SUMMARY:Understanding Aerodynamic Principles toward Air Vehicle Design and 
 Analysis
DESCRIPTION:Lecturer:Dr. Camli Badrya\n Faculty:Institute of Fluid Mechanic
 s\n Institute:University of Braunschweig\n Location:https://technion.zoom.
 us/j/94912022701\n Zoom: \n Abstract: \n Details: \n The design and develo
 pment of high-performance\, efficient\, and sustainable aircraft for a wid
 e range of applications requires a fundamental understanding of the underl
 ying aerodynamic principles. For instance\, the aerodynamic phenomena that
  govern micro air vehicles (MAVs) flight are drastically different from th
 at of a fixed-wing aircraft flying at transonic speeds. While high fidelit
 y CFD and experimental methods can help unravel the physics\, for design p
 urposes\, robust and efficient tools are required. The seminar would focus
  on the foundational studies we conducted to understand the aerodynamic pr
 inciples related to two applications operating in different flight regimes
  and how the knowledge gained is integrated into aircraft design.\n\n\n 	 
 Large gust encounters for UAM: Wing response to large transverse gusts has
  become an active area of research\, driven by the demand for both manned 
 and unmanned air vehicles including urban air mobility (UAM) applications.
  Because of their relatively small size\, these vehicles are more likely t
 o respond adversely to large gust disturbances during flight. They operate
  at relatively lower Reynolds numbers where the effects of viscosity could
  be significant\, and control models and design optimization rely strongly
  on how accurately the aerodynamic forces during wing–gust interactions 
 can be predicted. The key research questions we are trying to answer are: 
 Can the classical unsteady theory (mainly Kussner-based) capture the wing 
 aero response during larger traverse gust encounters? And how can wing-gus
 t interaction be modeled efficiently?\n 	 LFC for green aviation: Future e
 nergy-efficient aircraft require a drastic reduction in drag. The flow on 
 a state-of-the-art commercial airplane wing is turbulent. The laminar flow
  control (LFC) technique offers large potential for drag reduction. LFC is
  an active boundary-layer control\, usually by utilizing wall suction to r
 etain laminar flow and delay transition from laminar-to-turbulent flow. LF
 C technique can be employed on the lifting and non-lifting surfaces (i.e.\
 , wing\, fin\, and fuselage) resulting in reduced skin-friction drag. Our 
 current research focuses on optimizing a wing for LFC application and inve
 stigating how to integrate the LFC technology into the overall aircraft de
 sign.\n
