DEVICE FOR INVESTIGATING NEAR FIELD OF MODEL PRESSURE IN A WIND TUNNEL Russian patent published in 2019 - IPC G01M9/06 

FIELD: test technology.

SUBSTANCE: invention relates to aerodynamics and is intended for investigation of near field of model pressure at supersonic flow in wind tunnel. Device comprises shock wave generator (model), surface with barosensitive coating applied parallel to flow in near zone of model of aircraft, ultraviolet emitters, at least one signal recorder from a barosensitive coating (digital camera) for detecting luminescence intensity of a barosensitive coating, as a surface for application of a barosensitive coating, a section of the wall of the working part of the aerodynamic pipe is used. At that, length, width of section with applied coating, shortest distance from wall of working part of aerodynamic pipe to spout model, as well as the distance x from the front point (spout) of the projection of the model on the wall of the pipe to the area with the barosensitive coating applied, are determined by corresponding expressions which take into account the model dimensions and airflow blowing modes of the model.

EFFECT: providing high quality of experiment.
