and pollution.
Christiansen concludes that the sector should leverage advanced technology to maximize asset and operational efficiency. The ultimate goal of sustainability-driven innovation in the aerospace industry is to ensure net-zero emissions for a safer and cleaner planet.
