Available in PDF, EPUB and Kindle. Book excerpt: Satellite development worldwide has significantly changed within the last decade and has been accelerated and optimized by modern simulation tools. The classic method of developing and testing several models of a satellite and its subsystems with the aim to build a pre-flight and finally a flight model is being replaced more and more by a considerably faster and more inexpensive method. The new approach no longer includes functional test models on entire spacecraft level but a system simulation. Thus overall project runtimes can be shortened. But also significantly more complex systems can be managed and success oriented tests on integration and software level can be realized before the launch. Applying modern simulation infrastructures already during spacecraft development phase, enables the consistent functionality checking of all systems both in detail and concerning their interaction. Furthermore, they enable checks of the system's proper functionality, their reliability and safety / redundancy. But also analysis regarding aging and lifetime issues can be performed by simulation. Project-related simulations of operational scenarios, for example with remote sensing satellites, and the checking of different operational modes are of similar importance. On the whole, risk is reduced significantly and the satellite can be produced in a considerably more cost efficient way, with higher quality and in shorter periods of time. Therefore "Simulating Spacecraft Systems" - the title of the present book - is an important domain of modern system engineering, which meanwhile has successfully established a position in many other sectors of industry and research, too.

Download or read book Bayesian based Simulation Model Validation for Spacecraft Thermal Systems written by Kevin Dale Stout and published by . This book was released on 2015 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last several decades of space flight, spacecraft thermal system modeling software has advanced significantly, but the model validation process, in general, has changed very little. Although most thermal systems are successful, there is evidence of some model inaccuracy and thermal system overdesign due to the conservatism of the current (i.e., conventional) validation process. A significant improvement to the model validation process can result in the reduction of resource-related (e.g., mass, volume, or power) or process-related (e.g., design, verification and validation, operations) mission costs. This thesis proposes a Bayesian-based Model Validation (BMV) methodology as a tailored framework that combines the state of the art model validation methods within the fields of Uncertainty Quantification (UQ) and Design of Experiments (DOE) to improve the thermal model validation process. In BMV, model uncertainties are rigorously quantified upstream of the model and propagated through the model to determine their influence on the quantities of interest (QoIs). Critical system parameters that most significantly create variance in the QoIs are identified. Optimal parameter inference experiments, implemented prior to system-level model validation experiments, target the critical system parameters to learn more about the system earlier in the project lifecycle. Finally, given experimental data, Bayesian inference methods are utilized to systematically update the model. BMV is model-based and takes advantages of system-specific information. Furthermore, the validation process is iterative, and the outcome of each step informs the validation procedures for the subsequent step. The first of two case studies is a passive spacecraft radiator. The radiator is a simple, notional system, and the primary objective of the case study is to demonstrate the basic aspects of the BMV methodology. Synthetic data are generated for the radiator case study. It is shown through BMV that analyses, test conditions, and decision-making during the validation process can differ from a conventional validation approach because more information is available to the engineer. By identifying and reducing uncertainty in the critical system parameter (the radiator's emissivity) early in the lifecycle, the case study shows that the final radiator's mass and volume could be lower than a conventional approach. The second case study of the thesis is the REgolith X-ray Imaging Spectrometer (REXIS) Solar X-ray monitor (SXM). In the SXM case study, the driving thermal system parameter, the maximum interface temperature with the spacecraft, TO-REx, is relaxed to determine the maximum value to which TO-REx could have been set using BMV. Of the three operational SXM requirements, uncertainty analysis reveals that the detector temperature is the driving QoL. Global sensitivity analysis reveals that the uncertainty in a conductance parameter most significantly creates uncertainty in the detector temperature. Both an optimized parameter inference experiment to reduce the conductance's uncertainty and a model validation experiment are implemented in a thermal vacuum chamber. A model calibration procedure, utilizing a Markov Chain Monte Carlo (MCMC) method, is used to systematically update the model parameters. Finally, once the model parameters are updated, a model discrepancy term is added to the model output to account for the persisting model inadequacy. The validated SXM model is used predictively to show that the maximum value of TO-REx could have been set up to 10 °C warmer than the original upper limit. The primary innovation of BMV is the improvement to the thermal model validation process. BMV is a rigorous, systematic validation methodology that can identify and reduce important model uncertainties in a spacecraft thermal system. BMV can increase knowledge of the system early in the project lifecycle when important design- decisions are made by focusing research and testing efforts on critical system sensitivities. Because model uncertainties are better understood, margin, if needed, can be applied in a system-specific manner to address particular system or environmental uncertainties.
