Aerospace Startup Will Build A Supersonic Mach 2.2 Aircraft (fortune.com) 150

A new commercial aircraft will fly more than twice the speed of sound, traveling from New York to London in 3.4 hours. An anonymous reader quotes Fortune: Colorado-based startup Boom Supersonic is one step closer to making such travel a reality after securing $33 million in investments to construct and fly its first supersonic jet, the XB-1 demonstration and testing craft, according to TechCrunch... With the new funding, Boom will be able to put that concept -- and the technology needed to power it -- to the test. "This funds our first airplane, all the way through flight tests," Boom founder and CEO Blake Scholl told TechCrunch. "Now we have all the pieces we need â" technology, suppliers and capital â" to go out and make some history and set some speed records."
They'll be testing a prototype that's one-third smaller than the commercial version within the next year.

      There are many more like that. For example, Malwarebytes [malwarebytes.com] is software named after the problem it is supposed to cure. Doesn't anyone at BOOM have a mother?

      Son: Mom, what do you think of the name BOOM for our company?

      Mom: No, son, that's not a good name.

          Is it really that expensive? I know some people who had run a small startup automaker that raised 30-something million. They were about 3 months out from first commercial deliveries (having made a couple dozen prototypes to various degrees, ranging from empty shells to full builds), with about $10m still left in the bank - when the board decided to bring on a guy from Detroit (Paul Wilbur, the guy responsible for the Chevy SSR [netdna-cdn.com], and a bunch of other train-wrecks-in-car-form), who then proceeded to run the company into the ground.

          Are aircraft that much more expensive than cars, that you can't even build a demonstrator for that kind of money? To be fair, the automaker's vehicle was technically classified as a motorcycle, so their regulations weren't as onerous as for most cars (but they still did full crash and crush tests anyway, voluntarily). But, I mean, they just churned out prototypes one after the next.

    The 3 or 4 hours of travel time I'm saving doesn't really justify the proposed ticket pricing...

    "The company hopes the Boom jet will take three hours and 15 minutes to fly from New York to London for a price of $2,500 per passenger in either direction, based on its initial prototype. Transatlantic flights currently take more than twice that time."

    I fly from Boston to Munich, Frankfurt, Paris or London about twice every 3 months. Ticket prices for a round trip, in the winter, range from 600 - 800$, and in the summer the prices range from 800 - 1200$ (I fly lufthansa over the ocean, then wizz air to final destination, cheap af and lufthansa offers very good service for the price).

    If you are going to charge 2500$ for a one way ticket, and the only benefit is I save 3 or 4 hours in travel time, I won't even think twice about it, fuck that.

    3 hours of my time is not worth proposed ticket price (~3x for one way, ~6x for round trip).

          Concorde did not recoup its development costs due to the small number of operational aircrafts (only 20 were ever produced, 14 of which saw commercial use). However they were operationally profitable, meaning their usage generated profit over and above all the operational costs.

          • And it might have done, but the economics of Concorde were predicated on cheap oil, and it became operational at the same time as the energy crisis of the early 1970's, when the price of oil sky-rocketed.

            Because of this, and because Governments typically make policy on a short-term, knee-jerk basis, the revised version of Concorde (which would have been cheaper to operate) was cancelled.

          This always gets said, and again, it's false. BA did make money [wikipedia.org], which is why they flew it for as long as they did. It just didn't enough money to pay for spare parts as the planes aged (they cannibalized grounded Concordes until that became unsustainable) and, ultimately, replacement aircraft. Limited to only a few routes, Airbus wouldn't tool up to support a dozen or so planes when there's much more money to be made in fleets of subsonic aircraft. In short, the Concorde died of old age and lack of supporting infrastructure. But make no mistake, for 60's and 70's technology, the Concorde was really really great. Well loved by both passengers and pilots.

      I have an uncle who flew the Concorde from NYC to London frequently. It was entirely worth the extra money to his company to have him there and back in one day. When he would make trips like this, it was to talk to investment banks and the like, and the stock price would take a non-trivial tick upward as a result. The six-hour-plus savings in his time was entirely worth the cost. Moreover, not having to sleep on a plane and have a shitty night's sleep rendering him less effective the next day was even better.

      Now, there aren't many people who are like that, but the number is also not zero. Given the large collection of companies in the northeast with insane valuations (e.g., Big Pharma), I'd wager that there is still a market for supersonic travel to London at what amounts to business-class prices.

      It's because fluid flow is not only computationally difficult but also the rules are all empirical with uncertain boundaries between different domains so sometimes it's not clear what equations to use. That's why there is still wind tunnel testing of scale models. Since the end product is going to be very large (and supersonic wind tunnels are very difficult things to deal with apart from very short test durations) it makes sense for the scale model to be a

  • Honestly it should say "may" not "will", these things seem to rarely work out as proposed.

      Actually it should say "fantasizes", not "will build". It's lunacy. Where the hell is my atomic flying car?

  • Is that like an ATM Machine?

    50 year plus old turbojet engines, small and less sophisticated wing (missing vortex lift), only a fraction of the resources of Concorde design/development - won't cut it.

    carbon/composites instead of RR58 aluminium alloy, CFD modeling and current FWB controls will surprisingly or not fail to produce meaningfully better performance

    kudos to the Concorde designers who still have to be topped almost 50 years after its first flight

      Someone needs to make a movie about those guys. Politicians, engineers, businessmen, assemblers, aircrews etc. etc. etc. from two countries of different cultures, different languages, drive on opposite side of the road and were at war with each other for centuries until 20th century.

  • I really do, but the endless parade of of proposed supersonic transports starting with the Boeing SST, that were eventually canceled makes me pretty pessimistic.

    The basic technology for supersonic flight hasn't changed. Its not clear why the they claim that the will succeed where so many other companies have failed.

    There is a long history of similar projects and they all face the same challenges: airframe, engines, engines, engines, engines, cash flow, actual demand from buyers, and safety. And time to get certified (likely to be 5-10 years) and lawsuits.

    For a couple good examples of conventional aircraft enduring this, look no further than the HondaJet or Leonardo's AW609. Though I am not aware either has been sued, they HAVE taken a very long time to get from design to prototype to test vehicles to certification and sales. Honda worked on their jet for at least SIXTEEN YEARS to get certification, and it's not as radical as a supersonic jet.

    Any new design is going to take years to get certified. Major updates on existing vehicles also take forever. It's just the way it is, and helps keeps these things from falling of of the sky. Which you want even more if the vehicle is supersonic and might kill a lot of people if it failed in flight.

    Mostly, supersonic projects are stuck at the mercy of their engine supplier. There is always only one such supplier and any delays or problems there delay everything else. It's really only recently that some common airliners have even had an option for engine suppliers and you still have to choose in advance who will make them.

  • The key to making this project work is the advanced battery technology described in other Slashdot stories. As soon as those batteries are commercially available, this project will take off.

  • Give us Warp 2.2 and we can talk. Mach 2.2 is just another Concorde.

  • I am old enough to remember when there were a few airliner crashes every year. The improvement since my distant youth came from decades of slogging detail work and accumulated knowledge. That's just the kind of detailed subtle knowledge a start-up company won't have.
