It is reported that Lieutenant Lahm, U.S.A., who last year won the international balloon race at Paris, will be detailed at Fort Leavenworth to take charge of the experiments in aeronautics to be carried on by the Government. The war balloon, now being constructed in the East, is expected to be finished and to arrive at the fort some time next month, when experiments, not only in aeronautics, but also in signalling from balloons and in testing the balloon as an aid in wireless telegraphy, will be begun. Major George O. Squier, assistant commandant of the Signal School for the army at Fort Leavenworth, is to have charge of the latter. Lieutenant Lahm, who is an officer of the Sixth Cavalry, is now in France, where he is to compete in other balloon races, then take part in the St. Louis races and shortly thereafter come to the fort for permanent station. The balloon now being made in Washington, D.C., by Lee O. Stevenson, one of the most noted aeronauts of the country for the army, is to be the largest ever constructed in the United States. The bag will be sixty-five feet in diameter and will hold 28,000 cubic feet of gas. It will lift over a ton, and the basket will hold fifteen men. this basket will be six feet long, five feet wide and four and one-half feet high. The Signal Corps of the army is especially interested in ballooning at this time. The company stationed at Fort Leavenworth has made more advanced strides in wireless telegraphy than any other company of the army, yet there has been much difficulty in getting the wires sufficiently high into the air to get good results. With the big balloon it is expected that the company will be able to communicate with all portions of the United States. The corps will also use the balloon in the study of military signalling to be used in army maneuvers. -- Wellman's Dirigible Balloon The Aeronaut Describes the Airship in Which He Will Seek the North Pole. Walter Wellman, who is conducting the Chicago Record-Herald's expedition, which is to seek the North Pole by airship, this summer, describes his vehicle, the America, as follows: The airship America is composed of two distinct parts. one is the gas reservoir or balloon; the other, the car and mechanical part suspended underneath it. As to the first, it is commonly called the balloon. It is a balloon, in a sense, but we dislike to use the word, because it gives some people the idea that we are going to try to reach the North Pole in a balloon- a mere spherical, drifting balloon, a toy of the winds, such as the unfortunate André used. Needless to say, it is not a balloon we are employing. But an airship is quite a different thing from a balloon. It is something more than a toy of the winds. it has propulsive force. It can fight the winds. It can go against them, if they are not too strong. It can steer to the right or the left. It is within its limitations, a true ship of the air. it is more like a steamship, while a balloon is nothing but a raft- not even a sailing vessel, that can beat up against the wind, and tack, and get somewhere. The gas reservoir of the America is a pretty large affair. In its present state, as enlarged for the campaign of 1907, it is 183 feet in length. Place thirty such ships end to end and they would stretch out more than a mile. its greatest diameter is 52.5 feet- something like the height of four--- (//). The surface of the envelope {{END OF PAGE}} tres, the weight of the air is 21,430 pounds- more than ten and a half tons. If we put into the reservoir hydrogen gas of good quality, almost but not quite pure, we find that the weight of the gas is 1875 pounds. Inasmuch as the weight of the air displaced is 21,430 pounds, the lifting force when inflated with hydrogen is 19,500 pounds. In other words, so inflated the ship would lift nearly ten tons, including, of course, its own weight. And as the reservoir itself and its immediate appurtenances weigh about two tons, we are able to attach to it a weight of more than seven and a half tons, and leave it still enough buoyancy to rise in the air. The mechanical part suspended underneath is built on an equally large scale. Last year the car was of a combination of iron and wood- a wooden framing reenforced by iron strips. that car has been entirely discarded. In fact, we did not even take the trouble to bring it back from Spitzbergen. We have built an entirely new car-- this time wholly of steel tubing. The old car was fifty-two feet long, the new one is 115 feet long. These tubes are very slender-- the heaviest only a little more than an inch and a half in diameter, and most of them are smaller still. But the steel is of finest quality, and the tube is a wonderful form for strength and rigidity. the completed structure looks somewhat spider-webbish, but it has the stiffness and endurance. It is V-shaped, the point of the V down. From top to bottom it is eight feet; and the top width is five feet. At the bottom of the V is something that was never before seen in airship construction or anywhere else, we believe. It is an illustration of the manner in which we have tried to economize our weight-- to make one thing perform two or more services. We wanted to carry in the airship nearly 7000 pounds of gasolene for the motor--1150 gallons. to put all this fluid in small tanks would require about a thousand pounds of tanks since they must be strong, tight tanks, sure not to leak. We did not much like the idea of giving up half a ton of our precious weight to mere tanks, unless after the gasolene was taken out of them. Was it not possible to utilize this weight to better advantage? We solved the problem by making a steel tank eighteen inches in diameter and 115 feet in length-- running the whole length of the car-- and putting it at the bottom of the V. where it is not only a storage tank but an integral part of the car itself giving strength and rigidity to that structure. the weight of this somewhat remarkable steel tank is about 1000 pounds, or almost exactly that w should have been compelled to put into the small tanks we originally.. {CUT OFF AT END OF PAGE}} ... can reach with his hand the valves and other adjuncts of the gas reservoir, which might be important in case of any derangement in the field. The car is enclosed, sides up and top, with oiled silk stretched taut. Of course, these were windows for observation purposes. The forward sections of the steel car are built stronger than the rear part. These sections are triangular, and possess great rigidity in proportion to their weight. This is because they contain the engines and carry the screws, therefore they must be able to withstand the vibration. In the centre of this triangular structure is placed the motor of sixty to seventy horse-power. The driving shaft runs right through the engine, across the car, and at each side is a steel screw eleven and a half feet in diameter. One screw turns in one direction and one in the other, the gyratory effect of one being counterbalanced by that of its mate-- a great advantage over the old way of placing a screw forward or aft, its revolutions being sure to get up a twisting motion liable to do damage to the structure. Turning at its normal speed of 1000 revolutions per minute, the screws turn about 300 per minute, and the speed imparted to the airship is approximately seventeen statue miles per hour-- fifteen knots, or geographical miles. In the section immediately forward of the one containing the sixty to seventy-horse-power motor, the fire-horse-power motor and the other machinery-- the engine-room of this aerial cruiser-- is the nevagating deck, where the ship is to be managed. In the section aft the engine-room is the cabin of the crew, with sleeping bunks and a little cook stove. At the extreme rear is the rudder which steers the craft to the right or left and nearby are movable planes placed horizontally-- rudders for pointing the nose of the craft upward or downward, all manipulated, of course, from the navigating deck. Extending out from the top of the car are spreaders, which carry a wide expanse of silk stretched taut forming a large permanent horizontal plane designed to steady the ship in her progress through the air, averting much of the "tangage" or pitching and rolling to which most airships are subject and which retard speed. An airship, like any other ship, should be properly loaded. Her cargo must be well distributed. The bulk of our load is the fuel carried in the long tank at the bottom of the car where its weight is well placed for securing stability. this fuel we can draw from any section we like, this trimming the ship. Moreover, Chief Engineer Vaniman has arranged an ingenious device in the form of a little overhead railway which carries a suspended car contain- [[CUT OFF]] principles balloon s In my de "The s shape,' as I have my resistance down to a My airshi and the g enteen fee main body be forty f the edges Seventeen loon.' in feet wide balloon b side of the feet from rents plent so that tw and force this main balloons o tubing mac edge. the suspended an aluminu "Over th 'canopy' ba long by for in the cen and divided the lower se thick at all will be pla total of two a sudden fa "Directly be two drivi width, as sa will be two side.
