Abstract
The utility model provides a spare device on the ground for an airplane landing stand, which is composed of a helpful falling vehicle of an airport runway, an inertia damping device, and a soft landing elastic cushion, wherein, the inertia damping device is arranged at both sides of the helpful falling vehicle of an airport runway, and the soft landing elastic cushion is arranged at the upper part of the helpful falling vehicle of an airport runway. The spare device on the ground for an airplane landing stand of the utility model has the characteristics of reasonable design, simple structure, easy manufacturing, high safety, convenient operation, etc., and can fully solve the problem that the occurrence of air accidents is resulted from the unsafety landing caused by the possible fault of the airplane landing stand.
Description
1, technical field
The utility model relates to a kind of airport aircraft safety forced landing device, specifically a kind of undercarriage ground emergency facility.
2, technical background
As everyone knows, aircraft by wing flight all is to carry out the ground landing by the alighting gear that is arranged on fuselage wing below, in order to reduce the flight resistance of aircraft, the aircraft of present various different purposes all adopts the built-in alighting gear of hydraulic pressure, alighting gear is opened by hydraulic efficiency pressure system during landing, hydraulic efficiency gear is with gear up during built on stilts, but in the record of world's air accident of plane accident, it is the faults that come from alighting gear that a lot of airplane crashes are arranged, because the fault of alighting gear makes the aircraft can't be normally in landing at the airport, only bleed off fuel oil, force-land on the airport by force, because aircraft does not have alighting gear, aircraft can not slide on airfield runway under aviator's manipulation, is not the blast on fire of colliding surface aircraft, flies off the runway exactly and above ground structure bumps against blast on fire, end product is the fatal crass always, and the aircraft of forced landing is very few on world's flight history safely because of alighting gear is not opened successfully.Up to the present, also there are not good way and device can solve the problem that is out of order and lands the airliner safely because of undercarriage of above-mentioned existence.
3, goal of the invention
The purpose of this utility model provides a kind of easily row simple in structure, reliable, can abdicate the undercarriage ground emergency facility of the aircraft safety landing of alighting gear fault.
The purpose of this utility model realizes in the following manner, on the aerocraft development history, someone once with Rail sliding car with sky in the rocket launching, the U.S. once carries space shuttle with large aircraft space shuttle is sent to space, no matter the former still is the latter, employed method is to drive another object of which movement that moves by a mobile object to reach the needed acceleration/accel of flight for it, as a same reason, the same combination with the object on the go of another motion of swiftly passing object slowed down by another object then or born acceleration and finish from moving to static overall process.
The utility model is realized according to above-mentioned principle, concrete scheme is that an airfield runway landing aid vehicle is set in the end of airfield runway, soft landing air bag or soft landing pad are set in airfield runway landing aid vehicle and are used to prevent the safe damping arm that aircraft is skidded off by inertia, when aircraft enters runway, airfield runway landing aid vehicle starts acceleration on airfield runway, when the sinking speed of the moving velocity of airfield runway landing aid vehicle and aircraft near the time, aircraft just can drop on the soft landing pad on airfield runway landing aid vehicle top, the aircraft double-vane is fixed by the inertia damping device simultaneously, after the total weight of aircraft is loaded in the airfield runway landing aid vehicle, airfield runway landing aid vehicle just begins to replace the alighting gear of aircraft to carry out braking deceleration, land a plane safely on the airport, when airfield runway landing aid vehicle carries aircraft after coming to a complete stop on the airport, the ground crew just can overhaul the alighting gear that breaks down, the alighting gear maintenance finishes and recovers to use, and airfield runway landing aid vehicle can or allow car body reduce height by the distortion of soft landing pad and withdraw under airframe.
Accompanying drawing 1 is overlooked the running condition scheme drawing for undercarriage ground emergency facility;
Accompanying drawing 2 is the plan structure scheme drawing of undercarriage ground emergency facility;
Accompanying drawing 3 is the main TV structure scheme drawing of undercarriage ground emergency facility.
4, description of drawings
Explain below with reference to Figure of description undercarriage of the present utility model ground emergency facility being done.
Undercarriage of the present utility model ground emergency facility, its structure is to be made of airfield runway landing aid vehicle 1, inertia damping device 2 and soft landing cushion 3, inertia damping device 2 is arranged on the both sides of airfield runway landing aid vehicle 1, and soft landing cushion 3 is arranged on the top of airfield runway landing aid vehicle 1.
5, embodiment
Undercarriage of the present utility model ground its processing and fabricating of emergency facility is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.Airfield runway landing aid vehicle can adopt car chassis transformation, and driving engine adopts General Motors driving engine or jet engine according to the speed of aircraft.The chassis of airfield runway landing aid vehicle also can be according to the structure design of aircraft, be designed to one do not have a wing but be used for the movable alighting gear of ground plane with the fuselage of jet supersonic plane.Can be processed into air bag or other elastomeric material about the soft landing cushion.The effect of inertia damping device is to prevent that aircraft from skidding off forward under action of inertia at airfield runway landing aid vehicle glancing impact.
Undercarriage of the present utility model ground emergency facility is compared with prior art, have reasonable in design, simple in structure, be easy to processing, characteristics such as safe and reliable, easy to use, can not air crash that safe falling causes generation in case can solve fully that the aircraft alighting gear breaks down.Thereby, have good value for applications.
Except that the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
Claims (1)
1. undercarriage ground emergency facility, comprise airfield runway landing aid vehicle, inertia damping device and soft landing cushion, it is characterized in that the inertia damping device is arranged on the both sides of airfield runway landing aid vehicle, the soft landing cushion is arranged on the top of airfield runway landing aid vehicle.
