Abstract

The utility model discloses an aircraft can prevent to rush out device of runway when from taking off and land, include by a plurality of being " one " font arrange in proper order set up the bumper post that puts, set up carbon roller bearing between bumper post, bumper post group that the bearing of the piston cross shaft joint of bumper post top and piston cross shaft joint both sides constitutes, characterized by: the bumper post component is do not buried underground perpendicularly and is buried underground in the left and right both sides of runway in runway below and parallel, and the carbon roller bearing is higher than airport runway surface 2 -4cm. The utility model has the advantages that: simple structure, convenient operation, the take -off speed of aircraft can also can be accelerated to the runway of rushing out out of control in the time of can not only preventing that the aircraft from taking off and land when taking off, slow down when the descending taxiing speed of aircraft of aircraft.

Description

A kind of device that can prevent gunning off the runway during takeoff and landing
Technical field
The utility model relates to takeoff and landing, specifically a kind of device that can prevent gunning off the runway during takeoff and landing.
Background technology
Taking off of traditional aircraft does not have power-assisted, only takes off by engine power, takes off slow, and fuel oil power consumption is large; Mainly rely on parachute to produce resistance during aircraft landing, aircraft landing brake is slow.
For this reason, applicant in this case once disclosed a kind of device that can provide power-assisted and resistance to takeoff and landing with Chinese patent CN203714180U, this device is provided with damper leg at the sagging direct-burried of airstrip, carbon roller bearing and piston cross drive coupling, though this structure can realize the takeoff speed accelerating aircraft when aircraft normally takes off, slow down when aircraft landing the object of coasting speed of aircraft, but nose wheel angle is the straight angle 180 degree during aircraft safety landing, and when aircraft nose wheel angle is less than the straight angle (i.e. obtuse angle), aircraft is easily out of control to gun off the runway, dangerous huge, therefore the practice effect of this device is unsatisfactory.
Utility model content
The purpose of this utility model is for overcoming the deficiencies in the prior art, and a kind of device that can prevent gunning off the runway during takeoff and landing is provided, out of controlly when this device can not only prevent takeoff and landing to gun off the runway, the takeoff speed accelerating aircraft when aircraft normally takes off can also be realized, the object of the coasting speed of the aircraft that slows down when aircraft landing.
The technical scheme realizing the utility model object is:
A kind of device that can prevent gunning off the runway during takeoff and landing, comprise by multiple in " one " font order arrange setting damper leg, be arranged on the carbon roller bearing between damper leg, damper leg group that the bearing of the piston cross drive coupling above damper leg and piston cross drive coupling both sides is formed, unlike the prior art: damper leg group is embedded vertically at respectively below runway and is embedded in runway arranged on left and right sides with parallel, runway is that middle part is high, the low structure in both sides, carbon roller bearing higher than airport runway surface 2-4cm, wherein:
Bottom distance in the first damper leg group below runway between each carbon roller bearing and aircraft, the distance of two wheels is close;
Carbon roller bearing motion for the relative rotation respectively in second and third damper leg group of runway arranged on left and right sides, and contact with front-wheel bottom aircraft respectively;
The motor that the side of damper leg is provided with change speed gear box and is connected with change speed gear box, change speed gear box is connected with bearing.
Described runway arranged on left and right sides is slightly low 2-4cm in the middle of runway comparatively, and is provided with a drain tank at lower portion, and avoid has ponding in runway in rainy season weather.
Comprising 3-5 double acting oil gas damper leg in described each damper leg group, is prior art.
The length of described each carbon roller bearing is 4-5 rice.
During installation, under this device is embedded vertically at airfield runway and arranged on left and right sides, carbon roller bearing, higher than airfield runway ground 2-4cm, is arranged along airfield runway every 300 meters of intervals.
The working process of the utility model device is:
When aircraft is out of control, prepare to gun off the runway or sideslip time, drive carbon roller bearing to rotate to direction inside runway by electrical motor and change speed gear box, aircraft nose wheel produced and guides propelling thrust, aircraft is led back in normal runway, in straight angle Normal Take-Off And Landing;
When taking off, driving carbon roller bearing to operate in the same way to the direction of wheel turns when taking off by electrical motor and change speed gear box, to taking off generation power-assisted, reaching the object accelerating speed of taking off; When aircraft landing, drive carbon roller bearing to the direction reversed operation of wheel turns during aircraft landing by electrical motor and change speed gear box, produce resistance to aircraft landing, reach the object of the aircraft taxi speed that slows down.
The utility model has the advantages that: structure is simple, easy to operate, out of controlly when can not only prevent takeoff and landing to gun off the runway, can also can accelerate the takeoff speed of aircraft when taking off, the coasting speed of the aircraft that slows down during aircraft landing.
