Aerodynamics & Hydrodynamics Science Projects (49 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!

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.

Have you ever flown in an airplane, or looked up at one flying in the sky, and wondered how such a massive machine can stay in the air? Airplanes can stay in the air because their wings, also referred to as airfoils, generate lift. Engineers use devices called wind tunnels to experiment and test different wing shapes when they design new airplanes. Wind tunnels let engineers make careful measurements of the air flow around the wing, and measure the amount of lift it generates.
If you can get…

Try different wind turbine/propeller (chord length, pitch) designs by making models from balsa wood. Connect the spinning axle to a DC motor and measure the voltage produced across a resistor to measure power output. Use fan as wind source. (Judge, 2004)

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.

If you have an air hockey table, you know that the puck floats on a thin cushion of air when the table is turned on. With little friction, the puck can travel very fast. How much lift force is created by the air? Add small amounts of weight to the puck and see when it no longer floats to measure the lift force. How many air holes (on average) support the puck? How much force is generated by each air hole? Will a puck with a larger surface area, supported by more air holes (on average),…

You have probably made plenty of regular paper airplanes simply by folding a piece of printer or notebook paper. Have you ever tried making a "high performance" paper glider? These gliders use a different construction technique that involves cutting multiple shapes out of thicker, stiffer paper and gluing them together (this process is called lamination). There are many resources online that can get you started with the art of making high performance paper gliders. See the references in the…

If you've played catch with both Aerobie flying rings and Frisbees, you know that the rings fly much further than the Frisbees with the same throwing effort. Why is that? Investigate the aerodynamics of flying rings and flying disks and find out!

Have you ever noticed how some jet planes have small, vertical projections as the tips of the wings? They're called winglets. What are they there for?

You can measure the viscosity of a fluid using a glass tube and a marble with slightly smaller diameter than the tube. Seal one end of the tube. Fill the tube with the fluid to be tested. Drop the marble into to the tube and measure the time it takes to fall a fixed distance. Repeat the measurement several times, and use the average value. How does viscosity change with the amount of sugar dissolved in water? How does viscosity change with temperature?
