10 Structural Analysis  Structure:65g x 1 = 65g  Motors:93g x 2 = 186g  Motors: 269g x 1 = 269g  Propellers: 5.2g x 3 = 15.6g  Servos:43g x 3 = 129g  Radio Gear:46g x 1 = 46g  Batteries: 260g x 1 = 260g  Total Mass: approx g  Payload: approx g  Dimensions: Length: 2m Width: 1.25m Height: 1.5m

11 Aerodynamic Analysis  Helium Required: Lift=ΔρVg=17.15N Assuming two balloons, their radius must be.53m to generate the necessary lift Thrust must be equal to drag in steady flight Thrust = Drag = 2.64N v 2 =2D/ρSC D v=1.5m/s Total course time estimate: 60 to 70 sec.

12 Control Analysis  Yaw control is provided by two oppositely facing, fore and aft mounted small motors  Pitch control is provided by the third, main drive motor, which pivots about a horizontal axis  Control surfaces will be added if we deem them necessary after initial flight testing
