An Investigation Of Unsteady Vortex Flow Over A Maneuvering Delta Wing, Harry James Kowal
An Investigation Of Unsteady Vortex Flow Over A Maneuvering Delta Wing, Harry James Kowal
Doctoral Dissertations
An investigation of the vortex breakdown phenomenon using flow visualization qualitatively and quantitatively was conducted with a 70° delta wind under conditions of steady and unsteady pitch, roll and combinations of pitch and roll. Testing was carried out in the water tunnel located in the Mechanical Engineering Department of the Royal Military College of Canada, Kingston, Ontario.
Steady state roll experiments with the delta wing pitched at 30° showed that the behavior of vortex breakdown as a function of roll angle could be considered linear over the front half of the delta wing; however, the behavior beyond a certain critical …
