Theoretical investigation of acceleration of a turbojet engine

, 1947
The failure of turbojet aircraft propulsion units to accelerate rapidly to high thrust operation when emergencies arise in slow speed flight has restricted their use in aircraft applications, and has also concentrated considerable attention upon their acceleration characteristics in an effort to produce better results.

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

Engineering 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

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

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

Automatika
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 ...
