% Designs a blowdown system. If gas constant is omitted, Helium will be assumed. Typical tank pressures are 300-400 psi BOL and 100 psi EOL. -------------------------------------------------------------------------- Form: [v, mP] = BDDesign( mF, rhoF, tNom, pI, pF, rP ) -------------------------------------------------------------------------- ------ Inputs ------ mF (1,:) Mass of fuel (kg) rhoF (1,1) Density of fuel (kg/m^3) tNom (1,1) Nominal temperature (K) pI (1,1) Initial pressure (N/m^2) pF (1,1) Final pressure (N/m^2) rP (1,1) Gas constant of pressurant ------- Outputs ------- v (1,:) Volume (m^3) mP (1,:) Required mass of pressurant (kg) -------------------------------------------------------------------------- References: Larson and Wertz, Space Mission Analysis and Design, Second Edition, Space Technology Library, Microcosm, Inc., 1996.
