AERODYNAMIC AIRCRAFT MODEL FOR STUDY OF PRESSURE DISTRIBUTION ALONG SURFACE IN AERODYNAMIC TESTS WITH AFT JET ENGINE JET IMITATION Russian patent published in 2016 - IPC G01M9/08 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement equipment, namely to aircraft aerodynamic models for research of pressure distribution on thin-wall model surface, tested in aerodynamic tunnels under condition of aft rocket engine jet simulation. Invention summary consists in fact that to drain holes, drilled on aerodynamic model streamlined surface intended for pressure distribution measurement along surface, in thin-wall shell housing curvilinear channels are made within shell thickness. Measured pressure, perceived by drain holes, is supplied into channels, which are laid to side holder attachment point inside shell and here are coupled with drain tubes, connecting pressure measuring devices, for example, multitube pressure gage, with channels outlet cross-sections.

EFFECT: technical result consists in improvement of measurements accuracy and validity.
