精品文档---下载后可任意编辑特斯拉无叶涡轮泵制作方法Building a Tesla Turbine from hard drive platters Please note that I am not a Physicist or a machinist (yet). I have been interested in Nikola Tesla for some time, and I was looking for a project to gain some experience in the machine shop. My job is to provide Lecture Demonstrations, so my goal was to produce a teaching tool rather than an efficient engine. For background material, Wikipedia has several good review articles about Nikola Tesla, the Tesla Turbine, the Boundary Layer Effect, and Reynolds Number. 1精品文档---下载后可任意编辑DisksAt first I tried using CDs because of their large surface areas, but they didn't hold up too well under the milling machine. I also had a stack of platters from old and defective hard drives, but I didn't know if the smaller diameter disks would work as well. One problem I ran into is that some newer hard drives use ceramic disks instead of metal. They're still coated with metal, but they're thinner and a couple platters shattered when I tried to machine them: My original plan for the center hole pattern had small holes (for threaded rods and washers for spacers), as well as large holes (for air vents). 2精品文档---下载后可任意编辑The second set of platters had radial arcs cut in them such that the inside edge of the radial cutout is close to the outside diameter of the spacers that I removed from the hard drive assemblies. The hard drive platters were stacked and clamped to a rotary table between two sheets of scrap aluminium but the top disk (above picture) still took some extra damage. The rest of the platters look much better though (see the complete rotor assembly below). SpacersI decided to ...
