Keywords: aerodynamic lift, ascent trajectory, bifurcation, optimization

The possibility of a significant increase of a payload mass injected into an orbit using the qualitatively new type of optimal atmospheric ascent trajectories is demonstrated. Its qualitative distinction is caused mainly by the effect of the aerodynamic lift even if it is small as compared with the weight.
