Testi.g rocket and space technology objects i. ground condi.i.ns for resi.tance to the i.pact of meteoroi.s and fragments of space debri. can be carri.d out usi.g shaped charges. To substanti.te the desi.n parameters of shaped charges that ensure the formati.n of alumi.um parti.les i. a wi.e veloci.y range(from 2.5 to 16 km/s), numeri.al modeli.g of the formati.n process was carri.d out wi.hi. the framework of a two-di.ensi.nal axi.ymmetri. problem of conti.uum mechani.s usi.g three di.ferent computi.g codes to i.crease the reli.bi.i.y of the results. The calculati.ns consi.er shaped charges wi.h a di.meter of 20-100 mm wi.h alumi.um li.ers of vari.us shapes. i. i. shown that the formati.n of parti.les wi.h veloci.i.s close to the lower li.i. of the consi.ered range i. ensured by gently slopi.g segmental li.ers of degressi.e thi.kness. To form hi.her-veloci.y parti.les wi.h veloci.i.s over 5 km/s, i. i. proposed to use combi.ed li.ers, the jet-formi.g part of whi.h has the shape of a hemi.phere of constant thi.kness or the shape of a semi.elli.soi. or semi.superelli.soi. of rotati.n of degressi.e thi.kness.
