Abstract: A testing apparatus includes a chamber, having an interior maintained at a predetermined pressure, a rotor rotatably disposed within the interior of the chamber, and a sensor disposed within the interior of the chamber. When the rotor rotates, the at least one sensor measures a testing characteristic of an object disposed within the interior of the chamber as the object interacts with the rotating rotor. A method includes setting a predetermined pressure of a chamber, rotating a rotor, and maintaining a gap between a surface of an object to be tested and a surface of the rotor by adjusting, with an actuator, the object to be tested or the rotor based upon a change, as measured by a laser, in the dimension of the object to be tested or the rotor.
