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.
Then, separate Response Surface Model for each output that span the whole design space is generated to investigate the design deeper.Finally, optimal interval values for each input parameters are determined for the wind tunnel test matrix.As a result, number of runs in the test matrix was significantly reduced.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.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.
Tolerance variation in rigid body assemblies results from three sources: size, form and kinematics.
Tolerance analysis software solutions such as CETOL from Sigmetrix, Vis VSA from Siemens PLM and 3DCS from Dassault Systemes are effective for rigid body assemblies and are fully integrated within the major CAD tools such as PTC/CREO, NX and CATIA respectively.
Launch configurations such as ground launch, balloon launch and airborne launch to orbit are considered for different class of satellites and for different orbit altitudes; the analysis is focused on minimizing the booster’s initial mass once set the payload.
When considering a balloon, a trade-off is required in order to evaluate properly the altitude to be reached from the balloon and the mass it has to lift off.
The framework enables the application of robust design at system level and fast cross-functional trade studies on novel engine architectures.
