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

open access: yesAerospace
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 ...

An Estimate of the Influence of the Compressor Stability Margin on the Pick-Up Time of a Turbojet Engine

open access: yesEngineering Transactions, 1991
The relations are derived enabling to estimate the acceleration time of the turbojet engine rotor set. The terms are established allowing for the determination of the effect of individual operational and structural engine parameters upon the time needed

Initial Flow Matching Results of MHD Energy Bypass on a Supersonic Turbojet Engine Using the Numerical Propulsion System Simulation (NPSS) Environment [PDF]

open access: yes, 2010
Preliminary flow matching has been demonstrated for a MHD energy bypass system on a supersonic turbojet engine. The Numerical Propulsion System Simulation (NPSS) environment was used to perform a thermodynamic cycle analysis to properly match the flows ...

NSEG, a segmented mission analysis program for low and high speed aircraft. Volume 1: Theoretical development [PDF]

open access: yes
A rapid mission analysis code based on the use of approximate flight path equations of motion is presented. Equation form varies with the segment type, for example, accelerations, climbs, cruises, descents, and decelerations.

Self-tuning speed and flow control of micro turbojet engines based on an improved evolutionary strategy

open access: yesAutomatika
At present, the controllable parameters of micro turbojet engines in engineering applications are mainly speed-fuel flow (hereinafter referred to as flow) control, in which closed-loop proportional–integral–derivative (PID) control is mostly used to ...
