Abstract
Helicopter performance depends on the design of the rotor blades such as length of the blade, selection of airfoils and blade material. For heavy lifting, a large rotor works best, but short blades reduce drag and ultimately allow for higher maximum speeds. There is an approach to implement both configurations in one design where the design en-counter huge centrifugal forces, requiring large actuators to pull the rotors in. so for high lifting performance helicopter requires large rotor blad ....etc

Autonomous Stabilization System for a Coaxial Helicopter
ABSTRACT
The purpose of this project was the design of a fully autonomous stabilization system intended for systems capable of intelligent programming and navigation. This means that the design focuses mainly on the control feedback systems that control the helicopterâ„¢s motors that then provide lift to increase and decrease altitude, and produce a tilt about the helicopterâ„¢s central vertical axis which would be used for stabilization and potentially later ....etc

INTRODUCTION
The Apache helicopter is a revolutionary development in the history of war. It is essentially a flying tank -- a helicopter designed to survive heavy attack and inflict massive damage. It can zero in on specific targets, day or night, even in terrible weather. As you might expect, it is a terrifying machine to ground forces.
In this topic, we'll look at the Apache's amazing flight systems, weapons systems, sensor systems and armor systems. Individually, these components are remarkable pieces of technology. Comb ....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
