Abstract

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 access to a wind tunnel or build your own using the Science Buddies How to Build and Use a Subsonic Wind Tunnel tutorial, then you can do a science project where you measure the lift generated by different types of airfoils. You will need to do a lot of background research about aerodynamics and the terminology involved, and you will probably need help from an adult if you are going to build your own wind tunnel. Can you compare different wing designs and find out which one generates the most lift?

Variations

  • If building a wind tunnel is not an option for you, it doesn't mean that you can't do an aerodynamics project. For example, kites are a great way to learn about aerodynamics. The Wright brothers used kites to test many of their design ideas for their airplane. For more information, see: The Wright Stuff: Using Kites to Study Aerodynamics.

Aviation Inspector

Aviation inspectors are critical to ensuring that aircraft are safe to fly. They conduct pre-flight inspections to make sure an aircraft is safe. They also inspect the work of aircraft mechanics, and keep detailed records of work done to maintain or repair an aircraft. As problems are identified, they may make changes to maintenance schedules, and may be called upon to investigate air accidents. Read more

Aerospace Engineering & Operations Technician

Aerospace engineering and operations technicians are essential to the development of new aircraft and space vehicles. They build, test, and maintain parts for air and spacecraft, and assemble, test, and maintain the vehicles as well. They are key members of a flight readiness team, preparing space vehicles for launch in clean rooms, and on the launch pad. They also help troubleshoot launch or flight failures by testing suspect parts. Read more

Pilot

Pilots fly airplanes, helicopters, and other aircraft to accomplish a variety of tasks. While the primary job of most pilots is to fly people and cargo from place to place, 20 percent of all pilots have more specialized jobs, like dropping fire retardant, seeds, or pesticides from the air, or helping law enforcement rescue and transport accident victims, and capture criminals. Pilots enjoy working and helping people in the "third dimension." Read more
