Abstract

Provides the method of describing the impact  micrometeoroid and orbital debris (MMOD)  on the Micrometeoroids and Debris Protection System (MDPS)  for inflatable modules for lunar orbital application. The fabric materials  used to create inflatable modules  are proving they can perform just as well as more rigid structures in space, but the impact physics is different.
Flexibility  of  the  materials  allows  the  structure  to  be  packaged  into  a  small  volume  for  launch,  advances  in  materials  and  load  path  concepts  are  needed  to  reduce  the  weight  of  these  flexible  material  systems.    Advanced  flexible  polymers  and  high  strength  fiber  reinforcement  should  enable  lower  mass  structures.  
The method for calculating the strength of an MDPS inflatable module consists of two stages. At the first stage, the impact  MMOD is numerically modeled on the MDPS of the inflatable module. In the second stage, the analytical calculations of the stress-strain state of the containment loaded localized pulse load
Statistic Optimization for MDPS. The  development  of  method of describing the impact MMOD linked  with  this  type  of shields  will lead  to  an  improvement  in  their  design,  in  terms  of  mass,  efficiency  and costs.
