Flight Performance of Nano Aerial Vehicles with Flapping Wings: Experiment-Based System Modelling

Boek - Dissertatie

The use of drones is increasingly popular in various applications. These applications go from surveillance tasks to filming during sports events and help during search and rescue operations. The use of drones indoors and in confined spaces on the other hand is not always obvious. These specific applications impose requirements on small size, autonomy and agility. Recent evolutions however in miniaturisation of mechanical systems have applications in diverse sectors, including the field of aerial systems. Several designs for indoor flight are in development phase. An alternative for multi rotor systems as often used in drones is the concept of flapping wing systems which could offer significant advantages in agility and efficiency. A flapping wing aerial robot is a dynamic system in which the reciprocating motion of the wings at the same time generates the forces to hold the robot in the air and the forces to ensure a correct execution of the flight path. The stability of the system has to be ensured both in nominal conditions and when perturbations occur during flight. Previous research activities at KU Leuven have resulted in the KUlibrie prototype in an experimental way. The improvement of a generic flapping wing system, its flight mechanics, power consumption and control laws require in-depth physical and numerical modelling. The objective of this research is to develop a model for a flapping wing vehicle which can be validated with the current prototype. This model comprises the drive line, the wing flexibility and the force production of the wings. Next a sensitivity analysis of the different parameters in the model allows to study and optimise the performance of the flapping wing drone.
