An experimental investigation of interacting wing-tip vortex pairs
The interactions of trailing vortex pairs shed from the tips of two rectangular wings have been studied through helium bubble flow visualizations and extensive hot wire velocity measurements made between 10 and 30 chord lengths downstream. The wings were placed tip to tip at equal and opposite …

The Effect of Butterfly Inspired Scales on Wing Tip Vortex Development
… focuses on the scale patterning found on the wing tips, where scales are three times the size of the traditional scales that coat the wing surface. It was hypothesized that the long wing tip scales of the Monarch butterfly act to modify the growth and development of the tip vortex in order to …

An Investigation of Avian Wing Tip Vortex Generation Using a Biomimetic Approach
… has been conducted to develop a process allowing the creation of biologically accurate aerodynamic test models mimicking the slotted primary feather geometry of the Brown Pelican (<em>Pelecanus occidentalis</em>). Preserved examples of both a full Brown Pelican wing and a single primary …

Numerical Wing/Store Interaction Analysis of a Parametric F16 Wing
… to examine fluid-structure interaction of a wing/pylon/store system has been developed. The aeroelastic equation of motion of the complete system is solved iteratively in the time domain using a two-entity numerical code comprised of ABAQUS/Standard and the Unsteady-Vortex-Lattice Method. …

Experimental and Numerical Investigations of the Aerodynamics of Flexible Inflatable Wings
… some of the benefits offered by inflatable wings for use in tethered kite-like systems towards the goal of designing a High Altitude Aerial Platform (HAAP). Uses of such a system include Airborne Wind Energy Systems (AWES), among others. The key bene- fit offered by such wings is their …

Effects of Turbulence Modeling on RANS Simulations of Tip Vortices
… vortical flows. The simulation of aerodynamic wing-tip vortices is used as a test bed. The primary configuration is flow over an isolated finite wing with aspect ratio, , and Reynolds number, . Tip-vortex velocity profiles, vortex core and wake turbulence levels, and Reynolds stresses are …

Understanding the Structure of Wing Tip Vortices of Bio-Inspired Winglets
<p>Bio-inspired wing tip devices were investigated with the goal of improving the fuel efficiency of subsonic aircraft. Particularly, the structure of a bio-inspired winglet design based on bird feathers were tested in a low-speed wind tunnel. Particle image velocimetry (PIV), was used to study the …
