A vehicle includes a vehicle body with a first body end configured to face an incident ambient airflow and an underbody section. The vehicle also includes a brake subassembly arranged proximate the underbody section and configured to decelerate the vehicle. An airflow regulation system includes a deflector moveably mounted to the underbody section and configured to regulate an underbody portion of the incident airflow to the brake subassembly. The system also includes a mechanism configured to change a position of the deflector to selectively direct the underbody portion of the incident ambient airflow to the brake subassembly and enhance aerodynamics of the vehicle body. The system additionally includes a first sensor configured to detect a predetermined operating condition of the brake subassembly. Furthermore, the system includes a controller configured to regulate the mechanism for selecting the deflector's position in response to the detected predetermined operating condition of the brake subassembly.

A brake disk includes a first abrasive disk, a second abrasive disk and a heat dissipation disk co-axially sandwiched between the first abrasive disk and the second abrasive disk. A middle disk is co-axially mounted onto the first abrasive disk and the second abrasive disk, wherein the middle disk is adapted to be mounted to a hub. A specific heat capacity coefficient of the heat dissipation disk is greater than that of the first abrasive disk and the second abrasive disk for absorbing thermal energy from the first abrasive disk and the second abrasive disk and lowering the temperature of the first abrasive disk and the second abrasive disk during braking.

An aircraft wheel (1) comprising a hub connected to a rim (3) provided with a tire (100), the hub having an outer surface that extends facing an inner surface (4) of the rim (3) and that co-operates therewith to define an annular space for receiving a stack of brake disks including rotor disks having axial peripheral notches, each notch receiving a segment of an axial bar (10) extending projecting from the inner surface (4) of the rim (3), and respective heat shields (20), each in the form of an annular segment, being mounted between the two bars (10) of respective pairs of adjacent bars. Each heat shield (20) includes at least one holder portion bearing against at least one first abutment (19, 119) secured to the rim (3) in order to hold the heat shield (20) in position on the rim (3) elastically.

A system and method are provided for continuous monitoring and controlling of aircraft braking that can reduce brake wear and aircraft operating costs through the retention of carbon brake powder from the brakes or addition of carbon powder in a device mounted with respect to the brake disc stack. The use of carbon powder reduces brake wear by providing small particles between the brake discs, acting as a buffer between the brake discs when the brake stack is clamped together. Moreover, when carbon powder or small particles are used at application, such use reduces the roughness of the carbon surface and reduces the number of large particles from braking off the carbon surface, thereby reducing brake wear. Adaptive or selective braking may be used in conjunction with carbon powder to further reduce carbon brake wear.

A vehicle includes an underbody opening to a wheel well, a wheel accommodated in the wheel well, a brake inside the wheel and an air spat at the underbody. The air spat has an upright Coanda surface open to free oncoming underbody airflow. The Coanda surface includes a trailing section aimed inside the wheel and at the brake.

An internally ventilated brake disc with a disc coning reducing arrangement is provided in which temperature differences between inboard and outboard sides of the brake disc are minimized in order to reduce coning-causing differential thermal expansion. Between a radially inner region of a brake disc that includes brake disc-to-axle hub mounting features and a radially outer region the mass of the inboard side of the brake disc is distributed in a manner that reduces the amount of differential thermal expansion occurring during brake application between the inboard and outboard sides of the brake disc, thereby minimizing thermally-induced coning effects. The inboard side disc plate portion may having an increasing axial thickness in the direction from the radially outer region to the radially inner region, providing additional material mass to receive and dissipate heat energy received during a braking event.

A cooling system for a vehicle may include at least two air ducts formed at both side of an exterior air intake port; a low temperature radiator to release heat of coolant into the air; a high temperature radiator to release heat of coolant into the air; an ancillary low temperature radiator to release heat of coolant into the air; an ancillary high temperature radiator disposed inside of another one of the at least two air duct to release heat of coolant into the air; a turbocharger; an intercooler cooling compressed air generated from the turbocharger by using coolant flowed via the low temperature radiator and the high temperature radiator; a compressor; a condenser cooling the compressed refrigerant generated from the compressor by using coolant flowed via the low temperature radiator; a high temperature coolant passage; and a low temperature coolant passage.
