The distance traveled by light in one year. The light year is a unit of measurement commonly used in discussing astronomy and is equal to 5.879 trillion (5.879 x 1012 miles).
Industry:Aviation
The distance, measured in inches, between the center line of the propeller shaft and a location along the blade of a propeller.
Blade station measurements are used to identify locations along the blade of a propeller.
Industry:Aviation
The distortion of the magnetic flux between the field poles in an electric generator or motor caused by the magnetic field produced by current flowing in the winding of the armature.
Industry:Aviation
The disturbed air left behind an airplane. At one time, it was thought that the rough air behind and below an airplane in flight was caused by the propeller slipstream. But this turbulence is actually caused by air spilling over the wing tips and forming tornado-like vortices.
Wake turbulence also includes thrust stream turbulence, jet blast, jet wash, propeller wash, and rotor wash, both on the ground and in the air.
Industry:Aviation
The division between the troposphere, the lower level of the earth’s atmosphere, and the stratosphere, the layer of the atmosphere above the troposphere.
Industry:Aviation
The division within the Department of Transportation of the United States government that has the responsibility of promoting safety in the air, by both regulation and education. Aircraft and the airmen who operate them are licensed by the FAA, and the FAA maintains the airways along which the aircraft fly. The FAA is headed by a civilian, the Administrator of Federal Aviation.
Industry:Aviation
The dominant west-to-east motion of the atmosphere, centered over the middle latitudes of both hemispheres.
Industry:Aviation
The downslope of airplane wings, or the downward angle formed between the wings and the lateral axis of an airplane. Negative dihedral, also called cathedral, increases the maneuverability of the airplane while decreasing its lateral stability.
Industry:Aviation
The downward aerodynamic force produced by the horizontal tail surfaces of an airplane. Tail load normally acts downward to give the airplane longitudinal stability. The lift produced by the wing of the airplane must overcome the downward-acting tail load, as well as the downward-acting force caused by the weight of the airplane.
Industry:Aviation
The drawing or pattern used to cut a piece of sheet metal. The layout includes marks to locate all of the bend tangent lines and the center marks for all of the holes to be drilled.
