NASA and Lockheed Martin formally debuted the agency’s X-59 quiet supersonic aircraft Friday. Using this one-of-a-kind experimental airplane, NASA aims to

            I agree. But sadly, a lot of progress is driven buy conflict as well.

            Unless a nation is under an existential threat there is little motivation to invest in progress.

    If they are taking about an “X-59” it’s because the classified tests on the “X-109” went well.

    Guys, check out the cockpit.

    I know technology is wildly advanced and he probably has a 360 view now, but other than test pilots, who are you going to get to fly a plane that lacks a forward view?

      One of the material issues with supersonic is friction heat buildup. Probably can’t have a front windshield at that speed.

      Cameras and instrumentation will do just fine tho

        The heat is from compression, not friction. And besides that, this thing is only flying at mach 1.5, there are TONS of aircraft that fly at those speeds (and much faster) with windshields.

        The reason it doesn’t have a front windshield is because the change in shape of the aircraft at the windshield, to be more vertical, was disrupting their method of reducing the sonic boom. The aircraft needs the shape it has, so a windshield would have to be like 20 feet long to offer any forward visibility.

      This plane will only be flown by test pilots. Its a technology demonstrator. Researchers build one of these to test concepts in physics in the real world.

    “Across both teams, talented, dedicated, and passionate scientists, engineers, and production artisans have collaborated to develop and produce this aircraft,” said John Clark, vice president and general manager at Lockheed Martin Skunk Works.

    What the hell is a production artisan?

      Someone with the skills and knowledge to “manually” produce some of the many one-off parts that went into this prototype.

      The scientists and engineers may know what kind of part is needed, but it takes a different skillset to produce it.

        So like the welders for the Russian rocket engines that were produced 50 years ago? Seems those welds are something we aren’t sure how they did it.

          Yeah something like that. Welding is absolutely something that requires skill and talent.

          I have a electromechanical engineering degree myself, at some point during my education we had some labs where we did basic welding, milling, lathing and whatnot. The intention was not to become experts at it, but to get notions of what it entails. I quickly understood that theoretical understanding and hands-on experience are entirely different things, and require an entirely different skillset.

        A sonic thump could still be very disturbing. Maybe not break windows, but induce panic I a lot of people.

          Yeah, apparently we do…

          The problem with Sonic booms isn’t that you notice them, it’s fine to notice the sound of a vehicle traveling overhead. The problem is that the sound from previous supersonic jets has shattered windows all along the flight path, ruptured eardrums and caused moderate hearing loss.That is a problem…

          If this instead sounds like a car door closing, I’d call that significantly quieter.

            I was at work in a bank (big, sturdy, multiple stories) when we experienced a sonic boom. It was heard/felt across several counties. We thought a bomb had gone off somewhere.
