Speed-reducing and stopping device for aircraft landing

Abstract

The invention provides a speed-reducing and stopping device for aircraft landing, and is particularly applicable to landing of a carrier-based aircraft. The speed-reducing and stopping device consists of an electromagnetic runway, a magnetic tail plate and a control system, wherein the electromagnetic runway is arranged in an aircraft landing runway; and the magnetic tail plate is arranged at the tail of the aircraft and can be unfolded or folded. In an aircraft landing process, the magnetic tail plate is unfolded, an electromagnet is electrified, and the direction of a magnetic pole of the magnetic tail plate is opposite to the direction of a magnetic pole of the electromagnetic runway; when the aircraft is close to the runway, the magnetic tail plate is attracted with the electromagnet of the runway, the aircraft is stopped from moving forwards, and the speed of the aircraft is sharply reduced, so that the aircraft can be safely landed within a short time and by a short distance. After the aircraft is stopped, the power of the electromagnet is failed or the current direction is changed, and the magnetic tail plate is separated from the electromagnetic runway and is folded, so that the aircraft can move to an objective position.

Description

technical field [0001] The invention relates to a deceleration and shutdown device for aircraft landing, and is especially suitable for the landing of carrier-based aircraft of an aircraft carrier. Background technique [0002] In order to stop the carrier-based aircraft in time on the deck, the landing deceleration stop device generally adopted is the aircraft tail hook aircraft carrier arresting cable deceleration device. But this deceleration shutdown device still has unsatisfactory part. One is the risk that the aircraft cannot be stopped due to the failure of the tail hook to hook the arresting wire; the second is that after the aircraft stops, full-time personnel on the aircraft carrier deck need to remove the arresting wire from the tail hook of the aircraft, which is time-consuming and inconvenient. There are safety hazards when the arresting cable rebounds; the third is the risk that the arresting cable may break; the fourth is that when the aircraft wheels pass th...

Problems solved by technology

One is the risk that the aircraft cannot be stopped due to the failure of the tail hook to hook the arresting wire; the second is that after the aircraft stops, full-time personnel on the aircraft carrier deck need to remove the arresting wire from the tail hook of the aircraft, which is time-consuming and inconvenient. There are safety hazards when the arresting cable rebounds; the third is the risk that the arresting cable may break; the fourth is that when the aircraft wheels pass through the arresting cable at high speed, it will produce violent vibrations, which is unsafe; fifth, the several arresting cables on the deck are not beautiful, affecting personnel walk normally
