Drones

Multirotor drones are used across a wide range of applications today. As their roles and operating environments become more diverse, performance requirements place increasing demands on design choices. Multirotor design involves several key factors, including maneuverability, stability, payload capacity, flight duration, safety, and reliability. These factors are closely interconnected, and improving one often requires trade-offs in others—safety being the primary constraint. In this post, we […] Read More

This is one of the methods to launch airplane drones, because airplanes need initial speed in order to fly. Catapults are used in order to throw airplanes into the air easily and quickly, where there might not be enough distance to speed up, or the drone might not have the gear to speed up (which saves weight and control systems). Catapult launched airplanes will need […] Read More

Batteries provide essential power to the motors, receivers and controllers. For multirotors, the most commonly used batteries are Lithium Polymer (LiPo) types, as their energy efficiency is high. Usually 3-4 cell batteries are used, which provide currents of up to around 5000 mah (miliamperes – hour) capacity. To understand what mah means, consider this example: a 3000 mah battery will last 3 times longer than […] Read More

This is the angle between the longitudinal axis of the aircraft and the horizontal axis, when the drone flies inclined. For example, when the drone flies in perfectly horizontal position, the bank angle is zero. When it starts to turn its axis the bank angle starts to increase. When flying straight, planes bank angle is zero and when making left or right turns, they have […] Read More

It measures the speed of the drone relative to the air, by measuring the positive and negative pressure differences around the drone. When purchased, they usually come together with pitot tube and connection cables. It is recommended for advanced users or drones only, as it necessitates an extra layer of control and tuning. Through pitot tube, the pressure is measured and then this is converted […] Read More

Drones are used more and more all the time. It is for sure that we will see more applications in the near future, due to increasing battery power and auto piloting capabilities. Here is a summary of uses of drones at present: Military Examples: Reconnaissance or Attack drones   Visual inspection, photography or video recording Examples: Wildlife Control, Ski, Fire, Border Patrol, Stadium Recording, Surveying […] Read More

Planes: Unmanned planes follow the same principle as manned planes, which is based on lifting the aircraft by means of pressure differential lifting force at different sides of the wings, when a propeller in the front pushes the air towards the wings. Planes fly forward faster than helicopters or multirotor drones but they cannot hover in the air like them and do not have the […] Read More

So, what are drones? They can be defined as robotic devices, without a human on board, that are either remote controlled by humans or moving autonomously. Almost everyone, immediately thinks that drones represent only flying unmanned vehicles, but technically it is not true. Unmanned Ground or Sea Vehicles are also drones. However, our focus in this book is flying drones, and from now when you […] Read More
