中文摘要：
建立大型壳体结构轴向非分段式高温热试验装置。设计直径为14 mm、长度为2.25 m，长度/直径比接近160的超长大功率石英灯加热器，并使用自行研制的大功率可调式供电装置，提高单区域大面积加热源的调控能力，实现2.1 m的大型壳体结构单区域整体连续加热试验研究。该方法有效提高了大型壳体结构内壁试验温度分布的均匀性和真实性，为研制大型高速航天飞行器提供更加良好的高温热环境试验手段。
英文摘要：
In this paper, a non-segmental test apparatus was established for high temperature thermal test along the axial direction of large shell structures. The extra long, high power quartz lamp heaters, whose ratio of the diameter （14mm） to the length （2.1m） was nearly 160, were designed for the test, and a self-developed high-power adjustable power supply device was utilized to improve the control capability of the single, large area heating. Using this apparatus, a 2.1m long, non-segmental, continuous heating experiment for a single area of the large shell structure was successfully performed. This heating manner efficiently enhances the uniformity and the authenticity of the inner wall temperatures distribution of the large structures in the thermal test, and also provides an excellent high temperature thermal environment experimental technique for the design of large, high-speed aerospace vehicles.
