Systems and methods of controlling solid propellant burn rate, propellant gas pressure, propellant gas pressure pulse shape, and propellant gas flow rate, rely on pulse width modulation of a control valve duty cycle. A control valve that is movable between a closed position and a full-open position is disposed downstream of, and in fluid communication with, a solid propellant gas generator. The solid propellant in the solid propellant gas generator is ignited, to thereby generate propellant gas. The control valve is moved between the closed position and ...
What is claimed is: 1. A method of controlling solid propellant burn rate, comprising the steps of:disposing the solid propellant in a vessel;disposing a control valve between, and in fluid communication with, the vessel and a propellant gas load, the control valve movable between a closed position and a full-open position;igniting the solid propellant in the vessel to thereby generate propellant gas;moving the control valve between the closed position, in which the propellant gas load is fluidly isolated from the vessel, and the full-open position, in w...
