Optimal design techniques are not routinely used in the industry when dealing with complex physical phenomena, due to high computing costs. In the CFD field, simplified methods can only provide discrete solutions. The parameterization method described in this paper is based on the differentiation and high-order Taylor-series expansion of the discretized(More)
This paper proposes a multi-model based approach that estimates joint position and collision detection of a lightweight electric actuator dedicated to manipulation tasks. Taking advantage of an optimized back-drivable mechatronic design, the use of proprioceptive measures at the motor level enables the estimation of the unmeasured terminal position of the(More)
A Large-Eddy Simulation (LES) solver together with a Ffowcs-Williams and Hawk-ing (FW-H) solver are coupled with a non-intrusive stochastic collocation method to propagate the geometric uncertainty observed in a rod-airfoil experiment. The LES are performed for several displacements of the rod with respect to its nominal position in the crosswise direction.(More)
This paper extends an existing analytical model of the aeroacoustic response of a rectilinear cascade of flat-plate blades to three-dimensional incident vortical gusts, by providing closed-form expressions for the acoustic field inside the inter-blade channels, as well as for the pressure jump over the blades in subsonic flows. The extended formulation is(More)
Optimal design techniques are not routinely used in the industry when dealing with complex physical phenomena, due to high computing costs. The parameterization method described in this paper is based on the differentiation and high-order Taylor-series expansion of the discretized Reynolds-Averaged Navier-Stokes equations. A flow database containing the(More)
Reliability tests and simulated results on medium power components are discussed in this paper. This study is based on statistical data coming from thermal cycling tests (TCT, air-air test) and thermal shock tests (TST, liquid-liquid test), which are correlated with information coming from failure analysis and compared to results issued from 3D finite(More)
