Computational Fluid Dynamics: A Design Tool for Aircraft Industrieslems which are anticipated in flight can be solved during design stage itself by making use of modern technology, that is Computational Fluid Dynamics (CFD). This chapter gives an overview of what has been achieved in aircraft design using CFD and what are the future challenges which are required to

Design and Field Trials of a Payload Recovery Device for Tethered Aerostats breaks. The recovery of payload is accomplished in three stages, viz., tether breakage detection, signal transmission, and device activation. The envelope of aerostat is deflated by deploying a mechanism that results in a small circular hole on its top. As the LTA gas in the envelope escapes, the b

Design of an Effective Subsonic Wing Cross-Section Using Viscous-Inviscid Interactive Methodsubsonic incompressible flow regime at four degree angle of attack. An iterative inverse design method is followed to obtain airfoil for desired lift to drag ratio. Differential evolutionary (DE) optimization technique with micro population and elitism is employed and lift to drag ratio has been inc

Computational Study of Various Longitudinal Fin Profiles modeled in CATIA and the further simulations were carried out in ANSYS Fluent. The present research is focused on the performance parameters of fins such as temperature distribution, fin effectiveness, and fin efficiency for different fin geometries. The values obtained from the CFD software have b

A Synchronous Wound Excitation Transverse Flux Machine with Solid Rotoreel rotor allows functioning at high speeds and in high ambient temperatures. Following the presentation of the machine, a simple analytical model confirms the concept. A finite element analysis allows a refined model and tests on a prototype motor validate the concept in the end.
