TURBOJET, METHOD OF TURBOJET TESTING (VERSIONS) AND METHOD OF TURBOJET PRODUCTION, METHOD OF TURBOJET INDUSTRIAL PRODUCTION, METHOD OF TURBOJET OVERHAUL, AND METHOD OF TURBOJET OPERATION Russian patent published in 2013 - IPC G01M15/14

Abstract RU 2487334 C1

FIELD: engines and pumps.

SUBSTANCE: set of inventions describes the methods of testing turbojet for gas-dynamic stability by developed input aerodynamic device furnished with extending interceptor and calibrated scale with arrest of boundary and mid positions in airflow. Developed versions of experimental estimation of gas-dynamic stability are applicable in pilot, experimental-industrial, commercial production and operation to increase reliability of gas-dynamic stability estimation and definition of boundaries of engine changing in surge and to set safety margin equal to 2-5% of critical value.

EFFECT: simplified process, lower costs and higher accuracy and reliability.
