摘要: 高温风洞是开展飞行器热防护技术研究的重要试验设备。为满足在高温风洞前端长时间生成大尺度、高焓、高速气流的试验需求,提出了一种基于气氧/煤油燃烧的高温流场生成装置。装置采用火炬式点火器点火启动,通过使用气液同轴离心喷嘴以及分区隔板的喷注器进行燃烧组织,并由可替换的型面射流喷管实现大尺度均匀流场的生成。30kg/s量级加热装置千秒热试车调试结果表明,该装置能够实现快速点火并长时间维持大尺度稳定流场的生成,在飞行器热防护地面试验技术领域将有良好的应用前景。

Abstract: The high-temperature wind tunnel is an important test equipment for the research of aircraft thermal protection technology. In order to meet the test requirements for generating large-scale, high-temperature and high-speed airflow at the front of high-temperature wind tunnel, a high-temperature airflow generating device based on gas-oxygen/kerosene combustion was proposed. The device was ignited by a torch igniter, and the combustion organization was performed by using a combustion partition plate and several gas-liquid coaxial centrifugal injectors, and a large-scale uniform airflow field was generated by a replaceable profile jet nozzle. The hot test of the device with the mass flow rate of 30kg/s lasted for one thousand seconds. The test results show that the device can realize rapid ignition and maintain the generation of large-scale stable airflow field for a long time. This device has a good application prospect in the field of aircraft thermal protection ground test technology.
