Movable thermal environment device for ground thermal protection and insulation test of aerospace vehicle

Abstract

The invention relates to a movable thermal environment device for a ground thermal protection and insulation test of an aerospace vehicle, and aims at solving a problem that the closure and evacuationof a thermal environment device can interfere with an engine nozzle in the prior art. The device comprises a control system, a base, four high-temperature heating infrared lamp arrays and six translation platform modules, wherein the six translation platform modules are respectively a front cone section left module, a front cone section right module, a tail end left module, a tail end right module, an axial left module and an axial right module, and the six translation platform modules all adopt a motor driven ball screw and a transmission structure matched with a linear guide rail; the fourhigh-temperature heating infrared lamp arrays comprise a front cone section left lamp array, a front cone section right lamp array, a tail end left lamp array and a tail end right lamp array; and thefour high-temperature heating infrared lamp arrays are closed and evacuated through the six translation platform modules.

Description

technical field [0001] The invention relates to an aerospace vehicle ground heat insulation test device, in particular to a mobile thermal environment device for an aerospace vehicle ground heat insulation test. Background technique [0002] The separation and heat insulation test process of the aerospace vehicle cabin is as follows: firstly, the heat insulation joint assessment test is carried out on the mobile test platform. Separation, so as to carry out the next step of compartment separation drop test. Since the four engine nozzles of the whole product are all arranged outside the cabin, in order to prevent the thermal environment device from interfering with the four engine nozzles, higher requirements are put forward for the closure and evacuation of the thermal environment device , the thermal environment device must not only have the function of automatically approaching the orbit control cabin and automatically moving away from the orbit control cabin, but also st...
