DIAPHRAGM
IRIS, flexible management mechanism of the valve by the pressure.
DIFFERENTIAL PRESSURE
Differential pressure, the pressure difference relative to each other in one and the same system as measured in pounds per square inch (psid).
DIFFUSER
Diffuser of the engine between the compressor and the combustion chamber for lowering the airflow rate and increasing the air pressure.
DIGITAL
DIGITAL, the number refers to a signal whose amplitude remains constant for a limited period of time limit. The digital signals are typically represented as a series of high and low pulses.
DIGITAL-TO-ANALOG
Analog to digital conversion process of the digital signal (binary) in a time-varying variable (analog) signal, which is in a close approximation of the actual signal.
DIHEDRAL
ANGLE V, the angle between the line of the aerodynamic wing in a plane and the line of the water level.
DILUTER DEMAND REGULATOR
REGULATOR REQUIRED liquefaction component crew oxygen system, which mixes air and oxygen and provides a constant pressure of oxygen even if there is a change in air pressure of the cabin.
