Design and construction of an innovative helicopter system

The purpose of this thesis is to redesign the helicopter rotor systems with an innovative approach. The conventional helicopter system is completely regenerated and the tail rotor systems have been removed. The required anti-torque is balanced by alternative systems. In the new system, the main rotor of helicopter is placed under the helicopter. Some measuring systems are used to compare the theories of helicopter design namely, blade element and momentum theory. Measured data are verified by the analysis. The concept of helicopter is completely changed at the end of the thesis. The main rotor is established in a different position from the conventional helicopter. The produced torque by the main rotor is balanced by the innovative design of helicopter. The new helicopter system is more compact and stable than conventional helicopter systems. The new system is lighter. Transmission problems have disappeared due to removable of the tail and the tail rotor. Key Words: Helicopter, Anti-Torque, Tail Rotor, Theories of Helicopter
