An integrated simulation of an advanced life support system for intelligent control research.
ALSSAT has been developed for use in the sizing and analysis of Environmental Control and Life Support Systems (ECLSS) for spacecraft and habitats. The purpose of this tool is to perform life support system trade studies and analysis. ALSSAT aids in the creation of conceptual designs for advanced systems using physiochemical and biological processes in either open-loop systems or closed-loop systems that recycle air and water as well as process human waste products. The regenerative life support processes can be used as a means to decrease the amount of consumable re-supply required for a range of missions including in-space transit vehicles or habitats, and surface habitats on the moon or Mars.
The Agile ISRU Demo Plant Sizing Tool will provide a rough parametric estimate of ISRU plant mass and power requirements based on fitting data to a heritage curve. NEO, Phobos, Lunar Surface, and Martian Surface are included at a notional level within this system that allows architecture designers to roughly scale ISRU plants before talking to specialists.
This tool sizes short duration human habitats for short missions less than 20 days based on identified human operations requirements.
Mars In-Situ Resource Utilization (ISRU) Propellant Production Discrete Event Simulation (DES)- MIPP-DMIPP-D is a Simio based Discrete Event Simulation modeling Mars surface propellant production. The focus is on the actual chemical plant and processes, including incoming and outgoing materials, associated with the production of rocket fuel on Mars. The fuel will be for the Mars Ascent Vehicle used to carry humans into space from the surface of Mars. The Simulation utilizes NASA ground rules and assumptions as well as data from prototype chemical plants, NASA experts and literature.
The Thermal Insulation System Analysis Tool has been updated with more test data from the Cryogenics Test Laboratory and has been converted to Fortran 95 to allow for easier distribution.
The Toolbox for the Modeling and Analysis of Thermodynamic Systems (T-MATS) is a Simulink toolbox intended for use in the modeling and simulation of thermodynamic systems and their controls. T-MATS contains generic thermodynamic and controls components that may be combined with a variable input iterative solver and optimization algorithm to create complex systems to meet the needs of a developer.
The CARNOT toolbox contains models for thermodynamics/energy engineering with focus on HVAC systems.
A model for simulating the indoor climate and energy use of greenhouses with supplemental lighting.
The ANFIS based MPPT controller has been designed for generating the maximum power from different renewable energy sources [PV, wind, and fuel cell].
OLTARIS, the On-Line Tool for the Assessment of Radiation in Space. OLTARIS is an integrated tool set utilizing HZETRN (High Charge and Energy Transport). These tools are intended to help scientists and engineers study the effects of space radiation on shielding materials, electronics, and biological systems.
Ansys Student offers free access to our Ansys Workbench-based bundle. This bundle includes Ansys Mechanical, Ansys CFD, Ansys Autodyn, Ansys SpaceClaim and Ansys DesignXplorer.
FreeDyn is a free simulation software designed for solving challenging scientific and industrial problems in multibody dynamics with systems consisting of flexible bodies. It serves as an easy-to-use software tool for modeling mechanical systems including rigid as well as flexible bodies connected by joints and constraints. The geometry can either be imported from a CAD system or designed in FreeDyn from scratch. FreeDyn solves the equations for dynamic simulations and offers an advanced visualization of solutions by graphs, plots and animations.
Below is a list of software tools we have found useful in the development of small spacecraft missions.This list is restricted to publicly available software from NASA or the Open Source community.
