Novel Concepts in Multi‐rotor VTOL UAV Dynamics and Stability
Emaid A. Abdul Retha · 2017
This chapter highlights novel concepts in multi-rotor dynamics and stability, such as tilting rotors, variable pitch control and flap vector thrust, and considers how these concepts can be used to improve the quad-rotor's performance. It describes a patented quad-rotor with tilting rotors, which built as a proof of concept of one type of electromechanically controlled quad-rotor. In recent years, the perception of the uses of the multi-rotor has increased due to its flexibility. It can to meet many of the requirements of vertical take-off and landing (VTOL) unmanned aerial vehicles (UAVs) for applications in reconnaissance and surveillance. To achieve innovative multi-rotor VTOL UAV dynamics and stability, performance enhancements are required. This is achieved by increasing the actuations and adding electromechanical mechanisms to ensure improvements in multi-rotor performance. The chapter discusses the types, design, modelling and applications of different types of electromechanical multi-rotors.
