Abstract
A metallic aircraft brake disk having thermal relief slots therein is provided. The brake disk is of an annular shape with force bearing slots in one of the circumferential surfaces thereof to engage the disk with a portion of the aircraft. A plurality of thermal relief slots extend from an opposite circumferential surface of the annular brake disk. The thermal relief slots are in the shape of a dual armed hook anchors and are configured to minimize the amount of material removed to form each slot, while maximizing certain radii of the slot head. Particularly, an elongated radial slot terminates in a slot head, the slot head being formed of a number of interconnected curvate surfaces. The radii of the curvate surface opposite the end of the radial slot is maximized.
Claims10
A metallic aircraft brake, comprising:
- an annular disk having concentric inner and outer circumferential surfaces;
- a plurality of force bearing slots in one of said circumferential surfaces for engaging said disk with a portion of an aircraft;
- and
- a plurality of thermal relief slots extending from one of said circumferential surfaces, said thermal relief slots being anchor shaped for minimizing stress thereat.
