Bây giờ là tôi có nó, bước tiếp theo của tôi sẽ là máy bay hoàn hảo." "Một máy bay lái xe của động cơ của bạn?" Tôiyêu cầu. "Không phải ở tất cả,", ông tiến sĩ Tesla. "Máy bay là khiếm khuyết không lành. Đó là chỉ đơn thuần là một đồ chơi--một đồ chơi thể thao. Nócó thể không bao giờ trở thành thực tế thương mại. Đô thị này có Khuyết tật nghiêm trọng. Một là một thực tế rằng khi nó gặp mộtxuống hiện tại của máy đó là bất lực. Lỗ' trong không khí các' trong đó phi công nói là chỉ đơn giản là một xuốnghiện tại, và trừ khi máy bay là cao đủ trên trái đất để di chuyển sang hai bên nhưng có thể không phải làm gì nhưng rơi."Không có không có cách nào phát hiện các dòng xuống, không có cách nào của họ, và do đó chiếc máy bayluôn luôn phải tùy thuộc vào cơ hội và nhà điều hành để nguy cơ bị tai nạn chết người. Động viên thể thao sẽ luôn luôn cóCác cơ hội, nhưng như là một đề xuất kinh doanh rủi ro là quá lớn."Máy bay của tương lai--của tôi máy bay--sẽ nặng hơn không khí, nhưng nó sẽ không là một máy bay. Nósẽ có không có cánh. Nó sẽ là đáng kể, vững chắc, ổn định. Bạn không thể có một máy bay ổn định. Có thể con quay hồi chuyểnkhông bao giờ được áp dụng thành công để máy bay, vì nó sẽ đưa ra một sự ổn định sẽ cho kết quả trong máybị xé ra từng mảnh bởi gió, cũng giống như máy bay không được bảo vệ trên mặt đất là rách ra từng mảnh bởi caoGió. "Máy bay của tôi sẽ có cả cánh và cánh quạt. Bạn có thể nhìn thấy nó trên mặt đất và bạnsẽ không bao giờ đoán rằng nó là một máy bay. Nhưng nó sẽ có thể di chuyển sẽ thông qua không khí ở bất kỳdirection with perfect safety, higher speeds than have yet been reached, regardless of weather and obliviousof 'holes in the air' or downward currents. It will ascend in such currents if desired. It can remain absolutelystationary in the air even in a wind for great length of time. Its lifting power will not depend upon any suchdelicate devices as the bird has to employ, but upon positive mechanical action.""You will get stability through gyroscopes?" I asked. "Through gyroscopic action of my engine, assisted bysome devices I am not yet prepared to talk about," he replied. "Powerful air currents that may be deflected atwill, if produced by engines and compressors sufficiently light and powerful, might lift a heavy body off theground and propel it through the air," I ventured, wondering if I had grasped the inventor's secret.Dr. Tesla smiled an inscrutable smile. "All I have to say on that point is that my airship will have neither gasbag, wings nor propellers," he said. "It is the child of my dreams, the product of years of intense and painfultoil and research. I am not going to talk about it any further. But whatever my airship may be, here at least isan engine that will do things that no other engine ever has done, and that is something tangible."The Tesla PumpLooking out over the city from the windows of his office, on the twentieth floor of the Metropolitan Tower, hisface lit up as he told of his life dream and its approaching realization, and the listener's fancy could almostsee the air full of strange flying craft, while huge steamships propelled at unheard of speeds plough thewaters of the North River, automobiles climbed the very face of the Palisades, locomotives of incrediblepower whisked wheeled palaces many miles a minute and all the discomforts of summer heat vanished asmarvelous refrigerating plants reduced the temperature of the whole city to a comfortable maximum, forthese were only a few of the suggestions of the limitless possibilities of the latest Tesla discovery."Just what is your new invention?" I asked. "I have accomplished what mechanical engineers have beendreaming about ever since the invention of steam power," replied Dr. Tesla. "That is the perfect rotaryengine. It happens that I have also produced an engine which will give at least twenty-five times as muchpower to a pound of weight as the lightest weight engine of any kind that has yet been produced. "In doingthis I have made use of two properties which have always been known to be possessed by all fluids, butwhich have not heretofore been utilized. These properties are adhesion and viscosity.http://www.frank.germano.com/teslaturbine.htm (10 of 15)2004/11/22 09:47:13 AMTesla's Turbine: The Tesla, Bladeless Boundary Disk Turbine"Put a drop of water on a metal plate. The drop will roll off, but a certain amount of the water will remain onthe plate until it evaporates or is removed by some absorptive means. The metal does not absorb any of thewater, but the water adheres to it. "The drop of water may change its shape, but until its particles areseparated by some external power it remains intact. This tendency of all fluids to resist molecular separationis viscosity. It is especially noticeable in the heavier oils. "It is these properties of adhesion and viscosity thatcause the 'skin friction' that impedes a ship in its progress through the water or an airplane in going throughthe air. All fluids have these qualities--and you must keep in mind that air is a fluid, all gases are fluids, steamis fluid. Every known means of transmitting or developing mechanical power is through a fluid medium."Now, suppose we make this metal plate that I have spoken of circular in shape and mount it at its center ona shaft so that it can be revolved. Apply power to rotate the shaft and what happens? Why, whatever fluid thedisk happens to be revolving in is agitated and dragged along in the direction of rotation, because the fluidtends to adhere to the disk and the viscosity causes the motion given to the adhering particles of the fluid tobe transmitted to the whole mass. Here, I can show you better than tell you." Dr. Tesla led the way into anadjoining room.On a desk was a small electric motor and mounted on the shaft were half a dozen flat disks, separated byperhaps a sixteenth of an inch from one another, each disk being less than that in thickness. He turned aswitch and the motor began to buzz. A wave of cool air was immediately felt. "There we have a disk, orrather a series of disks, revolving in a fluid--the air," said the inventor. "You need no proof to tell you that theair is being agitated and propelled violently. If you will hold your hand over the center of these disks--you seethe centers have been cut away--you will feel the suction as air is drawn in to be expelled from theperipheries of the disks. "Now, suppose these revolving disks were enclosed in an air tight case, soconstructed that the air could enter only at one point and be expelled only at another--what would we have?""You'd have an air pump," I suggested. "Exactly--an air pump or blower," said Dr. Tesla. "There is one now inoperation delivering ten thousand cubic feet of air a minute. "Now, come over here."He stepped across the hall and into another room, where three or four draughts men were at work andvarious mechanical and electrical contrivances were scattered about. At one side of the room was whatappeared to be a zinc or aluminum tank, divided into two sections, one above the other, while a pipe that ranalong the wall above the upper division of the tank was connected with a little aluminum case about the sizeand shape of a small alarm clock. A tiny electric motor was attached to a shaft that protruded from one sideof the aluminum case. The lower division of the tank was filled with water. "Inside of this aluminum case areseveral disks mounted on a shaft and immersed in a fluid, water," said Dr. Tesla. "From this lower tank the
water has free access to the case enclosing the disks. This pipe leads from the periphery of the case. I turn
the current on, the motor turns the disks and as I open this valve in the pipe the water flows."
He turned the valve and the water certainly did flow. Instantly a stream that would have filled a barrel in a
very few minutes began to run out of the pipe into the upper part of the tank and thence into the lower tank.
"This is only a toy," said Dr. Tesla. "There are only half a dozen disks--'runners,' I call them--each less than
three inches in diameter, inside of that case. They are just like the disks you saw on the first motor--no
vanes, blades or attachments of any kind. Just perfectly smooth, flat disks revolving in their own planes and
pumping water because of the viscosity and adhesion of the fluid. One such pump now in operation, with
eight disks, eighteen inches in diameter, pumps four thousand gallons a minute to a height of 360 feet." We
went back into the big, well lighted office. I was beginning to grasp the new Tesla principle...
