Patent number: 8041490Abstract: The system and method for monitoring wear of one or more aircraft parts, such as an aircraft brake, an aircraft tire, a standby system, and landing gear. One or more sensors are provided for sensing a parameter of usage, and an estimate of usage of the part can be determined based upon the signal indicating the sensed value of the parameter of usage of the aircraft part. A plurality of sensors can be provided for sensing usage of a plurality of parts of the aircraft, and the estimate of usage of the part can be stored for access of the estimate by ground personnel. As applied to monitoring wear of an aircraft brake, a linear brake wear indicator attached to the brake moves a discrete distance when the brake is actuated, and a linear position encoder measures the distance traveled by the linear brake wear indicator as an indication of brake usage.Type: GrantFiled: June 3, 2010Date of Patent: October 18, 2011Assignee: Hydro-Aire, Inc.Inventor: Garrett H.

Publication number: 20110226569Abstract: A brake system control unit controls one of first and second portions of a wheel brakes electric brake actuators to activate one of the first and second portions of the actuators and deactivate the other during an inhibited braking mode. The control unit controls the activated portion of the brake actuators to generate a braking force greater than the commanded braking force of the brake pedal command, such as twice the commanded braking force, to compensate for the deactivated portion of the brake actuators. The inhibited braking mode is discontinued during emergency braking when the commanded braking force is greater than or equal to a predetermined braking force. The inhibited braking mode is also discontinued when failure of one or more brake actuators is detected.Type: ApplicationFiled: March 19, 2010Publication date: September 22, 2011Applicant: HYDRO-AIRE, INC.Inventor: GARRETT H.

Patent number: 7991531Abstract: A wheel speed transducer including a magnetic device associated with a wheel and a sensor device associated with the axle of the wheel provides data indicative of the velocity of the wheel. A processor located at the axle receives the wheel speed data and processes it to perform antiskid control functions. The velocity data is stored in a data concentrator also associated with the axle. A tire pressure sensor, a brake temperature sensor and a brake torque sensor, each associated with the wheel, send data to the processor at the axle, for storage in the data concentrator. A transmitting antenna associated with the axle and in communication with the data concentrator transmits stored data to a receiving antenna associated with the wheel.

Patent number: 7837279Abstract: The adaptive brake application and initial skid detection system allows rapid brake application and prevents deep initial skids. Brake torque is compared with a predetermined threshold brake torque. Wheel velocity error signals are also generated to indicated the difference between the wheel velocity and a reference velocity signal. A torque bias modulator integrator responsive to brake torque signals adjusts the wheel velocity error signals to provide an anti-skid control signal. The torque bias modulator integrator can also be initialized to the value of the measured brake torque when the wheel velocity error signals indicate the beginning of a skid. Brake torque difference signals are generated to indicate the difference between brake torque and a commanded brake torque, and an adjusted brake torque error signal is generated in response to the brake torque difference signals.Type: GrantFiled: January 8, 2009Date of Patent: November 23, 2010Assignee: Hydro-Aire, Inc.Inventors: Bijan Salamat, Robert D.

Publication number: 20100222942Abstract: A taxi brake inhibit system overcomes problems of discontinuities in pedal “feel” that can occur by use of a taxi brake inhibit system, by adding a new pedal “feel” logic in which twice the brake force is commanded for a given brake pedal application when taxi brake inhibit is active. The taxi brake inhibit system relies upon two different brake force vs. brake pedal application curves to compensate for the difference in deceleration that is achieved for a given brake pedal application depending upon whether the taxi brake inhibit is active or inactive. Such system effectively eliminates undesirable deceleration bumps, yaw effects and changes in pedal feel during braking. The taxi brake inhibit feature is also shut off to both fore-aft brake pairs if any non-normal taxi brake inhibit condition exists on either fore-aft brake pair.Type: ApplicationFiled: January 27, 2010Publication date: September 2, 2010Applicant: HYDRO-AIRE, INC.Inventors: GARRETT H.
