Airbus Patents Mach-4 Bizjet Concept

Airbus has been granted a U.S. patent for an airplane that could fly commercial passengers at speeds up to Mach 4.5, according to various news reports this week. The plans show the hydrogen-fueled airplane would take off vertically, propelled by turbo jets, then a rocket motor and wing-mounted ramjets would propel the aircraft as high as 100,000 feet. The aircraft then would transition to level flight. That flight profile would minimize the sonic boom impact on the surface, according to Airbus. FULL STORY
