Appeal No. 2005-2698 Παγε 2
Application No. 10/316,636
BACKGROUND
The appellants' invention relates to a multi-disc carbon brake system and method
for use in an aircraft landing system. In accordance with appellants' invention, rotors
and stators of different thicknesses are used. A first group of rotors and a first group of
stators are placed in alternating relation between a first pressure plate and a first back
plate, with the thickness of the rotors being greater than that of the stators (Figure 1).
When the wear stroke of the piston is reached because of wear and thinning of the
stators and rotors (Figure 2), a first spacer is inserted to reset the wear stroke (Figure
3). When the wear stroke is again reached because of further wear on the stators and
rotors (Figure 4), the stators are replaced with stators having a thickness greater than
the first group of stators (Figure 5). In this configuration, the thickness of the stators is
thus greater than that of the rotors, which have been partially worn. When the wear
stroke is again reached (Figure 6), a second spacer is inserted to reset the wear stroke
(Figure 7). Subsequently, when the wear stroke is again reached after additional
braking cycles and further wear of the rotors and stators (Figure 8), the now fully worn
rotors are replaced with new rotors having the same thickness as the first group of
rotors (Figure 1). A copy of the claims under appeal is set forth in the appendix to the
appellants' brief.
