Abstract
In this thesis the design of a coaxial micro helicopter is presented and based on the design, a
model is fabricated. The thesis starts with the introduction on the previous models of micro
helicopters like the Coax and the Epson. The different configurations of the micro helicopters in
use are discussed and a detailed introduction on the principle of working of the coaxial
configuration of helicopters is presented using the principle of conservation of angular
momentum. The advantages and disadvantages of the coaxial configuration over other
configurations are then given. The design process starts with the identification of the individual
mechanical and electrical parts. The working of the mechanical and electrical components is
individually discussed and their necessity for the fabrication process is explained. Further, the
mechanical parts are designed and assembled using CATIA V5R17. Then, the model of the
coaxial helicopter is fabricated and is successfully flown by remote control mechanism. The
individual forces acting on the rotor blades of the fabricated model are identified and their
directions are defined. By using standard equations, the values of the individual forces are calculated for the rotor blades as well as for the entire helicopter body.Using the values of the
forces obtained on the rotor blades, a static analysis is presented using ANSYS.
Finally, the conclusions and inferences arising in course of the work are presented and the
references used in this work are mentioned.
