Method of increasing the service life of aircraft carbon disk brakes
First Claim
1. A method of increasing the service life of carbon disks which form the functional braking elements of a brake disk stack of an aircraft brake assembly, each brake assembly associated with a respective wheel of a plurality of wheels which comprise a landing gear configuration of the aircraft, the method comprising the steps of:
- establishing a preselected first group of brake assemblies of a total number of brake assemblies which are actuated for both low-pressure and high-pressure braking of the aircraft;
establishing a preselected second group of brake assemblies which comprises the remaining number of the total number of brake assemblies which are actuated only during high-pressure braking of the aircraft;
actuating the first group of brake assemblies during the taxi-snub stops of the aircraft when it is on the ground; and
actuating the first and second groups of brake assemblies during landing of the aircraft.

Abstract
The invention is directed to a method of increasing and/or extending the operational service life of an aircraft brake disk stack by selectively limiting the number of brake assemblies which comprise the aircraft landing gear configuration and which are put into operation during the time the aircraft is on the ground and subject to taxi-snub braking cycles while also providing that all of the brake assemblies of the total available on the aircraft are operational during landing of the aircraft.

3. A method of increasing the service life of carbon disks which form the functional braking elements of a brake disk stack of an aircraft brake assembly, each brake assembly associated with a respective wheel PG,12 of a plurality of wheels comprising a landing gear configuration of the aircraft, the method comprising the steps of:
-
providing a programmable brake controller which operates in conjunction with a pilot'"'"'s control for braking of the aircraft; installing switch means within the circuitry of each brake assembly, the switch means being interconnected through the brake controller to actuate each of said respective brake assemblies; and programming the brake controller to select various of the brake assemblies for braking action in accordance with a particular sequence such that all of the brake assemblies are actuated during an aircraft landing operation and only a preselected group of the total of brake assemblies is actuated during taxi braking operations of the aircraft when it is on the ground. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11)
