Juggernaut Team 3 Completed Design Review Becca Arvanites: Structural Design Mark Egan: Structural Analysis & Stability Karl Kulling: RC Operator/communications & Propulsion Chris Savage: Stability & Structural Design Dawn Wheeler: Propulsion & RC Communications
Why a Four-Balloon Diamond Design? Benefits: Advantageous payload Stability in all directions Vectored Thrust
Control Systems Vectored Thrust: one servo controls pitch of motors, another servo controls yaw of motors RC control (human factors)
Aerodynamic Analysis Maximum Thrust (from table): 1.4N total from 2 large motors Mass: kg Maximum Acceleration = Thrust/Mass =.9-1m/s 2 Terminal Velocity = m/s Time Estimate: seconds
Design Evolution Reshaping control assembly to allow room for propellers to turn Motors mounted under control assembly instead of on top Extra bracing required on control assembly Psychological evolution: new improved team name! <-- motor mount prototype
Conclusions Designed for stability and payload rather than aerodynamics/speed Building left: attach motor mount to fuselage, balloon attachment net Testing: controls response, practice using rc controller
