E N D
Aerodynamic Analysis 3 Balloons in straight line • Maximum Lift • Minimum Drag
Aerodynamic Analysis Vehicle Mass Estimate: = mass (thrust system) +mass (steering system)+…….+etc. = 0.796 Kg
Aerodynamic Analysis Vehicle Drag Estimate: • Assuming Drag is Dominated by balloon (Frontal Area)
Aerodynamic Analysis • Assuming Maximum Velocity of 4.4 ft/s:
Aerodynamic Analysis System Placement: • All batteries, receivers, & non-thrust producing equipment placed as close to Center of Gravity as possible, in order to maximize stability • 4 AA batteries (112g), 1 rechargeable battery pack (105g) • 2 Motors, placed as far apart as possible, located in the rear of vehicle, in order to maximize steering capabilities
Aerodynamic Analysis Method of Vehicle Control: • One servo to adjust pitch of motors, control elevation (z) of vehicle • One servo to adjust yaw of motors, control horizontal (x, y) direction of vehicle
Aerodynamic Analysis Estimated Duration: From previous thrust & drag analysis:
