lobe: (in aeronautics) The surface of a wing, aileron, or other structure that’s designed to help in lifting or controlling an aircraft by use of natural air currents.
corner: The space (often measured in degrees) between two intersecting lines or surfaces at or near their point of contact.
birds: Warm-blooded animals with wings that first appeared throughout the time of the dinosaurs. The birds are covered with feathers and provides birth to young from eggs, which they lay in a nest. Most birds fly, but throughout history there have been species that didn’t.
colleague from work: Someone who cooperates with one other; co-worker or team member.
Hi: Something that is a component of something else (e.g. components that go on a circuit board or ingredients that go right into a cookie recipe).
Pull: The decelerating force exerted by the air or other fluid surrounding a moving object. It involves friction. However, unlike normal friction, it increases with the speed of the item.
engineer: A one that uses science and arithmetic to resolve problems. As a verb, engineering means the design of a tool, material, or process that can solve some problem or unmet need.
flaps: These devices are attached to the trailing fringe of an aircraft’s wing. In addition to the drag force, friction increases the lift force of the wing (which can be particularly useful at low speeds, e.g. during landing).
force: some external influence that can change the motion of an object, hold objects close together, or cause motion or stress in a stationary object.
elevator: An upward force acting on an object. This can occur when an object (equivalent to a balloon) is stuffed with a gas that weighs lower than air; it can also occur when an area of low pressure appears over an object (e.g. an airplane wing).
maneuver: To bring something right into a desired or obligatory position by a number of skillful movements or procedures.
model: A simulation of a real-world event (often using a pc) that’s designed to predict a number of likely outcomes. Or a one that is there to point out how something would work or look to others.
plumage: A term used to explain the gathering of feathers that cover a bird. A single large feather could also be called a plume.
pressure: Force applied uniformly on a surface, measured as force per unit area.
: A prestigious journal publishing original scientific research begun in 1914. The journal’s content covers biological, physical and social sciences. Each of the greater than 3,000 articles currently published annually isn’t only peer-reviewed but in addition approved by a member of the United States National Academy of Sciences.
resistance: (in physics) Something that forestalls a physical material (equivalent to a block of wood, the flow of water, or air from moving freely), actually because it provides friction that impedes its movement.
scenario: Possible (or probable) sequence of events and their course.
wind tunnel: An object used to check the consequences of air flowing past solid objects, which are sometimes scale models of real-size objects equivalent to airplanes and rockets. Objects are typically covered with sensors that measure aerodynamic forces equivalent to lift and drag. Sometimes engineers blow tiny streams of smoke into the wind tunnel, making the airflow visible past the item.
