Description

A kind of ammunition power kills and wounds volume evaluation method

Technical field

The present invention relates to ammunition power assessment technique field, especially relate to a kind of ammunition power and kill and wound volume evaluation method.

Background technology

According to GJB2425 conventional Weapon warhead power test method, GJB4225 howitzer qualification test code, GJB3197 shell test method, howitzer lethal power adopts methods such as killing and wounding parameter, lethal radius, lethal area to carry out showing and evaluating usually.Killing and wounding parameter mainly by the static research technique igniting projectile measurement, obtaining the parameter such as distributed number, mass distribution, space distribution, Initial Velocities of Fragments of bulletfragment directly as killing and wounding parameter; Lethal radius mainly by with bullet be the center of circle different radii in arrange the dummy of simulation size, according to different distance fragmentation distributed number, with dummy at least in the criterion of one piece of fragmentation, calculate the lethal radius of fragmentation; Lethal area is then the area integral to the kill probability killing and wounding different area infinitesimal in plane.

Above-mentioned various evaluation methods respectively have following relative merits:

Employing kills and wounds expressed as parameters, and advantage is each single index of easily understanding fragmentation directly perceived.Subject matter one is that fragment emission characteristic distributions does not take into full account, two is multi objective (namely Fragment Velocities and weight amount distribute) incoherent expression, not easily compares the size of two kinds of bullet powers.Therefore, to kill and wound parameter to evaluate shell fragment lethal power, there are two aspects not enough as test rating: Article 1 shortcoming is, can not fully demonstrate the precise effect of ammunition power; Article 2 shortcoming is, not by lethal area and volume computing, is difficult to the height telling bullet power from these indexs.Such as have the bullet of two kinds of different Fragment Velocities and weight amount distribution, the lethal power being difficult to say that bullet is larger.

Adopt single lethal radius to represent no matter adopt which kind of lethal radius such as intensive or effective, one is except axle becomes 90 degree of directions with bullet, other directions not with consideration; Two is sizes that this single lethal radius definitely can not reflect bullet power; Three is for yield-to-weight ratio comparatively, judges by accident sometimes.Such as, the bullet that the large dense lethal radius of fragmentation is little, probably its lethal power is greater than the large bullet of fragmentation dense lethal radius.

Employing lethal area represents, advantage is that it meets two basic demands of lethal power test rating.But one of shortcoming, is only suitable for power qualification ground or waterborne target etc. being killed and wounded to plane, can not be suitable for and identifies the power of aerial target simultaneously; Shortcoming two, adopt the lethal area on same bullet axle plumb cut, do not conform to the actual conditions, adopt and the lethal area in the actual usual application of slice conformed to, along with the difference of shell bullet kind, terminal-velocity isoparametric different result of calculation in the angle of fall differs greatly, and therefore can not reflect bullet lethal power comprehensively.

The test rating of state's lethal powers such as Eastern Europe, with existing close of China, the western countries such as the U.S. and our standard are distinguished to some extent.The state such as the U.S., Belgium, as the test rating of fragmentation damage power, multiplex lethal area, the states such as Eastern Europe use lethal area.As can be seen here, lethal area is the generic inspection index of countries in the world lethal power, and, the lethal area of this inspection, the overwhelming majority adopts trial value, the target of test is dummy or truck target etc., the roughly the same fan-shaped target method of concrete test or almost fan target method, but depositing speed, the angle of fall and putting height etc. of test bullet may be different.
