2.23 Hydrofoils & Propellers SDV Propeller Design Project Spring 2007 Introduction: A design project for 2.23 Hydrofoils & Propellers entails the design of a propeller for a notional Seal Vehicle (SDV). The desire is to design a propeller for a relatively high speed SDV (4 m/s). Figure 1 shows the hull shape for the SDV. The design effort will include the parametric design of the propeller including sizing , powering and efficiency calculations. A blade design will also required for the propeller along with consideration regarding cavitation in the design of the blade sections. Design Specifics: The overall specifications for the project are outlined below: - Design Speed 4 m/s - Inflow wake velocity variation +/-0.3 m/s - Hull length: 9.3755 meters - Hull diameter: 1.5 meter - Design depth: 3m to hull centerline - Propeller speed: TBD, assume gearing can match motor - Propeller type: free tip single screw (contra-rotating design optional) - Hull drag coefficient Cd = 0.15 based on frontal area
