From the birth of jet plane so far the accident that causes of the turbine engine of bird strike aircraft never stopped, increasing along with jet power aircraft and flight is because the aircraft accident of bird strike aircraft accident and disaster also increases thereupon.Though be military jet airplane, civil aviaton's jet airplane with aerial bird strike, suck in the aircraft turbojet engine, all can cause the sudden mechanical breakdown of aircraft, the serious air crash that directly causes takes place; From recent newspaper, Internet report, the world all has everywhere to happen occasionally because the birds of bird strike aircraft suck the accident of aircraft turbojet engine; Solve the bird strike aircraft, the generation of stopping airplane crash has caused the concern of the world today.
The existence of birds is all arranged in human lives's space, the activity space sea level elevation of birds on high from several meters all be its action radius to the full kms of number, at peri-urban numerous sparrows, dove group are arranged; Various eagles in mountain forest; Coastal the seabirds such as sea-gull that circle in the air are arranged, even in the aerial threat that far flies all may cause aircraft navigation that has migratory birds such as various wild geese, swan to gather in groups band together everywhere of last km.From the plateau to the Plain, the birds that grow on trees from the continent to the ocean are engraved in when having the space of flying with their and are threatening aloft jet plane.Particularly the airport all is in trees, lawn and the pasture and water fish pond of greening vegetation around the airport of open area of outskirts of a town combination, it all is the place that various birds are looked for food and perch, a large amount of sparrows, the rock dove of peri-urban existence, has extremely strong adaptive capacity, birds flight in groups has sudden, the a slice of gathering in groups band together during flight still can be taken precautions against the management aspect in the airport.For beyond the airport, be in the open area of outskirts of a town combination, in the peri-urban growth numerous sparrows, dove group are arranged, have extremely strong adaptive capacity, a slice of gathering in groups band together during flight; Trees, lawn and the pasture and water fish pond of greening vegetation all are the places that various birds are looked for food and perch around the airport.For numerous flying birds in the mountain forest and large-scale eagle; What have everywhere aloft in addition that various migratory birds gather in groups band together far flies (wild goose, swan etc.).More some large-scale transient migrates in groups and flies in the convective zone on cloud layer, and radar can not find that aviator's sight line does not catch up with the speed of aircraft, is hard to guard against in fact;
At present, the known method that prevents the bird strike aircraft is all limited to and is taken off, when landing the finite space around the airport is taken precautions against, the high-wall trammel net is set around each airport runways, on the airport and be provided with the aerial flying bird that special personnel, equipment troop cooperate the strong sound wave device to tackle around the airport and become to catching up with, find that flying bird adopts the method for mode warn birds such as coal gas big gun, firecrackers.For example, international airport, Xiaoshan, Hangzhou is just set up sole duty at the initial stage of setting up and is driven bird team, drive the bird team member and adopt modes such as trammel net, coal gas big gun, firecrackers to drive bird throughout the year, employ millions of circles simultaneously and drive bird and a whole set of acoustic control machine equipment from external introduction car and drive flying bird around the airfield runway.Reach the purpose that becomes to catching up with the bird of taking off, when landing the bird of the airflight around the airport is discharged the flight of strong sound scaring, shoot dead by force in case of necessity and become to catching up with.All airports, various countries are preventing that the bird strike aircraft from all adopting similar approach for this reason, have employed the consumption of great amount of manpower and material resources, financial resources separately.Along with aircraft and flight constantly increase, from the plateau to the Plain, the wide birds activity space from the continent to the ocean, and all spaces have no idea at all to prevent that flying bird and aircraft impact from causing that the air crash of sudden turbo-machine mechanical breakdown takes place beyond on the airport.Just because of present technical method adopts the airport to defend bird strike aircraft method on every side all is extremely passive, and the strick precaution scope is little.So this orthodox method for many years worldwide all can not fully, effectively solve because the birds of bird strike aircraft suck the fact that the accident of aircraft turbojet engine takes place.From recent newspaper, Internet report, all have everywhere because the accident of the birds of bird strike aircraft suction aircraft turbojet engine happens occasionally in the world; Consequently human and birds are ended in defeat for both sidesboth suffer losses; Solve the accident of bird strike aircraft, the generation of stopping airplane crash has become world today's property difficult problem.
Summary of the invention
In order to overcome the existing deficiency of the method for bird strike aircraft birds suction aircraft turbojet engine, the passive situation that take precautions against change aspect, airport of preventing, fundamentally eliminate the generation of bird strike aircraft accident; The invention provides a kind of actv., prevent that effectively birds from sucking the method for aircraft turbojet engine comprehensively.This method has not only been guaranteed omnibearingly in the taking off of aircraft, landing and the whole flight way to prevent that effectively bird strike aircraft birds from sucking the aircraft turbojet engine, and has fundamentally been ensured the comprehensive safe flight of aircraft.
The technical solution adopted for the present invention to solve the technical problems is: the metal guard that fixedly mounts a protecting against shock in the front end air inflow point of the angle of rake turbojet engine of each jet airplane automotive gas turbine formula, the metal guard is tapered or trapezoidal according to the profile mechanism processing of the front end air inflow point of the angle of rake turbojet engine of aircraft gas turbines formula, taper or trapezoidal 30 ~ 90 degree that are; When taking off and the impeller high speed revolution of angle of rake turbine engine in-flight, the metal guard can guarantee that sufficient air communication crosses and can stop birds to suck the aircraft turbojet engine at the turbine engine front end; The metal guard is the taper of rocket head or sub warhead, can overcome many deficiencies of planar metal guard; Can reduce air resistance on taper or the trapezium structure, prevent bird strike, the breathing area greater than the turbo-machine admission port is arranged, prevent that with timeliness birds from sucking the purpose that the aircraft turbojet engine reaches in the influx that does not reduce air.
The invention has the beneficial effects as follows,
1, can in the airport, ensure the safety of taking off, landing of aircraft.
2, the omnibearing birds suction aircraft turbojet engine that effectively prevents in whole flight whole process guarantees aircraft safety flight.
