#Lunar lander model full#
They are landing impact test by full scale model with the moon gravitational field and 1/6 scale model within earth gravity field. So far, both domestic and overseas, the lunar lander landing impact test mainly has two methods. At the same time, optimization, adjustment and improvement of the lander structure would make the structure more reasonable, stable and advantageous. It is necessary to conduct the simulation test on the ground completely and evaluate the lunar lander soft landing buffer performance and soft landing stability before the launch. Although the current precise navigation and point landing technology are advanced, the lunar lander still has certain risk in landing stage performance due to the particularity of the lunar surface environment, complexity and landing speed and gesture may all bring a certain degree of uncertainty. Soft landing on the surface of the moon would be the most important progress in the whole project. 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.
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 whole test system is verified and analyzed. Also the measurement requirement of the data test is analyzed. Crushing test of selected aluminum honeycomb buffer material is analyzed as well. Emulated lunar soil is prepared in terms of volcanic ash as raw material, and its mechanics performance is tested. Scale model prototype of the lunar lander is designed. Test principle and test scheme is analyzed. 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.
