Description

Aircraft is landing pad on the ground

The utility model relates to aviation field, a kind of " aircraft is landing pad on the ground ".

Since the own aircraft, the taking-off and landing of aircraft, all be by with the alighting gear of aircraft one, general front is one group of two tire, the back is two group four to eight tire.In the alighting gear if wherein have one group malfunctioning, lay and open do not get off, landing has just become problem.Although incidence is very low, this problem causes the massive losses of life, property in case generation will bring huge disaster.This is a great problem in the aircraft safety.

In order to address this problem, the common practice can only be taked so-called " emergency landing ", the method that crashlands under the assurance of multiple measure after nose-gear is malfunctioning.This needs the airport to be in a state of emergency, as: China's TV play " emergency landing " is exactly true illustration of China.From organize and direct, the high concentration of lot of manpower and material resources such as safety facilities, fire-fighting are explosion-proof, medical aid and financial resources at the scene, just can reach emergent degree.However also do not hold successfully, severest consequences still inevitably can take place.So what people worried most in aviation is the landing safety problem, it is crucial all recognizing alighting gear altogether, what worry most is gear extension failure, that is afraid of a point failure also can bring stress and loss, never be resolved to this invisible pressure that causes on the passenger mentality for a long time, the aircraft landing air crash is still inevitable.

The purpose of this utility model provides the ground landing pad that is arranged on a kind of and the aircraft allosome, undercarriage is in a single day malfunctioning, can guarantee the as usual safe falling of aircraft, even the alighting gear of the aircraft safe falling that also can do as usual under the situation that fails to lay down of all not opening.

The purpose of this utility model is achieved like this: the skid of a similar undercarriage tire layout, i.e. and one group of tire in front, the six groups of tires in back; A guide chamber is arranged in the skid of the place ahead; An abutting plate is arranged in addition, and the running roller by both sides is located on the track above the skid, and afterbody has upper slide rest.When aircraft need utilize that on the ground landing pad lands, at first it is placed on the landing point position of airport airstrip the direction that has the people to operate front-wheel in the guide chamber, drift off the runway not after making aircraft and landing pad contacting.At first keep the abutting plate of certain angle to contact during aircraft landing with the skid track, move ahead along track simultaneously afterwards and cushion, whereabouts along with plane nose, abutting plate progressively also is tending towards lying on the skid, at this moment skid has also begun to travel forward under the effect of inertia of aircraft in advance, and moment, skid, abutting plate, aircraft three became one, and advanced simultaneously, up to till on the runway left alone without help time, landing mission is all finished.

Concrete structure of the present utility model is provided by following drawings and Examples.

Accompanying drawing 1 is the lateral plan according to the aircraft ground landing pad that the utility model proposes.

Accompanying drawing 2 is the back views according to the aircraft ground landing pad that the utility model proposes.

Below in conjunction with detail and the working condition of accompanying drawing detailed description according to the aircraft ground landing pad that the utility model proposes.

From accompanying drawing 1 as can be seen the skid of this ground landing pad (1) bottom front tyre (2), rear tyre (3) are arranged, there is " pillow " (5), buffer limiter (6), the anti-guide piece (7) of exceeding the bounds of parallel double track (4) and transverse belt circular arc the top, also has tail wheel (8), towing hook (9), guide chamber (10) in addition; There are bearing pin (12) and running roller (13) in both sides in the middle of the abutting plate of semicircle flute profile (11), there are some in the half slot also with the hanging type rubber tape (14) of identical radian measure, afterbody has upper slide rest (15), angle delimiter (16) and preceding single-wheel (17), the back two-wheel (18) of adjustable angle joint, there is wing limiting device (19) to move forward and backward with fixing along slideway (20) in both sides, adhesive tape (22) is arranged on the Eight characters frame (21), navigation indicator lamp (23) is arranged foremost, have vertical curve ruler (20), anti-back to play draw-in groove (25) in the middle of the back, back.

From accompanying drawing 2 as can be seen this aircraft between the wide adhesive tape of landing pad and the base plate (26) a crescent moon space (27) is arranged on the ground, wide adhesive tape all is fixed on the edge of base plate, the radian of its maintenance is all identical, radian at line of centers A point position and upper slide rest is identical, and all on a cambered surface, its radian diameter S suitably gets final product greater than the maximum fuselage diameter of passenger plane at present; Tire layout B wheel, C wheel are the two groups of compositions in front and back, and D takes turns, E takes turns in the outside, respectively is one group.Lifting mechanism (28) (29) is arranged on all wheel carrier supports, and its height H 1, H2 can regulate as required.

Embodiment:

1, the nose-gear of aircraft is malfunctioning.Can utilize the back alighting gear of aircraft itself to cooperate landing simultaneously during landing simultaneously with ground landing pad (1).Landing pad ornaments on the ground on the position of the aircraft normal landing point of runway, still open the back alighting gear of self before the aircraft landing earlier, after treating that tire lands, aircraft keeps certain angle to advance, and docks with in front the abutting plate (11) of ground landing pad maintenance respective angles just.And then three kinds of actions are arranged afterwards: the one, belly is to contact with high strength flexible glue band in the abutting plate, because adhesive tape can change with the fuselage diameter, no matter the fuselage diameter size can both make the radian of adhesive tape consistent with the fuselage radian, reach and simultaneously very identical soft contact of all adhesive tapes; The 2nd, contact back abutting plate (11) is under the coherence effect of aircraft, abutting plate begins to move ahead naturally, running roller (13) can only move ahead along rail under the effect of anti-device (7) of exceeding the bounds, and ride over curve ruler (20) in tail wheel (8) groove with before the abutting plate and then progressively raise simultaneously, after treating the abutting plate front and " pillow " (5) contacting, tail wheel (8) also enters in the draw-in groove simultaneously, reaches the purpose of anti-back bullet; The 3rd, in advance along track (4), skid (1) also can produce motion simultaneously at abutting plate (11).Its tangible aircraft and abutting plate (11) when docking skid also produced motion simultaneously, just kinematic velocity is progressively accelerated, and up to the flight of aircraft stop, promptly finishes landing task.Hang on the towing hook (9) with trailer afterwards, be dragged to the appropriate location place under repair, replace this aircraft ground landing pad stand-by again.
