A bid to re-establish supersonic flights some 12 years after Concorde was retired received a boost this week.
According to a Reuters report, Airbus was granted a patent by the US Patent Office, as the aircraft manufacturer works on plans to create an aircraft that can fly from Paris to Tokyo in three hours.
Airbus revealed last year that it was collaborating with international research firms to evaluate Mach 6 flight technology.
The manufacturer said its Zero Emission High Speed Transport concept should be seen as the “first step” in its supersonic journey.
It said it was working on two projects: Japanese-European collaboration Hikari; and European-Australian partnership Hexafly International.
The firm said today: “Airbus Group and its divisions apply for hundreds of patents every year to protect intellectual property.
“These patents are often based on research and development concepts and ideas in a very nascent stage of conceptualisation, and not every patent progresses to becoming a fully realised technology or product.”
