Aim of project
The primary aim is achievement of high performance that can be manufactured with low technical and financial risk at an affordable cost. In consort with the application of active systems, flexibility and adaptability of structures and adoption of fl y-by-wire flight control system means the stability and control qualities both in direct and reversionary modes have a cascading impact to aircraft morphology, sizing and overall system architecture.

Expected results
The SIMSAC vision is to meet the challenging demands of fi rst time right calls for a more integrated design approach at the conceptual stage that couples the aerodynamic model to the nonlinear flight — dynamic description and simulates this coupled system at the start of the definition program of the aircraft.
