demonstrator

NASA and Lockheed Martin’s quiet, supersonic research aircraft makes its inaugural flight.

Manufacturer proposes to instead focus its efforts on developing thin-wing technology, which it believes may have broader applications.

Boom Supersonic’s XB-1 demonstrator creates a sonic boom not audible from the ground below, potentially opening up opportunities for supersonic flight over land.

New Zealand flag carrier adds a Beta Alia conventional takeoff and landing (CTOL) demonstrator to its existing order.

Space agency contractor Electra is developing hybrid-electric aircraft that require just 150 feet of runway for takeoff and landing.

Heart Aerospace’s Heart X1 demonstrator is the precursor to its 30-seat, hybrid-electric regional airliner, the ES-30.

Manufacturer Electra performs demonstration flights for the military under a $85 million contract with the U.S. Air Force.

The manufacturer’s hybrid-electric short takeoff and landing (eSTOL) design goes airborne at neighborhood driving speeds through the use of blown lift propulsion.

The company has previously discussed its plans for intracity air taxi routes using its flagship, battery-electric model.

XB-1 flight testing and evaluations will inform development of Boom’s Overture, a supersonic jet designed to carry 64-80 passengers twice as fast as subsonic airliners.
