Abstract: The three dimensional (3D) flight of a golf ball at taking into account the Magnus effect is studied in the paper. For this purpose it is composed a system of six nonlinear differential equations. To determine the 3D... more
It is a precious knowledge of ancient india. this script was originally composed by mahrshi BHARADWAJA, the great indian sage around 5000 BC ,it content english transtation of some of its sanskrit stotras and shlokas.before wright... more
Written for students of aeronautical engineering and based on a range of detailed aircraft design projects, this wide-ranging book draws together the elements of aircraft design and will support any aircraft design project. Written by... more
Vent holes can be used to reduce the aerodynamic pressure loads on nonstructural elements of buildings. The analysis of these loads applied on nonstructural elements of buildings (window panes, closure panels, etc.) with vent holes, under... more
Wind tunnel testing has been carried out on nine-knitted single jersey fabrics (100% polyester) using cylinder and leg models to determine its aerodynamic behaviour over a range of speeds (20–80 km/h) representative of sports activities.... more
The unsteadiness such as boundary layer transition and turbulence at high angles of attack result in lift loss and increase in drag over an aerofoil. Numerous techniques such as suction at slots, flaps, bumps, high lift devices etc. have... more
: A full-scale wind tunnel test of the UH-60A airloads rotor was recently completed in the National Full-Scale Aerodynamics Complex 40- by 80-Foot Wind Tunnel. The rotor was the same one tested during the landmark 1993 NASA/Army UH-60A... more
ABSTRACT The headway of wind power generation is a great blessing to help meet up the electrical power demand day by day. The strongest challenges for wind energy conversion system (WECS) are to handle the intermittency of wind and to... more
A three-dimensional-membrane-type wing is investigated applying fluid-structure-interaction computations and complementary experiments. An analysis for three Reynolds numbers is conducted at various angles of attack. The computations are... more
The main objective of the analysis is to study the detailed aerodynamics & the characteristics of the lift & drag of the aircraft with the canard wing & the co-efficient of pressure & flow separation patterns over the wings at different... more
Abstract The paper presents a comparative analysis of recent simulations, conducted in the framework of a French-German collaboration on LES of Complex Flows, for the so-called Ahmed body at Reynolds number 768000 and slant angle 25. It... more

This paper is focused on numerical investigations that analyze the advantages obtained from high-aspect-ratio wings with unconventional roll control strategies based on wing twist morphing. The sailplane G103-B, produced by the GROB Werke... more
A computational fluid dynamics (CFD) modelling study is undertaken integrating the air-fired and oxy-fuel combustion cases for chemical reactions, radiative heat transfer, and gas compositions into a 3-D hybrid unstructured grid CFD code.... more
This document was created in hopes for a safer, more prosperous future of aeronautics. This document seeks to present an otherwise highly complex topic in the framework of game theory, economic or otherwise with players being governing... more
Aerodynamics is the study of movement of air when the air interacts with a solid object. The study of aerodynamics is needed when resistive forces act on the vehicle, particularly when the vehicle is moving in a fluid medium. The... more
TURCAN Greatly Reduced Turbulence and Drag of Aircraft Repetitive MetaStable Cancellation of Turbulence Flow in large Pipelines can also be improved All aircraft except gliders have enormous turbulence losses during flight. Gliders... more
Dynamically changing background ("dynamic background") still presents a great challenge to many motion-based video surveillance systems. In the context of event detection, it is a major source of false alarms. There is a strong need from... more
According to the universal desire to reduce greenhouse gas emissions and sustainable energy supply to meet the increasing need of energy for human, many efforts have been made for the development of renewable energy including wind power... more
In the world of automotive, lots of research has been done yet on overall vehicle. Researchers improved every single part of vehicle but wheel is one of the part that hasn't changed much in automotive history. In case researchers got... more
A new computational model for the aerodynamics of vertical-axis wind turbines is introduced. It is based on the double-multiple streamtube concept and it incorporates the capacity of dealing with rotors whose blades follow... more
This work is on the aerodynamics design of the body and frame of a motor tricycle using SolidWorks 2011 modeling system. Its Computational Fluid Dynamics (CFD) feature was used to run simulation tests at a target speed of 150 km/h to... more
The measurement accuracy of volumetric airflow velocity is a real issue for aircraft. Several aeronautical accidents derive from Pitot sensors static and total pressure measurements. To control and assess Pitot sensors measurement... more
This work describes advanced numerical aero-hydro-servo-elastic simulations of a floating offshore wind turbine using a multi-body vortex-particle based solver. The floating offshore substructure considered in this study is the spar-buoy... more
