Abstract: This study focuses on afterburner turbofan engine weight estimation for fifth generation fighter aircrafts. Model developed in this study by investigating 26 engine cases categorised by the criteria the requirement of selection amongst to engines expected to be used in fifth generation fighter depend on four parameters with ≈ ±25% error. Technology level effect engine weight strongly so parameter reflect technology level is determined based on new technology engines used in fifth generation fighter aircraft by statistical method. Model reflect technology level is expected to be used in conceptual design stages of fifth generation fighter engine.
Keywords: fifth fighter aircraft; thrust/weight ratio; afterburner; turbofan.
