Zusammenfassung:Hofacker looks at the history and promise of Boeing's Transonic Truss-Braced Wing demonstrator. Concepts for TTBW airliners date back to the 1950s, when Swiss aerodynamicist Werner Pfenninger proposed an ultralong, thin wing braced by rigid support beams to maximize aerodynamic lift. In the following decades, researchers from NASA, the aviation industry and universities have studied the concept. Boeing's version originated in 2006, when technical fellow Marty Bradley was searching for a topic that the company's Advanced Concepts group could begin researching that would represent a significant advancement for the aviation industry. After a critical design review, currently scheduled for early 2026, construction of the demonstrator will begin. Boeing plans to modify a retired MD-90 aircraft, one of two that are in storage at Southern California Logistics Airport, also known as Victorville.
