Drones are becoming more popular everyday. They are being used as toys and industrial machines. As you read, you will learn the functions of the different parts of a drone, and the physics that make a drone fly. To start with, a drone needs a powerful, yet lightweight battery. Most drones, both industrial and toy, are powered off of Lithium-Polymer batteries or LiPos. Every piece of electronic equipment in the drone needs power from the battery. This is where the power distribution board comes in. The battery connects to the power distribution board, or PDB. The board then distributes power to all of the electronic components. Many PDBs include extra pieces of tech to improve a consumer’s experience with a drone. For instance, most modern boards have BECs. A BEC, or battery elimination circuit, regulates the voltage from the battery, stepping it down to something acceptable for fragile components. One component that is powered by the PDB is the set of electronic speed controllers, or ESCs. The ESCs control brushless motors, one of two kinds of motors used in drones. Brushless motors have two main parts, the rotor, and the stator. The rotor contains magnets and rotates (hence the name). The stator contains electromagnetic coils connected in pairs. There are 3 sections of coils in the motor, each connected to a wire. This is where the ESC comes in to play. It takes the voltage from the PDB, combined with a signal from the flight controller and turns different sections on and…

Drones have recently hit the news time and time again within the last decade, and frequently lead to a debate. The majority of those heated conversations often involve the United States of America. Those passionate discussions have ignited a spark in a series of countless debates dealing with drones and the future they possess with the United States of America. Some may not know, but drones are also known as Unmanned Aerial Vehicles, or UAV’s for short. A UAV is exactly what it sounds like.…

limitations of the airplane. His successful design of the helicopter would draw interest from military leadership and become the spark that would ignite the future explosion of army helicopters. Igor himself highlighted the lifesaving capability of the helicopter as one of its greatest capabilities. The first rescue by helicopter happened on 21 April 1944 when a 1st Air Commando Group L-1 was shot down in Burma. The L-1 was carrying a pilot and three British soldiers. Since the rice paddy…

1. Introduction Questions arise, people are asking how their grandfather, a family friend, or even a community member once survived the Vietnam War after being severely injured. Flight nurses, would be the answer. Flight nurses played a vital role in the transportation of wounded soldiers by serving to save many lives in the Vietnam War. Flight nurse are nurses that fly around in helicopters to different places of a war zone. They pick up severely wounded patients that need to be escorted…

Drones are the newest airborne craze to infiltrate the skies. The military is the most noteworthy entity to explore the immense potential of using an unmanned aircraft. History traces the first official unmanned aerial vehicles (UAVs), back to the V-1 rockets (doodle bugs) of the Second World War. The idea of a flying vehicle that could cruise over enemy territory without risking a pilot has been the primary focus of drone development. However, as these little flying remote controlled…

As our technology continues to advance and develop, many innovations are emerging to create more efficient solutions to our problems, especially in terms of warfare. Weapons and tactics continue to evolve with time and experience, but with these progressions come hesitancy and controversy about their reliability and morality. Drone combat is one form of new fighting methods that have caused a lot of uproar within communities. Drones, or Unmanned Aerial Vehicles (UAVs) are unmanned aircrafts used…

Drones Impact Analysis Introduction The term Drone as referred to as Unmanned Aerial Vehicles (UAV) that can be utilized for anything from military or commercial purposes to individual excitement. Expansive organizations “for example,” Facebook, Google and Amazon have invested heavily inquire about identifying with drones. Lamentably, most organizations are kept away from their utilization of drones. The similarly as with present day technology most nations don't have clear direction controlling…

Although, in some situations the involvement may be extreme, they feel a weight lifted off their shoulders knowing the child is always in good hands. Bre is my best friend and her mother hovers more than a Robinson R44, one of the world’s most popular helicopters. Facing a hard life and seeing some of its worst aspects makes a parent want better for his/her child, but is hovering the answer? One of the main reasons my best friend’s mom keeps a close eye on her daughter is because growing up,…

On March 30, 2013, a Eurocopter AS350 B3 helicopter crashed during a search and rescue mission (SAR) (NTSB 911AA Eurocopter, 2014). Earlier that day an individual wrecked on a snowmobile near Talkeetna, and called the Alaska Department of Public Safety (DPS). The dispatcher who received the call tried to set up a local land rescue. However, no local troopers were on duty, and no locals with SAR experience were willing to take the mission due to the deteriorating weather conditions. Once the…

Drones should be used for warfare instead of humans, because they they have higher morality standards. Drones not only take the risk out of war, but they also crush humans in the skill of precision. All of these things combined make it a more modern and moral approach to warfare Drones take the risk out of war by taking soldiers off the battlefield and put them with a remote controller inside of a bunker. Shane states “The drone's promise of precision killing and perfect safety for operators…
