It's been more than ten years since Concorde made its final transatlantic flight. But there's a new generation of supersonic passenger aircraft beginning to emerge, boasting speeds at least twice as fast as current commercial planes. While these planes will first appear in the private and business jet market, catering only to the super rich with gargantuan price tags and first class service, supersonic may eventually reach regular holidaymakers.

I imagine if you take the flight profile high enough, the book isn’t an issue. Don’t know if that’s the plan here since they are only talking about 2x normal jets, and that it not quite enough for suborbital.
I meant boom, not book.
Race to be the new Concorde! became Racial issues and strife to be the new Concorde!
The “boom” is a huge issue ... as is cost ,, these jets will guzzle fuel.. The Concorde was SLOWER than a 747 for NY==>London on most days because of maintenance related ground delays... At most you can cut a few hours off a long route ... I can cut those hours off without a new plane just by streamlining the on the ground aspects of the flight
They probably have the glide capabilities of a lead brick.
Arrive at airport, wheels up 15 minutes later and 4 hours, New York to London. Versus, arrive at airport, board plane 2 hours later, depart gate, wait on tarmac for 45 minutes, take off from JFK and arrive at LHR 8 hours later.
Commercial jets, JFK-LHR, arrive at airport to depart airport, 11-12 hours. Private supersonic, arrive at airport to depart airport, 4-1/2 to 5 hours.
Didn’t you read the thing? These are for the super rich. Sonic booms? That’s for the little people. They’ll ride above all that.
The NY-London leg was too short for supersonic flight to make a difference in total trip time (defined as the time between arriving at airport to time departing the destination airport). As you note, check-in, security, boarding, gate delays, getting your bags at the other end and going through customs, etc account for much of the total time.
Now, for LA to Japan/China/Australia supersonic flight WOULD make a big difference, but the early planes just didn't have the range.
You know the only reason they are doing this is to recover the time people have lost in airport security checks.
Fuel efficiency verses distance traveled is the limiting factor here. Until supersonic aircraft can match their slower rivals, they will continue to be the tools of the military and the very wealthy. Simple economics folks. I'm not saying it can't be done but it sure ain't happened yet.
That certainly makes sense. While time is money, it is only worth so much money.
But it sure was great for London to DC. My trip was 3hrs, 45 min. I arrived before I left. Would have been 15 minutes less but the Queen was at Windsor Castle instead of Buckingham Palace. They always delay going supersonic under those conditions.
I’m showing London to DC as an around an 8 hour flight.
About the last picture at the original link. Is that a wind up car the bottom of the picture?
Yeah, I assumed that that was a typo. I knew what you meant. Being former Navy, I have stood on the deck of a ship and had American fighters fly over a supersonic speeds at low altitude. By that, I mean really low altitudes. The experience is awesome. You can't turn your head fast enough to follow them passing over. The sound wave is like a physical blow.
On the other hand, I had a great aunt that visited us in Toledo, Ohio from southern Indiana. While talking to me waiting for her fight home she told me of her first trip between the two that took her almost two weeks on stage coaches and stay overs. Now she would be home in two hours. She died at the age of 93. Think of this when you are frustrated at the delays at airports.
Seattle to Yokohama via MSTS was 14 days.
I took this trip back and forth six times, 1951-1961.
The market is Private and Biz-jet, as the article says.
Range and economy are the real limiting factors. If they can overcome that, the world market could be as high as 500 aircraft.
Hi.
What happens when flight propulsion is accomplished by the change in mass vs chemical reaction?
Just asking...
5.56mm
My son did some of the design work for an earlier version of the Aerion with only 2 engines. It was never built, but he did a rendering of it for the cover of Aviation Week - about 6 years ago as I recall. The economics weren’t there at a time when private aviation was being hit with death blow after death blow.
The market has always been business aviation, not scheduled commercial airlines.
I wonder what the actual takeoff/touchdown time of that SR-71's sub two hour NY to London time was, considering they started the radar clock when it departed NY at 80,000 ft.
