A soft recovery system for artillery shell is a setup for testing survival of fuzes electronics during high firing shock. The setup comprises of long tube containing sections of high-pressure air, that decelerates the high velocity shell in a controlled manner. Design and sizing of the recovery tubes involves solution of gas dynamics equations and shock movements as shell interacts with internal diaphragm and compressed air columns. Input for the design and sizing software is muzzle velocity of shell, its inertial properties, location of compressed air columns and rupture strength of diaphragm. The output is time history of shock movement, pressure distribution and shell deceleration.
