Aerodynamic (drag and lift) forces at 0 deg and 10 deg angle of attack on Titan in the (a) longitudinal x and (b) transverse y directions at the nominal wind speed of 1 m/s and on Earth in the (c) longitudinal x and (d) transverse y directions at a nominal wind speed of 7 m/s. Note that at 0 deg angle of attack, there is no lift force due to the symmetry of the balloon. Simulations show initial perturbations in force before reaching a cyclic steady state.
