EXPERIMENTAL STUDY ON THE GUIDING-DEFLECTION PERFORMANCE OF CONES
|
Abstract:
Guiding-deflection technique is one of efficient technical ways to protect engineering constructions against precision-guided weapons. In this paper, ductalloy guiding-deflection cones (GDC) are adopted, and simulated impact tests with 37 mm semi-armour piercing projectiles are carried out to test the guiding-deflection performance of the GDC structure. Test results indicate that the structure can make the projectile deflect more than 10 degrees, and the penetration depth into the target is reduced to less than its 1/3. On the basis of test results, the guiding-deflection mechanism of GDC as well as the test errors are analyzed, and a conclusion is reached that a space with as small resistance as possible behind the guiding-deflection structure is one of prerequisites to achieve large deflection angles. The guiding-deflection structure can be applied In some important engineering constructions of national defence and civil-air defence.
