Particle image velocimetry was used to characterize wing tip vortex structures as well as quantifying vortex meandering. DSS capabilities in modifying the span-wise wing load and further reduces the wake vortex hazard were carried out. PIV technique was used to measure the wake velocities down-stream of the aircraft half model. Results reveal a noticeable inboard shift of wing loading along with the direct interaction of the spoiler¿s wake and flap tip vortex for the inboard loading cases. Implementation of DSS results in a substantial redistribution of the flap tip vortex circulation. A 44% decrease of the maximum cross-flow velocity was recorded for the case of deployed spoilers. Evaluations of the outboard loading results indicate a limited diffusion experienced by the vortex due to the increased level of turbulence. DSS¿s capabilities as a wake vortex attenuation device reveals, while position of the maximum induced rolling moments is little influenced by the DSS¿s, the maximum induced rolling moment coefficient was reduced to one third.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786139890361\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9786139890361","offer_id":39459829219421,"sku":"9786139890361","price":71.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/e5ada7f0-ef39-4492-8cbd-6e958b00355f.jpg?v=1769149856","url":"https:\/\/shop.autorenwelt.de\/products\/aircraft-wake-vortex-alleviation-an-experimental-approach-von-omer-el-matbagi","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
