Investigation on soft landing impact test of scale lunar lander model

According to the disadvantages of soft landing in two impact tests, the lunar lander full scale model within the moon gravitational field and 1/6 scale model within gravity field of the earth, the passage provides a new approach for the impact test of 1/3 scale model within gravity field of the earth. Test principle and test scheme is analyzed. Scale model prototype of the lunar lander is designed. Emulated lunar soil is prepared in terms of volcanic ash as raw material, and its mechanics performance is tested. Crushing test of selected aluminum honeycomb buffer material is analyzed as well. Also the measurement requirement of the data test is analyzed. The whole test system is verified and analyzed. Test results show that the test system presented in this test could simulate the soft landing process on the moon surface by the lunar lander. The overload would arrive minimum when the lunar lander is landing along the downhill on the symmetric mode, at the same, the rigid foot pad would not apply to lunar lander.
