Lift is Such a Drag!

Our project tests the air resistance of various shapes of blimps. We wrote a computer program to calculate the shapes and volumes for the model balloons, which we made out of polystyrene. Then, we attached each blimp model onto a thin piece of wood rotated by a gear motor. If the blimps were aerodynamic, they spun faster as they create less air resistance. We also calculated the lift force, which is directly related to volume. We found the optimal shape of blimps by finding the blimp that had a substantial lift force, while flying relatively efficiently (and thus aerodynamically).
