Cabin Atmosphere Control System Flashcards
What is a method used by some turbine powered aircraft for pressurization?
bleed air
What are some methods of supplying heat to the cabin on a reciprocating powered aircraft?
exhaust shroud, janitrol heater
How does continuous flow oxygen system operate?
pressure fed, candle
What type of oxygen must be used in aircraft?
aviators breathing oxygen
What are two groups of independent cabin pressurization?
air cycle, turbocharger
What is the principle control of a pressurization system?
cabin altitude controller
What is a Roots-type blower?
gear driven blower
What pressurization control unit will change position of an outflow valve?
cabin pressure controller (regulator)
What is the function of ventilating air in a combustion heater?
sends warm air into the cabin via blower or ram air
What are sources of ventilating air in a combustion heater?
ram air or fan
What components are used in an air-cycle cooling system?
air to air heat exchanger, ducting, water separator, mixing plenum
What causes temperature drop in an air cycle cooling system?
expansion turbine
How does a water separator remove moisture from the air?
by swirling the air which slings the water outward
What is vapor-cycle cooling?
removing the heat from the air
What components are in a vapor cycle cooling system?
refrigerant, dryer, expansion valve, evaporator, compressor, condenser, blower
