Abstract

The invention discloses a noise and static pressure joint loading device. The noise and static pressure joint loading device comprises a traveling wave experiment assembly (1) and a static pressure loading assembly (2), wherein the traveling wave experiment assembly (1) comprises a first diffusion section (11), a second diffusion section (12) and an experiment section (13); the first diffusion section (11) is an exponential horn, and the big end of the first diffusion section (11) is fixedly connected with one end of the experiment section (13); the second diffusion (12) comprises a big end opening and a small end opening in opposite directions, and the small end opening of the second diffusion section (12) is fixedly connected with the other end of the experiment section (13); and the static pressure loading assembly (2) is used for exerting a static pressure load to an experimental sample. The noise and static pressure joint loading device disclosed by the invention has the beneficial effects that a noise load is exerted to the experimental sample through the traveling wave experiment assembly, the static pressure load is exerted to the experimental sample through the static pressure loading assembly, and the joint exerting of the noise load and the 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...
