Experimental Characterization Of Additively Manufactured Multi-Feather Wingtip Devices, Patricio Garzon
Experimental Characterization Of Additively Manufactured Multi-Feather Wingtip Devices, Patricio Garzon
Doctoral Dissertations and Master's Theses
Soaring birds have evolved to fly for long periods of time without flapping their wings. Inspired by the flight of these birds, the proposed thesis presents an experimental investigation focused on wingtip devices designed based on biomimicry. The overarching engineering objective was to reduce the induced drag as a means to improve the fuel efficiency via these experimental wingtips. An associated secondary objective was to establish a method for manufacturing complex structures suitable for wing tunnel testing. A manufacturing technique that involved using composite weaves to reinforce additively manufactured structures was developed. This technique has the potential to reduce manufacturing …
Influence Of Wing Planform Shape On The Effectiveness Of A Fixed-Slot, Yuan Zhao
Influence Of Wing Planform Shape On The Effectiveness Of A Fixed-Slot, Yuan Zhao
Doctoral Dissertations and Master's Theses
This thesis report explores the effect of the Clark-Y wing geometry on lift and drag to use as a reference during aircraft design stage. The different characteristics investigated are fixed slot span, taper ratio, washout, and sweep angle. Plain wings, half slotted wings, and fully slotted wings were built in CATIA with an aspect ratio of 6 and different taper ratio, washout, and sweep angles. Using the CATIA models to generate the 3-D grids in Pointwise. All the simulations were tested in Ansys-Fluent under sea-level conditions with a Reynold number of 609000. The relationships between the aerodynamic characteristics and the …
