Tesla Turbine Or The Boundary Layer Turbine
Tesla’s Airship -Nikola Tesla believed he would be the first man to fly. -His Idea was “a flying machine propelled by an electric motor, with power supplied from stations on the earth. - In 1913 he received the patent for what he called “the perfect rotary engine”.
-High-pressure fluid enters. -Fluid exits through the exhaust ports in the center. - A boundary layer formed between the surface of the disk and the fluid (water, oil, air) causes a centripetal motion forcing everything to the center. -Small but powerful engine that has only one moving part. -You can run the turbine in a reverse direction flow so you can use it as a pump. - No blades or tight orifices, you can pump dirty fluid or a fluid that has sediment in it without harming the pump.
The Basic Parts The Disks- The only moving part in the turbine. -Early disks made of inferior materials. -Modern day made of carbon-fiber, titaniumimpregnated plastic or Kevlar-reinforced disks. - They spin at 3, 600 – 85, 000 rpm. - If disk failure occurs.
Disks More disks = more surface area. - More surface area= more power -
Stator Simple, lightweight. Can be aluminum, steel, plastic, composite. -Cylindrical design, Bladeless. - Houses the bearings. - Does not require crankcase oil = lighter weight. - Two ports for clockwise/countercloc kwise movement. -
Efficiency • First built in 1906, Had 8, 6” disks. • Weighed less than 10 pounds and developed 30 Hp. • The rotor attained such high speeds, 35, 000 rpm, that the metal disks stretched. • In 1910 they built a larger model with 8, 12” disks. • At 10, 000 rpm developed 100 horsepower. • Lastly they built one with 15, 60”. • Operating at 3, 600 rpm, generates 675 Hp. Disks always distorted. • Tesla claimed 95% efficiency, but could only obtain 60% • Modern day engines are around 27 -28%
• In the late 1970’s Warren Rice at Arizona State University, created a version of the Tesla turbine that operated at 41%. • As of 2007, Frank Germano has one in continuous operation without component failure for 7 years. • He has achieved 42. 2% efficiency at 13, 000 rpm, with 14. 8 horse power output.
Modern Day Usage This is the Phoenix Navigation and Guidance Inc. turbine.
-COMBINED THE DISK TURBINE WITH A PULSE DETONATION. -THEY CLAIM DELIVERS UNPRECEDENTED EFFICIENCIES. -THERE ARE 29 ACTIVE DISKS, EACH 10 INCHES IN DIAMETER. -THE ENGINE GENERATES 18, 000 RPM AND 130 HORSEPOWER. - THEY USE CARBON-FIBER, TITANIUMIMPREGNATED PLASTIC AND KEVLAR-REINFORCED DISKS.
