Apparatus for mixing high and low pressure air from a jet engine

摘要

An apparatus for mixing high and low pressure air from a jet engine and introducing the air to an air duct of the air conditioning system of an aircraft. The apparatus provides a plurality of high pressure nozzles inside an air-mixing chamber. By controlling the opening and closing of the nozzles individually, a stepped area ratio of high pressure air with low pressure air is provided for regulating the temperature of the mixed air to the air conditioning system of the aircraft while the aircraft is taking-off, climbing, cruising at various altitudes and landing.
