Path: StraightLine/ConstantThrust
% Compute the transit time and exhaust velocity for constant thrust Pass empty for muF to compute the optimal value which minimizes transfer time. If tank fraction if not entered it will be zero. Using a higher fuel fraction than optimal results in a longer transit time with lower specific impulse and power requirements. -------------------------------------------------------------------------- Form: [tF,uE,muE,muF] = TOFConstThrust(lambda,dF,sigma,muF,f) -------------------------------------------------------------------------- ------ Inputs ------ lambda (1,:) Payload fraction (mP/m0) dF (1,:) Distance (km) sigma (1,:) Jet specific power, W/kg muF (1,:) Fuel mass fraction (mF/m0), [] to compute f (1,1) Fuel tank fraction, default 0 ------- Outputs ------- tF (1,:) Minimum transfer time (s) uE (1,:) Required exhaust velocity (km/s) muE (1,:) Engine mass fraction (mE/m0) muF (1,:) Optimal fuel mass fraction (mF/m0) --------------------------------------------------------------------------
