Project Report from the year 2008 in the subject Instructor Plans: Craft / Production / Trade - Electronics Engineering, grade: 90, Sir Syed University Of Engineering & Technology, language: English, abstract: Quad rotor helicopters have become increasingly important in recent years as platforms for both research and commercial unmanned aerial vehicle applications. This progress report explains work on several important aerodynamic effects. These vehicles have 4 identical rotors in 2 pairs spinning in opposite directions, and possess many advantages over standard helicopters in terms of safety and efficiency at small sizes.
