Keynote Lecture: Numerical Studies of Active Flow Control and Aerospace Applications

Abstract: In recent years, a promising approach to the control of wall bounded as well as free shear flows, using synthetic jet (oscillatory jet with zero-net-mass-flux), pulsed jet, and sweeping jet actuators, has received a great deal of attention. A variety of impressive active flow control (AFC) results have been achieved experimentally by many researchers including the vectoring of conventional propulsive jets, modification of aerodynamic characteristics of bluff bodies, control of lift and drag of airfoils, thrust augmentation in ejectors, reduction of skin-friction in a boundary layer flow, enhanced mixing in circular jets, control of external as well as internal flow separation and of cavity oscillations. More recently, attempts have been made to numerically simulate many of these flow fields primarily by employing the Unsteady Reynolds-Averaged Navier Stokes (URANS) equations with a turbulence model and in a limited few cases by Large Eddy Simulation LES) and Direct Numerical Simulation (DNS). In this presentation, the results of simulations of several flow fields dealing with thrust-vectoring control of a propulsive jet, control of separation on a backward facing step, NASA Hump and flap of a multi-element airfoil, control of cavity oscillations, transonic drag reduction of an airfoil, and some aerospace applications such as AFC of high-speed weapon release from a bay, weapons bay acoustic loads reduction and B757 tail for side force augmentation will be described. These simulations have been performed using the URANS equations in conjunction with either a one- or a two-equation turbulence model. The simulations demonstrate the effectiveness of active flow control techniques in flow modification to achieve the desired outcome of drag reduction and separation control in many aerospace applications.

Keynote Lecture: When is an airplane too light?

Abstract: For several decades, airplane designers have constantly designed to remove weight in all aspects of aviation. B 787 and A 350 are examples of innovative material use. At what point are these efforts needing to be stopped as we face the challenge of airplane life usage and reliability? Research will be presented on several ongoing topics and results discussing that the philosophy of weight reduction is counterproductive to the industry.

Keynote Lecture: Synthesis of a passenger aircraft project based on mass sensitivity analysis

Abstract: The synthesis of a new passenger aircraft project is considered, which is carried out based on an existing base aircraft or a previously prepared project. Technical changes in the new project are implementing through partial (initial) changes in the mass of the functional parts of the aircraft. For the analysis, the sensitivity factor of aircraft mass (SFM) to the initial changes are used, obtained analytically using the data of the base project. Fuel efficiency is used as a criterion. Numerical examples are given that show the convenience of applying this approach at the stage of making conceptual decisions.
