JF Ptak Science Books Post 2899
What does “flight” mean, anyway? How much do you have to be off the ground for something to be “flying”? If the answer is “two feet off the ground for 500 feet”, then Hiram Maxim did indeed succeed in being the first to construct a heavier-than-air aircraft that “flew”. Perhaps this definition might be a little broad, or narrow, though it does make falling sound like flying, too.
In any event, that is what Mr. Maxim (1840-1916) did on 31 July 1894 with his enormous aeroplane as reported in the Scientific American of 15 September 1894 ("Maxim's Flying Machine"). He invested a good amount of money in the project funded by his tremendously successful “Hiram gun”, creating a number of aircraft before settling in on a great beast of a flying machine in 1894.
The image of the aircraft is a perspective looking up at it, as though it were in flight. It wasn't, though it was a semi-romantical thought and presentation. It had big numbers: 7000 pounds, 17.5' diameter propellers, 2 steam-powered 180hp engines, 120' long and 105' wide, and 8” cylinders with a 5” stroke. Big numbers.
One of the images that really struck me though was the steam chamber, which looks absolutely huge (though I can't find dimensions for it), but you can make it out on the aircraft's bow. For test runs 600 pounds of water were needed—2500 pound were needed to generate lift.
So back to the “flight” issue; Mr. Maxim was on board the 3-person-crew aircraft on the day of the test. The aircraft was tethered to an 1800' wooden rail to prevent it from actually taking off if it could...I think mainly because they were really just testing lift, as controlled flight was still yet another enormous issue. The aircraft did manage to achieve lift two feet above the rail, but the force was so great it ripped up the rail and crashed. (Mr. maxim found himself in a somewhat similar position to that of Frankenstein when overpowered by the monster which he himself had fabricated and endowed with life.") No one was hurt, though the aircraft was decimated. As the writer in the Sci Am stated, "the ride in this way was brought to a sudden stop, and it will be several months before it can be renewed". It isn't anything like the Wright's flight nine years later, though some do consider this Maxim experiment to constitute a “first flight”.
One thing is certain: it was a lovely and impressive thing that Maxim built--it wasn't elegant by any means, though it had a certain crushing charm to it.
Here's a photo of the aircraft (with a person standing right there in front of it, for scale):
