Lighter Than Air Vehicle Completed Design Review Team Two “Believe”

The Team  Mariel John  Victor Figueroa  Yonatan Tekleab  Nabori Santiago

Objective  Present our final LTA design  Explain changes we made  Provide detailed drawings

Final Design For our final design, we chose to arrange three balloons linearly and use a triangular truss structure.

Believe

Control Systems  Turning Capabilities –Differential Thrust  Two large motors positioned on the ends of a stable carbon fiber rod  Pitch –Elevator  A piece of wood with air from a small motor blowing over it  Wood is attached to servo and can be moved

Aerodynamic Analysis ObjectQuantity Mass (kg) Big Engines Small Engines Propellers Receivers Servos Battery pack Balloons Structural Framework Total Weight :14.27 N

Aerodynamic Analysis

 Required Lift is less than Maximum Lift

Design Evolution and Analysis  Then and Now… –From two balloons to three –New control systems –Great new name  Why change? –A closer look at possibilities –Familiarity with materials and process –Deeper thought about flying

I BELIEVE I CAN FLY!
