Abstract: The landing gear system is an important mechanism for the safe and stable landing of a lunar lander. In view of the variety of the initial conditions upon landing, the vehicle-level attenuation characteristics should be sufficiently verified under limited test conditions. Based on the experience of three kinds of related experiments during the Apollo era, we propose a test method employing a full-scale model in the Earth gravity field, without the need of designing or processing the test sample, or simulating other gravity field. The basic scheme for determine the test conditions can be formulated after statistical analysis of massive simulation results considering all main factors at the landing moment. The following aspects are discussed for the implementation of the experiment: the balancing of mass properties, the influence of the Earth gravity during the impact procedure, the simulation of topographic characteristics, the measuring parameters and the data processing requirement. The method provides a guidance to the experimental verification of the landing gear system, especially of its integrated attenuation properties.
