1. A method for cutting, in a non-through manner, a body of a thruster of an aerospace vehicle, using water jets, the method comprising a plurality of passes of a high-pressure water jet along the same cutting path extending across the external perimeter of the thruster body, the cutting path describing a closed loop circuit, and each water jet passage starting from a starting point located on the cutting path and stopping just after returning on the starting location,
wherein the starting point of each high-pressure water jet pass is different from the starting points of the other water jet passes.
