Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] The invention provides a quartz window installation device for a structure thermal noise test system, the installation device is as figure 1 As shown, it is used to install the quartz window 2 on the traveling wave tube 1, mainly including: a bracket 3, a thermal insulation blanket 4, a metal shock absorber 5, a fastening bolt 6 and a compression nut 7. The traveling wave tube 1 is a commonly used noise generating device. A window is opened at the installation part of the quartz window for the installation of the quartz window. The quartz window 2 is a rectangular glass made of quartz. Same size. Bracket 3 is two identical U-shaped grooves with a width of about 60 mm, and the material is the same as that of a traveling wave tube. Each bracket has five equally spaced threaded holes.

[0023] The insulation blanket 4 is a flexible pad processed b...

Abstract

The invention relates to the technical field of structural thermal noise composite environment tests, in particular to a device and method for mounting a high noise resistance quartz window under a high temperature environment. The mounting device comprises brackets (3), thermal insulation felt (4), metal shock pads (5), fastening bolts (6) and gland nuts (7). The brackets (3) are U-shaped groove components and are arranged on the upper side and the lower side of the window of a mounted object (1), and the two brackets (3) with opposite openings are mounted to be used for constraining the quartz window (2). The thermal insulation felt (4) is arranged between the quartz window (2) and the brackets (3) in a cushioned mode. In the horizontal direction, the metal shock pads (5), the fastening bolts (6) and the gland nuts (7) are used for fixing the quartz window (2). By the adoption of the device and method, the mounting stress caused by thermal deformation of a traveling-wave tube can be relieved, meanwhile, stable pretightening force can be provided under the high temperature environment, and the integrity of the thermal noise test system is guaranteed.

Description

technical field [0001] The invention relates to the technical field of structural thermal noise compound environment test, in particular to an installation device and an installation method of a quartz window resistant to strong noise in a high temperature environment. Background technique [0002] In the optimization design and performance assessment of the aircraft's thermal protection structure and engine air intake, it is necessary to carry out a large number of thermal and noise composite environmental verification tests. At present, the thermal noise test device mostly adopts the combination form of radiation heater and traveling wave tube system. Since the noise load and thermal load act on the surface of the aircraft structure on the same side during the actual flight, in order to realize the simultaneous application of thermal load and noise load on the same side of the flight structure surface, the radiation heater is passed through the traveling wave tube to the t...
