Gimbals of UAVS

UAV Gimbals
A gimbal is a pivoted support that allows the rotation of an object about a single axis. A set of three gimbals, one mounted on the other with orthogonal pivot axes, may be used to allow an object mounted on the innermost gimbal to remain independent of the rotation of its support.  For example, on a ship, the gyroscopes, shipboard compasses stoves, and even drink holders typically use gimbals to keep them upright with respect to the horizon despite the ship's pitching and rolling.
                                       





Gimbal contents from two main items:
Gimbal actuator:
The gimbal was first described by the Greek inventor Philo of Byzantium. Philo described an eight-sided ink pot with an opening on each side, which can be turned so that while any face is on top, a pen can be dipped and inked - yet the ink never runs out through the holes of the other sides. This was done by the suspension of the inkwell at the center, which was mounted on a series of concentric metal rings so that it remained stationary no matter which way the pot is turned.
Gimbal Controller:
it's an electronic board considered with intermediate between controller (man or autonomous) and Gimbal actuator.
Gimbal controller does this by burn a suitable code for controlling Gimbal actuator.


UAV uses Gimbal:
Gimbals are also used to mount everything from small camera lenses to large photographic telescopes.



Thus UAVs can use gimbal if it mount cam to ensure getting all angles of photography.

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

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.

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.

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.

Introduction to unmanned aerial vehicle (UAV)



  Unmanned Aerial Vehicle (UAV)
What is UAV ?


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.
