Third CEASIOM NEWSLETTER

Public release of CEASIOM v4.0

Dear CEASIOM User,

CEASIOM v4.0 is now available for download on the CEASIOM website. The main changes with the previous release are summarized below.

At present a major development effort is going on to move the geometry handling towards CPACS (Common Parametric Aircraft Configuration Schema). This will facilitate the use of CEASIOM for unconventional aircraft configurations. It is planned to make this new version available in the fall of 2014.

CEASIOM is free, but the development and maintenance depends too a large extend on the work of students and volunteers. To ensure the perpetuity of the software we would like to invite you (or your organization) to consider taking a support option.

Best regards,

The CEASIOM team

CEASIOM v2.0 Public Release

 

Dear CEASIOM users,


The version 2.0 of the CEASIOM application is now publicaly available on the CEASIOM website.
The main enhancements of this version are described on this page.


CEASIOM
is the result of the EU funded project SimSAC (SIMulating Aircraft Stability and Control) which had as objective to build an integrated simulation environment for computing stability and control information with quantifiable uncertainty. CEASIOM integrates into one application the main design disciplines, aerodynamics, structures, and flight dynamics, impacting on the aircraft's performance. It is thus a tri-disciplinary analysis brought to bear on the design of the aero-servoelastic aircraft.

A special session during the AIAA Atmospheric Flight Mechanics Conference, at Toronto (2 - 5 August 2010) will be dedicated to CEASIOM. The session is called "Outcomes from the EU SimSAC project: Simulating Stability and Control" and will take place on Wednesday August 04, 2010 at the Essex Ballroom (Sheraton Centre Toronto).

The program of the session is:

1:00 PM-1:30 PM "Modeling & Simulating Aircraft Stability & Control – SimSAC Project", A. W. Rizzi
1:30 PM-2:00 PM "Flight Manoeuvre Validation of Data Tables Generated Using an Aerodynamic Model Hierarchy", K. J. Badcock; M. Ghoreyshi; A. Da Ronch; D. Vallespin; J. Vos; S. Hitzel
2:00 PM-2:30 PM "From Geometry to CFD Grids - An Automated Approach for Conceptual Design", M. M. Tomac; D. Eller; A. Rizzi; J. Oppelstrup
2:30 PM-3:00 PM "NeoCASS: an integrated tool for structural sizing, aeroelastic analysis and MDO at conceptual design level", S. Ricci; L. Cavagna; L. Travaglini
3:00 PM-3:30 PM "Stability analysis in conceptual design using SDSA tool", T. Goetzendorf-Grabowski; D. Mieszalski; E. Marcinkiewicz
3:30 PM-4:00 PM "Comparison of Conventional and Z-wing VLJ Designs using CEASIOM", T. S. Richardson; C. McFarlane; C. Beaverstock; A. Isikveren
4:00 PM-4:30 PM "Benchmarking the prediction of dynamic derivatives: Wind tunnel tests, validation, acceleration methods", B. Mialon; A. Khrabov; S. Ricci; P. Eliasson; A. Huebner; R. Larsson
4:30 PM-5:00 PM "Virtual Aircraft Design & Control of TransCruiser – a Canard Configuration", A. W. Rizzi; P. Eliasson; C. McFarlane; T. Goetzendorf-Grabowski; J. Vos



CEASIOM is free
. It runs under Windows and Linux. To use CEASIOM one needs to have Matlab installed (Release 2008a or later), including Simulink if one would like to use the Flight Control System Design Toolkit (FCSDT).


The ultimate intention is for the software to be open-source
, but its state of maturity is still not sufficient for its further development to be self-sustaining. Thus this actual release is made with two types of users in mind:
  • The first one is the casual user, for which the Matlab parts of the software consists of p-files and the other modules are compiled code of either C++ or Java. This is done to streamline the installation and to simplify the successful execution of the software for a first-time user.
  • The second release form offers a support option to committed users for a fee, which has as main objective to ensure the perpetuity of the software. Our vision here is to create an active aerospace design-user community around CEASIOM for the free exchange of ideas, concepts, and knowledge on aircraft design, and also its teaching. The community would include not only professional engineers and designers but also the educators of engineers. Under this support option the CEASIOM Matlab m-files along with the C++ and Java source codes are provided. In effect this option opens the further development of CEASIOM to a wider group of committed users/developers than just the original developers and users in the SimSAC Project, thus providing additional momentum to reach a sustainable state for the open-source CEASIOM.


Best regards,

The CEASIOM team

CEASIOM public release by Arthur RIZZI and Jan VOS


CEASIOM: Computerised Environment for Aircraft Synthesis and Integrated Optimisation Methods

 

It is with great pleasure that we announce the public release of the CEASIOM Software which brings the virtual-aircraft approach to multi-disciplinary conceptual design by using physics based modeling.

virtualAircraft

CEASIOM is the result of the EU funded project SimSAC (SIMulating Aircraft Stability and Control) which had as objective to build an integrated simulation environment for computing stability and control information with quantifiable uncertainty. Now at the end of the SimSAC project the software, although still rapidly maturing, is ready for its first release to interested third parties. CEASIOM integrates into one application the main design disciplines, aerodynamics, structures, and flight dynamics, impacting on the aircraft's performance. It is thus a tri-disciplinary analysis brought to bear on the design of the aero-servoelastic aircraft.

ceasiomModules

CEASIOM is free and can be downloaded from the CEASIOM web site (www.ceasiom.com). It runs under Windows and Linux. To use CEASIOM one needs to have Matlab installed (Release 2008a or later), including Simulink if one would like to use the Flight Control System Design Toolkit (FCSDT).

The ultimate intention is for the software to be open-source
, but its state of maturity is still not sufficient for its further development to be self-sustaining. Thus this initial Release is made with two types of users in mind:

- The first one is the casual user, for which the Matlab parts of the software consists of p-files and the other modules are compiled code of either C++ or Java. This is done to streamline the installation and to simplify the successful execution of the software for a first-time user.

- The second release form offers a support option to committed users for a fee, which has as main objective to ensure the perpetuity of the software. Our vision here is to create an active aerospace design-user community around CEASIOM for the free exchange of ideas, concepts, and knowledge on aircraft design, and also its teaching. The community would include not only professional engineers and designers but also the educators of engineers. We believe that the virtual-aircraft paradigm is becoming more and more central to the work of aerospace engineers, and that this paradigm must enter more fully into the engineering education curriculum. CEASIOM, we believe, is an ideal means for introducing physics-based multi-disciplinary design into the curriculum. Already at KTH CEASIOM is the tool that students are using in one of their aircraft design projects. The CEASIOM user community could become a forum for exchange of ideas and experiences for enriching this approach to multi-disciplinary aircraft design, and all of you are invited to participate. Under this support option the CEASIOM Matlab m-files along with the C++ and Java source codes are provided. In effect this option opens the further development of CEASIOM to a wider group of committed users/developers than just the original developers and users in the SimSAC Project, thus providing additional momentum to reach a sustainable state for the open-source CEASIOM.

As interest in CEASIOM grows, we intend to organize special sessions at conferences (for example AIAA, CEAS, ICAS, EWADE, etc) where people can exchange their experiences, ideas, and new concepts obtained by using CEASIOM. However, to implement this vision we need a sufficient number who are willing to take the support option.

You will find attached a poster dedicated to CEASIOM. Further details and documentations are available on the website: www.ceasiom.com

We hope that you will like CEASIOM enough to join us, either initially as a casual user or preferably a more committed user.
