Boom Supersonic quietly drops the Overture's cruising speed from mach 2.2 to mach 1.7

Tue Aug 24, 2021 1:41 pm

Signs of trouble? .5 mach is a pretty significant loss in performance, with no explanation to boot..

Just wait until it doesn't fly at all! Will there be an announcement then?

Well, I think all of us saw something like this coming.

No need to drop the speed when it’s not gonna fly

Wasn’t this already noted awhile back? At least it was to me. I believe it came up around the UA “order”

Not sure when exactly the change was made but the UA PR does quote it’s top speed as Mach 1.7 and not 2.2, so at the very least it dates till then:

Not sure I believe it is significant, in my line of thinking the key's are to have supersonic flight with minimal sonic boom, not to have the fastest supersonic a/c or to compete with the Concorde. If reducing the speed makes some of the engineering problems easier, I still say go for it, especially when it may still knock an hour or so from the current non-supersonic flight times.

Agreed, I would think this forum would applaud any advances in aviation and this is certainly a step forward at any supersonic speed.

It definitely would be, I just hope this change doesn't mean their team suddenly found out about the limiting factors of temperature.

Always got that vibe that it was a “fly-by-night” scam, honestly I am shocked that a huge global carrier like UA fell for it.

It’s not that people want to see them fail (in most cases) it’s just that anyone with experience or a history of following aviation sees right through them and other companies like them.

They announce a project that is going to revolutionize the industry. Cheaper, faster, higher, more fuel efficient. It’s going to blow your minds.

Then they release the fine print-all they need is financial backing, offices/production sites, staff, a viable engine, a few pieces of technology that haven’t yet been invented, as many customers as possible, oh and also need to sidestep a few FAA or other govt regulations. BUT they’re the next big thing, first flight expected in 2 years.

Boom has changed the names, logos, specs, announced customers, had big press releases etc. in terms of actual flying? None.

(And I don’t think customers can be touted too highly at this stage- if you don’t believe me, go take a look at Concorde and the 2707’s order books)

Must be easier to engineer for Mach 1.7 than 2.2. Should be more efficient too. As someone stated, it should lessen the boom too.

What engine will be finally used for their big one?

I have a feeling we are heading into a high tech engineering startup bubble situation similar to the dotcom bubble back in the late 90s. Fueled by the egos of the likes of Musk and wannabe Musks, though Musk himself will most likely get out relatively unscathed with SpaceX actually showing some (physical) results.

How long before - With no official announcement, United Airlines quietly drops the Boom Supersonic order.

Going transsonic then supersonic is going to guzzle gas regardless. So now you have a slower gas guzzler, making its case even more difficult.

But yeah it was already known, same as Aerion went from 1.6 to 1.4 to nowhere.

I think we're all applauding advances like this one. But, as of right now, Boom feels more like Nikolas Motor Company than Tesla, let alone Ford/GM/Toyota/VAG/Stellantis: a too good to be true venture that feels like it'll end up bleeding money and belly up...

We're already there with electric cars (and trucks). Nikola already blew up, out of all these startups working on high end electric cars, at least half of them will never deliver.

Yes. It was disappointing then, it's disappointing now.

Even easier to engineer for Mach 0.8 and far more efficient too.

That period created brands that are household names ( Amazon, Google, Android, too many to name ) as well as lots of tech that was bought out by big names and is still in day to day use.

Boom isn't one of those, IMO.

SpaceX already has the kind of results and mindshare Boom only dreams of. Tesla is already a household name, Starlink is on the verge of being one.

I'm not sure ego is a bad thing. Steve Jobs was a maniacal jerk, but IMO the world was a better place with him than without him, although some of his long suffering colleagues might not agree.
