Abstract

A gas generator adapted to be disposed in a rear part of a projectile for increasing the flight range thereof, includes a housing defining a combustion chamber and having a bottom and a longitudinal axis; a fuel accommodated in the combustion chamber; an outlet opening provided in the housing bottom for passage of combustion gases generated in the combustion chamber upon combustion of the fuel; and a plastic fuel-supporting tube extending axially from the outlet opening into the combustion chamber. The plastic material of the fuel-supporting tube is selected such that upon combustion of the fuel aided by a gas pressure of a projectile propellant and by a drag effect, the fuel-supporting tube is deformed and driven out of the outlet opening.
