ABSTRACT
Selective laser sintering (SLS) is technique by which parts are building layer by layer. The SLS is a free form fabrication method to create components by precise thermal fusing of powdered materials.
This is durable, economical and fast. The SLS is another form of rapid prototyping. This selective laser sintering (SLS) is one among the rapid prototyping which include stereo lithography (SLA). This method has also been extended to provide direct fabrication of metal and ceramic objects and tools. With this method ....etc

Computational Fluid Dynamics (CFD) is an extremely effective tool to solve problems involving mass and even heat transfer. Problems with varying degrees of complexities can now be easily solved with the help of appropriately written CFD codes. A CFD analysis is performed to:1)understand the nature of fluid flow around differsnt geometries like an aerofoil or any other shape for that matter.2)find the lift and drag effects for an aerodynamic structure.3)analyse the heat transfer by fluids in devices ranging from radiators to furnaces to gas turb ....etc

1.AN INTRODUCTION TO AIRCRAFTS
1.1 Components of Aircraft:
Aircrafts come in many different shapes and sizes depending on the mission of the aircraft, but all modern airplanes have certain components in common. These are the fuselage, wing, tail assembly and control surfaces, landing gear, and power plant(s).
• The fuselage:
It is the body of the airplane that holds all the pieces of the aircraft together and many of the other large components are attached to it. The fuselage is generally streamlined as much as ....etc

i need it for general study in college . i just want to tell brief description how flight started by man made engine. how it evolved during more in world war 11 . and also want to improve my flight knowledge . whats aero dynamic mean?
today if you go to any sport product they say our material or thing just work on aero dynamic model it will give you more comfort .. blah blah
is it a crime to know about flight you ask description. ....etc

ABSTRACT
Drag is a mechanical force generated by a solid object moving through a fluid. For drag to be generated, the solid body must be in contact with the fluid. Drag is generated by the difference in velocity between the solid object and the fluid. Drag acts in the direction opposite to the direction of motion of the body.
Microbubbles is a drag reduction device that reduces skin friction of a solid body moving in water by injecting small bubbles into the turbulent boundary layer developing on the s ....etc

ABSTRACT
Micro air-vehicle is a small flight vehicle that uses a lift-generating mechanism that is different from the mechanism used for large aircrafts. In micro air- vehicles, one of the methods for creating lift is a special flapping mechanism, which consists of translation and rotational motions of wings. This is adopted from one species of insect Encarsia Formosa. For this purpose, a 6-link mechanism is designed for three positions of wings by synthesis using kinematic inversion, and dynamic force ....etc

SYNOPSIS
Helicopter is one of the earliest ideas for achieving flight. The advances in helicopter technology made it an extreme flying machine. In this seminar I discuss the historical backgrounds and early concepts of helicopter, then introducing the aerodynamic theory and principle behind helicopters, discussing the most potent mechanisms that are used in it. Also different configurations of helicopters have been described. Then discussing the first analytical theory to consider for a helicopter in for ....etc

THE NRL MITE AIR VEHICLE


ABSTRACT
Micro Air Vehicles (MAVs) offer the promise of affordably expendable, covert sensor platforms for a range of close-in situational awareness activities. Since 1996, the US Naval Research Laboratory (NRL) has been developing technologies that will enable Navy-relevant missions with the smallest practical MAVs. This effort includes the development and integration of sensors, avionics, and advanced intelligent autopilots for f ....etc

ABSTRACT


MICRO AIR VEHICLES




Have you ever thought of a class of air vehicles which are less than 15 cms in size (most prominent linear dimension), can hover for two to three hours in air at a velocity of 20 to 30 mph at an altitude of 600 meters or even higher. This seminar will give you an idea of such vehicles called MAVâ„¢s (micro air vehicles). A dwell into the design and aerodynamics of such vehicles would be quit ....etc
