Boeing is working on plans for a hypersonic passenger aircraft that would cut the journey time between London and New York to around two hours. It is expect to travel at Mach 5, crossing Atlantic in 2-3 hrs.
Supersonic transport becomes hypersonic at 3,800 mph at Mach 5 and above. American based Hermeus is developing this render of a hypersonic passenger aircraft that would make a NYC to London trip in 90 minutes, 3 times faster than Concorde was ever able to.
Hypersonic flight is approximately 5 times the local speed of sound, or Mach 5! The Vehicle Analysis Branch at @NASA_Langley has been instrumental in advancing hypersonic flight through the development of hypersonic aircraft and more!
What people are saying?
JamesDyy Ok, this sounds good. But first they need to make this a reality. Then it will become a new aircraft (exclusive for the rich). “We focused on the business class and first class travelers”.
Colin So, I’ve done a bit of research on this.. the optimal air speed is just over 500mph. Anything faster like this..just isn’t a sustainable business model. This is y most new planes still travel at 500mph.
