Aerial Steam Carriage


Aerial Steam Carriage

The Aerial Steam Carriage, also named Ariel, was a flying machine patented in 1842 that was supposed to carry passengers into the air. It was, in practice, incapable of flight since it had insufficient power from its heavy steam engine to fly. A more successful model was built in 1848 which was able to fly for small distances within a hangar. The Aerial Steam Carriage was significant because it was a transition from glider experimentation to powered flight experimentation.

The Ariel was to be a monoplane with a wing span of convert|150|ft|m, weigh convert|3000|lb|abbr=on and was to be powered by a specially-designed lightweight steam powered engine producing convert|50|HP|abbr=on.The Fort Worth Press, "Airplane Invention Was Delayed 60 Years", October 11, 1961] The wing area was to be convert|4500|sqft|m2|abbr=on., with the tail another 1500, yielding a very low wing loading.

The undercarriage was a 3-wheel design.

British patent 9478

William Samuel Henson (1812-1888) and John Stringfellow (1799-1883) received British patent 9478 in 1842.

In order that the description hereafter given be rendered clear, I will first shortly explain the principle on which the machine is constructed. If any light and flat or nearly flat article be projected or thrown edgewise in a slightly inclined position, the same will rise on the air till the force exerted is expended, when the article so thrown or projected will descend; and it will readily be conceived that, if the article so projected or thrown possessed in itself a continuous power or force equal to that used in throwing or projecting it, the article would continue to ascend so long as the forward part of the surface was upwards in respect to the hinder part, and that such article, when the power was stopped, or when the inclination was reversed, would descend by gravity aided by the force of the power contained in the article, if the power be continued, thus imitating the flight of a bird. Now, the first part of my invention consists of an apparatus so constructed as to offer a very extended surface or plane of a light yet strong construction, which will have the same relation to the general machine which the extended wings of a bird have to the body when a bird is skimming in the air; but in place of the movement or power for onward progress being obtained by movement of the extended surface or plane, as is the case with the wings of birds, I apply suitable paddle-wheels or other proper mechanical propellers worked by a steam or other sufficiently light engine, and thus obtain the requisite power for onward movement to the plane or extended surface; and in order to give control as to the upward and downward direction of such a machine I apply a tail to the extended surface which is capable of being inclined or raised, so that when the power is acting to propel the machine, by inclining the tail upwards, the resistance offered by the air will cause the machine to rise on the air; and, on the contrary, when the inclination of the tail is reversed, the machine will immediately be propelled downwards, and pass through a plane more or less inclined to the horizon as the inclination of the tail is greater or less; and in order to guide the machine as to the lateral direction which it shall take, I apply a vertical rudder or second tail, and, according as the same is inclined in one direction or the other, so will be the direction of the machine.

Aerial Transit Company

William Samuel Henson, John Stringfellow, Frederick Marriott, and D.E. Colombine, incorporated as the "Aerial Transit Company" in 1843 in England, with the intention of raising money to construct the flying machine. Henson built a scale model of his design, which made one tentative steam powered "hop" as it lifted or bounced, off its guide wire. Attempts were made to fly the small model, and a larger model with a convert|20|ft|m|sing=on wing span, between 1844 and 1847, without success.

The company planned "to convey letters, goods and passengers from place to place through the air", according to the patent.

In an attempt to gain investors and support in Parliament, the company engaged in a major publicity campaign using images of the Ariel in exotic locales, but the company failed to gain the needed investment. There was speculation in the press about whether the Ariel was a hoax or fraud.

Stringfellow's son wrote the following:

My father had constructed another small model which was finished early in 1848, and having the loan of a long room in a disused lace factory, early in June the small model was moved there for experiments. The room was about convert|22|yd long and from 10 to convert|12|ft|m high. The inclined wire for starting the machine occupied less than half the length of the room and left space at the end for the machine to clear the floor. In the first experiment the tail was set at too high an angle, and the machine rose too rapidly on leaving the wire. After going a few yards it slid back as if coming down an inclined plane, at such an angle that the point of the tail struck the ground and was broken. The tail was repaired and set at a smaller angle. The steam was again got up, and the machine started down the wire, and, upon reaching the point of self-detachment, it gradually rose until it reached the farther end of the room, striking a hole in the canvas placed to stop it. In experiments the machine flew well, when rising as much as one in seven. The late Reverend J. Riste, Esquire, lace manufacturer, Northcote Spicer, Esquire, J. Toms, Esquire, and others witnessed experiments. Mister Marriatt, late of the San Francisco News Letter brought down from London Mister Ellis, the then leasee of Cremorne Gardens, Mister Partridge, and Lieutenant Gale, the aeronaut, to witness experiments. Mister Ellis offered to construct a covered way at Cremorne for experiments. Mr Stringfellow repaired to Cremorne, but not much better accommodations than he had at home were provided, owing to unfulfilled engagement as to room. Mister Stringfellow was preparing for departure when a party of gentlemen unconnected with the Gardens begged to see an experiment, and finding them able to appreciate his endeavours, he got up steam and started the model down the wire. When it arrived at the spot where it should leave the wire it appeared to meet with some obstruction, and threatened to come to the ground, but it soon recovered itself and darted off in as fair a flight as it was possible to make at a distance of about convert|40|yd, where it was stopped by the canvas. Having now demonstrated the practicability of making a steam-engine fly, and finding nothing but a pecuniary loss and little honour, this experimenter rested for a long time, satisfied with what he had effected. The subject, however, had to him special charms, and he still contemplated the renewal of his experiments.

*"New Scientist"; 11 October 2003. "It seemed a straightforward bill to put before Parliament: a proposal to allow a new airline to raise funds from investors and operate international air routes to Egypt, China, India and other far-flung destinations. But MPs greeted the proposed Aerial Transit Company with gales of laughter. Mocking prints of its aeroplanes flying over Egypt's pyramids promptly appeared in "Punch" and in the newspapers. What was so funny? Well, perhaps it was the fact that the Aerial Transit Company didn't have any airports to fly from, runways to land on, or aeroplanes to fly in. Or, for that matter, any pilots. But company directors John Stringfellow, William Samuel Henson and Frederick Marriott could hardly be blamed: this was the middle of the 19th century, and aeroplanes had not been invented yet. ..."
