Is it me or is it a military plane ?

  It's a 1/3 scale prototype of their passenger jet.

    It's not a "scale" prototype since it has a different configuration from the passenger jet: https://aviationvoice.com/wp-content/uploads/2016/11/Boom-Technology-Unveils-Supersonic-Demonstrator-1200x900.jpg https://aviationvoice.com/wp-content/uploads/2016/11/Boom-Te... It'd be scale if it was the exact aircraft except every linear dimension was shrunk down. But having a different number of windows, different inlets etc. makes it a smaller concept demonstrator.

      It can still be 1/3rd of the scale, even if it's not a "scale model"
      • carabiner 6y ago
        Not when the configuration is drastically different. "Scale" has a very specific meaning in engineering. It's like saying a motorcycle is a 1/3 scale version of a car just because it uses the same motor. It still demonstrates that the heart of the vehicle works, but it's not a scaled version of it. Here's an actual scale model in aerospace: https://www.youtube.com/watch?v=GHz2B_4g2tM https://www.youtube.com/watch?v=GHz2B_4g2tM

          A motorcycle is not a "1/3 scale version" of a car, but it is "1/3 the scale" of a car (assuming a car is roughly 3 times larger). Scale is not just used in engineering. For example a zoo might have a scale comparison of different animals.

  I see what you mean. I think it's probably a case of 'convergent evolution', where two planes designed for the same sort of thing (size and speed in this case) come out looking sort of similar to each other. The American B-1 Lancer and the Russian Tu-160 look quite similar to each other for instance, but to my knowledge neither is a ripoff of the other.
