The "HyGo - Hybrid, Green Upper Stage" project has been kicked off!
The aim of the project is to develop an upper stage for an orbital rocket using innovative and cost-saving technologies. The project is funded by the state of Baden-Württemberg as part of the invest-BW grant. The development of the central part of a rocket requires good coordination of the work areas such as structural development, fluid system, aerodynamics, electronics as well as software development. The foundation for this was laid at the first project meeting.
The participants Astos Solutions GmbH, enGits GmbH, the Institute of Aircraft Systems at the University of Stuttgart and HyImpulse Technologies GmbH stand for "Rocket Technology, Made in Baden-Württemberg". Competence in the "New Space" sector is being built up and jobs created in the region. In addition to overcoming major technical hurdles, this project contributes to the sovereignty of Germany and Europe and secures access to space.
[2022-04-25] An extensively revised and extended version 1.1 of PEET is now available.
The main updates of the tool cover:
[2022-03-28] The release of ASTOS 10 is getting closer. Meanwhile ASTOS 9 has been improved through multiple updates in the last few months from version 9.19 to our newest release 9.22. These releases fixed bugs, added new features and improved existing ones:
[2021-07-27] As the release of ASTOS 10 is getting closer, the current version 9 of ASTOS is receiving its nineteenth update.
In the last releases, new functionalities were added for the application areas Launch Safety Analysis and Closed-Loop Simulation.
Since version 9.15 ASTOS offers the possibility of analyzing the so-called distant focusing overpressure when modeling explosions. You can also analyze the spread of the chemical plume during launch. For a more precise evaluation of the launch risk, the population models can now also be replaced or augmented locally with user-provided data.
Existing models have been expanded for closed-loop applications in which ASTOS is used as a dynamics, kinematics and environment simulator and for modeling actuators and sensors. It is now possible to use the GNSS navigation model, which was originally only developed for the mission analysis, for the detailed modeling of a GNSS receiver taking into account the antenna geometry, visibility of GNSS satellites and the available functionality of the receiver (e.g. number and type of channels).
The integration of ASTOS in automated tool chains is an important topic, especially when it comes to operational applications. It is now possible to start complete batch processes via the command line and reports can now be generated in a text-only format. Latter allows the generation of very customizable data files suitable for import into other tools.
The possibility of coupling ASTOS with other expert tools is an important selling point. Since version 9.17 the properties of flexible bodies can be imported from a NASTRAN file and since version 9.19 ASTOS can be used as a server for an FMI cosimulation, which enables completely new application scenarios.
To name the many other new features here would go beyond the scope. We therefore recommend downloading the latest version of ASTOS and testing its features. The release notes contain a complete list of all new functionalities.
[2020-10-01] Since our last news update several months ago ASTOS has evolved from version 9.7 to 9.13 while new features have been added and existing ones have been improved:
