Some Aspects of the Control of Multishaft Jet Engines 670139
Methods of controlling multishaft jet engines are discussed, together with the reasons which dictate the type of control used. These cover control of compressor geometry including variable stators and compressor bleed, control of engine fuel flow including limiting trims, and control of the afterburner including afterburner fuel flow and final nozzle area. The particular problems during transient as well as steady-state engine conditions have been considered. The advantages and disadvantages of various types of control are presented, and these arguments are used to evolve a number of guiding principles in the control of this type of engine.
