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.
A link between CAD geometry and FEA tools is established to drive design via analysis and enable multi-disciplinary design optimisation.
The implementation of the framework has been driven by aero engine project needs and priorities, following an agile software development approach.
The present work, conceived and promoted within the Apulian Aerospace Technological Cluster (DTA) and developed into the co-funded project “TAKE-OFF - Test and Knowledge‐based Environment for Operations, Flight and Facility” (in the “Cluster Tecnologici Regionali - Smart Puglia 2020, Regione Puglia” frame program) introduces a path planning methodology where the risk related to UAV operation is reduced by estimating the probability of hitting a person on the ground, assuming a map of the population density in the area interested by the flight is available.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.By using CFD tools, a comparison for bare fuselage and FES device installed is done.For the current study two speeds are investigated: 120 km/h (near at the maximum efficiency) and 180 km/h (usual cross country straight speed), with the cabin ventilation closed.
Tolerance variation in rigid body assemblies results from three sources: size, form and kinematics.
