Abstract

The invention relates to the technical field of ventilation devices, and concretely relates to a ventilation device for an aircraft test. The device comprises a plurality of groups of sub-circulating air treatment systems; and each group of sub-circulating air treatment system comprises an air return system, a temperature treatment system connected with the air return system and used for adjusting air, an air supply system connected with the temperature treatment system and used for conveying the adjusted air, and a humidity treatment system used for adjusting humidity. The overall structural design is reasonable, the extreme environment air circulation treatment problem of a large aviation aircraft climate laboratory can be effectively solved through the multiple sets of sub-circulation air treatment systems, the laboratory can be divided into multiple areas in a layout division mode, and then the multi-area airflow organization partition adjustment is conducted, so that the temperature field, the humidity field and the velocity field meet test requirements of different environments.

Description

technical field [0001] The invention relates to the technical field of ventilation devices, in particular to a ventilation device for aircraft testing. Background technique [0002] As one of the essential links in aircraft design, the aircraft climate environment adaptability test is to let the aircraft experience the stress of the climate environment under the indoor simulation or the natural climate environment conditions outside the field, so as to obtain the information of the extreme ability of the aircraft to withstand the climate environment, and According to the development requirements, failure criteria and test data, a comprehensive evaluation of its climatic environment adaptability is carried out to determine the degree to which its climatic environment adaptability meets the requirements. [0003] One of the essential factors for carrying out the aircraft climate environment adaptability test is the construction of a large-scale aviation aircraft climate labora...
