Hypersonic wind tunnel experiment module

Abstract

The invention discloses a hypersonic wind tunnel experiment module which comprises an experiment module body. A module door is arranged on the experiment module body. A cross section of the experiment module body along a longitudinal direction is a circle. The module door is an arc-shaped a flap cover which is connected with the experiment module body in a movable mode. When the experiment module door is in a closed state, the center of the cross section arc of the arc-shaped flap cover is in the center line of the experiment module body along the longitudinal direction. Due to the fact that the arc-shaped flap cover is connected with the experiment module body in a movable mode, the opening space of the experiment module body is large when the arc-shaped flap cover is opened, the experiment module body is suitable for large laboratory models getting in and out, and therefore the technical problems that the existing experiment module body is difficult for the large laboratory models to get in and out, labor intensity is large and efficiency of experiments is low are solved. The hypersonic wind tunnel experiment module is large in opening space, capable of facilitating getting in and out of the large experiment models and adjusting space postures of the large experiment models, improving efficiency of wind tunnel experiments and enabling experimental operations of operators to be convenient.

Description

technical field [0001] The invention relates to the field of wind tunnel experiments, in particular to a hypersonic wind tunnel experiment cabin. Background technique [0002] The wind tunnel experiment is based on the relative principle of motion. The experimental model or object is fixed in the artificial environment on the ground, and the airflow is artificially created to simulate various flight states in the air and obtain experimental data. Wind tunnel experiments are widely used in model experiments of missiles, hypersonic vehicles, and aerospace aircraft, and are very important ground test equipment in the aerospace field. Hypersonic wind tunnels generally include heaters, nozzles, experimental cabins, diffusers, ejectors (or vacuum tanks), air source systems, control systems, etc. The experimental cabin is the place for the experimental model and an important part of the wind tunnel. , to meet the needs of different experimental models and experimental tasks.
