Conceptual design of a multirotor aerial system incorporating secondary rotors for attitude correction

Multirotor aerial vehicles are extensively employed in applications requiring a stationary surveillance platform to monitor a situation on the ground for a specific duration. In most cases, these systems are small in size and weigh <; 10Kgs. This paper presents a design methodology employed to develop a multirotor system exceeding the conventional size and weight category. The study includes modelling and simulation framework incorporating ground and gyroscopic effects to analyze the performance of a quadrotor having four additional secondary rotors for attitude correction and maneuvering. The paper also analyzes the effect of size and location of the secondary rotors on the performance of the system and further reports system response to RPM variations of the rotors.
