There was a neat article in Flight Global today outline some detail presented By Boeing on the feasibility of building a hypersonic aircraft.
Got my fingers crossed on this one.

Re: Hypersonic commercial flight?
You do realise that you have started two identical posts!
Considering that you are the OP it might be a good idea if you actually gave a link to the article!

I don't understand you excitement personally. Unless you are rich, it's not going to be for you.

Even if you can’t afford to fly I think it’s a cool idea like Concord was.
Re: Hypersonic commercial flight?
SpaceX already has future transportation on lockdown with the BFR.
Not long now and we'll have 1x daily DXB-IAH, JFK-SYD, SFO-JNB shuttles less than 1 hr in duration carrying a payload roughly 1.5x that of an A380.

Re: Hypersonic commercial flight?
I read that Boeing expects that it will be many years before its hypersonic plane is ready for commercial service, so I wouldn't (at least personally) expect anything of the sort any time soon. I do know, however, that private supersonic jets are hitting the market fairly soon...

Re: Hypersonic commercial flight?
I have a suspicion hypersonic flight has already happened for a while now with experimental aircraft. Boeing appears to have some experience in the field and has done research on two-stage-to-orbit aircraft. Just worth wondering if that stayed as research or did the project actually become reality.
Re: Hypersonic commercial flight?
I remember the National Aerospace Plane back in 1986, ready to fly by 1995.

Depends what you mean by hitting the market. They're in various stages of development, but I wouldn't hold my breath for one being actually delivered to a customer.

What do you mean by "not long" ? First, SpaceX has to make a man-rated vehicle. Then later they have to go to the FAA and sell them the idea of the BFR. How will it be certified ? What will be its safety, how do you evacuate, how do you breathe if there is a depressurization, etc. ? The idea is appealing but I don't see it happening anytime soon or "not long now".

Yes, confidently reported in Air&Space Magazine in ‘86 that we’d all be flying hypersonic airliners decades ago. It’s not happening, folks, not in anybody’s lifetime.

Re: Hypersonic commercial flight?
How would they manage the sonic boom issue? How intense would it be at 90k feet?
I think there is a increased likelihood of seeing such a craft given the competitive dynamics that exist today married w the groundbreaking work being done in material science.

Sonicbooms are why the Concorde had to fly sub-supersonic over the US. I can’t see this being anything but more intensive.
Re: Hypersonic commercial flight?
It is my understanding that current hypersonic flight is limited to rocket technology and scramjets are still in the development phase. Although there have been some success in scramjet testing those successes are limited to boosting a small engine to operational speeds via rocket engines. Has anyone succeeded in testing a craft (even a small version) that has the ability to itself take off, attain hypersonic speeds, and land? Before any human usable aircraft can be built some proof of concept is required.
Re: Hypersonic commercial flight?
Having Greg Hyslop and hypersonic in the same sentence is a little scary.

The article touches on the idea of using an updated turboramjet like was used on the SR71.
It also identifies m5 has being the sweet spot as they think current materials and technology can achieve this velocity.
Re: Hypersonic commercial flight?
Another cool pick up was they have a way to keep the cabin pressurized in an explosive decompression event. Any ideas on what that means?

This was probably what peaked my interest the most. That and the heating of the aircraft.
My guess is some sort of bladder system. Or maybe have an inner and outer skin where both are capable of holding pressure.
I recall that the SR-71 leaked fuel on the tarmac due to gaps that were needed due to the titanium expanding at higher temps. How would they address this? Perhaps a bladder in the wing?

Re: Hypersonic commercial flight?
No, no and no. No hypersonic passenger planes, no blended wing airliners, no rocket planes straight out of The Man in the High Castle. Like it or not, we're stuck with tubes with two ever-more-efficient fanjets for as far as anyone can see. Development costs are just going to be too high to spread across a mass-market rollout. Sorry.

I sorta have to agree. However there could be a paradigm change with the electrification of flight. Aviation Week launched a huge article going into the state of the industry:

The ability to transfer energy between the different spools is very interesting.

You are correct with current technology.
25 or 50 years from now it might actually be possible; but, would still be very expensive and I doubt within the price range of passenger aircraft.
Have a great day,
