A Hybrid Algorithm Modeling on Test-Bench Data for Light-Duty Afterburning Turbojet Engine

Aerospace
For highly maneuverable aircraft, the afterburning engine serves as a core and critical component. Due to the complex structure of the afterburner and the strong coupling among parameters, mechanism-based modeling of afterburning engines remains ...
