DETERMINING THE JET NOISE OF TURBOJET ENGINE
Dragoljub Vujić Branko Kajić This paper analises the jet noise of turbojet engine in time domain. The application of an empirical method for its determining is also treated. The sound pressure levels of a plane ground based on analytical expressions are given and compared to the measured values. The values of sound pressure levels around the two double flow turbojet engines on the maximum operating mode are also given here. Ključne reči: turbojet engine, acoustics, noise. |
