The framework enables the application of robust design at system level and fast cross-functional trade studies on novel engine architectures.The paper demonstrates a more efficient integration of structural and thermal analysis simulation capabilities.A link between CAD geometry and FEA tools is established to drive design via analysis and enable multi-disciplinary design optimisation.
This paper will present techniques that perform tolerance analysis on assemblies with flexible components within the CAD and CAE environments.
In this study, wind tunnel test matrix of a newly developed Air-to-Ground missile is designed utilizing the Design of Experiment method based on Computational Fluid Dynamics simulations for various combinations of input parameters that are angle of attack, side-slip angle, Mach number, and the tail fin deflections.
Aim of this job is the design optimization of a MLG shock absorber hydraulic system in order to guarantee the compliance with the customer performance requirements.
The case study, developed through a close cooperation between Magnaghi Aeronautica and Engin Soft, allowed to evaluate positively the capacities of the software mode FRONTIER.
The impact area on the ground is evaluated both in a deterministic way – which depends on vehicle dimensions and kinetic energy – and in a statistical way – where uncertainties of the navigation parameters (position and velocity) are introduced.
The impact areas are then related to vehicle failure rate and to a real population density map, resulting in a reliable risk evaluation.
Once the relation between the nominal vehicle trajectory and corresponding risk level is defined, a suitable multi-objective optimization process is developed, searching for the optimum solutions that minimize path length and risk, the latter being constrained below a prescribed maximum admissible value.
Eventually, the candidate optimum paths are visualized and evaluated within a virtual console, developed and addressed in terms of a cloud architecture.
Therefore, determination and mitigation of the risk they can represent to people in the event of a ground impact is a key point for the development of UAV regulations in the civil airspace.
