A type of trailing-edge flap that forms a slot between its leading edge and the inside of the flap well in the wing. This slot directs fast-moving air over the lowered flap and prevents it separating from the flap upper surface. The air flowing over the top of the flap increases the lift produced by the wing when the flap is lowered.
Industry:Aviation
A type of trailing-edge wing flap used on some of the larger, high-performance airplanes. Triple-slotted flaps extend from the trailing edge of a wing in three sections. The trailing edge of one section forms a duct with the leading edge of the section behind it to force air down over the top of the flap. Triple-slotted flaps prevent the airflow from separating from the surface of the flap when they are fully extended.
Industry:Aviation
A type of training aircraft used by the French in the early stages of World War I. The engines in these aircraft were not powerful enough to produce flight, but the student was able to develop enough feel of the controls to allow an effective transition to a flyable aircraft.
Industry:Aviation
A type of transistor amplifier in which two bipolar transistors are connected in such a way that the emitter of the input transistor is connected directly to the base of the output transistor. The collectors of both transistors are connected together. A Darlington amplifier is a double emitter-follower amplifier.
Industry:Aviation
A type of transportation system using a single rail to carry the cars or other objects moved along the system. Many industrial factories use a monorail above the production line to move heavy equipment along the line.
Industry:Aviation
A type of tree that sheds its foliage at the end of the growing season. Hardwoods come from deciduous trees.
Industry:Aviation
A type of truss structure in which the longitudinal members are separated by vertical members that carry only compression loads, and diagonal members that carry only tensile loads.
Most fabric-covered airplane wings are built with a Pratt truss. The wing spars are the main structural members, the compression struts or compression ribs carry only compressive loads, and the drag and anti-drag wires carry only tensile loads.
Industry:Aviation
A type of tubing nut used to attach a piece of flared tubing to a threaded fitting. B-nuts are used with a sleeve slipped over the tubing before the tubing is flared. The B-nut forces the sleeve tight against the flare, which seals against the flare cone of the male fitting.
Industry:Aviation
A type of turbine blade with a T-shaped tip. The tips of the blades touch each other to form a ring around the turbine wheel to support the blades.
Industry:Aviation
A type of turbine engine combustor in which the air flowing from the compressor follows an S-shaped pattern and enters the combustor at its rear end. As the air flows forward through the combustor, fuel is sprayed into it and burned. The burning fuel heats and expands the air. After the hot gases leave the combustor, they complete the S-turn and flow rearward, through the turbine.
Reverse-flow combustors allow the engine to be shorter than it could be if straight-through combustors were used.
