The turbulence structure of trailing vortex wakes
… In the second part, flow visualizations of the wake behind a delta wing model were made for a range of Reynolds numbers and lift coefficients. These visualizations reveal the near-instantaneous turbulence structure of the wing wake which is dominated by a vortex pair and a connecting "braid" …

Wing Deflection Analysis of 3D Printed Wind Tunnel Models
… scale model of the NASA CRM was produced, whose wings were manufacturing using a Finite Deposition Modeling 3D printer. Experimental data was compared to numerical simulations to determine percent difference in wake distribution and wingtip deflection for multiple configurations.</p> <p>Numerical …

The effect of turboprop propulsion on the aerodynamic benefits of formation flight
… to model the progression and interaction of the wing and turboprop trailing wakes. Within this programme, an initial prescribed wake for the turboprop engines was discretised by shed helicoidal vortex filaments generated by the use of an amalgamation of the propeller theory of Goldstein and …

The structure of a trailing vortex wake
Experiments have been performed in the spiral wake that surrounds the vortex shed from the tip of a rectangular NACA 0012 half wing. Both single-point and simultaneous two-point hot-wire measurements were made ten chord lengths downstream of the wing at a Reynolds number of 320,000. The structure …

Modeling and validation of a subscale aerobatic aircraft configuration in spin
… approach is taken that involves the following components: flight testing, the development of a new analytical model for calculating the forces on a stalled spinning wing, and validation of that model through wind tunnel tests. Significantly, these results are combined to form a new code, …
