NASA has unveiled its latest X-plane, the X-66A, in collaboration with Boeing, as part of the agency's Sustainable Flight Demonstrator project.
The US Air Force has designated this aircraft, which aims to inform the development of more sustainable single-aisle planes, as the X-66A.
Transonic Truss-Braced Wing Concept
The X-66A features a Transonic Truss-Braced Wing concept, characterized by extra-long, thin wings stabilized by diagonal struts. This innovative design seeks to revolutionize the workhorse of passenger airlines worldwide, the single-aisle aircraft, by making it greener, cleaner, and quieter.
NASA Administrator Bill Nelson expressed the agency's commitment to advancing aviation and addressing climate concerns. He stated, "The X-66A will help shape the future of aviation, a new era where aircraft are greener, cleaner, and quieter, and create new possibilities for the flying public and American industry alike."
The primary objective of the X-66A is to support the United States in achieving net-zero greenhouse gas emissions in aviation, aligning with the goals set forth in the US Aviation Climate Action Plan.
The aircraft represents a significant step toward reducing aviation emissions, with the aim of reaching net-zero emissions by 2050.
Bob Pearce, associate administrator for NASA's Aeronautics Research Mission Directorate, highlighted the importance of transformative aircraft concepts to achieve sustainability targets. He explained, "With this experimental aircraft, we're aiming high to demonstrate the kinds of energy-saving, emissions-reducing technologies the aviation industry needs."

X-plane Designation
The X-66A has been granted the X-plane designation by the Air Force, which recognizes the aircraft as a research platform for validating revolutionary experimental configurations.
While the designation is not intended for full production, it allows for the testing of designs and technologies that can be incorporated into future aircraft models.
Boeing's chief technology officer, Todd Citron, expressed his satisfaction with the X-66A's designation, highlighting its potential to revolutionize flight and play a role in reducing carbon emissions in the aerospace industry.
By integrating the Transonic Truss-Braced Wing configuration with advancements in propulsion systems, materials, and systems architecture, the X-66A aims to achieve a remarkable 30% reduction in fuel consumption and emissions when compared to existing leading aircraft models.
The utilization of single-aisle aircraft in commercial aviation is extensive, leading to a significant contribution to global aviation emissions.
The development of sustainable designs and technologies specifically tailored for this aircraft category holds the potential for a profound impact on emission reduction efforts.
This latest X-plane continues NASA's rich history with experimental aircraft, dating back to the 1940s. As part of the Sustainable Flight Demonstrator, NASA has entered into a Funded Space Act Agreement with Boeing, committing $425 million over seven years.
Boeing and its partners will contribute the remaining funding, estimated at approximately $725 million. NASA will also provide technical expertise and access to its facilities to support the project.
The X-66A represents a significant milestone in the pursuit of a more sustainable aviation industry. By pushing the boundaries of aircraft design and technology, NASA and Boeing aim to pave the way for a greener and more environmentally friendly future in air travel.
