Abstract

The invention discloses a combined noise and static pressure loading device. The noise and static pressure combined loading device includes a traveling wave test assembly (1) and a static pressure loading assembly (2); the traveling wave test assembly (1) includes The first diffuser section (11), the second diffuser section (12) and the test section (13); the first diffuser section (11) is an index horn, and the big end of the first diffuser section (11) is in contact with the described first diffuser section (11). One end of the test section (13) is fixedly connected; the second diffusion section (12) includes a large end opening and a small end opening in the opposite direction, and the small end opening of the second diffusion section (12) is connected to the The other end of the test section (13) is fixedly connected; the static pressure loading assembly (2) is used to apply a static pressure load to the test piece. The beneficial effect of the present invention is that: the noise load is applied to the test piece by the traveling wave test assembly, and the static pressure load is applied to the test piece by the static pressure loading assembly, so that the joint application of noise and static pressure load can be realized.

Description

technical field [0001] The invention relates to the technical field of aviation noise and static pressure combined loading test, in particular to a noise and static pressure combined loading device. Background technique [0002] Under different working conditions, the structure of the new generation of aircraft is subject to the combined effects of noise and static pressure, which will aggravate the damage of the aircraft structure and shorten the service life of the aircraft. And under different operating conditions, it needs to bear the corresponding positive pressure or negative pressure load. Contents of the invention [0003] The object of the present invention is to provide a combined noise and static pressure loading device to solve or at least alleviate at least one of the problems in the background art. [0004] The technical solution adopted in the present invention is: to provide a combined noise and static pressure loading device, including a traveling wave te...
