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.
