The problem of acceleration in a cylindrical channel by a compressed gas (in particular, by the detonation products of a mixture of acetylene and oxygen) of a thin flat striker is related to the problem of a falling sheet of paper", since the movement of the striker in the channel is unstable with respect to the lateral displacement. This can lead to a violation of the symmetry of the flight of the striker, its skew and a sharp decrease in the achieved speed of the striker. The possibility of preserving the orientation of the striker by limiting its lateral displacement by a uniform arrangement on the inner surface of the channel (on the forming surface) of several thin strands of polymer fishing line is experimentally shown.
