Here's a wonderful and short editorial comment from the Scientific American on the possibilities of human flight, coupled with the observed fruitless pursuit of perpetual motion machines. There wasn't much hope expressed in flight, but "the end of flying machines is not yet" and the author shares a vision for one possible flying machine, which was a huge, steam-driven, wrought iron 40' x 8' design with between four and twelve wings. No mention is given of its weight.
"Flying Machines", in Scientific American, December 23, 1848, vol 4, #14.
“Flying Machines and Perpetual Motions are very old and unfortunate acquaintances. No people have invented so many as the Germans, and many a poor fellow has lost his life by his fool hardy confidence in some machines he had invented to ride upon the winds, yet for all the accidents that have taken place to high flyers, from the Dutch Doctor at Ratisbone in 1692 to the unfortunate Englishman who perished a few years ago in London when descending by a parachute, there are still to be found new flying machines coming out every few months.”
“But the end of flying machines is not yet, and here we insert the description of a new and an original one certainly, taken from the Jacksonian published at Pontiac, Michigan…”
“As wings then, have failed, and balloons been attended with no better success, men have begun to think that the end is unattainable, and that flying is a victory which man can never achieve. The art of flying simply consists in the suspension and motion of a heavy body in a lighter. Although this may appear contrary to the nature of things, it is what takes place every day, and is seen exemplified in the case of every insect and bird that flies—all of which are heavier than the air.”
“Let us suppose a machine to be constructed resembling a long railway car, with arms projecting at certain distances from the roof and floor, appearing like the long axles of a wagon wheel. At me extremities or these arms the axles of the screw wheels or wings are inserted, which thus work parallel to the earth, instead of perpendicular, as in a vessel. At the stern of the car are from two to four wheels, to serve as propellers, the side wheels being merely to elevate and suspend the car. In the interior of the car, at the centre, is the steam engine, with the fuel and water, while the extremities are reserved for passengers and baggage. The wings are moved by independent bands connected with the internal machinery, so that the whole or a portion of them may be used at once, for the convenience of ascending and descending.”
“This machine instead of having two wings like a bird, will have from four to twelve, according to the length. The forward end should be built sharp, to offer less resistance to the wind. Having more wheels than are necessary to its elevation, no danger can occur from any accident that may occur to one or two of them. The machine can be guided by some kind of rudder, or by stopping one or two of the stern wheels, which are attached to each side of the stern. At first sight, such a machine as this may appear the production of a visionary, but the same would have been said fifty years since had any man described a locomotive engine and a railway. Every step towards the construction of this machine can be based on mathematical principles The air furnishes a vast fund of power for the use of mankind, although as yet they have only used it to propel ships and wind-mills. “
“A car forty feet long, with five wheels on each side, eight feet in diameter and three smaller propellers at the stern, would certainly appear a novel object, when roaring along through the air. If a certain breadth of wheel be not sufficient, try broader ones—if the velocity be too slow, increase it.”
“We however wish the inventor success—but before he proceeds to construct his machine we hope he won’t forget the law that was discovered by the great Newton in the falling of an apple.”
