The utility model discloses a compound environmental test of temperature - acceleration is with light hot loading device, including radome fairing, electric heating film and fan that one end opening and the other end are remained silent, the radome fairing passes through the main part bolt to be connected with centrifugal horn, and in the testpieces was installed on centrifugal horn through the mesa and is placed the inner space of radome fairing in, in the radome fairing, the insulating layer was placed in between outer wall and the inner wall, and a plurality of electric heating film evenly paste and adorn on the inner wall, and the position that is close to bottom center in it in the inner wall and its are installed to the fan, and to blow orientation just central to the interior bottom of inner wall. The utility model discloses a structure that electric heating film pasted the dress realizes the heating, can realize temperature control and add the purpose that speed control can go on in step, has promoted the compound environmental test's of temperature - acceleration analog capability, adopt three layer construction's radome fairing, reduced whole quality, improved the heat preservation effect, through set up the fan inside the radome fairing, the homogeneity of temperature and the heat convection efficiency of heating source have been improved.
