Abstract: A brake component indicator configured to provide a visual indication of the release state of the brake component; the indicator comprising an indicator element connected to the brake component and moveable with the component during a braking operation, whereby the indicator element is provided with means to provide a visual indication of the direction and/or the distance moved by the indicator element during the braking operation. Preferably, the indicator element is in the form of a rod connected to a brake disk or pad that engages a moving part in a braking operation to brake the moving part, the rod provided with indicator means whose position is an indication of the distance the brake disk or pad has traveled to engage the moving part.

Abstract: A brake unit comprises said rotor disc rotatable about a central axis of rotation and a first brake pad mounting element having a first end and a second end and a longitudinal outer, side, surface extending there between, wherein a first brake pad is provided at said first end of said first brake pad mounting element and positioned facing a first face of said rotor disc. The first brake pad mounting element comprises a first locking feature provided on its outer, side, surface. The brake unit further comprises first locking element that pivots about pivot and that is movable about said pivot axis so that a locking feature of said locking element can come into contact with, or be moved away from said outer, side, surface of said first brake pad mounting element.

Abstract: There is provided an apparatus for applying a braking force to a brake disc using a brake pad. The apparatus comprises a lever configured to rotate about a first fulcrum, and a pressing member attached to said lever and for urging a brake pad against a brake disc. A component is arranged and configured to ensure that said pressing member has a circular translational movement upon rotation of said lever, and a rotatable input member is configured to rotate a first member. In use, rotation of said first member causes movement of an actuating member along an first axis (A), and said axial movement of said actuating member causes said lever to rotate about said first fulcrum for applying a braking force to said brake disc.

Abstract: A brake disk defines an annular shape having a radially inner side and a radially outer side. The brake disk includes: a radially outer braking surface, the braking surface having a maximum operating temperature; a fusible material section radially inward from and connected to the braking surface. The fusible material has a maximum operating temperature, the fusible material section suitable for transmitting torque between the braking surface and a shaft. The maximum operating temperature of the braking surface is higher than the maximum operating temperature of the fusible material section. When the temperature of the fusible material section raises above the maximum operating temperature of the fusible material section, the fusible material section is configured to no longer transmit torque between the braking surface and the shaft.

Abstract: A device and a control method are described for a swinging aircraft door (3), mobile around a swinging axis (21) substantially parallel to the longitudinal axis of the aircraft via a motorized mechanism and having integrated boarding stairs (31). The method includes the capture of electromagnetic or ultrasonic radiation using at least one sensor (401, 501); the detection of something on the stairs on the basis of captured electromagnetic or ultrasonic radiation, in order to deduce therefrom whether a detection condition is satisfied or not; and, driving of the motorized mechanism in order to control the closure of the door in response to a closure command except in case of detection of something on the stairway.
