  • Publication number: 20240140596
    Abstract: An aircraft brake control system for controlling antiskid braking of an aircraft wheel is disclosed including a control assembly having a mode controller which sets the mode of operation of an antiskid brake calculator, configured to set a first mode, when an input of the indication of a brake energy supply configuration indicates a first brake energy supply being used, in which the antiskid brake calculator applies a first restriction level on a rise rate of the antiskid brake command, and a second mode, when the input 305 indicates a second brake energy supply being used, in which the antiskid brake calculator applies a second, lower, restriction level on a rise rate of the antiskid brake command.

  • Patent number: 11867206
    Abstract: A method of removing hydraulic fluid from an aircraft hydraulic system is disclosed including a hydraulically actuated mechanism that is actuated by an electrohydraulic servo valve, a hydraulic fluid port through which hydraulic fluid can escape, and a hydraulic fuse with a closed state and an open state between the electrohydraulic servo valve and the hydraulic fluid port. The hydraulic fluid port is opened, and then the activation of the electrohydraulic servo valve is controlled to force hydraulic fluid to escape from the hydraulic system via the hydraulic fluid port, the control being so that the hydraulic fuse does not enter and remain in the closed state.

  • Publication number: 20230240474
    Abstract: A toasting tray for buns is shown and described. The toasting tray for buns comprises a ridge that is further comprised of an apex defined by the intersection of a first side surface and a second side surface. The toasting tray for buns also has a horizontal section connected at a lower end of said sides. A plurality of ribs protrudes above the apex, the first side surface, second side surface, and the horizontal section of the toasting tray for buns. Additionally, a plurality of elongated conducting elements are positioned inside of the ridge. The plurality of elongated conducting elements are in thermal contact with a downward facing surface of the toasting tray.

  • Publication number: 20230101767
    Abstract: An aircraft hydraulic braking system having at least one hydraulic accumulator and a brake actuator. The at least one hydraulic accumulator is the sole source of pressurised hydraulic fluid in the aircraft hydraulic braking system for operating the brake actuator and thereby apply a braking force to a wheel on an aircraft.

  • Publication number: 20220266992
    Abstract: An aircraft brake control system for controlling anti-skid braking of at least first and second wheels in a wheel set of an aircraft is disclosed. The system includes a control assembly having wheel speed inputs including an input of an indication of the wheel speed of the first wheel, and an input of an indication of the wheel speed of the second wheel, a wheel speed comparator for determining which of the wheel speeds indicated is a lowest wheel speed, and an output for indicating a wheel speed other than the lowest wheel speed. An aircraft landing gear, an aircraft, and methods of braking an aircraft are also disclosed.

  • Publication number: 20220017237
    Abstract: A method of testing an aircraft landing gear is disclosed including: a) generating a test signal with the first tachometer, wherein the first wheel is not rotating during the generation of the test signal; b) receiving the test signal via one of the tachometer output lines; c) issuing a braking command in response to the receipt of the test signal, wherein the braking command is issued via the braking command line which is associated with the one of the tachometer output lines; and d) monitoring a response of the first or second braking system to the braking command to test for a cross-connection between the first and second braking systems. The landing gear includes first and second wheels; a first braking system having a first tachometer mounted to the first wheel and configured to generate a first tachometer signal indicating rotation of the first wheel, and a first brake configured to brake the first wheel.
