Tackle the problem of designing a model rocket that carries a miniature video camera to 500 feet and then returns safely to earth by parachute. In this lesson, focus on selecting an off-the-shelf model rocket engine that can do the job. Use the impulse-momentum principle and thrust curves for various engines to predict your rocket's maximum altitude.

Description
Put together your model rocket, paying special attention to the engine mount and fins, then giving the completed vehicle a drag-reducing finish. Apply the science of aerodynamics to calculate the required diameter of the parachute. Then check the rocket's stability by determining its center of gravity and center of pressure locations. Your creation is now ready to fly.
