• Cabin pressurization — is the active pumping of compressed air into an aircraft cabin when flying at altitude to maintain a safe and comfortable environment for crew and passengers in the low outside atmospheric pressure.Pressurization is essential over 3,000 m (10,000 …   Wikipedia

• cabin pressurization safety valve — A combination pressure and vacuum valve meant to prevent cabin pressurization from exceeding safe limits. The valve normally combines the functions of overpressure relief valve, vacuum relief valve, and dump valve. The overpressure relief valve… …   Aviation dictionary

• Pressurization — generally refers to the application of pressure in a given situation or environment; and more specifically refers to the process by which atmospheric pressure is maintained in an isolated or semi isolated atmospheric environment (for instance, in …   Wikipedia

• pressurization — i. A form of climate control of an aircraft. It is a means of increasing the partial pressure of oxygen in the cabin of an aircraft flying at a high altitude by increasing the air pressure in the cabin to that of an altitude that requires no… …   Aviation dictionary

• compressor bleed air — Air taken out of the compressor section of a gas turbine engine to prevent compressor stall and operate cabin pressurization and air conditioning systems. Air may also be bled from the compressor for boundary layer control …   Aviation dictionary

• air bleed — i. A small hole in the fuel passage between the float bowl and the discharge nozzle of a float carburetor. This air bleed provides a more even mixture over a wide range of airflows to improve atomizing the fuel and reduces the size of the fuel… …   Aviation dictionary

• Bleed air — in gas turbine engines is compressed air taken from within the engine, after the compressor stage(s) and before the fuel is injected in the burners. While in theory bleed air could be drawn in any gas turbine engine, its usage is generally… …   Wikipedia

• differential pressure range of pressurization — The range of cabin pressurization in which a constant differential is maintained between the cabin pressure and the outside air pressure. This method of pressurization is used after the cabin reaches its maximum allowable differential pressure …   Aviation dictionary

• Compressed air — is air which is kept under a certain pressure, usually greater than that of the atmosphere. In Europe, 10 percent of all electricity used by industry is used to produce compressed air, amounting to 80 terawatt hours consumption per year.[1][2]… …   Wikipedia

• Aircraft cabin — An aircraft cabin is the section of an aircraft in which passengers travel, often just called the cabin. At cruising altitudes, the surrounding atmosphere is too thin to breathe without an oxygen mask, so cabin pressurization adapts the cabin to… …   Wikipedia

• delivery air duct — An isolation valve at the discharged side of the air turbine that prevents the loss of cabin pressurization through a disengaged cabin air compressor …   Aviation dictionary
