Previous NASA Administrator Dan Goldin watches a demonstration of Oil-Free Technology at 2001 Air Venture
|
Visit the NASA Oil-Free Turbomachinery display and meet the Oil-Free staff members at AirVenture. We're located in the NASA General Aviation building across from the main NASA display building, north of the tower.

| What happens when a foil bearing is given a shock load? This demonstration rig has a foil bearing supported rotor under operation that can be given shock loads up to 20g's. An oscilloscope connected to rotor shaft displacement probes shows the real-time motion of the shaft due to a shock load. |
Oil-Free Shock Tolerance Demonstration Rig
Drawing of Shock Tolerance Demonstration Rig
This demonstration rig will let you feel the operation of a foil bearing from standstill to liftoff to coast down. The bearing is mounted on a rotor with a torque rod sticking out of the top of the display box. On startup you can feel the torque spike as the bearing starts to float and on shutdown when it again makes rubbing contact. While running you can feel how little friction exists.
Hydrodynamic Bearing Demonstration Rig |
This demonstration consists of a hand-cranked see-through acrylic bearing with water flow representing air. As the journal rotates, a fluid film is formed between the sliding surfaces. The faster the journal rotates, the more load can be supported when you or a colleague press down on the torque arm at the top of the display cabinet. |
| The objective of this technology is to apply recent advances in foil bearings, solid lubricant coatings and analytical modeling to design, fabricate and test an Oil-Free heavy-duty class diesel engine turbocharger (more...) |
