A high-lift blended wing body airliner would use half as much fuel as today's airliners for the same payload, says JetZero.
JetZero has put the Z-5 forward for a US Air Force in-air refuelling development program that may make a sizeable contribution to development funding.
Smaller, lighter and much more efficient for a given payload than the Boeing 767 designs it aims to replace.
While its wingspan would be larger than a 767, JetZero says the A-5 will be capable of operating at any airport that can handle an A330.
As a next generation air tanker, it could carry twice as much fuel as the outgoing Boeing design.
Much ligher, with higher lift and lower drag, the blended wing desgin also places its (smaller) engines on top, significantly reducing noise both in the cabin and on the ground below.
A much broader fuselage, with no tail required.
The additional cabin space would be perfect for lightweight, but large-volume hydrogen fuel tanks in a zero-emissions scenario.
Huge, broad cabin appears to have panoramic windows and skylights in this render.
