Quadcopter Mechanics

  Flight Mechanics 

   In order to learn how to control a quadcopter, you'll need to learn a bit about quadcopter mechanics - how quadcopters fly by adjusting rotor speeds. Quadcopters have different flight mechanics than conventional aircraft such as airplanes and helicopters. They are Vertical Take Off and Landing (VTOL) aircraft similar to helicopters; however their attitude and flight mechanics are vastly different.

Control System of UAV 

Introduction:
 
  There are two main types of UAV available that are suitable for surveying work. The first is a fixed wing model.

These compact, lightweight units are built for one-man survey operation, with a 1.6 meter wingspan and weighing only 2.7 kilograms. They are ideal for aerial mapping and terrain modeling larger areas, including mine sites and stockpiles, and undertaking topographic surveys.

Calculation of Multirotor UAV Required Power

to calculate the power required for an uav rotor craft or multirotor uav you have to define your flight conditions and design requirements

Fixed Wing UAV fly vertically!!

How Fixed Wing UAV fly?

As we know Fixed Wing UAV to fly we need to start engine and take the suitable Velocity of UAV to make lifting of UAV by Wing.

How to build your multi rotor from scratch Tutorials

In this Tutorial we will  show you how to build your 
own multi rotor from scratch. This is especially useful to beginners.
There will be 3 parts  series.
In Part 1 we will introduce what are the components needed to build your multi rotor
in part 2 we will show you how to choose every component in the multi rotor
In part 3 we will assemble your multi rotor and making it ready to fly
 by tuning the multirotor to optimize its flying performance

 General rules

more engines mean more power and more lift. That means more batteries. That means more time in the air

Hexa-copter

What is the Hexa-copter?
 A Hexa-copter is a multi-rotor aircraft that uses six motors and propellers, Hexa-copter is unlike a helicopter that rises on a single column of air, the Hexa-copter rises on sex columns of air making it more stable than other multi-rotors like tri-copter, quad-copter.

Octa-Copter

What is the Octa-copter?

 An Octa-copter is a multirotor aircraft that uses eight motors and propellers,Octa-copter is unlike a helicopter that rises on a single column of air, the Octa-copter rises
on eight columns of air making it more stable than other multirotors like tri-copter,quad-copter and also hexa-copter.

                 more no of rotors -------> more stability------> low maneuverability

 

Quad-copter

What is the Quad-copter? 

A quad-copter, also called a quad-rotor helicopter, quad-rotor, is a multi-rotor helicopter that is lifted and propelled by four-rotors. Quad-copters are classified as rotorcraft, as opposed to fixed-wing aircraft, because their lift is generated by a set of revolving narrow-chord airfoils.
The quad-copter rises four column of air to make that more stable than tri-copter and helicopter.

.

Tri-copter

what is Tricopter?
A tri-copter is a multirotor aircraft that uses three motors and propellers
 (arranged in a horizontal triangle) to stay airborne. Tri-copter is unlike
a helicopter that rises on a single column of air, the tri-copter rises
on three columns of air making it more stable. It uses 3 standard brushless
out-runner motors.

Introduction to Multi rotors

what are multi-rotors ?

A multirotor or multicopter is a rotorcraft with more than two rotors. Multirotors often use fixed-pitch blades, whose rotor pitch does not vary as the blades rotate; control of vehicle motion is achieved by varying the relative speed of each rotor to change the thrust and torque produced by each.
Due to their ease of both construction and control, multirotor aircraft are frequently used in model and radio control aircraft projects in which the names tricopter, quadcopter, hexacopter and octocopter are frequently used to refer to 3, 4, 6 and 8 rotor respectively.
