Description
Technical field
The present invention relates to a kind of target for trajectory measurement, particularly a kind of trajectory measurement aerial suspension all-metal wire side target.
Background technology
Trajectory measurement target is generally a little calculate trajectory with the relative position of target center by measurement target drone kicks down.The perfect condition of target keeps at height that target surface is smooth, transfixion in the air.Common trajectory measurement target mainly contains target surface, framework, lifting bolt and securing member composition.Target surface is generally square nylon gauze, and framework is the square-shaped metal framework adopting metal tube welding fabrication, and target surface four limit is bundled in framework four limit by band respectively, and lifting bolt is threaded in framework corner for aerial suspension.Because nylon gauze is flexible body, and without any support in the middle part of target surface, when hanging high-altitude and using, high-altitude wind speed is large, and cause target surface to swing with the wind aloft, target center position is not fixed, thus has influence on the precision of trajectory measurement.This just proposes requirement to the design of aerial suspension target.
Summary of the invention
The object of the invention is to provide a kind of trajectory measurement aerial suspension all-metal wire side target, solves popular target and hangs and wave with the wind behind high-altitude and affect the problem of trajectory measurement precision.
A kind of trajectory measurement aerial suspension all-metal wire side target, comprising: lifting bolt and nylon cable tie, also comprise: tube and pipe of aluminium alloy A, tube and pipe of aluminium alloy B, PVC pipe, aluminium net, cross-shaped fastener of steel pipe scaffold and rotary buckle for steel pipe scaffold.Cross-shaped fastener of steel pipe scaffold and tube and pipe of aluminium alloy A respectively have four, with the clip that two crosses are staggered on each cross-shaped fastener of steel pipe scaffold, four end to end formation square frames of tube and pipe of aluminium alloy A, are fixedly connected with in two clips that one end of adjacent two tube and pipe of aluminium alloy A is placed in a cross-shaped fastener of steel pipe scaffold respectively.Rotary buckle for steel pipe scaffold totally 8, each rotary buckle for steel pipe scaffold can form clip at any angle with two; Tube and pipe of aluminium alloy B totally four and be inclined in square frame corner respectively, the two ends of each tube and pipe of aluminium alloy B are fixedly connected with by rotary buckle for steel pipe scaffold with adjacent two tube and pipe of aluminium alloy A respectively; A clip of rotary buckle for steel pipe scaffold and one end clamping of a tube and pipe of aluminium alloy B, another clip and tube and pipe of aluminium alloy A clamping.Two PVC pipes are placed on the center line anyhow of square frame respectively, the two ends of PVC pipe are placed in the interior also clamping of clip of two cross-shaped fastener of steel pipe scaffolds respectively, another clips of described two cross-shaped fastener of steel pipe scaffolds respectively with tube and pipe of aluminium alloy A clamping, two PVC pipes entreat formation cross structure in the frame.Aluminium net and square frame measure-alike, four limits of aluminium net and the tube and pipe of aluminium alloy of square frame are fixed by nylon cable tie, and the core of aluminium net to be placed on PVC pipe and to be fixed by nylon cable tie.Four lifting bolts are threaded with the corner of square frame respectively.
By the lifting bolt of square frame corner, utilize jacking equipment that target is suspended from predetermined altitude, and tension frame corner.When measuring trajectory, according to the relative position relation calculating trajectory of shell hole on target aluminium wire side apart from target center.When aluminium net is worn in attack, the shape retention properties that nylon gauze has compared by aluminium net, makes shell hole regular shape, is easier to the measurement to shell hole position.When in attack during PVC pipe, the characteristic that PVC pipe is easily destroyed ensure that whole aluminium net wire side is not torn.
This target all adopts general part, and structure is simple, is easy to assembling and maintenance.Owing to adopting thin lightweight aluminium net, target weight is little, is easy to aerial suspension; Aluminium net can not produce extensive damage after being subject to the shock of bullet, can improve the certainty of measurement of point of impact; Importantly windage is less, has increased substantially stability during aerial suspension.
