The VanDersarl Blériot: a 1911 airplane homebuilt by teenage brothers (2017)

Here is one in flight, very recently.

  • Very, very cool. Two things I noticed:

    - This is a real rotary engine, where the pistons and cylinders rotate about the crankshaft, and are attached to the propeller

    - The pilot had to keep a constant down angle on the elevator to keep it flying level; was the C.G. right?

  • What an absolutely amazing sight. That turn at 2:30, it's incredible how small the turning radius is, it's going that slow. I could watch that plane soar all day. Thank you for posting this video.

    • Oh, I just realized why it has that very tight turning radius, but only when turning right.

      It's the gyroscopic procession of the majority of engine's mass spinning, in that crazy rotary (not radial) engine!

  • I'm surprised the rear end of the fuselage was an open skeleton instead of being covered like the wings and tail. Wouldn't that significantly interfere with the airflow?

    • It does, but this airplane is so light that it would also upset the balance, even a little weight that far back has a huge effect on where the center of mass is.

It was also two teenagers who, some 50 years earlier, came up with the idea of flying machines and the aerodynamics of wings in the first place:

The brothers Otto and Gustav Lilienthal were watching the storks take flight in the meadows of Mecklenburg in the 1850s. And it made them think, “We could do that, too, if we only had wings like that”.

Of course, Otto died in a crash of one of his motorless flying machines in 1891, I believe. But the Wright brothers saw the eulogy in the paper… and the rest is history.

Reminded me of this book: https://archive.org/details/borednothingtodo0000spie

I'm trying to imagine what a bunch of teenagers could do today to get a similar sense of accomplishment. Note that they weren't even doing particularly well at grade school.

  • My greatgrandmother (born in 1891) left grade school in 6th grade for similar reasons. The real reason she was taken out was "money". (This was rural Indiana about 1903.) She finished her own education through what you might call a master's program by studying her brothers' texts. It was an unwise person who assume her lack of formal education meant anything about her intelligence or informal education.

  • To be fair building an aeroplane today would still be a pretty good sense of accomplishment, although they'd probably get arrested afterwards.

It is so unfortunate that flying has such a credentialist mafia holding it back from more widespread use. Imagine if motorcycles had even half the regulations to ride as single seater aircraft do. Such a ridiculous state of affairs.

  • You don’t think there are any noteworthy differences between a motorcycle and an aircraft in the sort of damage it can do and where?

    • Depends on the aircraft, current ultralights that you don't need to drop $100,000 to get licensed for can only weigh 250 lbs, while motorcycles don't really have a limit and can weight over 1,000 lbs, approaching the weight of a Cessna 152. And when you account for crash scenarios, yeah the rider is at risk in both, but the motorcycle is far more likely to be in and around other people and vehicles during a crash, while a plane is 99% of the time over clear land and even an emergency landing is unlikely to put other people at risk.

      It ain't a perfect comparison, both have problems, but it is far easier to get a license to drive a truck hauling 20+ tons than to get a license to fly a 500 pound plane, and motorcycle licenses is basically a signature and a couple bucks away.

    • A 200kg Kawasaki H2R can go close to 400kph on a two lane road. It is not going to cause any less damage than a single seater falling out of the sky somewhere randomly.

  • Please volunteer then to let inexperienced, unqualified pilots with poorly-maintained vehicles practice flying over your domicile first. This is why flying cars would never and can never work.
