A screw-type clamp made in the shape of the letter C. One jaw is fixed, and the other is mounted on a screw.
Industry:Aviation
A scum inside the fuel tanks of turbine-engine-powered aircraft caused by micro-organisms that feed on the fuel and live in water that has condensed from the fuel. This scum clogs fuel filters, lines, and fuel controls and holds water in contact with the aluminum alloy fuel tank structure causing severe corrosion.
Industry:Aviation
A seal around a rotating shaft, used to keep air from passing out of the housing holding the shaft. Air seals are often made of thin alternate fixed and rotating blades which act as air dams to prevent air flowing past the seal.
Industry:Aviation
A seal between two stationary objects. A gasket is usually made of a soft material so it can conform to the surfaces of the two parts and form a leakproof seal. A gasket is similar to a packing, except a packing is used when there is relative motion between the parts being sealed.
Industry:Aviation
A seal used between surfaces in which there is relative movement. When there is no movement between the surfaces, a gasket is used to provide the seal.
Industry:Aviation
A sealed mechanical refrigeration system used to lower the temperature of the air in an aircraft cabin. A liquid refrigerant, such as R-12 or R-134a, is sprayed into the evaporator coils, and as it evaporates, it absorbs heat from the cabin air blown across the evaporator.
The refrigerant, now in its vapor form, flows from the evaporator into a mechanical compressor where it is compressed, increasing both its temperature and pressure. The hot, high-pressure vapor flows from the compressor through the coils of a radiator-like condenser. Air from outside the aircraft blowing across the condenser coils absorbs heat from the refrigerant vapor, causing it to change back into a liquid. The liquid refrigerant now repeats its cycle through the evaporator and picks up more heat.
Industry:Aviation
A sealed recording instrument installed in transport aircraft that makes a continuous record of the flight altitude, airspeed, heading, accelerations, and voices and noises heard on the flight deck.
The flight recorder, called a “black box,” is installed in a fireproof housing and is mounted in the tail of the aircraft where it is least likely to be destroyed in a crash.
Industry:Aviation
A second finger installed on the rotor of some aircraft magneto distributors. High voltage from an induction vibrator flows to the spark plugs through the trailing finger to produce a hot and late spark in the cylinder when the engine is being started.
Industry:Aviation
A secondary control on an airplane that allows the airplane to fly at a high angle of attack without stalling. A slat is a section of the leading edge of the wing mounted on curved tracks. These tracks move into and out of the wing on rollers. In flight at low angles of attack, the air pressure on the wing holds the slat in, and it forms the leading edge of the wing. At a high angle of attack, aerodynamic forces pull the slat forward on its tracks, and it forms a duct that forces the air down onto the top of the wing to keep it from stalling.
Industry:Aviation
A section of an aircraft factory set aside for research and development of new aircraft. No one is allowed to visit the skunk works except those who are actually involved in the project being developed there.
