airfoil: (in aeronautics) the surface of a wing, aileron, or other structure designed to lift or control an aircraft using natural airflow.
angle: The distance (usually measured in degrees) between two intersecting lines or planes at or near the point where they intersect.
bird: A winged warm-blooded animal that first appeared during the dinosaur era. Birds are covered in feathers and give birth to their young from eggs laid in some kind of nest. Most birds fly, but throughout history there have been occasional flightless species.
colleague: A person who works with other people, colleagues, and team members.
component: Something that is part of something else, such as a component on an electronic circuit board or an ingredient in a cookie recipe.
drag: The retarding force exerted by the air or other fluid surrounding a moving object. It involves friction. However, unlike simple friction, it increases with the speed of the object.
engineer: A person who uses science and mathematics to solve problems. As a verb, “engineering” means to design a device, material, or process that solves some problem or unmet need.
flap: These devices are attached to the trailing edge of the aircraft wing. In addition to frictional drag forces, these increase the lift force on the wing (especially useful at low speeds, such as during landing).
force: External influences that can change the motion of objects, move objects closer together, or cause motions or stresses in stationary objects.
lift: An upward force exerted on an object. This can occur when an object (such as a balloon) is filled with a gas that is lighter than air. It can also occur when an area of ​​low pressure occurs above an object (such as an airplane wing).
maneuver: To place something in a desired or necessary position using one or more skilled movements or steps.
model: A simulation (usually using a computer) of a real-world event developed to predict one or more possible outcomes. Or an individual whose purpose is to show how something works or looks like to another person.
down: A term used to describe the collection of feathers that cover a bird. A single large feather is sometimes called a plume.
pressure: Force applied uniformly over the entire surface. It is measured as force per unit area.
Proceedings of the National Academy of Sciences: A prestigious journal founded in 1914 that publishes original scientific research. The journal's content spans biology, physics, and social sciences. Today, each of the more than 3,000 papers published each year is not only peer-reviewed but also approved by members of the National Academy of Sciences.
resistance: (in physics) something that prevents the free movement of a physical substance (such as a block of wood, a stream of water, air, etc.). This is usually because friction occurs to prevent that movement.
scenario: A possible (or likely) sequence of events and how they will unfold.
wind tunnel: A facility used to study the effects of air passing through solid objects. Often full-scale scale models such as airplanes and rockets are used. Objects are usually covered with sensors that measure aerodynamic forces such as lift and drag. Engineers also sometimes inject small streams of smoke into wind tunnels to visualize the flow of air past objects.
