The invention provides a convection-radiation coupling heating test cabin for aerodynamic thermal ground simulation test, which comprises a test section front cabin and a test section rear cabin, the test section rear cabin is arranged on the rear side of the test section front cabin and is arranged on an external vacuum cabin section, the front end of the test section front cabin is provided with a spray pipe flange, the spray pipe flange is used for installing a spray pipe, and the spray pipe is connected with the test section front cabin. A plurality of observation windows and radiation windows are uniformly arranged on the conical surface of the test section front cabin in a staggered manner; and at least two bracket adapter flanges for mounting a bracket and a feeding device for a test model are arranged on the cylindrical wall surface of the test section rear cabin. According to the invention, one convection heating device and a plurality of radiation heating devices of various types are integrated, so that high-energy convection or radiation heating caused by accidents can be effectively resisted. A plurality of various types of test model brackets and feeding devices can be mounted at the same time through the bracket adapter flange; the test section rear cabin is installed on an external vacuum cabin section so that the test model can be in a vacuum environment.
本发明提供了用于气动热地面模拟试验的对流‑辐射耦合加热试验舱,包括试验段前舱和试验段后舱,试验段后舱安装在试验段前舱的后侧,试验段后舱安装在外接的真空舱段上,试验段前舱前端设有喷管法兰,喷管法兰用于安装喷管,试验段前舱的圆锥面上均匀且交错地设置有若干观察窗和辐射窗,试验段后舱的圆柱壁面上设有不少于两个用于安装试验模型所用的支架和送进装置的支架转接法兰。本发明将一台对流加热装置和多台多种类型的辐射加热装置集成于一体,能够有效抵抗意外导致的高能对流或辐射加热。并且通过支架转接法兰能够同时安装多台、多种类型的试验模型支架和送进装置;试验段后舱安装在外接的真空舱段上能够使试验模型处于真空环境内。
