Abstract

The article considers an opportunity of gas-dynamic acceleration of body from the initial zero velocity till the finite velocity: five kilometers per second. When the gas flow rate of the body pre-acceleration reaches one kilometer per second, the body is accelerated at the front of the explosion wave propagating along the coils of the hexogen spiral. This wave accelerates the body and, finally, it reaches the velocity of five kilometers per second. The accelerated body has mass one-tenth of a kilogram and diameter eleven and three tenths of a millimeter. Acceleration length is six meters. At the slope of the spiral to the horizon equal to seventy degrees the flight range of the body is equal to sixteen hundred kilometers and the maximum height of the flight is eleven hundred kilometers.
