TWO-CASCADE BALLISTIC INSTALLATION Russian patent published in 2014 - IPC F41F1/00 

FIELD: testing equipment.

SUBSTANCE: invention relates to the field of testing equipment and is designed to increase initial speeds of missile flight in process of experimental trial of new equipment with usage of tube powder ballistic installations. A two-cascade ballistic installation comprises a tube with a charging chamber, the main charge installed in it with an initiation device, a piston, an additional charge with an ignition device. The piston is placed at the outlet from the charging chamber with the possibility of movement only in direction towards the missile. The additional charge is installed in the tube between the piston and the missile. The main and additional charges are made of powder, and the main charge initiation facility - in the form of an extended explosive charge placed coaxially inside the main charge, made as capable of initiation with the specified delay relative to the moment of ignition of the additional charge ignited in the fixed condition.

EFFECT: invention provides for higher reliability of high speeds of missile flight with existing limitations to maximum permissible values of pressure in a tube and missile overload.
