Instructables

Build a 15,000 rpm Tesla Turbine using hard drive platters

Step 7: Make the side panels (stators)

The side panels are 4.75" x 4.75" x 0.47" acrylic with untaped .25" holes to screw to the main chamber. The center hole is 0.6" and the counterbore is 0.28" deep.

The two 0.6" holes (one on each side) are the ONLY exhaust ports. The air spirals inwards across the face of the platters, through the ventilation ports, around the air spaces in the bearings (2nd picture), and finally out through these two holes.

However, more exhaust holes in the side panels might improve efficiency.

hi you mean to say the air is flowing out through the ballbearing? Thanks for an answer.
