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

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.

Servo motor Selection for your uav

Servo motor Selection for your uav

for fixed wing uav and tricopter uav you have to use a servo motor to move the control surfaces, the selection of the suitable servo for your uav is depend on some parameters in this post we will discuss what is a servo motor and what are the selection parameters of the servo motor   

Why MultiRotors Uav?

Why MultiRotors Uav?
 Multirotors Uav have many benefits in the field of Security,farming, surveys, aerial photography and Rescue.

power calculations of multirotors uav

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.

FAN Wing

What is FAN Wing UAV?

 Fan wing is a new concept for a type of STOL (Short Takeoff and Landing) UAV.  It is distinct from existing types of UAV by using a fixed wing with a forced airflow produced by cylindrical fan mounted at the leading edge of the Wing.

Brushless Motor Selection parameters

Brushless Motor Selection parameters

There are two main criterion's to consider when choosing a motor:

1-Electrical characteristics 
2-Physical characteristics

Electronic Speed Controller Selection parameters

Electronic Speed Controller Selection

Electronic Speed Controller:

An electronic speed control or ESC is an electronic circuit with the purpose to vary an electric motor's speed, its direction and possibly also to act as a dynamic brake. ESCs are often used on electrically powered radio controlled models, with the variety most often used for brushless motors essentially providing an electronically-generated three phase electric power low voltage source of energy for the motor.

Mini UAV CONCEPTUAL and PRELIMINARY DESIGN "Weight Sizing"

Mini UAV CONCEPTUAL and PRELIMINARY  DESIGN "Weight Sizing"

in the last post we introduced a general view about conceptual and preliminary design, and as we discussed preliminary design divided into three different stages

UAV CONCEPTUAL and PRELIMINARY DESIGN

UAV CONCEPTUAL and PRELIMINARY DESIGN

CONCEPTUAL DESIGN:

The conceptual design process is shown in the following. It is a low fidelity study.  It starts with the overall requirements and specifications derived from the analysis of the mission requirements imposed on the required mini UAS.

Lift Generating

Lift Generating

The most important component of UAVs is Wing at fixed wing UAV and rotor at multi-rotor UAV that generate lift to raise UAV up.

Consederations when choosing a quadcopter for sale

What should you consider when choosing a quadcopter for sale?

there are many points  you have to consider it when you choosing a quadcopter   

• Price

• Replacement Parts

• Features

• Assembly

•  Flight Control Board

UAVs Applications

Applications of UAVs:
there are many applications for UAVs can service society and military services by add some component to UAVs to do what we want. In this topic we will discuss every applications mentioned above.

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

Introduction to unmanned aerial vehicle (UAV)

  Unmanned Aerial Vehicle (UAV)

What is UAV ?

quadcopter UAV from drones

The unmanned aerial vehicle (UAV) is a remotely piloted 
or self piloted aircraft that can carry cameras, sensors, 
communications equipment or other payloads.

The most of the world's modern armed forces are 
recognizing the tremendous advantage of using UAV 
in military operations. UAV is easier to built and less 
expensive to acquire than manned vehicles.

 General rules

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