Study On The Software Of Configuration Analysis Of Liquid Propellant Space Propulsion Systems

What the study of the software of configuration analysis of liquid propellant space propulsion systems solved is how to develop the software of configuration analysis of liquid propellant space propulsion systems using scientific software model based on the characteristics of liquid propellant space propulsion systems in order to improve the performance and reduce the mass etc. It's important that can save fees and improve corporation's ability of participating competition.First, several models needed in configuration analysis of liquid propellant space propulsion systems are presented in this paper. Classify all components into the components of gas routes and the comoponents of liquid routes, then classify the components of gas routes and the components of liquid routes. Different equations to corresponding components are presented by analysing and transformating the general equations of fluid routes, then static characteristics mathematical model of liquid propellant space propulsion system is presented. Based on the data of static characteristics calculation, mass model of thruster, propellant, propellant tank, gas, gas bottle, pipe and valve is presented using both the method of statistical regression and the method of stress analysis, then corresponding mass model is presented. Based on the characteristics of liquid propellant space propulsion systems, analyse the five phases(concept and definition, design and improvement, manufactureing and arrangement, operation and maintenance, disposal) in which life cycle cost of liquid propellant space propulsion systems is cost separately, then discompsed structure of life cycle cost and model of life cycle cost are presented. The method of getting data from accounting system is easy, rapid,correct, so discompose the cost using the principals of accouting when building the discomposed structure of life cycle cost. The discomposed structure of life cycle cost have a good interface to accounting system and it is easy to use the data of accounting system. By the way, optimization model and static characteristics simulation model is presented and thermodynamic calculation is done in this paper.Second, the concept of unified modeling language is describled, and its "4+1" views(Use Case View. Logical View, Implementation View, Process View, Deployment View) are describled based on the characteristics of liquid propellant space propulsion systems. Software process model, the concept of iteration and increment, the concept of software development based on risks , Sysnerty software process model are describled; Software model of the study of the software of configuration analysis of liquid propellant space propulsion systems is presented in this paper using Unified Modeling Language and Synergy software process model.
