This activity, created specially for classroom use, teaches how the force of lift affects an object moving through the air. Students will construct an indoor paper box kite using the template provided and use it to conduct an experiment.
This activity, created specially for classroom use, teaches how the force of weight affects an object moving through the air. Students will construct a small parachute using the template provided and use it to conduct an experiment.
When flying a catapult glider, it is useful to know how to increase the sink rate of your glider, so that it will fly for a longer period of time. In this article, Kurt Krempetz of AMA Glider discusses various theories regarding the launching heights and sink rates of catapult gliders.
Washout is usually thought of as twisting, shaping/sanding or adding an up tab to the trailing edge of the tips of a wing, so wing tips are at a negative angle of attack, compared to the root of the wing. Kurt Krempetz of AMA Glider describes the two methods that are typically used in glider designs to add washout to a wing.
Although indoor glider events are simple, they are sometimes hard to master. Weight, strength, and aerodynamics are three issues that are very important when flying an indoor glider. Kurt Krempetz for AMA Glider will discuss these issues in this article.
Learning how to launch handles for catapult gliders is essential when flying a glider. Kurt Krempetz of AMA Glider discusses the AMA rules for launching handles for catapult gliders in both indoor and outdoor events are discussed.
Kurt Krempetz of AMA Glider explains why it is important to trim a glider, so that it will be able to make turns while flying, rather than just flying straight. He also discusses the various forces of a glider, such as the lift force and gravity, and the pitch axis.
Control Line (CL) model aviation can trace its roots back to the early tethered experiments of Victor Tatin, whose compressed-air powered model was flown round-the-pole in 1879. In the 1920s and 1930s aeromodelers began to take this a step further and actually try and control their whip and powered aircraft in flight. Learn more here!
