Boeing [NYSE: BA] and NASA have partnered with major U.S. airlines to spearhead the Sustainable Flight Demonstrator (SFD) project and develop the new X-66A research aircraft.
This collaborative effort aims to harness the power of industry expertise and advance the Transonic Truss-Braced Wing (TTBW) airframe configuration, with the ultimate goal of achieving net-zero aviation greenhouse gas emissions.
Alaska Airlines, American Airlines, Delta Air Lines, Southwest Airlines, and United Airlines, collectively forming a new sustainability coalition, will play a crucial role by offering invaluable insights into operational efficiencies, maintenance practices, handling characteristics, and airport compatibility.
The X-66A Takes Flight at EAA AirVenture Oshkosh
The excitement surrounding the X-66A project reached new heights when NASA and Boeing unveiled the aircraft’s stunning livery at EAA AirVenture Oshkosh.
According to Todd Citron, Boeing’s chief technology officer, direct input from airline operators throughout the Sustainable Flight Demonstrator project will prove instrumental in comprehending precise requirements and making necessary tradeoffs.
The invaluable feedback from the participating airlines promises to contribute significantly to the overall learnings of the X-66A project while simultaneously advancing the cause of aviation sustainability.
Paving the Way for Green Aviation
At the heart of this ambitious endeavor lies the Transonic Truss-Braced Wing (TTBW) airframe configuration, which will be showcased in the X-66A, built from a modified MD-90 aircraft at a Boeing facility in Palmdale, CA.
NASA’s selection of the TTBW configuration marks a significant milestone as it represents the agency’s first X-plane dedicated to the pursuit of net-zero aviation greenhouse gas emissions.
A Greener Future: The TTBW Design
The adoption of the TTBW design in future aircraft, in conjunction with anticipated advancements in propulsion systems, materials, and systems architecture, holds the potential to reduce fuel consumption and emissions by an impressive 30% when compared to today’s domestic fleet of airplanes.
Such an achievement would mark a giant leap forward in the global fight against climate change and position the aviation industry as a pioneer in eco-friendly practices.
U.S. Airlines Step into the Limelight
The U.S. airlines participating in this leading endeavor will actively contribute their expertise throughout various stages of the project:
Design Insights for Sustainable Operations and Airport Compatibility
Airline participants will provide invaluable feedback on sustainable operations and airport compatibility. Although the X-66A boasts an impressive wingspan of 145 feet, the versatile TTBW design can be adapted to airplanes of different sizes and missions.
To ensure seamless integration, the possibility of incorporating folding wingtips to accommodate existing airport infrastructure will be explored.
Realistic Flight Simulation and Testing
Airline pilots will get the chance to experience the X-66A through a state-of-the-art flight simulator, enabling them to assess the aircraft’s handling characteristics in a safe and controlled environment. This invaluable data will contribute to refining the aircraft’s design and performance.
Evaluating Performance through Flight Testing
As modifications are made to the X-66A, airline operations and maintenance teams will be actively involved in evaluating the aircraft’s performance during flight testing. This collaboration ensures that real-world insights from experienced professionals are incorporated into the ongoing development process.
