- Air Film Coefficient. Air Film Coefficient is a method to account for the heat transfer of the thin layer of still air on the surface of structure. This thin layer or Air Film has some thermal resistance. The Air Film Coefficient is a number used in calculating the heat transfer through a structure. There is a coefficient for the outside and inside surface.

What Is Aerodynamics? Aerodynamics is the study of how gases interact with moving bodies. Because the gas that we encounter most is air, aerodynamics is primarily concerned with the forces of drag and lift, which are caused by air passing over and around solid bodies.hen the airplane is in level flight at a constant speed, the force of the thrust is just enough to counteract the aerodynamic drag. Moving air can also generate forces in a different direction from the flow. The force that keeps an airplane from falling is called lift. Lift is generated by an aircraft wing.

- The fuselage, or body of the airplane, is a long hollow tube which holds all the pieces of an airplane together. The fuselage is hollow to reduce weight. As with most other parts of the airplane, the shape of the fuselage is normally determined by the mission of the aircraft.

- Welcome to the Beginner's Guide to Aerodynamics. What is aerodynamics? The word comes from two Greek words: aerios, concerning the air, and dynamis, which means force. Aerodynamics is the study of forces and the resulting motion of objects through the air.

- Tailplane - The flying surface at the aft or tail section of an aircraft used with horizontal or vertical to describe the axis of control or stability. Thickness- Used to describe the total frontal area of an airfoil and generally represented as a percentage of the chord for a given airfoil or wing section.

The Physics of Flight Bernoulli's principle. Objects that fly using wings get their lift by taking advantage of Bernoulli's principle. Bernoulli's principle says that as a fluid's velocity increases its pressure decreases. Airplanes and birds have an airfoil shape to each of their wings to produce lift. The airfoil shape produces unequal lengths across the top and bottom of the wing. Air splitting at the front of the wing must rejoin at the back of the wing so as not to create a vacuum. Since the top surface is curved upward and is longer it forces the air to move faster across the top than the bottom.

Airplane Airplane, also called aeroplane or plane, any of a class of fixed-wing aircraft that is heavier than air, propelled by a screw propeller or a high-velocity jet, and supported by the dynamic reaction of the air against its wings. For an account of the development of the airplane and the advent of civil aviation see history of flight.

- + Contact Glenn. This slide gives technical definitions of a wing's geometry, which is one of the chief factors affecting airplane lift and drag. The terminology is used throughout the airplane industry and is also found in the FoilSim interactive airfoil simulation program developed here at NASA Glenn. Actual aircraft wings are complex three-dimensional objects, but we will start with some simple definitions.

Kite A kite is a tethered object with surfaces that react with a fluid (water, air, gas, plasma) to create lift and drag; often the result is flying in air or water of the wing parts of a kite. A kite consists of wings, tethers, and anchors. A kite may be with fixed or moving anchors. There are natural and synthetic kites.

Glossary of Terms Aerodynamic drag. Drag produced by a moving object as it displaces the air in its path. Aerodynamic drag is a force usually measured in pounds; it increases in proportion to the object's frontal area, its drag coefficient, and the square of its speed. Air Dam.

Learn About Aircraft Stall and How to Prevent It An aircraft stall is an aerodynamic condition in which an airplane exceeds its given critical angle of attack and is no longer able to produce the required lift for normal flight.This type of stall should not be confused with an engine stall.In an airplane, a stall has nothing to do with the engine, and is only defined as the aerodynamic loss of lift that occurs when an airfoil (i.e., the wing of the airplane) exceeds its critical angle of attack.Angle of Attack.n an airplane, a stall has nothing to do with the engine, and is only defined as the aerodynamic loss of lift that occurs when an airfoil (i.e., the wing of the airplane) exceeds its critical angle of attack.

airfoil Such a wing, with an infinite span perpendicular to the page, is called an infinite wing. The aerodynamic force on the airfoil, by definition, is the force exerted on a unit span of the infinite wing. For this reason, airfoil data are frequently identified as infinite wing data.

Air mass In meteorology, an air mass is a volume of air defined by its temperature and water vapor content.Air masses cover many hundreds or thousands of square miles, and adopt the characteristics of the surface below them. weather front is a boundary separating two masses of air of different densities, and is the principal cause of meteorological phenomena. In surface weather analyses, fronts are depicted using various colored lines and symbols, depending on the type of front.

- Last update 9/15/2010 what's new. Frequently, the question arises as to what airfoil or airfoils were used in the wing design of a particular aircraft. Jane's All The World's Aircraft has been a good source of this information, but in many cases (particularly military aircraft) it doesn't list this information.
