The standard box car design has a large drag and wake area which results in high fuel consumption. One way to reduce drag and wake area is to modify the box car design. Modifications were made by adding an aerokit spoiler and deflector to a standard box c... see more

The experimental data for a Cbladed soft-inplane hingeless main rotor is used to validate a comprehensive aeroelastic analysis. A finite element model has been developed for the rotorblade which predicts rotating frequencies quite well, across a range of ... see more

Using the effect of wingtip vortex from a leading aircraft, the formation flight of unmanned combataerial vehicles (UCAVs) can accomplish various tasks with much more efficiency. Combined withthe sliding mesh technique, this paper investigates a computati... see more

The aerodynamics of contra-rotating propellers is a complex three-dimensional problem of an unsteady flow, which is often approached by assuming numerous simplifications. Presented computational model combines a 3D panel method with a force-free vortex wa... see more

The first part of this work describes the validation of a wind turbine farm Computational Fluid Dynamics (CFD) simulation using literature velocity wake data from the MEXICO (Model Experiments in Controlled Conditions) experiment. The work is intended to ... see more

Aerodynamic interactions between rotors are important factors affecting the performance of in-plane multirotor Unmanned Air Vehicles (UAVs) or drones, which are the majority of small size UAVs (or mini-drones). Optimal design requires knowledge of the flo... see more

An integrating wake rake concept is discussed here as very suitable for in-flight profile-drag measurements on gliders. The experimental setup is in essence the same as used with other integrating wake rakes, which uses a series of Pitot tubes that feed i... see more

This paper propose a residual based Galerkin method with Legendre polynomial as a basis functions to find the approximate solution of hypersingular integral equations. These equations   occur quite naturally in the field of aeronautics  suc... see more

Although theoretical tools for the design of winglets for low-speed aircraft were initially of limited value, simple methods were used to design winglets that gradually became accepted as benefiting overall aircraft performance.  As understanding was... see more
