SANTOS DUMONT AEROPLANE New Machine Ready for Trial Trip in Paris. PARIS, March 11,-Santos Dumont's new aeroplane, constructed to compete for the Duestch-Archdeacon prize of $10,000 for the first "heavier than air" machine to cover a distance exceeding one kilometer and return to the point of departure, is much smaller, more rigid, and more powerful than the "Bird of Prey," with which he won the Archdeacon prize with a flight of 220 metres last fall. In the new machine the canvas of the wings has been replaced by very thin polished wood and the framework of light mahogany.The two wings, constructed like Hargrave box-kites, meet at an angle of eight degrees and have a spread from tip to tip fo thirteen metres. The width of the wings is only sixty centimetrs. A fifty-horsepower motor at the centre will operate a propeller the aluminum blades of which are two metres in diameter. The propeller has been placed in front in the belief that it will have a better grip on the air. Behind and below the motor is the seat for the operator. It is a little more than a tricar saddle, but from it Santos Dumont can direct and maneuvre the apparatus. The helm and steering gear are in the rear, with side rudders on the wings for controlling the equilibrium of the machine. The whole aeroplane weighs twenty kilos less than the "Bird of Prey." It is mounted on a single cycle wheel equipped with an automobile tire, for the preliminary run before the aeroplane mounts. Santos Dumont discarded the two wheels which he used in operating the "Bird of Prey," upon the theory that the less contact with the earthy faster and the straighter the rise into the air. The trials will begin as soon as the ground at St. Cyr is sufficiently hard to give a good running surface. Sun Mail New York 11 Mar 1907.

Eagle Brooklyn. 10 Mar 1907 LIGHT MOTORS THE KEY OF GILLESPIE'S AIRSHIP --------------- Brooklyn Yachtsman Feels He Is Nearing the Hidden Secrets of Aviation. ---------------- THEORETICALLY PRACTICAL. ---------------- An Ingenious Mechanism of Helixes, Gasoline Propelled-Must Float in Air. ---------------- While Brooklyn may not, in the next year or two, make a record for herself in airship construction just that is within the bounds of possibility. A keen Brooklynite, who is an architect and sailor as well, one of the doughtiest tars of the Brooklyn Yacht Club, is going to try to turn the trick. He has some ideas on motors that may help in the solution of this problem. Western capital has come. to his aid, enough to allow a fairly practical demonstration. The Brooklyn yachtsman is no tyro nor crank. He is a hard-headed, successful professional man, who at great cost to himself has already built two airships and seen that they will not work satisfactorily. He is a well-known member of the Aero Club of New York, and at the show of the Automobile Club of America, at the Grand Central Palace, Manhattan, last December, where the Aero Club had space, exhibited the new machines he had already built. G. Curtis Gillespie is one of those men who have the practical determination of the Edisons of this world-he is not to be cast down nor set back because he does not win out, even at the thousand-and-first trial. Flying machines have been a study with him for twenty-four years. He thought he had made a decided advance when he constructed the two airships already noted-aeroplanes that certainly seemed to have some degree of practicability The second one of these was finished two years ago. The Scientific American, on June 24, 1905, thought well enough and seriously enough of the Gillespie Aeroplane to devote two solid pages of pictures and text to it, one of these pages being the front page number. At the motor show of December these two machines attracted great interest and had much to say for themselves along the line of abstract scientific principles. to the point of failure. Here is where Gillespie has been beginning his reform. In his own words the story of what he has already done and what he is meaning to do is most forcibly and best told. "What is wanted," he said, the other day in his office as he pulled out of drawers innumerable fascinating aeronautical records, pictures and articles, collected for over twenty years, "is a motor which will deliver the greatest horse power for the least possible weight, a motor which [?] be so plain, simple and practical as to [?]iliminate in the greatest possible degree [?] likelihood of its being disarranged or operative at a crucial moment. I ha[?] designed such a motor, I think. It will be the first step. "Now, a great many people can make a lightweight motor. But it will be one so delicate and so complex as to be inoperative more than operative. My motor is not that. "It is arranged so that all the parts that [?] are in no sense re[?]active, but entirely rotary, which eliminates the necessity for the added weight of a fly-wheel and obviates the necessary of the starting and stopping of reciprocating parts. In the reciprocal engine the pistons necessarily stop and start at both ends of each stroke, necessitating a loss of power due to the ocvercoming of an inertia. A rotary motor, on the other hand, has trebly-three times the facility for cooling the cylinders that is the case with other motors. "Here is another point. I consider the reliance placed upon one motor in the flying machine problem as a defective feature. Consequently I propose to employ two or more, to obviate the possibility of a failure of the entire motive plant resulting in an accident. "Also, in the flying machine, its method as a means of aviation-propulsion in the air-should not be single, but so to speak, numerous. That is to say, I propose to employ at least three means in on machine to accomplish aviation. These will consist of a number of helixes or screws operating in a horizontal plane, as well as at least two helix or screws operating in a vertical plane, in combination with airplanes or curves; and, further, in case of an entire breakdown of the whole device, furled spars containing a parachute of sufficient proportions to withstand a sudden drop of both machine and operator. "These are, briefly, the main points of my new machine. Its greatest point, outside of the lightness of the motors, will be the factors of safety. Unless a man is safe, remember he has only one opportunity to do the trick, or put it another way, he is taking such chances as to make his experiments impractical. "As to the framework it will be the lightest possible that can be devised. "Here are the calculations on which this machine is being built. The two rotating motors of 17 1/2-horse power each will equal 35-horse power at 2,000 revolutions a moment. The two motors will weigh sixty pounds each, or three and a half pounds for each horse power. A conservative, effective life of 35-horse power at 20 pounds per horse power equals 700 pounds. "Now, the motors will weigh 120 pounds, the sparking device 20 pounds, 4 gallons of gasoline, 25 pounds, 165 pounds in all for the whole motor plant. For 35-horse power for one hour's sus- Red, blue, green or black [[?]] grain morocco leather, soft and fine, and in specially rich colorings, is made up in pocket book style with inside frame, two side pockets and covered button clasp.
