Control of Flow Structure on a Semi-Circular Planform Wing
Active flow control is used to modify the lift, drag and pitching moments on a semicircular wing with aspect ratio, AR = 2, and chord Reynolds number is 68,000. The wing is mounted on a pitch/plunge sting mechanism that responds to the instantaneous loads and moments acting on the wing. The leading edge of the airfoil contains 16 spatially localized actuators that can be independently controlle...
متن کاملControl of a Semi-Circular Planform Wing in a "Gusting" Unsteady Freestream Flow: I-Experimental Issues
Active flow control is used to modify the lift, drag and pitching moments on a semicircular wing during “gusting” flow conditions. A longitudinal oscillating flow component has an amplitude of 10 percent of the freestream speed and a frequency giving k = 0.048 (f =0.2 Hz). The aspect ratio of the wing is AR = 2.54, and the chord Reynolds number of the wing is 70,600. Pulsed-blowing flow control...
متن کاملWing Planform Optimization via an Adjoint Method
This dissertation focuses on the problem of wing planform optimization for transonic aircraft based on flow simulation using Computational Fluid Dynamics(CFD) combined with an adjoint-gradient based numerical optimization procedure. The adjoint method, traditionally used for wing section design has been extended to cover planform variations and to compute the sensitivities of the structural wei...
متن کاملControl of a Semi-Circular Planform Wing in a “Gusting” Unsteady Free stream Flow II: Modeling and Feedback Design
The research outlined in our two parts abstract is carried as part of a MURI research program whose purpose is to use feedback flow control to extend the range of aspect ratios, Reynolds numbers and angles of attack (AOA) for which high lift and high maneuverability can be achieved. Our work is motivated by the remarkable aerodynamic performance of bio-fliers wings, enabled by their stable lead...
متن کاملAerodynamic Hovering Performance of Rigid and Flexible Wing Planform Shapes
Wing geometric parameters govern the aerodynamic performance of insects and micro aerial vehicles. Previous studies of wing shapes have been limited to rigid wings. The aerodynamic hovering performance of rigid and flexible wing shapes for aspect ratio AR = 1.5 is evaluated computationally at the Reynolds number (Re) of 400. The three-dimensional viscous incompressible Navier-Stokes equations a...
