Resumen

KHATCHATOURIAN, Oleg A  y  NEVES, João C.M. Application of the Turbofan Linear Model to the Analysis of its Functioning with Afterburner. Inf. tecnol. [online]. 2007, vol.18, n.2, pp. 3-15. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642007000200002.

The purpose of the presented work was a comparison of an efficiency of Mechanical Flame Holders system and Aerodynamic Flame Holders system for turbofan engine afterburner. The linear mathema-tical model of the turbofan engine was developed to analyze an influence of air compressor-bleeding for Aerodynamic Flame Holders system on the turbofan engine characteristics. An evaluation criterion was proposed to compare an efficiency of Mechanical and Aerodynamic systems. An influence of dif-ferrent parameters on this criterion was analyzed. The factors that cause pressure loss accretion during afterburner down-time, increase the region where the use of Aerodynamic Flame Holders system is preferable in comparison with Mechanical Flame Holders system. It may be concluded that this system can be recommended as moderate thrust augmentation reserve unit for use in emergency operation (insufficient take-off distance, engine failure) or in short- time operation (to break the sound barrier, to reach the most height, take-off).

Palabras clave : turbofan; afterburner; aerodynamic holder; mechanical holder.
