aerodynamics of aircraft seminar topic

Abstract

Aerodynamics is a branch of dynamics concerned with studying the motion of air, particularly when it interacts with a moving object. Aerodynamics is a subfield of fluid dynamics and gas dynamics , with much theory shared between them. Judging from the story of Daedalus and Icarus, humans have been interested in aerodynamics and flying for thousands of years, although flying in a heavier-than-air machine has been possible only in the last hundred years.Aerodynamics plays an important role in the ....etc

Theory of Flight


Intended learning Objectives

After finishing this presentation, the student will be able to explain how the airplane is able to produce sustained flight over thousands of miles. They will be able to provide the name of the principle behind flight, and how the principle is used, and give the 4 forces acting on the airplane at all times.

Forces cont.

Drag
The force which opposes the forward motion of the aircraft.

Gravity

1. INTRODUCTION
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. If there is no fluid, there is no drag. Drag is generated by the difference in velocity between the solid object and the fluid. There must be motion between the object and the fluid. If there is no motion, there is no drag. Drag acts in the direction opposite to the direction of motion of the body.
A body moving through a fluid experiences a ....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 fli ....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

INTRODUCTION OF MICRO AIR VEHICLES

There has been recent interest in unmanned air vehicles with a largest linear dimension no greater than 6 inch Micro air vehicles (MAVs) are intended to operate in close proximity to a point of interest without being detected and should provide surveillance teams with critical information in a rapid-deployment urban-environment mission scenario.
Micro Air Vehicle is a small flight vehicle that uses lift-generating mechanism different from the mechanism used for larger a ....etc

helicopter flight theory ppt

The motion of the blades of a helicopter in flight conjures up the ancient vision of the airscrew: lifting surfaces rotating about a vertical axis and inclined at an angle so, as they turn, a lifting force is obtained from the resistance of the air. This recurring theme in the history of aeronautics was crystallized in the writings of Leonardo Da Vinci. Centuries later, but still many years before the perfection of the helicopter, master storyteller Jules Verne wrote a novel Robur le conquerant in which his hero ex ....etc

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

Helicams or coptercams are remote controlled mini helicopters used to obtain aerial pictures or motion images using video, still or motion film cameras. The remote controlled camera mount system allows pan, tilt and roll movements. A wireless onboard video transmitter downlinks the live signal to the camera operator, images can be recorded onboard, on the ground or both. The system is controlled by two operators with independent controls: helicam pilot and camera operator. One of the characteristics of helicams is their flexibility and small si ....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 a ....etc
