Preliminary design tool of conventional/coaxial/tandem helicopters

The thesis has the purpose of implementing a tool for a preliminary design of a helicopter. The tool is asoftware developed in Matlab and executes the calculations based on two theories: momentum and blade element. With this tool the flight performancescan be calculated, from hover to maximum forward speed, of three types of helicopter:conventional, coaxial and tandem. For sizing of each rotor configuration, the power required, forward velocities, range and endurance can be calculated
