Path: Propulsion/Rocket
% Compute masses for a single stage to produce the required delta-v. The structural fraction will limit the achievable delta-v. Type RocketMass for a demo of a LH2/LO2 rocket. Since version 2014.1 -------------------------------------------------------------------------- Form: [mF, mT, mS, e] = RocketMass( Isp, mP, fS, dV ) -------------------------------------------------------------------------- ------ Inputs ------ Isp (1,1) Specific impulse (sec) mP (1,1) Payload mass (kg) fS (1,1) Structural fraction dV (1,:) Required delta v (km/sec) ------- Outputs ------- mF (1,:) Fuel mass (kg) mT (1,:) Total mass (kg) mS (1,:) Structural mass (kg) e (1,:) Payload fraction -------------------------------------------------------------------------- Reference: Wiesel, W. E., Spaceflight Dynamics, McGraw-Hill, 1988, p. 187. --------------------------------------------------------------------------
