    • Conceptual Design of Boom Mounted Inverted V-Tail in the Searcher MK II UAV 

      Khadka, Sushil; Abeygoonewardene, JI; Liyanage, NP (2020)
      Abstract: Long endurance surveillance drones are preferred in both military and meteorological applications. Designers aim to enhance vehicle aerodynamics in view of increasing endurance by introducing methods of drag ...

    • Estimation of Lift Hysteresis of an Airfoil in low speed flow 

      Jayathilake, WARD; Abeygoonewardene, JI (2022-09)
      Abstract: A phenomenon called hysteresis leads to a difference in separation and reattachment angles of an airfoil at angles of attack near and above stall. This an airfoil than expected for a given angle ...

    • Estimation of Lift Hysteresis of an Airfoil in Low Speed Flow 

      Jayathilake, WARD; Abeygoonewardene, JI (2022-09-29)
      A phenomenon called hysteresis leads to a difference in separation and reattachment angles of an airfoil at angles of attack near and above stall. This occurs when there is a difference in the lift distribution of an ...
