Description:PREFACE.It was in 1856 that I first had my attention called to the subject of flying machines. My father, who was a profound thinker and a clever mechanician, seems to have given the subject a great deal of thought, and to have matured a plan identical with what has been proposed by hundreds since that time. I was then sixteen years of age, and a fairly good mechanician, and any new thing in the mechanical line interested me immensely.My father’s proposed machine, of which he made a sketch, was of the Hélicoptère type, having two screws both on the same axis—the lower one to be right hand and mounted on a tubular shaft, and the top one to be left hand and mounted on a solid shaft running through the lower tubular shaft. These screws were to be rotated in reverse directions by means of a small pinion engaging a bevel gear attached to each of the shafts. His plan contemplated large screws with very fine pitch, and he proposed to obtain horizontal motion by inclining the axis forward. He admitted that there was no motor in existence light enough, but thought one might be invented, and that an engine might be worked by a series of explosions in the cylinder, that is, what is known to-day as internal combustion; but he was not clear how such an engine could be produced. He, however, said that a flying machine would be so valuable in time of war, that it mattered little how expensive the explosive might be, even if fulminate of mercury had to be used. It is interesting to note in this connection that the great Peter Cooper of New York thought out an identical machine about the same time, and actually commenced experiments. It seems that this gentleman regarded fulminate of mercury as altogether too feeble and inert, because we find that he selected chloride of nitrogen as his explosive agent. However, his work was soon brought to an end by the loss of the sight of one eye, after which time he had no further dealings with this lively explosive.The many early conversations that I had with my father on the subject kept the matter constantly before me, and I think it was in 1872, after having seen Roper’s hot-air engine and Brayton’s petroleum engine, that I took the matter up, and commenced to make drawings of a machine of the Hélicoptère type, but instead of having one screw above the other, I saw at once that it would be much better if the two screws were widely separated, so that each would engage new air, the inertia of which had not been disturbed. The designing of the machine itself was a simple matter, but the engine gave me trouble. No matter from what point I examined the subject, the engine was always too heavy. It appears that the Brayton engine was shown at the Centennial Exhibition at Philadelphia in 1876, and that Otto visited this exhibition.CONTENTSIntroductoryAir Currents and the Flight of BirdsFlying of KitesPrincipally Relating to ScrewsExperiments with Apparatus Attached to a Rotating Arm—Crystal Palace ExperimentsHints as to the Building of Flying Machines—Steering by Means of a GyroscopeThe Shape and Efficiency of Aeroplanes—The Action of Aeroplanes and the Power Required Expressed in the Simplest Terms—Some Recent MachinesBalloonsILLUSTRATIONSDiagram showing the reduction of the projected horizontal area,Professor Langley’s experiments,Eagles balancing themselves on an ascending current of air,Air currents observed in Mid-Atlantic,Glassy streaks in the Bay of Antibes,Air currents observed in the Mediterranean,The circulation of air produced by a difference in temperature,Kite flying,Group of screws and other objects used in my experiments,Some of the principal screws experimented with,The three beWe have made it easy for you to find a PDF Ebooks without any digging.
