Part 2

Now, as a striking contrast, let us turn to the reception which early enthusiasts received in other countries. Let us take France, for example. Ader, an electrical engineer, devised, in 1896, a very ingenious, bat-like aeroplane. With it, having fitted a small steam-engine, he actually achieved a short flight—or, rather, a brief "hop" from the ground.

Instead of being greeted apathetically, or having his sanity doubted, Ader was promptly called to appear before the military authorities. They, after hearing his theories expounded, cheerfully voted him £20,000 in order that he might continue his experiments upon an adequate scale. Thus, even at this early stage, France revealed her keen interest in aerial navigation. Ader, lacking the petrol motor, could not carry his investigations much further. But the encouragement he received gave heart to other inventors. And so France went forward to success.

America offers another example of a sane, far-seeing policy. Professor Langley, an eminent scientist, was making a series of wonderfully interesting model aeroplanes at about the time Ader was experimenting in France. To further his work, the American authorities very promptly came forward with a grant of £10,000.

He, like Ader, was unable to carry his individual experiments to a successful issue; but further investigation, on the part of other workers, was greatly stimulated. It is interesting to note what position these two countries, which first encouraged flying, afterwards took when the aeroplane became a reality.

To America, in the work of the Wright brothers, has gone the honour of the first practical flights with a heavier-than-air machine, while France is to-day the premier nation in the world in the development of airmanship.

Thus it is legitimate to pass to a consideration of the first machines that flew, and consider their capabilities from the military point of view. The Wright biplane, naturally, is the first to attract attention, because it was as long ago as 1903 that these two quiet, determined Americans made their first successful flights. From a military aspect, this aeroplane had many drawbacks; and to cite them is instructive, seeing that, by this means, a reader will be better able to judge, later on, what vast strides towards perfection the aeroplane has already made.

The first Wright biplane would, indeed, just fly; that was all. Its pilot only dared to leave the ground when an absolutely dead calm prevailed; he feared the overturning influence of even the smallest gust of wind. His engine, being then a novelty as applied to the aeroplane, required the most patient "tuning up" before even a brief flight could be essayed; and, when it was aloft, the machine only passed through the air quite close to the ground.

Each flight had to be started by sliding the aeroplane forward along a rail; away from this rail, the machine was helpless. From the point of view of a military expert, indeed, this early machine could have been condemned upon several counts. It was unreliable. It could not fly in gusty winds; it was not portable; it could only take the air when launched from its rail.

But the true expert is far-seeing. He makes light of present imperfections if, in any idea, he can see future developments of undoubted importance. Such an expert, for instance, was the late Captain Ferber, of the French Army. He was the first military officer to whom the task fell of reporting, for his Government, upon the capabilities of a military aeroplane.

Representations were made by the Wright brothers to the French Government in the year 1905—two years after their first flights. They had improved their machine considerably; they were now ready to carry a passenger; and they wished to sell their secret. So Captain Ferber was instructed to go to America and investigate their claims.

The Wrights were anxious to sell their secret for a lump sum of money. They had begun their experiments in the humblest possible way, being small cycle-makers at Dayton, Ohio; and they were unable to protect, by patents, the machine which they had evolved by so vast an amount of patient work.

Thus they sought to enter into negotiations with some Government. They asked for a guarantee that their machine would be bought, for a certain price, were it to perform a series of stipulated flights. Their position was, as a matter of fact, a somewhat awkward one. Even a brief examination of their aeroplane, by an expert, would have revealed its principle.

In this quandary, they were led to approach the French Government. They chose France for a very good reason. Already, as has been indicated, this country was keenly alive to the possibilities of flying. The two brothers imagined, therefore, that they would be able to make their best bargain with the French Government.

The practical interest which the French authorities took in the question of military flying was evidenced by their action when they received a communication from the Wright brothers. Although reports of the Wrights’ experiments had been greeted, in Europe, with great scepticism, and there was reason, in view of the failure of other inventors, to doubt their claims, the French Government at once detailed Captain Ferber to make the long journey to Ohio, so as to go into the matter in a business-like way.

Captain Ferber, who was one of the first officers in France to become actively interested in airmanship, duly visited America, and interviewed the Wright brothers. They could not show him their machine. Had they done so, their secret would have been revealed. Regarding the flights which they had made, up to this time, Captain Ferber had to rely, for testimony, upon the statements of certain responsible men living in Dayton, who had witnessed them.

The position, so far as he was concerned, was rather an unsatisfactory one. It was like buying "a pig in a poke." But this officer, being a student of character, and an enthusiast regarding flight, saw what manner of men these two brothers were. He did not doubt their word, nor the statements of those who had seen them fly. So, when he returned to France, he recommended his Government to enter into negotiations with the Wrights, and buy their invention before any other nation took steps to secure it.

It was a tribute to his foresight that he should have done this; but, for the time being, the negotiations fell through. The Wrights, for one thing, wanted a very considerable sum of money; and there was difficulty, also, in arranging what the series of tests of their aeroplane should be. Thus it was that, after many communications had passed between the interested parties, the matter stood in abeyance.

In the meantime, however, other inventors were striving with the great problem. In France, in 1906, Santos-Dumont effected "hops" with a machine like an exaggerated box-kite; and this led the way to the remarkable achievements of two particularly clever brothers, Charles and Gabriel Voisin. They busied themselves with a biplane which, at the end of 1907, they asked Henry Farman, a well-known racing motorist, to test for them.

This led to the first famous flights of the Voisin machine at the military parade-ground of Issy-les-Moulineaux, outside Paris. France went wild with enthusiasm when this big, clumsy machine, piloted by the quick, agile Farman, succeeded in flying for a mile, and in making a turn while in the air.

The Voisin aeroplane needed to run along the ground for quite a hundred yards before it could gain sufficient support from the air to enable it to rise. When it did so, it was only just able to skim along above the ground. Compared with present-day aeroplanes, it was an unwieldly, unsatisfactory machine; and, to make matters worse, its motor became overheated after only a minute or so’s running.

As a machine for military purposes, it would have been useless. But it represented a definite stage in the progress of aeroplaning. From this machine of the Voisin brothers, which Farman first flew, developed the great school of biplane construction in France.

Also experimenting in France, at the same time as the Voisin brothers, was another great master of flight—M. Louis Blériot. His methods were original. He pinned his faith to the monoplane.

II. First practical flights—The Wright brothers; the Voisins; Farman—The cross-Channel flight.

Hastening our review, in order to reach matters of more definite interest from the military point of view, we find that, in 1908, the Wright brothers made aerial history by a series of magnificent flights which were, however, unfortunately marred by a tragedy.

Coming to France, Wilbur Wright flew for a couple of hours, without descending, at Le Mans. At about the same time, in America, Orville Wright was carrying out a series of demonstrations before the military authorities. He achieved remarkable success, particularly from a war point of view, by carrying a passenger in his machine for quite a long flight.

Then, when taking up Lieutenant Selfridge, of the American army, he met with disaster. One of the propellers of his machine broke; it crashed to the ground from a height of about 100 feet. Lieutenant Selfridge was killed, being the first victim of the aeroplane, and Orville Wright broke his thigh. The accident, as may be imagined, cast a gloom over flying in America for a long time.

Longer flights by Henry Farman, on an improved Voisin biplane, were also to be noted in the year 1908; and thus the way is cleared for a description of the wonders achieved in 1909, when it may be said that the importance of the aeroplane, from a military point of view, was first demonstrated, and the attention of nations seriously directed towards the possibilities of this new "arm."

Early in the summer of 1909, after innumerable disappointments, and the breaking-up of many experimental machines, Blériot began to achieve success with a simply-constructed monoplane, driven by an equally simple three-cylinder petrol motor; and, at the same time, another French monoplane, the Antoinette, larger than Blériot’s, and having an eight-cylinder motor developing sixty horse-power, was also flying surprisingly well.

It was in July, 1909, that these two machines, representing a distinct type, when compared with the biplane, were brought down to the French coast at Calais with the intention of invading England by air, and winning a prize of £1000 offered by the _Daily Mail_. Piloting his small monoplane was M. Blériot himself, while the Antoinette was flown by Mr Hubert Latham, an airman already famed for his daring.

The method of Blériot’s arrival at Calais gave promise of the eventual utility of his machine from the military point of view. The two wings of his monoplane could easily be detached. They were then folded on either side of the body of the machine; and, thus dismantled, it could be placed for transport upon an ordinary railway truck.

In this fashion it reached Calais, greatly to the surprise of those who had, hitherto, only been familiar with the huge cases needed for the transport of biplanes. When taken from the railway van, the monoplane was tied with ropes behind a motor-car, and ran upon its own pneumatic-tyred wheels to the shelter prepared for it near the sand-hills of Les Baraques, a mile or so from Calais.

Blériot, as history records, won the £1000 prize by flying across the Channel from France to England, just after the dawn on 25th July, 1909. He landed near Dover Castle, after a flight of thirty-seven minutes. Latham, unfortunate with his engine, made two attempts at the crossing, but fell into the sea on both occasions.

Blériot’s feat made a deep impression upon all thoughtful men, and particularly upon the military authorities in France. If such a flight could be achieved with a small, crude machine, what might not be possible with a perfected apparatus? This, naturally, was the question which was asked.

In the next important demonstration of the possibilities of flight, which was made at the Rheims flying meeting, held in August, 1909, the French Government took a very active interest. They sent special representatives to this meeting—the first of its kind—to study the various types of flying machines which took part in the contests organised. As a further instance of the practical ideas already being displayed by military men in France, it may be mentioned that one of the competitors at this memorable flying meeting was the French officer whose work has previously been mentioned—Captain Ferber. He flew a Voisin biplane. It was not, unfortunately, very long after the Rheims meeting that this enthusiastic military airman met with his death at Boulogne, his loss being sincerely mourned by the French Government. His biplane overturned in a ditch, and he was killed by the heavy motor, which was torn from its bed, and fell upon him.

III. Aeroplanes at Rheims, 1909—Wright, Voisin, Farman, Blériot, Antoinette—The Gnome engine—First military orders.

Seeing that the Rheims meeting of 1909 was the first occasion upon which a definite military inspection of aeroplanes was made, it should be interesting to describe the machines which were then available. Let us take, for example, the Wright biplane, of which we have previously spoken. This machine, as piloted at Rheims by Lefevre, Tissandier, and the Comte de Lambert, undoubtedly proved itself one of the best all-round machines then in existence.

The aeroplane represented the usual biplane form of building, having one sustaining plane fixed above another, the two being held apart by wooden struts, made taut by cross-wiring.

In front of these main-planes, upon outriggers, was a small double-plane elevator. At the rear of the main-planes, also carried upon outriggers, was a double-plane vertical rudder. The engine of the machine, set upon a wooden bed on the lower plane, actuated two wooden propellers, which—driven by chains—revolved in opposite directions behind the main-planes.

The pilot’s seat was on the front edge of the lower main-plane, and his control of the aeroplane, when in flight, was effected by means of two levers. One, moved forward and backward, actuated the elevating planes, and the other was given a dual motion. Moved to and fro, it operated the rudder of the aeroplane. Shifted from side to side, it warped the rear extremities of the main-planes, and so controlled the lateral stability of the aeroplane.

This wing-warping mechanism was, as a matter of fact, one of the salient features of the Wright biplane. The system is considered to be the most efficacious method of combating the effect of wind-gusts when an aeroplane is in flight.

In operation, this wing-warping device was simple. When the airman discovered that his machine was tilting over one side, owing to a sudden inequality in wind pressure, he quickly warped down the plane-ends on the side of the biplane that was depressed. The result was that there was increased wind-pressure under the plane-ends warped down, thus tending to force the machine back again upon an even keel.

The pilot who distinguished himself greatly at Rheims, when flying the Wright biplane, was Lefevre; but this daring airman was, unfortunately, killed shortly afterwards at Juvisy, when testing a new machine. At Rheims he circled in the air, and effected sharp turns, in an altogether remarkable way, demonstrating an absolutely complete control over his machine. So impressed were the representatives of the French Government by the performance of the Wright biplane, that they ordered several machines for military use. This represented their first definite order for aeroplanes for war purposes.

The chief drawback of the Wright biplane, in comparison with other machines flown at this time, was that it needed to make a start into the air from a launching rail, as has previously been mentioned.

The advantage of this system of starting—in which a weight, dropped from a derrick, gave the aeroplane its initial impetus along the rail—was that the machine could be fitted with a lower-powered engine.

But the disadvantages were obvious. Were an involuntary descent made at a point some distance away from the machine’s rail, it had to be carted back to the starting-point, or a rail and derrick brought to the place where it lay. However, the French Government did not regard any aeroplanes at this time as representing serviceable war weapons. They took the wise view that they were purely instructional craft, upon which military airmen could gain experience, and so fit themselves for the use of the more perfect machines which were likely to be evolved as time went on.

After describing the Wright biplane, we may now consider the Voisin machine. This aeroplane represented an improvement upon the type first piloted by Farman at Issy-les-Moulineaux. It had two main supporting planes, like those of the Wright biplane, fitted one above another. In front of the main-planes was a single horizontal elevating plane. At the rear of the biplane was a large cellular stabilising tail, made up of horizontal and vertical planes, and resembling a box-kite. In the centre of this cellular tail was the rudder, a single vertical plane.

Instead of adopting a wing-warping device, for maintaining lateral stability, the Voisin brothers fitted vertical planes, or curtains as they were called, between their main-planes. These, when the machine was in flight, resisted any sideway roll and, in conjunction with movements of the rudder, gave the aeroplane a certain amount of automatic stability.

The biplane rested upon a chassis made of hollow metal tubing. It had pneumatic-tyred bicycle wheels, mounted in connection with heavy springs, to resist the shock of landing after a flight. Small wheels bore the weight of the tail when the aeroplane was running along the ground.

An engine of sixty horse-power, fitted upon the lower plane, drove a two-bladed metal propeller, placed behind the main-planes. The pilot, seated midway between the planes, operated a wheel like that of a motor-car. He pushed it away from him, or drew it back, to operate the elevating plane, and turned it sideways to actuate the rudder.

This machine had the advantage over the Wright biplane that it was not dependent upon a starting rail. But, in general comparison with the Wright machine, it was heavy and sluggish. It required a long run before it would lift into the air, and its engine-power, although twice that of the Wright biplane, was only just sufficient to make it fly. In a side wind, owing to the influence which the gusts exerted upon the vertical panels which were fitted between the main-planes, it made an appreciable amount of "lee-way," which rendered steering difficult.

Altogether, regarded from the point of view of experts to-day, it was a heavy, awkward machine. But it flew, and flew steadily. And anything that flew, in the year 1909, represented a triumph. Several famous airmen were piloting the Voisin biplane at the Rheims meeting, notably M. Louis Paulhan and M. Rougier.

From a military aspect, the Voisin biplane had many drawbacks. It was not at all portable; it could not rise quickly; it was slow-flying. But, with the very laudable intention of encouraging such ardent pioneers as the Voisin brothers, the French Government gave orders for certain military machines of this type.

Now we may turn to what was undoubtedly the most successful biplane at the great Rheims carnival—that designed and flown by Mr Henry Farman. This famous airman had, it will be remembered, first learned to fly upon a Voisin biplane. After piloting this machine in 1908, he turned his attention, early in 1909, to the design of a biplane which should be lighter and more efficient.

In this endeavour, he certainly succeeded. The biplane which he first flew in public at the Rheims meeting represented a distinct step forward in the development of this type of machine. In general construction, it was lighter than the Voisin machine, and it had other excellent features as well. Instead of the heavy, cellular tail, as fitted to the Voisin biplane, it had a lightly-constructed tail made up of two horizontal planes, with a vertical rudder fitted between them. In front of the main-planes, upon light wooden outriggers, was placed the horizontal elevating plane.

One of the features of this machine, was its method of obtaining lateral stability. Farman recognised the disadvantages of the vertical planes, as used in the Voisin machine. So he fitted small flaps, or horizontal planes, at the rear extremities of his mainplanes. These were hinged to the main-planes, and were termed "ailerons."

Their operation produced the same result as in the application of the wing-warping device of the Wright brothers. When the biplane tilted sideways in flight, the "ailerons" were drawn down, by means of controlling wires, on the side that was depressed. The air pressure, acting upon the surfaces of the "ailerons," forced the aeroplane back upon an even keel. When not in operation, the "ailerons" flew out straight in the wind, on a level with the main-planes.

The control of the Farman biplane was effected by means of a hand and foot lever. The hand lever, when moved forward or backward, operated the elevating plane. When shifted from side to side, it actuated the "ailerons." The pilot’s feet rested upon a pivoted bar, which he swung from side to side to move the rudder of the machine.

Another constructional feature of this first Farman biplane was notable. This was the landing chassis. Appreciating the disadvantages of the Wright launching rail, and recognising that the Voisin chassis was heavy, Farman aimed at something lighter, and at the same time more efficient.

Again he succeeded. He devised a chassis which was a combination of wooden skids and bicycle wheels. Below his biplane, upon wooden uprights, were fitted two long wooden skids. On either side of each skid, were two little pneumatic-tyred bicycle wheels, connected by a short axle. The wheels were held in position on the skid by stout rubber bands, which passed over the axle.

Normally, the skids were raised off the ground by the wheels, upon which the biplane actually ran. But, in the case of a rather abrupt descent, the chassis was so designed that the wheels were forced up against their rubber bands, thus allowing the skids of the machine to come into contact with the ground. Then, when the force of the shock had been absorbed, the wheels came into play again. With this biplane, Farman achieved fine flights at Rheims.

Apart from its constructional excellence, the biplane was fitted with a motor which was destined to have a remarkable influence upon the development of flying—and upon military aviation in particular. This was the seven-cylinder, revolving "Gnome." To-day, the application of this wonderful engine is practically universal. In August, 1909, it was regarded quite as a freak, and was seen for the first time upon Henry Farman’s biplane.
