A small movable control mounted on a primary control surface. The trim tab is adjustable in flight to change the aerodynamic load on the control surface. The aerodynamic load produced by the trim tab deflects the control surface enough for it to trim the aircraft for hands-off flight at any normal speed.
Industry:Aviation
A small movable tab built into the trailing edge of an aircraft primary control surface. A servo tab is actuated by the cockpit control, and it moves in the direction opposite to the direction the primary surface is to move. The servo tab produces an aerodynamic force that moves the surface on which it is mounted.
Industry:Aviation
A small nozzle which directs a stream of lubricating oil to a specific point to be lubricated. Oil jets are used to direct oil to bearings and gears.
Industry:Aviation
A small offset near the edge of a piece of sheet metal. It allows one sheet of metal to overlap another sheet while maintaining a flush surface.
Industry:Aviation
A small parachute attached to the canopy of the main parachute and used to pull it from the pack, so it can open.
Industry:Aviation
A small parachute attached to the rear of an airplane structure. The drag chute can be deployed (opened) after the airplane touches down on landing to help it slow down.
Industry:Aviation
A small particle of solar matter that is visible only as it becomes incandescent (glows because of its extremely high temperature). The high temperature is caused by friction as the meteor falls through the earth’s atmosphere.
Meteors are made of metal or rock or a combination of metal and rock. They are often called “shooting stars” or “falling stars,” and millions of burned-out particles of meteors fall on the earth each day as dust.
Industry:Aviation
A small permanent magnet used in some electrical indicating instruments to pull the instrument pointer off the scale when the instrument is not energized.
Industry:Aviation
A small piece of alkaline metal placed inside an electron tube (vacuum tube) when it is manufactured. When the tube is completed and the air evacuated from it, current is passed through the getter which raises its temperature enough to melt it, causing it to react with any oxygen left inside the tube. The silvery deposit often seen inside the glass tube envelope is the residue from the getter.
Industry:Aviation
A small pin-type fastener, used to fasten pieces of sheet metal together. Most aircraft rivets are made of aluminum alloy and are driven cold. The rivet is slipped through holes in the material being fastened, and a heavy steel bucking bar is held against the end of the shank. The head of the rivet is hammered with a rivet gun (an air hammer). The bucked head, or shop head, that is formed when the rivet is driven, is flat on top, and its sides are rounded.
