Problems solved by technology

[0007] In addition, during the descent or idle phase, the bleed air pressure from the air source system is low, which cannot meet the working requirements of the inerting system
If an air turbine compressor is used, additional bleed air is required to drive the turbine, thus increasing the amount of bleed air and fuel consumption of the engine
[0008] This creates a burden on system installation space and system weight, and may affect the aerodynamic performance of the aircraft

Abstract

The invention discloses an air preparation system, which comprises an air inlet, an air outlet, a compression device and a main refrigeration device, wherein the air inlet is used for introducing airinto the air preparation system; the air outlet is used for sending the air processed by the air preparation system out of the air preparation system; the compression device is arranged between the air inlet and the air outlet and is in fluid communication with the air inlet and the air outlet; the compression device causes the air which flows through the compression device to be pressurized; themain refrigeration device is arranged between the compression device and the air outlet and is in fluid communication with the compression device and the air outlet; the main refrigeration device enables the temperature of the air which flows through the main refrigeration device to be lowered; the compression device is subjected to energy supply by electricity; and in addition, the main refrigeration device is a heat exchange element subjected to the energy supply by electricity. According to the air preparation system disclosed by the invention, the air entraining flow, the installation system and the weight of the system can be reduced.

Description

technical field [0001] The invention relates to an aircraft air preparation system, in particular, the invention belongs to the field of aircraft inerting system design. Background technique [0002] The air preparation system of civil aircraft is a subsystem of the on-board nitrogen generation system in the fuel inerting system. state. [0003] The air preparation system of existing aircraft is generally made up of parts such as pressure adjustment valve, heat exchanger, temperature control valve, pressure sensor, temperature sensor and controller. [0004] In the Chinese invention patent application CN105936338 A submitted by Hamilton Sundstrand Company on March 4, 2016, a method of using an air turbine compressor to boost the bleed air and using a double heat exchanger to adjust the bleed air temperature is disclosed. Regulated air preparation system. [0005] It can be known from the above description of the prior art that the air preparation system in the prior art u...
