1907 June 4 Tuesday at Baddeck. 61 Telegraph Harrisburgh Pa. 1 Apr 1907 THE AIRSHIP. The theory of the aeroplane is accepted. All that is now required is the motive power that will propel the machine without adding too much to its weight.-Ohio State Journal. Real aerial navigation is the problem on which a great deal of the brains of the world is engaged. Governments are spending money in the promotion of the art or science. It is for the real flying machine on the aeroplane or other principle that the world is looking.-Washington Star. Post Washington D.C. 1 Apr 1907 NEW FORM OF AIRSHIP Johns Hopkins Professor Building Flying Machine. FOLLOWS HELICOPTER TYPE Apparatus with Which It Is Hoped to Solve the Problem of Aerial Navigation Depends Upon Lifting Capacity of Screws to Get into Air-Present Experiments with Steam Power. Baltimore, Md., Mar. 31.-Dr Robert W. Wood, professor of experimental physics at the Johns Hopkins University, and Otto Luyties, a skillful mechanical engineer of Baltimore, hope they have solved the problem in aerodynamics upon which Langley failed and which Santos-Dumont has not yet succeeded in unraveling. Prof. Wood is the successor to the late Prof. H. A. Rowland, the inventor of the famous spectroscope grating machine, known to all physicians, and the multiple telegraph system now being introduced in the various countries of Europe. The type of machine upon which Prof Wood and Mr. Luyties are at work is known as the "helicopter." It is entirely different from the balloon type and belongs to what is known as the "heavier than-air " class of airships, now attracting the attention of all who are interested in aerial navigation. It belongs properly to the same class with the aeroplane, which was the object of extensive experiments by the late Prof. Langley, of Washington. The Langley airship, however, has several drawbacks, the most serious of which is the difficulty of making landings because of the extreme high rate of horizontal velocity which it is absolutely necessary to keep up in order that the ship may sustain itself in the air. Steam as Motive Power. In [sp?] the "helicopter" Messrs. Wood and Luyties hope to overcome these disadvantages entirely. In the first place, there is no stationary supporting surface, such as is required in the aeroplane, which maintains its position in the air by several pairs of huge wings and the high rate of velocity at which it is drawn. Prof. Wood and Lord Rayleigh, the renowned English physicist, differ on the question of motive power. The Englishman advocated electric motors, whereas Messrs. Wood and Luyties show this to be impracticable in that such motors are entirely too heavy, weighing 100 to 150 pounds to the horsepower. Such being the case, Dr. Wood proposes using the steam engine modeled after those used in the racing automobiles. In the particular ship upon which they are now working an engine weighing about 900 pounds and capable of generating 100 horsepower at the beginning will be used. This high horsepower will be maintained for a few minutes only, as it will soon reduce to forty or fifty horsepower, due to the high grade of pressure. The ship is to be lifted by the power of its engine, and movement when in the air will be obtained by what is known as the "lifting powers of its revolving propellers." these propellers will be at least forty feet in diameter and will consist of light metal frames covered with a light but strong fabric. Republic St Louis 1 Apr - 1907 ST. LOUIS'S OFFICIAL AERONAUT ELECTED MEMBER OF FRENCH CLUB [[image]] ALAN R. HAWLEY. HAWLEY DETERMINED TO BECOME EXPERT St. Louis Aero Club Sky Pilot Plans Ascensions at Home and Abroad. KEEN INTEREST SHOWN IN LAHM CUP CONTEST. Result Will Indicate Probable Winner of International Races in October. REPUBLIC SPECIAL. New York, March 31. - Alan R. Hawley, who will pilot the St. Louis entry in the International balloon races at St. Louis next October, received a cable message to-day notifying him of his election as a member of the Aero Club of France. Mr. Hawley is the third member of the Aero Club of America to be elected to the French aeronautic club, the others being Cortlandt Field Bishop, president of the Parent Club in America, and J. C. McCoy, who, with Mr. Hawley, will contest for the Lahm Cup in St. Louis during the latter part of April or early in May. Much interest is now manifested in the coming contest for the Lahm Cup, because of the fact that the two pilots already engaged will represent the St. Louis and New York Eero clubs in the International race in October, and the result of the Lahm contest, in a measure, will indicate the probable winner if the race is won by an American balloon. Mr. Hawley, who will guide the St. Louis machine, is an enthusiast in ballooning and automobiling. He is a member of the brokerage firm of William
