| Summary: | The results of experimental studies on nitrogen with an overpressure of 0,02 MPa resistojet propulsion
system of a small spacecraft with a porous structure weighing 45 g and an autonomous heating element
with a radius of 3 mm with a power consumption of up to 60 watts for a warm-up time of up to 300 s are
presented. The possibility of using a porous structure as a volumetric fuel gas pipeline with an increase
in heat transfer intensity has been experimentally proved and the actual specific heat capacity of the
porous structure has been determined. Taking into account the actual specific heat capacity, theoretical
studies of the mass and geometry of the porous structure in the resistojet composition are carried out,
optimal with respect to the autonomous heating element used by the power and the amount of fuel
heating in the range (573–1273) K. Taking into account the radius of the heating element, the fuel
temperature range (573–973) K corresponding to the optimal masses and radii of the porous structure
for the formation of the resistojet design layout is determined. |
