Introduction The submarine’s general characteristics The hull Propulsion system Fins Propeller Security system Direction system Conclusion Questions??

Introduction The team Previous speed records Our goal Submarines Category Year Speed(knots) Omer4 One person, propeller 2001 7.192 Omer5 Two person, propeller 2007 8.035 Omer6 One person, non-propeller 4.916 Omer7 Two persons, non-propeller 2009 5.133

General Characteristics One person, Propeller Modeling done with CATIA V5R19 The hull Smallest in volume (105 in x 20 in x 24 in)

General Characteristics The propulsion system Similar to Omer4 Pedaling = rotor movement Variable pitch added The direction system Four fins Fully mechanical system

General Characteristics The security system Same as Omer7 Pneumatic system with actuators Dead man switch

The hull Constraints Methodology Ergonomic test Hydrodynamic analysis Fabrication Results

The hull (Constraints) Minimum required space for pedaling Size of the pilot Dimensions of the constraints Hip length 19 in Foot width 16 in Shoulder width Total length 70 in

The hull (Modeling) CATIA V5R19 NACA series 6 airfoils Technique Horizontal airfoils(shoulder and foot width) Vertical airfoils(hip length and minimum length) ellipses

The hull (Ergonomic test) Enough space? Sectional analysis -Knee fitting -Shoulder and tank fitting -Pedals fitting

The hull(Hydrodynamic analysis) Computational Fluid Dynamics Floworks by Solid works 2007 Simulates a fluid at a speed of 4m/s Trajectory of fluid + power of drag Optimal results

The hull(Fabrication) Resin infusion process Saves time and $$

The hull(Fabrication) Carbon fiber+ epoxy resin Difference: carbon/innegra fiber Nose window = polycarbonate(Lexan) Good impact resistance+ translucent
