Abstract	Choosing the right landing-leg design is crucial for the safe and cost-effective reuse of rockets. This report compares three main types of landing legs—telescopic, hinged, and lattice—for a reusable launch vehicle. By analysing data from over 120 landings, we found that the lattice structure offers the best overall performance. It significantly reduces the forces during impact and provides better stability on uneven ground compared to the other designs. This makes the lattice leg a superior choice for improving landing reliability and efficiency.
