Spherical air bearing systems are commonly used to test the attitude control systems of small satellites. The frictionless nature of the spherical air bearing makes it easy to simulate a zero-gravity environment, allowing the satellite’s pitch, roll, and yaw control systems to function as they would in space without cumbersome and expensive test simulations.
Aircraft manufacturing has changed significantly in recent years. Instead of being assembled in one spot, most aircraft today are built on moving assembly lines similar to those used by automakers. Despite this evolution, however, many aerospace manufacturers still rely on hydraulic jacks, tuggers or overhead cranes to move aircraft through the various manufacturing stages.
