Design and Optimization of an Active Leveling System Actuator for Lunar Lander Application

This work proposes a systematic methodology for designing an active leveling system (ALS) actuator lunar landing application. The ALS is integrated into inverted tripod leg layout, exploiting honeycomb crushable damper as shock absorber. proposed fitted within the leg’s primary strut and features custom permanent-magnet synchronous machine rigidly coupled with lead screw. aims to both provide proper deployment functioning compensate different absorber deformations during landing. dynamic behavior simulated through parameterized multi-body model investigate scenarios. First, parametric sensitivity approach used optimize transmission electric characteristics. Then, motor numerically validated optimized electromagnetic finite element analysis. To validate design methodology, virtual test bench assess performances under load It found that able yield compact, well-sized which EL3 platform case study.
