| Popis: |
The lift reduction potential of fluidic flow control devices is investigated. The devices target unsteady gust load alleviation to achieve a reduction in overall wing weight and fuel consumption. The study focuses on a jet normal to the surface and jet over a Coanda surface installed at the trailing edge. The fluidic actuators are compared to a trailing edge flap for reference using unsteady Reynolds-averaged Navier–Stokes simulations. Unsteady interactions of the airfoil with different gusts are simulated to estimate the required load change and response time of the control devices. To reduce computational costs, a surrogate model based on precomputed aerodynamic polars is developed to estimate gust-induced load changes. The effect of jet temperature for the fluidic actuators and dual blowing for Coanda actuator are studied. |
