Path: Orbit/StraightLine
% Computes power and thrust as a function of specific power. Assumes constant acceleration to the midpoint then constant deceleration. It automatically limits results to sigma's that will work. Type ThrustElectric for a demo for an Alpha Centauri mission. -------------------------------------------------------------------------- Form: [thrust, sigma, mE, mF, power, dV] = ThrustElectric( tM, d, uE, sigma, f, eta, mP ) -------------------------------------------------------------------------- ------ Inputs ------ tM (1,1) Mission time (sec) d (1,1) Distance (km) uE (1,1) Exhaust velocity (km/s) sigma (1,:) Specific power (W/kg) f (1,1) Structural fraction (kg/kg fuel) eta (1,1) Engine efficiency mP (1,1) Mass of spacecraft not including fuel, fuel tankage or engine ------- Outputs ------- thrust (1,:) Maximum thrust (N) sigma (1,:) Specific power (W/kg) mE (1,:) Engine mass (kg) mF (1,:) Fuel mass (kg) vMax (1,1) Maximum velocity power (1,:) Engine power (W) dV (1,1) Delta V (km/s) --------------------------------------------------------------------------
