- Title
MATHEMATICAL MODEL FOR A JET ENGINE WITH COOLING FLUID INJECTION INTO ITS COMBUSTOR.
- Authors
TUDOSIE, Alexandru-Nicolae
- Abstract
The paper deals with an aircraft jet engine with cooling fluid injection into the rear part of its combustor, meant to temporarily increase its thrust, treated as controlled object. The author has established system's motion equations, consecutive to the new gas-dynamic and fluid mechanics conditions. Using the equation system, the author has obtained engine's new structure matrix description, as well as its transfer functions. A study concerning its time behavior was performed (about its speed, combustor temperature and thrust) and some conclusions were presented, comparing to other cooling fluid injection methods results. The paper is useful for students and researchers in their jet engine automation studies and may be improved by considering the flight regime influence.
