Embodiment Construction
[0021] In order to make the implementation purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the accompanying drawings in the embodiments of the present application.
[0022] In this application, the rectifying blade that simulates the swirl flow field and the measurement section that simulates the high-temperature uniform flow field are integrated to form a new high-temperature measurement structure that can simulate the afterburner inlet swirl flow field. The unilateral fixed connection method reduces the length of the welding seam of the rectifier blade and reduces the risk of deformation of the rectifier blade during the installation process. The connection between the rectifier blade as a whole and the measuring section adopts the structure of sliding pins and curved plates to solve the problem of high temperature expan...

The invention discloses a dual-channel high-temperature measurement structure for simulating an afterburner inlet flow field. The dual-channel high-temperature measurement structure comprises a front insertion ring, a front flange, an outer sleeve, an inner sleeve, a test sensing part, a rear flange, a test piece, a curved plate, a rectifying blade, a sliding screw and a rear insertion ring, the front mounting flange and the front plug-in ring are connected with equipment, and the rear flange and the rear plug-in ring are connected with a test piece; the outer sleeve and the inner sleeve are connected through a plurality of connecting support plates which are arranged in the circumferential direction, and the inner sleeve and the inner cone are connected through rectification blades; the radial direction of the rectifying blade is connected with a sliding pin through a connecting support plate, the front end of the axial direction of the rectifying blade is fixed through a curved plate, and the rear end of the rectifying blade is connected through an annular plug-in structure test piece, so that a connecting structure with three-side limiting and single-side fixing is formed; the test sensing part penetrates through the outer sleeve and the inner sleeve and is used for measuring parameters such as airflow temperature, pressure and airflow angle of an inner channel formed between the inner sleeve and the inner cone.
Description
technical field [0001] The application relates to the technical field of aero-engine testing, and in particular, to a dual-channel high-temperature measurement structure for simulating the inlet flow field of an afterburner. Background technique [0002] In order to simulate the working state of a real afterburner, it is usually necessary to adopt a measurement structure that can accurately simulate the flow field at the inlet of the afterburner. However, the existing afterburner inlet measurement structure can only simulate the temperature and pressure parameters of the afterburner inlet flow field. During the test, the effect of the afterburner inlet swirl on the operation of the afterburner cannot be simulated. SUMMARY OF THE INVENTION [0003] The purpose of the present application is to provide a dual-channel high-temperature measurement structure for simulating the inlet flow field of an afterburner, so as to solve or alleviate at least one problem in the background...
