Moreover, 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.
Here is an overview of the CEASIOM software, showing aspects of its functionality, process and dataﬂow. Signiﬁcant features are developed and integrated in CEASIOM as modules:
The starting point of CEASIOM: the aircraft builder module.
Allow user to define a parametrized geometry of an aircraft and visualize it.
A replacement of current handbook aerodynamic methods (Digital DATCOM) with new adaptable ﬁdelity modules:
- Steady and unsteady TORNADO vortex-lattice code (VLM) for low-speed aerodynamics and aeroelasticity
- Panel method, such as dwfSolve
- Inviscid Euler solver EDGE for high-speed aerodynamics (based on meshes generated by the external tools SUMO and TetGen)
- CFD tools: RANS (Reynolds Averaged NavierStokes) ﬂow simulator for high ﬁdelity analysis of extreme ﬂight conditions
SDSA (Simulation and Dynamic Stability Analysis) is the SimSAC-developed and license-free S&C software which includes a LQR-based ﬂight control system package, a static and dynamic stability and control analyser and ﬂying-quality assessor. Test ﬂights with six Degrees of Freedom ﬂight simulation, and performance prediction are among the major functionalities of this module.
A designer toolkit for ﬂight control-law formulation, simulation and technical decision support, permitting ﬂight control system design philosophy and architecture to be coupled early in the conceptual design phase
Quasi-analytical structural analysis methods that support aero-elastic problem formulation and solution
