Abstract
An end-burning grain of a solid gas-generating composition which may be a propellant for use in rocket motors, in which an elongate metal heat conductor is embedded to increase mass burning rate by the effect of heat transferred from the hot combustion gas to the unburned gas-generating composition through the heat conductor. The improvement resides in that the heat conductor is constituted of a plurality of relatively thin wires which are loosely twisted together. This heat conductor can produce greater extent of increase in the burning rate and has a mechanical strength sufficient for embedding in a practical grain.
