The v3.0 official release of CEASIOM is available in the download center.

CEASIOM application is a Conceptual Aircraft design tool. It was developed within the frame of the SimSAC (Simulating Aircraft Stability And Control Characteristics for Use in Conceptual Design) Specific Targeted Research Project (STREP) approved for funding by the European Commission 6th Framework Programme on Research, Technological Development and Demonstration. Work began 1 November 2006 and last 3 years (seewww.simsacdesign.eu). The SimSAC project aims at significantly enhancing CEASIOM functionality by introducing software that initially focuses on rapid low fidelity analysis, and as appropriate, resort to higher fidelity numerical simulations. Moreover CEASIOM involve stability and control driven sizing and optimization earlier in the design cycle than is standard practice today.
CEASIOM runs under either Windows or Linux, and its only requires a MATLAB® license.

CEASIOM Objectives

 

Contemporary commercial aircraft conceptual design systems make extensive use of handbook methods based on semi-empirical theory and data. More sophisticated and powerful in-house developed industrial software systems usually alter the widely recognised handbook methods by way of recalibrating the said algorithms with data gleaned from experience and previous design projects. A growing consensus of opinion, however, finds even such recalibrated handbook methods are not reliable enough for treating novel and unconventional designs, and thus, there is a trend towards replacing the methods with computational procedures that calculate the required information from first principles. In order to address this need, the Computerised Environment for Aircraft Synthesis and Integrated Optimisation Methods (CEASIOM) simulation system has been developed. The overiding vision of CEASIOM is procurement of an integrated design and decision making environment where for a given aircraft morphology and local topologies, all necessary predictive computations can take place at some user nominated fidelity during the early conceptual design phase.

Present trends in aircraft design tend towards augmented-stability and expanded flight envelopes call for a more accurate description of the flight-dynamic behaviour of the aircraft in order to properly design the flight control system (FCS), hence the need to increase the knowledge about stability and control (S&C) as early as possible in the aircraft development process in order to be First-time-right with the FCS design architecture.

Up to 80 percent of the lifecycle cost of an aircraft is a direct result of decisions made in the conceptual design phase, and so mistakes must be avoided. A framework that supports state-of-the-art computer-aided concept designs suitable for procuring economically amenable and ecologically friendly designs is seen to be the priority. One aspect that would serve to deliver such important goals is the (architectural) discipline and (technical) subspace of S&C and thus subsequently emphasized into CEASIOM. To this end, it is essential to integrate appropriate software tools when it concerns the instruction of aircraft design and systems integration.
