Abstract
A kind of bullet speed-measuring method, it is characterized in that: at gun tube or other local installation one ultrasonic generators, one ultrasonic receiver is installed in fuse, if velocity of sound is C, the initial velocity of bullet is u, as u > c, successively two ultrasonic pulses are sent in pellet injection forward direction projectile flight direction, as u < c, after pellet injection, successively launch two ultrasonic pulses to projectile flight direction, its time interval is Δ T
1, when bullet leaps two ultrasonic pulses, or when two ultrasonic pulses surmount bullet, ultrasonic receiver all energy perception, its mistiming is Δ T
2, due to u Δ T
2=C Δ T
1, therefore
Description
Technical field: the present invention relates to a kind of bullet speed-measuring method, especially can be stored in the bullet speed-measuring method of Projectile Fuze control system inside by velocity information.
Background technology: in time faze, due to muzzle velocity deviation, can cause operating distance to have relatively large deviation, thus affect the fighting effect of bullet warhead.Known muzzle velocity assay method roughly has three kinds: one to be that sky tests the speed, and it by initial velocity information storage in fuze control system, can not can not be used for correction time fuze function range deviation; Two is that coil electromagnetism induction is tested the speed, and it needs to set up inductive coil outside gun tube mouth and bullet, and impact plays shape and gun tube profile; Three is that acceleration transducer integration tests the speed, and its disadvantage is that the precision tested the speed is not high, and in time faze, using value is little at present.
Summary of the invention: the object of the present invention is to provide and a kind ofly muzzle velocity determination can be stored in fuze control system inside for information about, coil need not be set up at gun tube and fuse outside again, a kind of bullet speed-measuring method of high precision result can also be obtained.
The object of the invention is to realize by following technical solution: a kind of bullet speed-measuring method, it is characterized in that: at gun tube or other local installation one ultrasonic generators, one ultrasonic receiver is installed in fuse, if velocity of sound is C, the initial velocity of bullet is u: as u > c, before pellet injection, first successively send two ultrasonic pulses by ultrasonic generator to projectile flight direction, its time is spaced apart Δ T
1, when after pellet injection, bullet successively will leap these two ultrasonic pulses and by ultrasonic receiver perception, its detecting period difference is Δ T
2, at this moment, the flying distance of bullet between two ultrasonic pulses is u Δ T
2, and the spacing between two ultrasonic pulses is C Δ T
1, due to u Δ T
2=C Δ T
1, therefore
as u < C, after pellet injection, more successively launch two ultrasonic pulses by ultrasonic generator to projectile flight direction, its time interval is also Δ T
1, at this moment, two ultrasound waves successively will surmount aloft bullet and by ultrasonic receiver perception, its detecting period difference is also Δ T
2, in like manner, due to u Δ T
2=C Δ T
1, therefore
Measure the initial velocity of bullet with the present invention, method is simple, and with low cost, rate accuracy is high, in fuse especially time faze, has good application value.
Embodiment: a kind of bullet speed-measuring method, it is characterized in that: at gun tube or other local installation one ultrasonic generators, one ultrasonic receiver is installed in fuse, if velocity of sound is C, the initial velocity of bullet is u: as u > c, before pellet injection, first successively send two ultrasonic pulses by ultrasonic generator to projectile flight direction, its time is spaced apart Δ T
1, when after pellet injection, bullet successively will leap these two ultrasonic pulses and by ultrasonic receiver perception, its detecting period difference is Δ T
2, at this moment, the flying distance of bullet between two ultrasonic pulses is u Δ T
2, and the spacing between two ultrasonic pulses is C Δ T
1, due to u Δ T
2=C Δ T
1, therefore
as u < C, after pellet injection, more successively launch two ultrasonic pulses by ultrasonic generator to projectile flight direction, its time interval is also Δ T
1, at this moment, two ultrasound waves successively will surmount aloft bullet and by ultrasonic receiver perception, its detecting period difference is also Δ T
2, in like manner, due to u Δ T
2=C Δ T
1, therefore
It is worthy of note: above-mentioned velocity of sound C is the speed that sound is propagated in atmosphere, is a known constant; Mistiming Δ T
1need preset and be stored in fuze control system inside; Mistiming Δ T
2measured by fuze control system;
net result also by fuze control system calculate, store, application.
