High School Aerodynamics & Hydrodynamics Science Projects (7 results)

You've seen for yourself, or in videos, planes flying, rockets hurdling towards space, boats racing through the water and submarines exploring the depths of the ocean. Have you ever stopped and thought about the aerodynamics and hydrodynamics involved in their operation? There is a lot of interesting science that goes into how they work! Check out these science and engineering projects to explore movement through air and water.

Does the force of drag have an effect on the distance the puck will travel? Think of a way to launch the puck with a reproducible force, and examine the effect of launching the puck in different orientations on the distance it travels. For more information on the physics, see Haché, 2002. Read more

Helicopters are fascinating to watch. The spinning rotor blades on top of the helicopter generate lift, allowing it to take off vertically. They can land vertically, too, allowing them to set down in small spaces, such as hospital helipads or on a ship at sea. In this aerodynamics science fair project, you will fly a remote-controlled helicopter and measure how the rate of the rotor's rotation changes as the helicopter hovers and flies up or down.

Science Fair Project Idea
A technique often used in wind tunnels is to introduce smoke in front of the airfoil that is being tested. The smoke comes from regularly-spaced point sources, and the wind flow in the tunnel spreads it out into parallel lines, called streamlines. The streamlines make it possible to visualize the airflow over the airfoil. When the lines continue smoothly over and past the airflow, they show that the flow remains laminar, and that the airfoil is creating very little drag. When the… Read more
