A bidirectional windage resistance brake apparatus including a base, a first cylinder, a second cylinder, a first windage resistance plate and a second windage resistance plate, a tail of the first windage resistance plate is hinged with the base; the first windage resistance plate includes a first supporting rod, one end of which is hinged to a middle portion of the first windage resistance plate, and another end is connected with the first cylinder; a tail of the second windage resistance plate is hinged with the base; the second windage resistance plate includes a second supporting rod, one end of which is hinged to a middle portion of the second windage resistance plate, and another end is connected with the second cylinder. The brake apparatus is high in brake efficiency and reliability.

Braking systems for aircraft are disclosed. An example braking system includes a brake pad movably coupled to a lower section of a fuselage of the aircraft. The brake pad is movable between a stowed position and a deployed position. An actuator is configured to deploy the brake pad from the fuselage during an emergency braking event. The brake pad to engage a surface of a runway and increase frictional force to reduce a speed of the aircraft during the emergency braking event.

A rear suspension for a three-wheeled reverse trike includes a front lever arm pivotably affixed to a frame pivotable about a front lever arm pivot axis. A slider is translatably attached to the front lever arm. A first pushrod is pivotably connected at a first end to the slider and pivotably connected at a second end to at least one of a front upper or lower control arms for the front wheels. A rear lever arm is pivotably affixed to the frame and pivotable about a rear lever arm pivot axis, the rear lever arm extending to a rear lever arm distal end. A rod pivotably connects the front and lever arms. A first pivotable end of the rear upper control arm is pivotably connected to the rear lever arm distal end, and a second pivotable end of the rear upper control arm is pivotably connected to a rear spindle.

An electronic parachute deployment system includes an electronic actuator, a control module, a deployment actuator, and a release mechanism. A parachute is positioned on a payload device, such as a racecar, to slow or stop the payload upon receipt of an electronic deployment activation signal. The electronic deployment signal is verified, including determining proper voltage and source. The deployment system includes multiple redundancies including mechanical deployment redundancy, remote deployment redundancy, and power supply redundancy. The control module responsible for monitoring deployment includes indicators and sensors to indicate a status, operation, or mode relative to the operability of the payload device, relative to components of the release mechanism, and relative to the parachute deployment.

This disclosure relates to an electrified vehicle configured to address an excess braking request, such as a braking request in excess of what can be met by an energy recovery mechanism, by selectively increasing the drag of the electrified vehicle. A corresponding method is also disclosed. An example electrified vehicle includes an energy recovery mechanism, an actuator configured to adjust a position of a moveable component influencing a drag of the electrified vehicle, and a controller. The controller is configured to instruct the energy recovery mechanism to meet a braking request and, when the braking request cannot be met by the energy recovery mechanism, the controller is configured to instruct the actuator to adjust the position of the moveable component to increase the drag of the electrified vehicle.
