Responsibilities

IM Modeling & Systems Analysis Duties

Implement necessary changes to convert the standard STOP structural model to support composite moisture desorption analysis for both steady state and transient cases; the latter includes coordination with thermal modelers/analysts to enable temperature mapping onto the structural model and implementation of temperature variability for key variables

Perform steady state and transient moisture desorption analysis for flight and TVAC test cases with primary responsibility for recovering distortions and coordinating with opto-mechanical and optical analysts to recover optical performance metrics

Perform Monte Carlo analysis as necessary to validate Model Uncertainty Factors (MUF) based on variability of key model properties Invar Growth Analysis Implement necessary changes to convert the standard STOP structural model to support Invar growth analysis

Perform steady state Invar growth analysis for flight cases with primary responsibility for recovering distortions and coordinating with opto-mechanical and optical analysts to recover optical performance metrics

Perform Monte Carlo analysis as necessary to validate Model Uncertainty Factors (MUF) based on variability of key model properties Gravity Release Analysis Implement necessary changes to convert the standard STOP structural model to support gravity release analysis

Perform gravity release analysis with primary responsibility for recovering distortions and coordinating with opto-mechanical and optical analysts to recover optical performance metrics

Perform Monte Carlo analysis as necessary to validate Model Uncertainty Factors (MUF) based on variability of key model properties
