SUMMARY:On The Use of Supersonic Jet-Curtains for Control of Moments on Tai
 lless Aircraft
DESCRIPTION:Lecturer:Prof. Israel Wygnanski\n Faculty:AME Department \n Ins
 titute:The University of Arizona. Also\, Professor Emeritus Tel Aviv Unive
 rsity\n Location:Classroom 165\, ground floor\, Library\, Aerospace Eng.\n
  Zoom: https://technion.zoom.us/j/97346140543\n Abstract: The purpose of t
 his study was to explore the replacement of conventional moving control su
 rfaces on a typical tailless aircraft model at high subsonic cruise speeds
 . Since the efficacy of sweeping jet actuators was only demonstrated at lo
 w speeds\, the current test considered their potential replacement by Supe
 rsonic Steady Jets (SSJs) of identical nozzle dimensions. It was shown tha
 t even a single SSJ properly located and appropriately oriented may outper
 form an array of actuators whose location and orientation did not take int
 o consideration the changing local flow conditions. The test article chose
 n was the SWIFT model that represents a typical blended wing-body configur
 ation of a tailless aircraft. It was selected because it was tested extens
 ively using Sweeping Jet Actuators (SJAs) that could be used for compariso
 n. When a single supersonic jet designed for Mn=1.5 was used to control th
 e pitch it was able to increase the trimmed lift almost as well as an arra
 y of SJAs while providing a much better yaw control at small accompanying 
 rolling moment. These tests proved that the momentum input is but one of m
 any parameters controlling the flow and they demonstrated the richness of 
 the parameter space involved in AFC design even after the wing design was 
 frozen\n\n\n Details: \n
