CN103353264A - Delayed fuse capable of igniting according to set height - Google Patents

Abstract

The invention relates to a delayed fuse capable of igniting according to a set height, which belongs to the technical field of fuses. The delayed fuse comprises a height judgment module, a binding module, a GPS (global position system) module and a starting module, wherein the binding module and the GPS module are connected with the height judgment module respectively through data lines, and transfer height information to the height judgment module respectively; the height judgment module is connected with the starting module through the data line and sends a starting signal to the starting module; the starting module is connected with a starting switch wire of a firing circuit; the starting module controls on-off of the starting switch of the firing circuit. The delayed fuse, disclosed by the invention, abandons the design thought that a traditional fuse starts to ignite according to preset time, fundamentally solves the technical difficulty that the error of a trajectory height calculated through the flying time is increased with the increase in range, and can be widely applicable to delayed ignition of civil rocket projectiles.

Description

A kind of time-delay fuze according to the setting height igniting

Technical field

The present invention relates to a kind of time-delay fuze according to the setting height igniting, belong to the Fuze Technology field.

Background technology

It is a kind of novel artificially triggered lightning means that metal wire draws the thunder bullet, and drawing the thunder bullet in proper height control, to carry out the operation of metal wire unwrapping wire be to determine to draw one of key factor of thunder operation success.The time-delay line-putting method that tradition is drawn the thunder bullet is, the Best Times that at first starts according to the corresponding relation computation delay that draws thunder bullet ballistic ordinate and flight time, by set-up time time-delay fuze within drawing the thunder bullet, before emission, bind in advance in the angle of incidence time-delay fuze with calculating good start-up time delay, draw thunder bullet time from launch time-delay fuze and begin timing, start the metal wire unwrapping wire after reaching the ticket reserving time, finish and draw the thunder operation.But increase along with drawing the thunder bullet flight time, and then the impact that has strengthened the objective factors such as trajectory environment, make the flight time calculate that the error of ballistic ordinate increases thereupon, traditional time delays fuse has become as drawing the civil rocket bullet such as thunder bullet important restraining factors in the tele direction development.

Summary of the invention

The objective of the invention is to calculate that by the flight time error of ballistic ordinate can increase along with the increase of range in order to solve traditional time delays fuse, thereby provide a kind of time-delay fuze according to setting height igniting, the large problem of metal wire unwrapping wire height parallax error when avoiding long-range delivery to draw the thunder bullet.

The objective of the invention is to be achieved through the following technical solutions:

A kind of time-delay fuze according to the setting height igniting of the present invention comprises height judge module, bookbinding module, gps satellite locating module, starts module,

The gps satellite locating module is measured in real time and is drawn the residing height above sea level of thunder bullet, and this height above sea level data transmission module is passed to the height judge module;

The bookbinding module receives the elevation information bookbinding, and this altitude information is transferred to the height judge module;

The height judge module stores bookbinding module height comparison information, and receive in real time the height above sea level information of gps satellite locating module, when judging the height comparison information of the satisfied bookbinding of the height above sea level information module that the gps satellite locating module imports in real time, send enabling signal to starting module;

Instant control point ignition circuit igniting after the enabling signal of startup module reception height judge module;

The bookbinding module links to each other with the height judge module by data wire respectively with the gps satellite locating module, and bookbinding module and gps satellite location are respectively to height judge module transmission elevation information; The height judge module links to each other with the startup module by data wire, and the height judge module sends enabling signal to starting module; Start module and be connected with the starting switch wire of firing circuit, the starting switch that starts the module controls firing circuit is opened.

The course of work

Before drawing the emission of thunder bullet, by bookbinding module bookbinding height comparison information, the bookbinding module sends to the height judge module with the height comparison information, and the height judge module should the height comparison information be stored; The gps satellite locating module is measured in real time and is drawn the residing height above sea level of thunder bullet, and with this height above sea level data transmission module pass to the height judge module, when the height judge module is judged the height comparison information of the satisfied bookbinding of the height above sea level information module that the gps satellite locating module imports in real time, send enabling signal to starting module; Instant control point ignition circuit igniting after the enabling signal of startup module reception height judge module, and then finish and draw the thunder operation.

Beneficial effect

Time-delay fuze of the present invention, abandoned the mentality of designing of passing through the Preset Time starting ignition in traditional fuse, solved by the flight time at all and calculated the technological difficulties that the error of ballistic ordinate can increase along with the increase of range, the present invention can be widely used in the delayed firing of civil rocket bullet.
