TABLE OF CONTENTS
The Team America Rocketry Challenge requires us to design, build, and fly a rocket that can
carry an egg at least 750 feet into the air within the duration of 40 to 45 seconds and
land it safely using a specifically sized parachute.

RockSim
Pros(+) Cons(-)Payload system present Not enough dimensioning
Feasible recovery system Egg compartment too complex
Egg safely stored No launch lugs
Shows connections between body tube Does not show how altimeter is attached
All criteria met No specific engine model
Aerodynamic Nose cone oddly shaped
DAVID’S SOLUTION
Pros (+) Cons (-)Appropriate height Fins are too big/ no dimensioning
Accurate dimensions No payload system indicated
Proper Nose Cone Shape No connecting system from top and bottom sections of rocket
Possible Choice for Recovery System
Does not show how egg will be stored safely
Appropriate amount of launch lugs Does not show how altimeter will be attached
Ease of construction Fin shape is inappropriate for the large rocket
BRIAN’S SKETCH
Pros (+) Cons (-)
Well dimensioned Fins bizarrely shaped
Labeled rocket parts Egg capsule not attached to rocket
Proper Nose Cone Shape Not enough launch lugs
Criteria met Altimeter placement not feasible
Aerodynamic Parachute is complex
Ease of construction Recovery system unfeasible
NEELAM’S SKETCH
Pros (+) Cons (-)
Good recovery system Unnecessary extra shock cords
Accurate dimensions Only one separation
Ease of construction Missing dimensions
Reasonable fin choice Parts are unlabeled / parts missing
Shows connection of separate parts Confusion of placement of parts
Reasonable place for egg capsule No motor
