Abstract

The invention discloses a linear electromagnetic arresting device for aircraft carrier landing or aircraft landing and relates to the technical field of electromagnetic arresting. The problems that an existing landing assisting and arresting system is large in mass and size, complex in structure and low in reliability, and a completely passive electromagnetic damping scheme cannot achieve arresting cable recovering and restoration are solved. The linear electromagnetic arresting device for aircraft carrier landing or aircraft landing is composed of two linear electromagnetic arresters and a arresting cable; the structures of the two linear electromagnetic arresters are the same, the linear electromagnetic arresters are symmetrically distributed with a landing runway as a center; and the two ends of the arresting cable are connected with secondary parts of the two linear electromagnetic arresters. According to the linear electromagnetic arresting device for aircraft carrier landing or aircraft landing, a linear motor and a linear electromagnetic damper are subjected to structural integration; the advantages that the structure is simple, the arresting force is controllable, and the arresting cable can be restored quickly are achieved; and the linear electromagnetic arresting device is suitable of carrier landing or landing of a carrier aircraft.

Description

Technical field [0001] The invention belongs to the technical field of electromagnetic arrest, and particularly relates to a linear electromagnetic arrest device for aircraft landing or landing. Background technique [0002] At present, the carrier-based aircraft's landing aid arresting system mainly uses arresting cables. Due to the very high flight speed, when the carrier-based aircraft is landing, the length of the aircraft carrier’s deck is far from sufficient for the landing and sliding distance, so it must be landed smoothly with the help of the resistance of the arresting cable. [0003] The traditional arresting cable system uses a hydraulic arresting device, which has disadvantages such as many moving parts, heavy system weight, large instantaneous impact force, and low reliability. In addition, in order to avoid that the arresting load during landing exceeds the strength of the airframe or the braking force of the hydraulic arresting device, the hydraulic arresting devic...
