2314 results about "Arresting gear" patented technology

An arresting gear, or arrestor gear, is a mechanical system used to rapidly decelerate an aircraft as it lands. Arresting gear on aircraft carriers is an essential component of naval aviation, and it is most commonly used on CATOBAR and STOBAR aircraft carriers. Similar systems are also found at land-based airfields for expeditionary or emergency use. Typical systems consist of several steel wire ropes laid across the aircraft landing area, designed to be caught by an aircraft's tailhook. During a normal arrestment, the tailhook engages the wire and the aircraft's kinetic energy is transferred to hydraulic damping systems attached below the carrier deck. There are other related systems which use nets to catch aircraft wings or landing gear. These barricade and barrier systems are only used for emergency arrestments for aircraft without operable tailhooks.

Electromechanical vehicle brake

A combined electromechanical vehicle brake has a hydraulically activated operating brake and an electromechanically activated parking brake apparatus. A hydraulic operating pressure chamber in a brake housing is delimited by a brake piston that can be loaded by hydraulic pressure to carry out operating braking actions. The brake piston can be activated along a longitudinal piston axis to achieve a braking effect. The parking brake apparatus acts upon the brake piston by a gear unit because the gear unit converts the rotational movement of an electromechanical actuator into a translational movement, causing the brake piston to be activated to carry out parking brake processes and remain in the activated position. The gear unit has a threaded spindle and a threaded nut that contact one another via a plurality of rolling elements. A spring element allows the rolling elements to slip when the gear unit is activated in the unloaded state.
