This is the long await metal Tesla turbine. It has a number of design improvements
over the Tesla original turbine design. It has a new directional "injection" system that
delivers air straight between the disks, improving performance and allowing the turbine
to be reversed using a screwdriver while the turbine is running. The brass injector can
also be replaced and improved. A "blank" injector (no machined holes) is supplied with the
turbine for experimentation. There are 10 disks in total on a stainless steel axle/spindle.
The disks can be reconfigured in different ways, for example a new design of disks could
be made and easily substituted. The disk gaps and number of disks could even be changed
providing new washers were made/sourced. The turbine has a standard a 1/4" BSP threaded
connector for both the inlet and outlet pipes. An 1/4" BSP to Uni adapter is provided to allow
easy connection to an air compressor (8+ CFM recommended). The turbine comes with a 3
phase generator and 3 x 20 watt bulbs, easily generating 60 watts (generator can produce
more). The turbine design and generator mount allows for possibility of changing the
generator or connecting to something else. The turbine is supplied on a wooden base for
display and demonstration purposes (connected using 2x5mm Hex screws).
Tesla turbines are also known as cohesion turbines, bladeless turbines,
boundary layer tubines and Prandtl turbines.
