    Numerical methods have progressed, a lot however there are still phenomena (accurate buffeting assessment in all flying conditions for instance), or analysis of totally new aircraft configurations where wind tunnels can not be replaced. The experimental methods already developed, and the ONERA Wind Tunnel Division's ongoing quest for improved testing techniques, are key issues to provide the expected support
  • 2 Gust effect control: a European first at ONERA

    The effect of gust fields on the aerodynamic and aeroelastic behaviour of the model was analysed and the experimental data was delivered to ONERA's main partners (Airbus and Dassault Aviation) for the validation of their numerical methods. Control results for Mach= 0 3 and 0 73 on accelerometer responses for a broadband gust disturbance
  • 3 First European OpenMDAO workshop

    It enables you to decompose your models, making them easier to build and maintain, while still solving them in a tightly coupled manner with efficient parallel numerical methods. Program
  • 4 Transonic Flow around Fuselage and Wings

    The improvements of numerical methods and turbulence models will increase precision in the simulations. Share
  • 5 Onera and Cetim Make a Breakthrough in the Production of Composite Parts

    Thus, Onera designed the wishbone suspension using its numerical methods that were developed for aerospace, according to the requirements of a set of automotive specifications provided by PSA Peugeot Citroën. Cetim developed a high rate production line, consistent with automobile production requirements, relying on Compose, which made an innovating mold for the part
  • 6 New tools for numerical simulations

    CAA consists in the study, using numerical methods, of the noise radiation of an aero-acoustic source, or sound wave propagation in a flow. Euler Equations
  • 7 More realistic virtual engines

    Hence the need to develop" unsteady" physical models and numerical methods that can be used to calculate the results of these models. Dispersed phase (fuel droplets) in green
