Fuel Injection Dosage Control System with Air Pressure Correction

摘要

This paper deals with a fuel injection system for an aircraft engine, which operates with respect to the throttle's position. Its operation is assisted by an air-pressure-corrector, in order to correlate the fuel injection with the burned gas flow rate. The author has established the mathematical model and has determined the block diagram with transfer functions. Based on the stability studies, several useful conclusions were drawn, regarding system's behavior and system's constructive parameters. System's model and its time behavior can be useful for further studies concerning aircraft engines with afterburning.
