Description
Technical field
The present invention relates to a kind of radome localization method of no special tooling, belongs to and radome of fighter is positioned outside a kind of frame
Method.
Background technology
According to requests for alternations, it is necessary to change the outfit the radome structure of the aircraft of certain type delivered general assembly for radome.Radome is determined
It need to ensure that the concentricity of its axis and the theoretical axis under aircraft axes requires to be φ D during position.But determine because aircraft can not return frame
Position, it is impossible to ensure its positioning accuracy using special tooling, it is therefore necessary to formulate a set of scene that is suitable for and realize thunder without special tooling
Up to the method for cover positioning.
The content of the invention
The problem of to overcome above-mentioned radome location and installation, the present invention provide a kind of radome positioning side of no special tooling
Method, the situation without special tooling can meet the positioning requirements of radome outside frame.
Since radome rear portion is linked on the deckle board of fuselage, its rear portion has been fixed with respect to the position of aircraft, radome
With respect to its theoretical axis concentricity just only and its tip relative theory position deviation it is related.Therefore radome cusp need to
Its theoretical center is the center of circle, can ensure positioning requirements in the circle of a diameter of Φ D.
The technical scheme is that to radome cusp with respect to its theoretical center in the inclined of levelness and height both direction
Shifting amount is respectively controlled, so as to finally ensure the positioning requirements of radome axis.
The present invention adopts the following technical scheme that to realize above-mentioned technical purpose：
A kind of radome localization method of no special tooling, will using level meter first with airplane horizontal survey principle
Airframe is adjusted to horizontality, and radome rear portion is linked on the deckle board of fuselage；
Then member center B on fuselage is measured using level meter and levelling rod or long steel ruler, is recorded in level meter
In the numerical value H of the levelling rod read or long steel rulerB；Radome cusp A is measured with same method again, record numerical value HA；
Radome cusp A is adjusted, is made
Meanwhile a thin cotton thread is drawn above radome, thin cotton thread leading portion passes through two marks on fuselage central axes
Point, the thin cotton thread other end carry weight, around hanging down after one thin rod in radome front end；Adjust the left and right position of radome cusp
Put, be not more than its distance in the horizontal direction away from cotton thread left and right deviation
After meeting above-mentioned requirements coaxiality deviation of the radome axis with respect to its theoretical axis can be met in φ D scopes
It is interior.
Further, radome is lifted in installation neighbouring position using bracket.
Its principle is as follows：According to trigonometric function calculate cusp in the horizontal direction and short transverse relative theory position offset
Amount control existsWithin in the case of can ensure the deviation requirement of radome axis relative theory axis.
When operating at the scene, aircraft is adjusted to horizontality first, then utilizes level meter difference instrumentation radar cover point
The relative altitude of certain member center B on point A and fuselage, the height of adjustment radar cusp make the difference in height of A, B be
So ensure that offset of the radome cusp in short transverse；Meanwhile a thin cotton thread, thin cotton thread are drawn above radome
There is weight by two punctuates on fuselage central axes, its end system after exceptionally straight, under gravity, thin cotton thread bypasses
Hang down after one thin rod in the front end of radome, the plane where this ensures that cotton thread is located on the plane of symmetry of fuselage.Adjust thunder
Up to the position of cover front end, it is not more than left and right deviation distances of its cusp A away from the thin cotton thread to hang downSo ensure that
Radome offset in the horizontal direction.
Beneficial effects of the present invention：
This method employ by radome concentricity be converted into scene be relatively easy to measurement radome cusp left and right and
Height tolerance, and adjustment is measured by the handy instrument in the scene such as level meter and thin cotton thread, it thereby may be ensured that thunder
Up to the positioning requirements of cover, solve the problems, such as that field retrofit can not be positioned using frock.
Brief description of the drawings
Fig. 1 is the schematic diagram that cusp offset of the present invention is converted into left and right and short transverse offset；
Fig. 2 is the side view of control radar cover position of cusp of the present invention.
1--- radomes in figure, 2--- fuselages, 3- ends carry the thin cotton thread of weight, A--- radome cusps, B--- machines
Certain member center with it, the difference in height of Δ H---A points and B points.
Embodiment
The method of the outer station keeping radar cover of this is illustrated below in conjunction with the accompanying drawings.
First with airplane horizontal survey principle, airframe is adjusted to horizontality using level meter, and by radar
Cover rear portion is linked on the deckle board of fuselage, bracket can be used to lift radome in installation site substantially.
Then certain member center B on fuselage is measured using level meter and levelling rod or long steel ruler, is recorded in level
The levelling rod or the numerical value H of long steel ruler read in instrumentB；Radome cusp A is measured with same method again, records numerical value
HA；Radome cusp A is adjusted, is made
Meanwhile a thin cotton thread is drawn above radome, thin cotton thread leading portion passes through two marks on fuselage central axes
Point, the thin cotton thread other end carry weight, around hanging down after one thin rod in radome front end；Adjust the left and right position of radome cusp
Put, be not more than its distance in the horizontal direction away from cotton thread left and right deviation
After meeting above-mentioned requirements coaxiality deviation of the radome axis with respect to its theoretical axis can be met in φ D scopes
It is interior.
Its principle is as follows：The schematic diagram first according to Fig. 1, according to trigonometric function calculate cusp in the horizontal direction and height
The offset control of direction relative theory position existsWithin in the case of can ensure radome axis relative theory axis
Deviation requirement.
When operating at the scene, aircraft is adjusted to horizontality first, then utilizes level meter difference instrumentation radar cover point
The relative altitude of certain member center B on point A and fuselage, the height of adjustment radar cusp make the difference in height of A, B beSo ensure that offset of the radome cusp in short transverse.
Meanwhile thin cotton thread 3 of the end with weight is drawn above radome, by positioned at fuselage after thin cotton thread is exceptionally straight
There are weight in two punctuates on central axes, its end system, under gravity, thin cotton thread bypass one thin rod after in radome
Front end hang down, the plane where this ensures that cotton thread is located on the plane of symmetry of fuselage.The position of radome front end is adjusted, makes it
Left and right deviation distances of the cusp A away from the thin cotton thread to hang down is not more thanSo ensure that radome is in the horizontal direction partially
Shifting amount.
