Abstract

A worldwide new high temperaturebearing has been developed, manufactured and successfully tested. Loads being equivalent to more than 4 complete reentries from space have been simulated in a special test facility. The bearing always operated reliable during testing. Such new bearings have revolutionized hot control surface design especially with respect to temperature resistance and lightweight design. They will be installed into the body flaps developed and manufactured by MAN Technologie for the X-38 re-entry space vehicle 201 of NASA. Because of the high temperature resistance of such bearings, re-entry temperature profiles are less constrained by control surface temperature limits compared with metallic based control surfaces.
