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:
1. The Geometry module AcBuilder
The starting point of CEASIOM: the aircraft builder module.
Allow user to define a parametrized geometry of an aircraft and visualize it.
2. The Aerodynamic module AMB-CFD
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
3. The Stability and Control module SDSA
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.
4. The Flight Control System design module FCSDT
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
5. The Aeroelastic module NeoCASS
Quasi-analytical structural analysis methods that support aero-elastic problem formulation and solution
