Controls in an aircraft operated by a boost system. Cockpit controls move the control surfaces, but aerodynamic forces on the control surfaces cannot feed back into the cockpit controls.
Industry:Aviation
Controls that modify the effect of the ailerons, rudder, and elevators of an airplane, and do not in themselves cause rotation of the airplane about any of its three axes. Wing flaps, trim tabs, servo tabs, spring tabs, and antiservo tabs are examples of secondary controls.
Industry:Aviation
Controls used on some swept wing airplanes that serve as both ailerons and wing flaps. The flaperons on both wings can be lowered together to increase the lift and drag of the wings. This is the flap function. The flaperons can also be moved differentially: one moves up, while the other moves down. This is the aileron function.
Industry:Aviation
Copper wire covered with a thin coating of tin or solder, an alloy of tin and lead. The tin coating keeps copper from corroding and makes it easy to solder the wires.
Industry:Aviation
Copper wire that has not been annealed after it was formed by pulling it through dies. Pulling the wire through dies reduces its diameter to the desired size. It also work hardens the wire and increases its tensile strength.
Industry:Aviation
Correctly meshing the gears and adjusting the breaker point clearance in an aircraft magneto so the breaker points begin to open when the rotating magnet is in the correct position relative to the pole shoes, in its E-gap position. When a magneto is correctly timed internally, it produces the hottest spark.
Industry:Aviation
Corrosion that forms between the lap joints of metal and under labeling tape, tabs or placards that trap and hold moisture. Moisture on the surface of the metal absorbs oxygen from the air, and the extra oxygen causes the water to attract electrons from the metal to form negative hydroxide ions. Moisture trapped in the lap joints does not have any extra oxygen and therefore does not form any negative ions.
Since the metal in the lap joints has not given up any electrons, it is more negative than the metal around it, and it becomes the anode in a corrosion cell and forms a salt of the metal — it corrodes.
Industry:Aviation
Corrosion that forms on the surface of a piece of metal covered with some form of electrolyte. Surface corrosion shows up as pits filled with a powdery salt.
Industry:Aviation
Corrosion that forms where two different types of metals are in contact with each other. The severity of the corrosion is determined by the relative location of the metals in the electrochemical series.
Industry:Aviation
Corrosion that results from a concentration of metallic ions in the electrolyte. The area of high concentration of metallic ions is the cathode of the cell.
