  • Atkins, M; Dala, L; Tongbeum Kim, T (2014-02)
    The behavior of the flow around two circular cylinders arranged in a side-by-side configuration strongly depends on the transverse center-to-center gap spacing ratio (T/D) where D is the cylinder diameter. Based on the ...
  • Dala, L (IJRAME Aero Team, Hyderabad, 2014-08)
    The aviation industry’s interest towards cavity control methods rose accordingly due to the acoustic attenuation potential of such methods. However cost effective control devices which are also efficient over a wide range ...
  • Beharie, MM; Pedro, JO; Dala, L (Cambridge University Press, 2015)
    This paper presents the design, development and construction of a flight test stand for a quadrotor UAV. As opposed to alternate forms of UAV, the power plant in the case of the quadrotor serves a dual purpose of control ...
  • Dala, L (2015)
    This research is based on the investigation into the dynamic stability associated with seaplanes during take-off. Various forces acting on a hydroplaning hull form have been empirically defined. Such empirical data have ...
  • Tuling, S; Dala, L; Toomer, C (American Institute of Aeronautics and Astronautics, 2013-12)
    A numerical and experimental investigation was performed to study the dominant flow structures in the lee side of a cruciform wing–body configuration at supersonic speeds in the + orientation. The wings or strakes are of ...
  • Meijer, M-C; Dala, L (International Forum on Aeroelasticity and Structural Dynamics (IFASD), 2015-06)
    The basis of linear piston theory in unsteady potential flow is used in this work to develop a quantitative treatment of the validity range of piston theory. In the limit of steady flow, velocity perturbations from Donov’s ...
  • Botha, JDM; Dala, L; Schaber, S (Techno Press, 2015)
    This study aimed to observe the effect of a novel concept (referred to as the flap extension) implemented on the leading edge of the flap of a three element high lift device. The high lift device, consisting of a flap, ...
  • Botha, JDM; Dala, L; Schaber, S (ICAS 2014, 2014-09)
    A novel concept (referred to as the flap extension) is implemented on the leading edge of the flap of a three element high lift device. The concept is optimised using two optimisation approaches based on Genetic Algorithm ...
  • Meijer, M-C; Dala, L (Elsevier, 2015-08)
    An aeroelastic prediction framework in MATLAB with modularity in the quasi-steady aerodynamic methodology is developed. Local piston theory (LPT) is integrated with quasi-steady methods including shock-expansion theory and ...
