How can you minimise drag on a rocket ship

WebAs long as you have useable energy in your ship, you can use it to accelerate indefinitely your propellant in the opposite direction you want to accelerate; this is how rockets work. The propellant is basically something that carries away linear momentum in one direction so that the ship can gain momentum in the opposite direction. Web13 de abr. de 2024 · Drag and Q look identical because c_D is a constant. All you have to do is put some functional form for it in the deriv() function and you can have them reach maxima at different times. Right now I have the thrust suddenly cut to zero at t_burn. I've set rtol = 1E-11 to minimize the impact on that non-smooth function.
