CINDA-SV

CINDA-SV stands for "Computational Integrated Design and Analysis for Space Vehicles. The project is realized together with ESA/ESTEC.

The goal of the project is the design and creation of a software environment integrating all the aspects of the development phase of a space vehicle. In other words, a specialized problem-solving environment (PSE) that acts as a "virtual space vehicle" is to be developed. (In our terminology, space vehicles are spacecrafts with an integrated propulsion system.)

Designing a space vehicle is a complex task as many different physical disciplines are involved. This means that several engineers, often from many different places, collaborate during the design phase of a space vehicle. Hence, distributed working, involving heterogeneous environments and large distances, has to be facilitated by the environment.

This complexity also means that multidisciplinary design and analysis have to be addressed. Thus, coupling of several simulations, such as fluid dynamics, structural mechanics, and chemistry, is a central topic. As unidisciplinary simulation tools have reached a reasonably mature state, they shall be reused as far as possible. Thus, we aim at providing a generic infrastructure for coupling of arbitrary unidisciplinary simulations in a modular system. Hence, loose coupling is the preferred method as it allows the use of unidisciplinary simulation tools as building blocks of a multidisciplinary simulation. Although multidiscplinary optimization (MDO) is not a topic of this project, its requirements on such an integrated system shall be considered.

Engineers shall be assisted by the CINDA-SV environment as far as possible. Thus, easy access to the huge amounts of data involved during the design phase of space vehicles as well as to existing knowledge is important. Tight integration of a data base system into the CINDA-SV environment is the consequence. The usefulnes of knowledge-based systems has to be evaluated, too.

The CINDA-SV system shall reach wide adoptance across ESA partners in all industries. Therefore, the CINDA-SV environment shall be flexible enough to allow easy integration of all kinds of tools, including proprietary ones. Portability and user-friendliness are equally important. In this context, interface standards are an important aspect. Besides existing standards such as CORBA, the usefulness of GRID technologies for integration environments has to be evaluated.

In order to minimize work duplication, similiar on-going projects, especially those at ESA and those funded by the EC as well as commercial ones, have to be reviewed. If reasonable, the CINDA-SV concepts shall be general enough so that they can be applied to branches other than space vehicles.

Currently, existing systems are evaluated and CINDA-SV is being designed.

The project CINDA-SV is now finished, its duration was from February to December 2003.
