Embodiment

[0036] The aircraft arresting system of the present invention is laid within the range of 247 meters in length at the southern end of an airport runway, and is used to arrest passenger aircraft of types such as Airbus 319 and Boeing 737-700. The airport has heavy and concentrated rainfall during the rainy season. Therefore the aircraft arresting system that is used for this airport according to the present invention is as follows:

[0037] The total length of the system is 241 meters. Among them, the buffer zone 105 is 110 meters long; the guide zone 102 is a slope with a length of 30 meters and a terminal height of 0.08 meters, with a slope of 0.27%; There are steps made of blocking units on both sides of the blocking area 106 . The system width is the runway width plus the shoulder width on both sides is 49 meters.

[0038] The deflector 104 is installed at the end of the guide area 102. The inclined surface of the deflector 104 is an aluminum plate with a thickness of 2 ...

Abstract

The invention provides a runway end airplane blocking system and is used for the technical field of airplane retardant safety. The runway end airplane blocking system comprises a buffer area, a guide area, a blocking area, a matched traffic lane and a drainage ditch. The gradient of the guide area is 0.16%-1%, a guide plate is installed at the rear end of the guide area, the blocking area is formed by laying a blocking unit body on a foundation in a specific mode, and the foundation of the blocking area is 0.05-0.15m lower than the tail end of the guide area. The width of the buffer area, the width of the guide area and the width of the blocking area all are not lower than the width of a runway and the width of runway shoulders on two sides. Vertical vibration of an airplane can be remarkably reduced after the airplane enters the blocking area by arrangement of the height of the tail end of the guide area, the capability of the blocking area resisting blowing of wake flow of the airplane is reinforced by arrangement of the guide plate, and the blocking unit body has specific compression strength characteristics, weather-proof characteristics and carrying characteristics, so that durability of the blocking area is improved.

Description

technical field [0001] The invention relates to the field of airport safety facilities, in particular to an aircraft arresting system at the end of a runway for stopping an aircraft or making the aircraft decelerate as safely and effectively as possible. Background technique [0002] At civilian and military airports, an aircraft overshooting the runway can have serious consequences. Laying an arresting system in the extension direction of the runway outside the end of the runway, so that the aircraft stops in the arresting system after a deceleration process that does not exceed the limit, is an effective method to reduce the degree of harm caused by the aircraft running out of the runway. The arresting system mainly relies on the aircraft wheels to crush compressible materials to obtain resistance to slow down the aircraft. The design and limitation of material properties, the configuration and size of the arresting system are the key to the arresting effect. The construct...
