"If you are in trouble, anywhere in the world, an airplane can fly over and drop flowers, but a helicopter can land and save your life"

Igor Sikorsky

INTRODUCTION

The first controlled and sustanined flight of an airplane was conducted in december 1903 by:

5. Flight Controls

Rotors

A helicopter or chopper is a type of aircraft that uses rotating wings called blades, imagine that is like having a huge fan over an structure.

drive system

The drive system, trought a main transmission, gearboxes and shafts, allows that movement happen.

engine

There are reciprocating and jet engines and they work with different type of fuel.

HYD SYSTEM AND FLIGHT CONTROLS

In helicopters, the hydraulic system is in charge of flight controls. The purpose of the hyd system is give you the necesary force to move and control the helicopter.

The system works using a pump to move hidraulic fluid trought pipes and flexible hoses until a hyd actuator, which moves the swashplate and transfer the movement to the rotors

HYD SYSTEM AND FLIGHT CONTROLS

We have three types of flight controls: "NO ONE" Hydraulically Assisted Fully Hydraulic

electrical system

structure

Helicopters systems are supported in structures made mainly of aluminium, they are like the skeleton of the aircraft and suffer all the charges in all the phases of flight

Landing gear

Skids are useful for a lot of landing configurations in environments like water and snow, however they are installed in small and médium helicopters. Wheel configuration can be fixed or retractable and they are installed in medium and heavy helicopters.
