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.
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.
In recent years the use of Unmanned Air Vehicles (UAVs) rapidly expanded from mainly military and research applications to a very wide range of applications in civil activities.
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.
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.
From the investigation, the main conclusion is the FES propeller blades destroy the laminar flow and this causes the drag increase.
The topic of the work is to evaluate the energetic cost of non-conventional launch systems dedicated for small satellites.
