SINGLE-SPOOL JET ENGINE FOR AIRCRAFT WITH AFTERBURNING SYSTEM
Journal Title: ANALELE UNIVERSITATII DIN CRAIOVA - Seria Inginerie electrica - Year 2010, Vol 34, Issue 34
Abstract
This paper deals with a single-spool single jet engine with afterburner for thrust augmentation. The afterburning system consists of a special combustor with its own fuel pump, turned round by the engine’s spool and operating with respect to the gas-turbine’s pressure ratio. The authors have built the mathematical model for the interconnected engine-afterburning system (EAS), based on the simplified mathematical models of the main parts of the system, models already determined and presented by other papers mentioned in the references section. The EAS was identified as controlled object and described by its mathematical model, as well as by its block diagram with transfer functions. Based on these elements, the authors have studied EAS time behavior, by studying its quality, which means its time response, performing some computer aided simulations; the simulations were based on some co-efficient, experimentally determined and calculated for the VK-1F jet engine. The paper is based on some similar works of the first author, as well as on similar works presented in the reference list, about aircraft jet engines and engines’ main parts as controlled object(s). The used methods, as well as the conclusions and results, can be extended in further works, concerning multi-spool engines with afterburning systems.
