Brake characteristics

机译:刹车特性

摘要

A method and apparatus for determining whether an aircraft wheel brake is capable of performing a future rejected take-off event (RTO). The method includes determining whether a predicted mass of the brake is sufficient to abort take-off 410, this calculation being based on a rejected take-off energy parameter, which may be input by a user, and brake parameters, which may include an upper temperature limit 408. The RTO energy parameter may be based on decision speed V1 and aircraft weight 404, and whether the mass is sufficient may be determined by comparing it to a mass limit 406, 410 defining the minimum mass to perform RTO. The predicted brake mass may be calculated based on brake wear due to aircraft braking events and brake oxidation of the carbon-carbon (C-C) brake discs. The life of the brake (e.g. number of predicted future use cycles until mass insufficient) may be determined 412, and notifications may be issued 414, (420; fig. 4b) to warn the pilot that servicing, maintenance or replacement is required.
