Abstract

Brake wear sensors for the brake disc stacks commonly used in aircraft brake systems are disclosed. An ultrasonic transducer is employed to transmit signals to a reflective surface and to receive the reflected signals in return. The time that elapses between the transmission of the ultrasonic signal and the reception of its reflection correlates with the separation between the transducer and the reflective surface. The reflective surface is operatively connected to a pressure plate of the associated brake disc stack such that, as the stack wears, the reflective surface is displaced along with the pressure plate. That displacement correlates with brake wear. In one embodiment, the ultrasonic brake wear detector is an independent unit mounted to the brake housing, while another embodiment includes the detector as an integral portion of a brake actuator connected to such housing. A third embodiment for use with brake disc stacks exhibiting substantial wear before requiring service employs either twin cylinders, one with a piston and the other a wear pin, or a single cylinder housing a wear pin operatively fixed to the brake disc stack.

Abstract

A method for characterizing the health of a rechargeable battery includes measuring initial condition parameters of a rechargeable battery prior to the battery being placed into service. A baseline normalization of the initial condition parameters is performed using a standardized relationship data set for a norm battery to generate baseline normalization coefficients to normalize the initial condition parameters to the norm battery. Run-time condition parameters of the battery are measured after the battery is in service as part of a continuous built in test system. The run-time condition parameters are normalized using the standardized relationship data set for the norm battery and the baseline normalization coefficients to generate normalized run-time condition parameters for the battery. The normalized run-time condition parameters are then compared to the standardized relationship data set for the norm battery to calculate a state-of-charge and state-of-health for the battery as the run-time condition.

Abstract

Upgrading existing aircraft braking systems to accommodate replacement of existing brake units employing sintered friction materials with brake units employing carbon-carbon composite friction materials is often desirable. However, when upgrading the braking systems it is necessary to ensure that the integrity of the existing airframe is not compromised by the use of the new brake assemblies employing the carbon-carbon composite friction materials. Consequently, the present invention replaces existing pressure control valves of existing braking systems with an electronic control unit (126) coupled to a pressure control servovalve (128), thereby ensuring proper application of hydraulic pressure to brake assemblies (122). An advantage of this invention is that the pressure profile of the hydraulic fluid is controllable and hence the integrity of the airframe is maintained.

The system may include an audio detection circuit to monitor the sound generated by the firearm and transmit a signal to a flash controller to cause the light source to illuminate. The screen will then re-seal around the hole so that the light no longer traverses the screen.

Abstract

A brake apparatus (1 ) and method of operating the apparatus are disclosed. The apparatus (1 ) has a plurality of brake elements (2, 3, 4, 5, 6) with a combined thickness of Y. At least one of the brake elements (2, 3, 4, 5, 6) has a wear portion (22a, 22b) for tribological interaction with a wear portion (52b, 62a) of an adjacent element (5, 6) and is formed in two separable parts (21a, 21 b) having thicknesses A1 and A2. The method includes operating an actuator (8) at an actuation extension length less than a maximum actuation extension length to cause the wear portions (22a, 22b, 52b, 62a) of the brake elements (2, 5, 6) to tribologically engage and thereby wear. This tribological engagement is such that as the elements (2, 5, 6) wear to a combined thickness of less than Y the extension length of the actuator is increased. A spacer (23) is inserted between the two parts (21 a, 21 b) of the brake element (2) to cause the wear portions (22a, 22b, 52b, 62a) to be tribologically engagable at a actuation extension length less than the increased actuation extension length.

Abstract

A braking system (1) for an aircraft which includes a by-pass control system (9) for activation when undemanded braking or loss of braking is detected. The braking system (1) comprises: a brake pedal transducer (2) for generating a brake pedal actuation signal when a brake pedal (3) is applied; brake actuation means (5) for activating a brake (6) on receipt of a braking signal; braking pressure transducer means (7) for generating a braking output signal related to the braking force applied to the brake (6); primary processing means (4) in electrical communication with the brake pedal transducer (2) and the brake actuation means (5) and adapted to generate a braking signal on receipt of a brake pedal actuation signal; secondary processing means (8) adapted to receive the brake pedal actuation signal and braking output signal; and a bypass braking control system (9) adapted to receive the brake pedal actuation signal from the brake pedal transducer (2) and generate a braking signal in response to the brake pedal actuation signal. The secondary processing means (8) is adapted to disable the primary processing means (4) and enable the bypass braking control system (9) on detection of undemanded braking or loss of braking from the brake pedal actuation signal and braking output signal.

Abstract

A mechanical-to-electrical sensing structure has first and second movable blocks formed in a handle layer. A first hinge is coupled to the first and second movable blocks and configured to resist loads other than flexing of the first hinge. A first gauge is separated from the first hinge and aligned to provide that a moment tending to rotate one of the first or second blocks relative to the other about the first hinge and applies a tensile or compressive force along a length of the first gauge. The first gauge is formed from a device layer with an oxide between the device and handle layers, and the sensing structure is made from an SOI wafer.
