Franks\n    --- General refactor\n\n -- v6.1 D. Gibbons (dug20)\n    --- Now stores and exports additional data that is needed for a\n        more complex moment of inertia model in the 6DOF simulator.\n    --- Additional properties added to motor_out.csv:\n        - Vapour Density\n        - Vapour Mass\n        - Liquid Density\n        - Liquid Mass\n        - Solid Fuel Mass\n        - Solid Fuel Density\n        - Solid Fuel Outer Diameter\n        - Solid Fuel Length\n\n\nInstructions:\nModify inputs at top of motor_sim.py and run using python 3.\nProgram outputs file motor_out.csv (used as an input to trajectory_sim.py).\n\n\nOther dependencies: numpy, scipy, matplotlib\n\nFiles:\n motor_sim.py         simulation program for motor\n motor_out.csv        motor performance output file generated by motor_sim.py\n hybrid.rasp          output .rasp file for RAS aero*\n trajectory_sim.py    simuluation program for rocket trajectory\n hybrid_functions.py  contains functions governing motor behaviour\n                       and material properties\n\nAdditional input data:\n atmosphere_data.csv          1976 standard atmosphere\n drag_coefficient_data.csv    drag coefficient to mach data (RAS Aero)\n L_Nitrous_S_HDPE.propep      propep frozen and shifting outputs for\n                               a range of pressures and O/F ratios\n\n\n*Note that a perennial problem with RASP data is the rate of decrease of mass\nis always assumed to be proportional to thrust, which is invalid as a nitrous\nhybrid's ISP changes with time. Hence further use of this file introduces error\nfrom this approximation.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcuspaceflight%2Fnovus","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcuspaceflight%2Fnovus","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcuspaceflight%2Fnovus/lists"}
