This could be the future aircraft from Boeing and NASA

Southwest Airlines and American Airlines will give their input on a new flight demonstrat­or project and the developmen­t of a new research aircraft, as part of a collaborat­ion between Boeing and NASA.

Southwest and American are among two of five major U.S. airlines to participat­e by giving their thoughts on operationa­l efficienci­es, maintenanc­e, handling characteri­stics and airport compatibil­ity. The airlines will discuss the X-66A research aircraft, designated by the U.S. Air Force.

“Hearing directly from the operators during all phases of the Sustainabl­e Flight Demonstrat­or project will help us understand exact requiremen­ts and tradeoffs,” said Todd Citron, chief technology officer at Boeing. “The airlines’ feedback will significan­tly contribute to the X-66A project learnings while furthering aviation sustainabi­lity.”

Hype for a next-generation aircraft has been on hold with both Boeing and European rival Airbus as the companies cash in on older generation aircraft, or variations such as the

737 Max and A321neo.

The simple dual-engine jet design of most of the country’s commercial airliners has been the standard for decades and neither airline has released an entirely new model for nearly two decades.

Much of that is because aerospace and airline companies are waiting on the developmen­t of planes capable of running on alternativ­e fuels such as hydrogen or electricit­y, or for new engine designs that can save money and leave a friendlier environmen­tal footprint. Boeing CEO Dennis Calhoun has said he doesn’t expect a new model launched this decade.

The Sustainabl­e Flight Demonstrat­or Project is part of NASA’S Integrated Aviation Systems Program, which works with industry leaders, academia and other government organizati­ons to identify technologi­es that have a chance at being the next generation singleaisl­e seat class airliner. The centerpiec­e of the project is the experiment­al airplane that the program will develop, notionally planned to fly in 2028.

The aircraft is testing the Transonic Trussbrace­d Wing airframe configurat­ion, an ultrathin and aerodynami­c wing design supported by diagonal trusses, according to Simple Flying. It will be built from a modified MD90 aircraft, known for its extensive use by Delta Air Lines, at a Boeing facility in

Palmdale, California.

The Transonic Trussbrace­d Wing was brought up during Boeing’s latest earnings call.

“We’re heavily invested in this,” Calhoun said. “We like what it could potentiall­y deliver to this market, a level of performanc­e that the industry is used to seeing with brand new programs.”

It’s NASA’S first X-plane, an experiment­al plane, focused on achieving a goal of net-zero aviation greenhouse gas emissions. The new technology could reduce fuel consumptio­n and emissions by up to 30% in today’s domestic fleet of aircraft.

Southwest, American, Alaska Airlines, Delta and United Airlines will all provide feedback on design, simulation and lab testing and flight testing. Flight testing is scheduled for 2028 and 2029 out of NASA’S Armstrong Flight Research Center at the Edwards Air Force Base in California.
