This chapter deals with some intensive methods regarding aircraft gas-turbine-engine performance enhancement, which are suitable alternatives for the most common temporarily thrust increasing method—the afterburning. Coolant injection method, into the compressor or into the combustor, realizes the desired thrust increase for a short period, when the flight conditions or other aircraft necessities require this. Both methods were studied from aircraft engine’s point of view, considering it as controlled object. New engine’s mathematical model was built up, following the thermo- and gas-dynamics changes and some quality studies were performed, based on engine’s time behavior simulations; some control options and schemes were also studied. Quantitative studies were based on the model of an existing turbo-engine; mathematical model’s coefficients are both experimentally determined (in the Aerospace Engineering Division labs) as well as estimated based on graphic-analytic methods. This approach and the presented methods could be applied to any other turbo-jet engine and used even in the stage of pre-design of a new engine, to estimate its stability and quality.
KEYWORDS
From the above the study it clearly shows that · The heat transfer value (Q) is in higher side when we use the ethylene glycol as coolant. · The Heat flux is in higher side when we use the ethylene glycol as coolant. · The static enthalpy value is in higher side when we use only water as coolant. · The effectiveness is also in better side when we use the ethylene glycol as coolant. · When we use propylene glycol the pressure drop is more. These are the finding which we studied from this study.
