Quadrotor: a detailed analysis on construction and operation

Ray, P and Panda, M P (2014) Quadrotor: a detailed analysis on construction and operation. BTech thesis.



It is a type of an unmanned air vehicle (UAV) which by its name suggests that consists of 4 engines to drive it. Usually we use BLDC motors and propellers as the engines of a quad. Its motion and dynamics can be compared with that of a helicopter in regards to its transverse and longitudinal motion. It has various uses in various fields of military, business, rescue mission, modern warfare etc. They have a vertical take-off and landing system. Unlike a helicopter the propellers or blades of a “Quadrotor” have fixed pitch. Control of vehicle motion is achieved by altering the pitch and/or rotation rate of one or more rotor discs, thereby changing its torque load and thrust/lift characteristics. This will be explained in details in course of the following discussion. If we look into history of the “Quadrotor”, we get to know that it was the first step towards vertical take-off and landing vehicle. At first it was a manned vehicle but now mainly the research is focused upon a unmanned “Quadrotor” which is controlled with the help of electronic signals and various other mechanisms.
