All of us listen with curious intensity in our junior classes to the feat achieved by the Wright Brothers in 1903, when for the first time in history controlled and motor-powered aviation was achieved. Pioneering developments in the technology of aviation have come a long way since then. We have heard the term Drone: a word that conjures up an image of a body propelled and lifted by four rotors. To be more specific, that is known in engineering and aviation as a quad copter. And they are the next novel obsession in the world of aeronautical design and application. Drones have diverse applications in reconnaissance, photography, aerial survey and aesthetic reasons and have already become an iconic feature of technological innovation in the 21st century. However, the concepts that go behind its fabrication, structure, operation and working principles are slightly complex and may be intimidating to someone not involved in mechanical and fluid dynamics sciences. We at Team SCRO have therefore taken upon ourselves the task to deconstruct and demystify the operation and manoeuvring of a fully-functional drone: right from the fundamentals. We hope you have an enjoying and enriching read.
