METHOD FOR DELIVERING A LIQUID PRESSURISED BY THE COMBUSTION GASES FROM AT LEAST ONE PYROTECHNIC CHARGE

摘要

A method for delivering a liquid contained in a reservoir, the reservoir having a port for delivering the liquid which is closed off by a blow-out disk that is removable at a threshold pressure applied to the liquid, includes: the combustion of a pyrotechnic charge to generate combustion gases, the pressurization of the liquid by the combustion gases, and the removal of the removable blow-out disk from the delivery port and the delivery of the pressurized liquid. The flow rate of generated combustion gases during the delivery of the liquid ensures virtually constant pressurization of the liquid and thus the delivery of the liquid at a virtually constant flow rate. The pressure of the liquid during the delivery of the liquid varying only by a maximum of +/−30% with respect to its initial value at the time at which the blow-out disk is removed
