Abstract

A method, which uses real pressure, temperature and mass data obtained from real telemetry, to control the mixture ratio based on the change of the temperature set in its tanks, where the mixture ratio is defined by the ratio between the oxidant mass consumption by the fuel mass consumption. To achieve this, the space system in question must have a bipropellant propulsion system operating in blow-down mode containing independent temperature control systems for each tank. The method is related to the aerospace field, the application of this method is of interest to the areas of manufacturing and operation of space systems.

Abstract

The present invention patent application relates to a method using real pressure, temperature and mass data obtained from real telemetry to control the mixing ratio by altering the temperature set in its tanks, wherein, for the purposes of the present patent application, the mixing ratio is defined by the ratio between oxidant mass consumption and fuel mass consumption. To this end, the space system in question must have a bipropellant propulsion system operating in blowdown mode containing separate temperature control systems for each of the tanks. The present patent application relates to the field of space, and the application of this method is of interest in the areas of space system manufacturing and operation.
