Abstract:

In this thesis, a decision methodology is generated using purchase price of a helicopter related to its geometry sizing and performance parameters during design and technology factors in order to compare these prices with investment costs. MATLAB® and Minitab® software were used for technical computing and methodology implementation. Firstly, helicopter base price formulation was verified by 21 helicopters. Then, technology parameters were defined which effect base price value. After that, total base price was generated which contains R&D investments. Finally, the methodology was implemented on real samples, BELL429 composite shaft and Sikorsky UH-60 composite tail cone, in order to show that the methodology can be used as a practical tool for decision makers.
