A navigational instrument that determines direction relative to the stars. Astrocompasses are not affected by the errors inherent in magnetic compasses and gyrocompasses.
Industry:Aviation
A navigational instrument used in an aircraft when it is being navigated by dead reckoning. The drift sight measures the angle between the direction the aircraft is pointed and the direction it is moving over the ground.
Industry:Aviation
A necked-down section of an engine-driven pump shaft designed to shear if the pump should seize. When the shear section breaks, the drive can continue to turn without causing further damage to the pump or the engine.
Industry:Aviation
A negative ion that moves toward the anode (the positive electrode) in the process of electrolysis.
Industry:Aviation
A network of resistors used to decrease the amplitude of an electrical signal without causing any phase shift or frequency distortion.
Industry:Aviation
A noise heard in a gas turbine engine caused by unstable airflow in the engine. The chugging noise is produced by a mild compressor stall.
Industry:Aviation
A noise suppressor used with a gas turbine engine. A jet silencer does not actually silence a jet engine; rather, it converts some of the low-frequency vibrations into higher frequency vibrations that are more easily dissipated as they mix with the surrounding air.
Industry:Aviation
A nonelectrolytic capacitor that uses strips of metal foil as the plates and Mylar film as the dielectric.
Industry:Aviation
A nonferrous alloy of cobalt, chromium, and tungsten. Stellite is hard, wear- and corrosion-resistant, and does not soften until its temperature is extremely high. Stellite is welded to the face of many reciprocating engine exhaust valves that operate at very high temperatures.
Industry:Aviation
A noninductive, high-power resistor that can be connected to a transmission line in place of the antenna. The transmitter can be operated into the dummy load without transmitting any signal.
