Disclosure of Invention

The invention provides a novel arresting device technology for landing sliding and running deceleration of a carrier-based aircraft, namely a pulley speed-changing nonlinear magnetic coupling arresting cable which is essentially an application of a disk/cylinder type magnetic retarding technology.

Drawings

Fig. 1 and 2 are schematic structural diagrams of a nonlinear magnetic coupling arrester wire, which is described in the invention 201911004353.8, wherein fig. 1 is a front view, and fig. 2 is a view along direction a-a. The nonlinear magnetic coupling blocking cable is an application of the disk/cylinder type magnetic retarding technology. When the airplane lands and runs, the tail hook hooks the arresting cable to pull the cable collector to move along the longitudinal sliding guide rail at a high speed, the cable collector pulls the transmission cable, so that the winding drum is driven to rotate, the winding drum is connected with the rotor of the magnetic retarder, the winding drum and the rotor of the magnetic retarder rotate together, the rotor of the magnetic retarder and the stator form magnetic coupling to convert kinetic energy into heat energy, and therefore the airplane running on the ground is braked at a slow speed.

The cable collector is embedded between two longitudinal sliding guide rails and needs to be provided with a certain balance weight. The reset damper is used for limiting the reset of the cable collector, a rubber pad can be used between the reset damper and the cable collector to reduce impact sound when the reset damper and the cable collector are contacted, and the rubber pad can be assembled on the reset damper and also can be assembled on the cable collector. The reset damper is relatively small in impact force possibly suffered by the cable collector during resetting, so that the damper can be in the form of a common conventional steel wire spring, an air spring or an oil-gas spring, and if the cable collector needs to reset at a high speed and a large impact force is possibly generated, a hydraulic buffer system consisting of a hydraulic cylinder, an energy accumulator, a flow control valve, a hydraulic pipeline and the like can be adopted. The cable collector resetting driving device can use an electric motor or a hydraulic motor, and the electric motor or the hydraulic motor drives the winding drum to rotate so as to drive the transmission cable to pull the cable collector to reset. The arresting damper may be subjected to a large impact force, and therefore it is preferable to use a hydraulic cushion system consisting of a hydraulic cylinder, an accumulator, a flow control valve, a hydraulic line, etc. so as to allow a slow braking of the landing and running aircraft without using a conventional damper in the form of a wire spring, an air spring, or a hydro-pneumatic spring, and if the landing and running distance of the aircraft can be effectively controlled so that the arresting damper is not subjected to a large impact, a spring type damper in the form of a conventional wire spring, an air spring, or a hydro-pneumatic spring, etc. may be used. The pulley is mainly provided for changing the spatial position and the guide of the cable, and attention is paid to the anti-drop design of the cable. The magnetic retarder preferably uses a very large load adjustable magnetic retarder which has a good clutch function, if the very large load adjustable magnetic retarder is to be used, a clutch can be additionally arranged between the very large load adjustable magnetic retarder and a winding drum, and the magnetic retarder preferably adopts a liquid cooling type because the kinetic energy is large when an airplane lands and runs, and the reliability of the magnetic retarder during continuous work is ensured by forced liquid cooling. The electric motor or hydraulic motor used by the cable collector resetting driving device is in an idle working state when the airplane lands and runs, and a clutch can be additionally arranged between the cable collector resetting driving device and the winding drum.

The landing and running time of the airplane is very short, so that the power transmission speed change system generally only adopts a speed increaser or a speed reducer as required, and can also adopt a speed changer to adapt to the landing and running speed reduction braking of different types of airplanes through gear change. According to the carrier-based model, the power transmission speed change system can be omitted by reasonably designing the diameter of the winding drum.
