Boeing starts extensive X-66 modification of airplane

Published on January 9, 2024

Boeing has started widespread alteration of an airplane that will turn out to be the X-66 Sustainable Flight Demonstrator (SFD), eliminating engines and finalizing 3D metrology scans to update the design and build strategy of the aircraft.

The MD-90 jet’s original wings will shortly be detached to experiment with the Transonic Truss-Braced Wing (TTBW) plan with novel ultrathin wings fitted with supports comprising greater widths and higher-aspect ratios. TTBW’s extensive wing width and sleek efficacy could considerably quicken prospects to decrease fuel usage and releases.

The X-66 is NASA’s first new airplane project concentrated on aiding the U.S. attain its objective of net-zero flying greenhouse gas releases. Ground and flight testing is predictable to start in 2028.

Boeing will make use of 3D modeling software to overlap the prevailing MD-90 arrangement with the new X-66 mechanisms, allowing more precise spatial assimilation and the prospect to categorize and alleviate jeopardies promptly in the alteration procedure.

Boeing will carry on providing updates with the development of the project.
